1. There are several types of Solar lighting

Solar lighting uses solar energy as the energy source. It realizes photoelectric conversion through Solar cells. During the day, use batteries to accumulate and store electrical energy. At night, the electro -optic source is powered by the controller to achieve the required functional lighting system. It is a green and environmentally friendly lighting method.solar energy is renewable energy, which is of great significance for sustainable development. There are many types of Solar lighting systems. According to different classification methods, they can be divided into:

1. According to the power supply of Solar photovoltaic lighting

(1) Independent Solar photovoltaic lighting: Taking solar energy as energy, lighting devices containing one or more lighting components in Outdoor mesh and independent use of more Solar batteries and batteries need to be configured to store energy.

(2) Scenery Solar lighting: Add wind generator to the independent Solar lighting device and use it together with Solar cells to reduce the capacity of Solar batteries.

(3) Renewal lighting of solar energy and municipal electricity: solar energy is the main energy source for lighting for lighting that night. When the battery energy storage is insufficient on the rainy day, the lighting device of the municipal power is powered.

2. Supply the power of Solar photovoltaic lighting sources according to Solar photovoltaic lighting sources

(1) Direct power supply: The electric storage sent by the Solar cell board is in the battery, which is directly powered by the battery to the light source.

(2) Indirect power supply: that is, the inverter power supply is converted to the transition power through the inverter, and then the power supply will be powered by the light source. Compared with the direct power supply, there will be 10-20 % power loss.

3. According to the occasions and functions of use

It can be divided into Solar signal lamps, Solar lawn lamps, Solar Landscape lights, Solar lamps, Solar street lights, Solar insecticidal Lights, Solar advertising light boxes, Solar flashlights.

2. What are the main points of the Solar lighting system?

When designing the Solar lighting system, there are many factors that need to be considered. Among them, the main design points that need to be considered are:

1. Solar radiation volume

That is, the local Solar standard peak sunshine time, calculate the required capacity of Solar cells and batteries based on the sunshine time and radiation volume.

2. Light source power

When designing a Solar lighting system, the light source power of Solar lamps will affect the stability of the lighting, lighting time, and the entire Solar lighting system.

3. Working hours

It is mainly to determine the length of time for Solar lamps to work, thereby calculating the capacity of power consumption and the capacity of the charging power supply of Solar battery components.

4. rainy days

Solar lamps need to be stored in the weather with the sun. If it wants to use it normally, it needs to consume the energy stored before. The length of the number of continuous rainy days determines the capacity of the battery and the Solar battery component required for the recovery of the battery capacity after rainy days.Power; in addition, consider the number of days between two continuous rainy days.

5. Solar lighting lamp parameters

Including functional parameters: battery component, controller, and battery of Solar lighting lamps.

Principles of fruit trees pruning

When trimming the fruit tree, the fruit farmers should not be blindly carried out. They should follow the three principles of "trimming the trees, the shape of the branches, the combination of the length, the combination of length, and the combination of light and weight."Among them, "because the tree is trimmed and the branches are made" refers"Combination in length" means that when the fruit trees are trimmed, the factors such as plants and fruits should be considered. The trimming should be discussed from the long process.Mainly, the result of the trimming of the tree is mainly based on growth and results; "mainly light and weight combination" means that when pruning, especially when the young trees are trimmed, the amount of pruning should be reduced to avoid too much trimming too much pruning too much pruning.The phenomenon of plant growth and suppression occurred.

fruit tree trimming technology

Although the trimming of fruit trees is divided into dormant trimming and growth pruning, the purpose of the two pruning is very different (the pruning period is mentioned by the specific purpose of the two), so there is a large difference in the trimming technology.The specifics are as follows:

Trimming during dormancy: short -cutting, recovery, long release, sparse branches, etc.

Trimming during the growth period: buds, carving buds, removing cute, topping, clinging to branches, twisting, pulling branches, removing, and other branches.

Short interception (short shear)

1. What is short -cut

It is a part of the year of the year.

