1. There are several types of Gardening branches

1. Ordinary pruning trimming

Ordinary branches are generally cut off 3 cm, as long as they can be included in the cut mouth, they can be cut off.During the operation, hold the scissors with your right hand, and push the thick branches in the direction of the scissors with your left hand, and you can solve it. Do not twist the scissors left and right, otherwise it will affect the normal use.

2. Long branny pruning

The long -cut cutting scissors is crescent, the handle is long, and the branches within 1 cm can be trimmed briskly, which is suitable for the trimming of the shrub bush.

3. High branch cut

The branches are cut with a long -handed aluminum alloy long handle. When used, it can be adjusted according to the height of the trimming to cut the fine branches at the cut.

4. Daiping scissors

Dacian shear is also called hedge shear and long -blade shear. It is suitable for the trimming of hedges, spherical trees and shapes of seedlings. Its strip blades are very long, and the blade is very thin.The shoot.

2. How to buy pruning pruning

1. Select the scissors of the big brand.

If you want to buy a high -quality pruning pruning, when choosing pruning pruning, it is best to choose the branches of the big brands. Many branches of pruning manufacturers of many big brands.

2. Select the length of the corresponding scissors blade.

If you want to buy a high -quality pruning pruning, when you choose to repair, choose the length of the corresponding scissors blade.If you often repair those particularly rough branches, buy a little pruning of the blade mouth, otherwise, you can buy the short pruning and pruning of the blade mouth.

3. Is it convenient and comfortable to use locks?

If you want to buy a high -quality pruning pruning, when choosing pruning pruning, you must feel whether the lock is convenient and comfortable to use.Both unlocking and lock locks are relatively easy.

4. Good spring performance.

If you want to buy a high -quality pruning pruning, you must choose the pruning pruning with better springs when choosing pruning pruning, so in the process of buyingPerformance, if the springs of pruning pruning are relatively strong and stable during the opening and closing process, the quality of branches will not be too bad.

5. Choose easy to clean.

If you want to buy a high -quality pruning trimming, when choosing a repair part, it is best to choose those that are easier to clean, because the branches and cuts often trim the pruning strips, there will be some stains, choose those that are easier to cleanIt is not easy to leave stains on the scissors. For example, many pruning surfaces will have Tellon coating. This coating can effectively prevent scissors from rusting.

6. Choose steel pruning pruning.

If you want to buy a high -quality pruning pruning, when choosing pruning and pruning, special attention should be paid to the quality of branches and cutting tip. Generally speaking, many branches are used for steel.Choose the branches of imported steels. After the pruning of these materials is used for a long time, the branches of these materials are relatively large. In the process of usingThe quality is relatively guaranteed.

7. Choose hand -shaking frictions.

If you want to buy a high -quality pruning pruning, when choosing pruning and pruning, try to choose to shake hands and friction. There are more coarse branches in the process of pruning.If the friction is very large, the cutting of branches is not easy to slide during the cutting process.In addition, you can actually feel the branches and handshake. If it is more comfortable to use, it is not too large or too small. Such branches and cutting are more suitable.

8. Choose pruning pruning that is easy to hold.

If you want to buy a high -quality pruning pruning, try to choose pruning pruning that is easy to hold when choosing pruning.For example, some branches have only two handshake.It is best to choose those handshake with holes, so that there are pruning and pruning with holes.

1. Which of the Shading effect of aluminum foil Shading net and black net is better

1. Material comparison

Aluminum foil Shading net is a Shading material composed of multi -layer fiber mesh, aluminum foil, and PE anti -ultraviolet material. It has excellent ultraviolet -resistant, shielding, heat insulation and other properties, and has strong durability and compressive resistance.The black net is a Shading material made of HDPE material, which has the advantages of sunscreen, shielding, breathable, etc. Its advantage is that the price is cheaper and has good light transmission performance.

2. Comparison of Shading effect

The aluminum foil Shading net has a good Shading effect. Its special structure allows it to reflect the sunlight of the sun, reduce the direct radiation of the Solar, maintain temperature and increase water evaporation, thereby improving plant yield and growth quality.The anti -ultraviolet effect of this material is also excellent, which can effectively avoid the damage caused by ultraviolet rays to plants.The black net's Shading effect is slightly inferior to the aluminum foil Shading net, but for some occasions that need light transmission, the black net is a more suitable choice than the aluminum foil Shading net.

3. Select suggestions

When choosing a Shading material, we must first consider the application scenario. If the material is required to have anti -ultraviolet rays and Shading effects, it is recommended to choose an aluminum foil Shading net; if the material is better, you can choose the black net.In addition, the price of aluminum foil Shading net is relatively high. If the requirements are not high and the price is low, you can choose the black net, but you should pay attention to the quality of the material to avoid waste from buying inferior materials.