2. Short -cut effect

(1) Promote the growth of branches and expand the crown

The germination and growth of the buds under the short -cutting of the mouth is conducive to expanding the canopy.It is mostly used for the pruning of the central dry and extended branches, the main branches extend the branch, and the side branches extend the branches.

(2) increase the amount of long branches

The short -term sprout rate and branches are significantly increased, which is conducive to increasing the amount of long branches. It can be used for the cultivation of large and medium -sized branches and the adjustment of the branches, and the restoration of the tree.

(3) Short cutting can shorten the axis, shorten the distance of nutrient transportation, and help promote growth and update.

(4) It can enhance the top advantage.

Cut

1. What is shrinking shear

Cut to a part of many years.When the thicker cuts are cut, first cut or short, and then retract when the branches are weak. Such a trimming method composed of two cutting treatment is called shrinkage.

2. The function of shrinkage

The role of resurrecting and changing the growth direction of the branches is conducive to ventilation and light transmission and weakening the mother branches.

The promotion effect of shrinkage -is often used in the renewal of the resulting branches and the weak branches.

The weakening effect of scissors -commonly used for power regulation, control or weakening the auxiliary support branches between backbones.

For example: weak branches shrink cutting

The weakened branches are mostly a single branch extended branch.When shrinking, shrink to the back of the strong branches or can be raised by raising angle.

3. How to apply

The renovation of many years of auxiliary branches is the result branch group. As a result, the branches are renewed and updated, the length of control of the backbone branch, and the size of the crown.

Scrutiny

ScrutinyMeaningTheRemove the branches from the base.

Sparse cutting

1. Reduce branches and improve the light in the crown, which is conducive to promoting results.It is often used to remove competitive branches, upright branches, overlapping branches, cross -branch, etc.

2. Weaken the growth trend of mother branches.It is often used to regulate the balance between the backbone, stronger and more sparse, weak or less sparse.However, if flower buds, result branches, or invalid branches are removed, it will enhance the power of the overall and mother branches.

3. The wound formed on the mother branches can affect the transportation of water and nutritional substances. It can use sparse shear to control the upper branches and the growth of the lower branches to enhance the growth of the lower branches.

Scrutinyofapplication

Shutdles are densely sprouting, strong branches, and dense branches.For Wangshu and Wangzhi, you want it to ease growth and balance the branches.Remove the dead branches, diseases and insect branches, long branches, drooping branches and aging branches.

Long -term

1. What is long -sized

That is, the branches of raw branches will not be trimmed in the year, and the top buds are retained to allow the top buds to make branches.More use for young trees.

2. The role of long release

Proper long release is conducive to alleviating trees and promoting the formation of flower bud differentiation.

3. How to apply

Two upright branches, competition branches, and long branches cannot be released.

The golden mean branches, horizontal branches, and oblique branches can be long.

Tune

(Artificial changes in the growth direction of the branches)

1. What is Qu Zhizhi

Bend or change the annual or perennial branches, change its growth direction, and make full use of the space to promote the results of the tree.

2. The role of song branches

It can change the top advantage, ease the branches, increase the bud, reduce the power of the branches, increase the short to the number, which is conducive to the flowers. At the same time, it can also make full use of the space to make the branches evenly distributed and good light.

3. How to apply

The annual development of branches or perennial auxiliary branches, and branches can be tacitated to promote flowers.

Carving and multi -trail carvings

1. What is engraving and multi -ring carving

The horizontal cutting cortex is used to the wooden part above or below the bud branch, which is called engraving.

The multi -tract carrier is cutting a week on the branches with a knife or cutting ring for a week, and it can significantly increase the germination rate.

2. The role of engraving and multi -tract carvings

Before and after spring germination, carved injuries above the branches can prevent the top of the top nutrients from being transported downward, which can promote buds, branches and growth under the incision.

Wipe buds and sparse shoots

1. What are the scratching and sparse tips

Scratching buds: erase or cut it after germination.

Sparse shoots: For the densely growing annual branches, cut off a few from the base, that is, the dense new shoots are removed.

2. The role of buds

Select the best to go inferior, in addition to dense and leisure, save nutrients, improve light and improve the quality of retaining branches.

Tool and cutting

1. What is topping and cutting tips

Tool: remove the tip of young tenderness.

Cut the tip: also cut off the young shoot

2. The role of topping and cutting tips

(1) Promote the germination of side buds and secondary growth, and increase the amount of branches.

(2) Promoting the formation of flower buds is conducive to early results.

(3) Improve the fruiting rate.If the grape flowering period is top, it can significantly increase the seat fruit rate.

(4) Promote the enrichment of the buds.The new shooting of the new shoots that will stop growing in autumn can promote the buds to be conducive to overwintering.

Twist

1. What is a twist?

When the new shoot is not yet woody, the new shoots on the back, the competitive branches of extended branches at all Levels, and the temporary branches growing in the back, at about 5 cm at the base, gently reverse 180 degrees, so that the wooden and the skinny parts are affected by both the wood and the cigarette parts. Mild damage, but not broken.

2. The role of twisting

Promote the formation of flower buds.

Take the branch ()

1. What is the branch

In the long term of the new shoots, it is bent from the base to the top with the hand, hurting the wooden part, and the sound is not touched.

2. The role of the branches

You can open the angle of the branches, improve the bud rate of the branches, promote the formation of flower buds and medium short branches, and cultivate the results of the result branches.

3,Rotatingapplication

The main objects are more upright branches, competitive branches, auxiliary nursing branches, etc.

Ring peeling

1. What is ring peeling

It is peeling off the branches.

2. The role of ring peeling

The leather part is the main channel for organic substances along the entire plant.Circular stripping is used to temporarily interrupt the upper and lower transportation of organic substances to achieve the role of inhibiting nutrient growth, promoting flower bud differentiation, and improving the fruit rate.

3,Circular peelingprecautions

(1) Circle peeling time

Related to the purpose.Promoting flower bud differentiation should be carried out before flower bud differentiation, and the increase in the fruiting rate should be carried out before and after the flowering period.

(2) The appropriate depth of ring peeling

Cut until the wooden department.Too deep and easy to hurt the wooden parts will severely suppress growth.Seriously causes the ring to divest.It is no effect if it is shallow.

(3) Pay attention to protecting the wounds of the ring peel and prevent the harm of diseases and insect pests.

4. Circle peeling object

Wangshu and prosperous branches are carried out, and the weak trees and branches are not carried out.

Summary of fruit tree Revision

Talking about the fruit trees is very old, there are skills to master the laws.

First of all, use high -tech, keep the trimming time in mind.

In the spring, scratching the buds in summer, and the winter cut in the hat in autumn.

Cut the fruit trees in the four seasons, and it is expected to yield every year.

fruit trees should be trimmed five to see, and the plan is determined after watching.

At first glance, the trees should be appropriate.

Second, look at the variety of fruit trees, and the pruning method should be clear.

Three look at the age of the tree and small, and the trimming should be divided into young and old.

Fourth, look at the trees and weakness, and the weak trees are cut and ease.

Five views of flowers and less flowers, there are skills under the scissors.

The diseased and insects were cut first, and the main branch was the first.

Be careful when you stay, do not move casually.

Qiu went to Da Zhi the most secure and wound healing the safest.

If the main branch is left, there must be conditions, and you must look at it from the direction.

The main branches at all Levels are determined, and they are looking for large and small branches.

The inner hall is to be removed upright, and there is no light without light.

You can say the growth position, the scissors follow your head.

Don't bend the center of the center, always grow in the middle.

The main branches at all Levels are extinguished, and the side branches grow on both sides.

If you want to get a large and high yield, the identification of flower buds is Guan Jian.

The flower bud head is large, and the small pointed head is the leaf bud.

The flower buds are not obese, and the flower bud leaf buds are not like.

As a result, there were three types of branches, long and short and short branches.

Too dense places should be removed, don't cut short branches.

After cutting, take a closer look.

In this way, the trimming is relatively complete, and the low production capacity will change the high yield.

The specific trim is like a housekeeper.

The fruit trees are like a big family, and their children and grandchildren are melting around their knees.

Family rules are strictly associated with fruits, and the rules are chaotic.

As a fruit tree mediation person, mediation disputes.

Zhongan is better than the old ancestor, and his body is very upright.

The waist was weak and deceived, and the head was crooked and the shoulders were obliquely replaced.

Zhong Gan was born with his son, and the boss had three feet away from the ground.

The child is a few generations than the ancestors, and the figure is thinner than the ancestors.

If it is as thick as the ancestor, it will be more sparse.

The son arranged in an orderly manner and rose around the ancestral spiral.

The small pagoda type is a small pagoda.

The distance between the layer is opened, and there is light in the inner hall.

Brother is in the lower brother, and the brother will always give up the brother.

If the brother is bigger than his brother, the consequences must be terrible.

Brother was weak, and his brother was prestigious.

This behavior is terrible and should be removed from the base.

If the space is large, he can also keep him.

Rebelling his grandson.Peel at the base.

The son gave birth to a grandson, and his grandson had to control him even more.

You can't just ride the door or stand on the back of his dad.

Can't run side by side with dad, you can't stay at home.

Before and after, he lives in an orderly manner, and the brothers are orderly.

Living at the top of the top is high, and the body is Slim.

Once you get fat with your dad, you will also be driven away.

As a fruit tree pruning, the long and young are clearly ranked.

Mo regards his son as a grandson, and his brother and brother must divide it.

The grandparents were rowed well, and the trees were graceful with fruits.

If your grandchildren come to chaos, your fruit tree is finished.

The quality of the fruit is not good, so that you can wipe your tears after autumn.

I do nt know what to say, right?

1. What is the difference between color -changing Cycling glasses and polarizing Cycling glasses

There are many types of Cycling glasses. The mainstream is two types of color -changing Riding glasses and polarizing Cycling glasses. What is the difference between these two Cycling glasses?The difference between Cycling glasses and polarization is mainly:

1. Different principles

Trimous glasses are made by the principle of decomposition of halogen silver. When absorbing ultraviolet rays, silver and silver decomposition, silver atom and ultraviolet rays, the light transmission rate of glasses changes, and the color changes; polarizers are based on the polarization principle of light.When it is made, when the vibration plane of the light is parallel to the polarized shaft, the polarized light filter can make the polarization light through.

2. Different performance colors

The color changing glasses will be darkened when the sun is exposed, and the color will be restored when there is no strong light when entering the room; polarizing glasses generally will not change the color with the sun.

3. Different degrees of blocking light

Discounted glasses can only reduce the intensity of glare, ultraviolet light, and cannot completely block these harmful light; Polarized glasses can completely block the dazzling glare caused by various factors such as scattering, flexion, and reflection.

The above is the main difference between the two Cycling glasses. So which is the best color -changing mirror and polarizing mirror?

2. Choose polarized light or discoloration of Riding glasses

Riding glasses are one of the essential equipment for cycling movements. Some riders think that polarizing Cycling glasses is better, and some riders prefer to change color ride glasses. So is it good for Riding glasses to change color?

Generally speaking, the two types of Cycling glasses have their own benefits. Polarized Riding glasses can filter the UVA and UVCs of the sun, and can filter the water surface and glass reflex light from special angles such as cycling strabismus, which is suitable for the water under the sun.Ride on the road with many cars; and the color -changing Cycling glasses can change with the changes in ultraviolet rays and temperature in the environment, thereby protecting our eyes, but the filtering effect of ultraviolet rays is not as good as polarizing Cycling glasses, and it does not have it.The polarizing function is relatively better.

However, for conditional riders, it is better to prepare a pair of Polarized glasses and a pair of colorful glasses. You can also buy the ride glasses that can replace the lens and prepare two lenses.

1. Why do greenhouse greenhouses use Shading nets

1. Over -Shading effect

The Shading net reduces the intensity of the light in the greenhouse. The larger the density specifications, the better the Shading. The same specifications are better than silver -gray Shading.

2. Cooling effect

The temperature in the shed decreased due to the coverage of the shade net, and the cooling of the surface and soil farming layer was ideal. At 10 am -at 2 am, the temperature of the upper part of the greenhouse was 37-40 C, and the temperature around the surface plants was 22-26 C. The soil was soil.The temperature is between 18 and 22 C, which is suitable for crop growth.

3. Baoyao anti -strict rain

The evaporation in the shed decreases, the soil water content is higher than the dew, and the surface soil is moist.Because the Shading net can break down the rainstorm into drizzle, the free leaves are injured by heavy rain, and the soil is not easy to end. The gap is large and the ventilation is good.

Based on the above effect of the Shading net, many greenhouse vegetable growers generally choose to cover the Shading net in the greenhouse plastic film. In this case, the Shading effect is better, which is more beneficial for crop growth.

Second, the Shading net is placed inside the greenhouse or outside

1. When the Shading net is placed outside the greenhouse, because it directly blocks the sunlight outside the greenhouse, it makes its light calories not transmitted to the inside of the greenhouse, thereby achieving a certain cooling role while covering the light, thereby playing a certain cooling role, therebyIt is also more conducive to avoiding the radiation of strong sunlight, thereby reducing the impact of high temperature on vegetable growth.

2. When the Shading net is placed inside the greenhouse, the Solar light can still enter the interior through the greenhouse film, so that the heat will also be brought in, so this method of use will not change the internal temperature, but it can cover the Solar ray of the sunlight.The impact on vegetables is suitable for vegetables that require temperature but also want to avoid ultraviolet irradiation.

Only by mastering the correct usage method and clearing the different functions produced by different use methods can we play the role of the shade net to the point, which is more conducive to the good and rapid growth of vegetables, thereby bringing a considerable economy to the growers to bring a considerable economybenefit.

1. How much is the price of a fishing rod?

The fishing rod is a fishing rod used during Taiwan fishing. It is characterized by long sections, lighter, and thin diameter. For fishermen who love Taiwan fishing, it is necessary to buy a quality and work well.So how much is a fishing rod?

The price of the fishing rod is affected by many factors, which is generally more than 200 yuan, but the different prices such as materials, brands, and length are also very different:

1. Material: How much money does a table fishing depends on the material? For example, the fishing rod of glass fiber tables under the same conditions is definitely cheaper than the carbon fiber table fishing rod.The above carbon cloth) cheap.

2. brand: How much money does a Taiwan fishing rod depends on the brand? Among them, the brand's fishing rod is basically more than 200 yuan, while the miscellaneous table fishing rod may only be tens of yuan.

3. Level: How much money does the fishing rod depends on the length? The longer the length of the fishing rod on the same condition, the more expensive the price.The price of rice is about 699 yuan.

More fishing rod price reference & gt; & gt;

2. Is it necessary to buy expensive on the Taiwan fishing rod?

When buying a table fishing rod, many friends feel that the more expensive the fishing rod, the better, especially some novice friends, they will choose the expensive table fishing rod directly when they come up, but in fact it is unnecessary.

The less expensive of the table fishing rod is better, but it is suitable for the main. Different prices of Taiwan Fishing rods are mainly in terms of material, length, brand, etc. At actual use, some expensive Taiwan Fishing rods may not be as cheap as the cheap Taiwanese fishing rod.Suitable.Whether a fishing rod is easy to use depends on where fishing, what fishing, personal fishing habits, number of parameters of Fishing rods, etc., are not just known to just look at the price.

Many novices buy Fishing rods will also fall into the more expensive and better misunderstandings. In fact, for novices, the learning stage does not understand any feel, and it will not lift the rod.The fishing rod, so there is no need to buy expensive ones.

Of course, after being proficient, you can consider buying some expensive Table fishing rods. The materials and work are better. The fishing experience is relatively better, but the same is the more expensive and better. Pay attention to comprehensive consideration.