In summary, the aluminum foil Shading nets and black nets have their own advantages and disadvantages, and appropriate materials need to be selected according to actual needs.When purchasing, you should try to choose materials with quality and guarantee. Do not choose inferior products for cheap or other reasons, causing unnecessary economic losses.

2. How to distinguish the quality of the shade net

1. Material

The high -quality Shading net uses new polyethylene as the raw material, adding imported ultraviolet absorbers, antioxidants and good female mother production.

The inferior Shading net is made of recycling materials (old materials, flower materials) and inferior colors, and the ultraviolet absorbers and antioxidants are not added.

2. Appearance

The high -quality Shading mesh surface is flat, Smooth, shiny, uniform and clear with latitude and weft. In the sun, the color is black and black, the color is small, and the silk has no overlap.

The inferior Shading mesh surface is uneven, no gloss, no light, uneven latitude and weft, with gray black in the sun, large color difference, the silk mesh contains impurities, and the silk mesh overlap.

3, feel

High -quality Shading net feels soft, not rough, not stiff, and elastic.

The inferior Shading net has a rough feel, a bit stabbing, feels thick, and non -elastic.

4. Smell

The high -quality Shading net has no odor, and some are just a faint plastic scorching flavor.

The inferior Shading net is unpleasant, pungent, and plastic scorched flavor.

5. Quality

High -quality Shading nets have a Square gram of heavy gram, and the width and length are accurate. There are no holes in the mesh surface, no filament, strong single silk elasticity, and strong tensile ability.

The Square gram of the inferior Shading net is not standard, the width length is inaccurate, the mesh is hole, the silk is severe, and the single silk has no elasticity and no tensile force.

6. Life life

High -quality Shading nets have been used for more than 3 years under natural climatic conditions (excluding membrane, sulfur corrosion and polymeter areas).

The inferior Shading net is less than 1 year under natural climate conditions.

7. Economy

The high -quality Shading net is generally calculated according to the Square number, and the surface price is high.However, due to the light weight of the mesh, the actual length is accurate, the area is large, and the service life is long. It is much more affordable to calculate according to the service life of peace.

The inferior Shading net is generally calculated according to weight, and the surface price is low.However, due to the weight of the webbage, the actual length is insufficient, the use area is small, the service life is short, the labor cost is high, the cost of the shed is high, and it is not affordable.

What does it mean to control the Fertilizer?

Controlling Fertilizer is a high -form form of slow -release Fertilizer. It mainly controls the release of nutrients through envelope technology to achieve the purpose of safe, long -term and efficient. It is the main direction of modern Fertilizer development. It is suitable for mechanized production. The broadcast needs to wait.

What are the characteristics of controlling Fertilizer

The first is to increase the utilization rate of chemical Fertilizers and reduce the amount of Fertilizer.

Because controlling and release of Fertilizer has a slow -release effect, it can reduce the gaseous and leaching loss of chemical Fertilizers, thereby improving the efficiency of the utilization of chemical Fertilizers.The test data shows that the controlling Fertilizer can increase the utilization rate of Fertilizers from about 35%, and the loss rate of nitrogen fertilizer is significantly reduced, which can save 30%-50%of nitrogen fertilizer.

The second is to reduce the number of Fertilizers and save labor.

Due to the lack of labor in rural areas or due to lack of water and inadequate water supply, crop fertilization is becoming increasingly simplified, and one -time fertilization of crops is quite common.At present, the one -time Fertilizer sold on the market is basically fast -acting high -nitrogen -type Compound fertilizer, and there is a risk of long -term seedling or later Fertilizer.The release of the release of Fertilizer can be scheduled to design the release mode of the Fertilizer in the growth season of the crop, so that the law of the nutrient release of the Fertilizer is consistent with the absorption of crop nutrition, and one -time fertilization meets the needs of the entire growth season of crops.

Controlling Fertilizer can also be used for cultivation of farming and soil -free cultivation. seeds and Fertilizers can be sowed, and irrigation is sufficient, which is very convenient.Many soil -free cultivation of irrigation nutrient solution.Sometimes the nutrient solution is not well matched, and the Miao Changshi is not good. It solves this problem with controlling Fertilizer.

The third is to reduce crop disease and improve the quality of agricultural products.

Crop disease and product quality are related to the amount of nitrogen fertilizer. Applying controlling and release Fertilizer can prevent crops from absorbing excessive absorption of nitrogen, thereby suppressing diseases and improving quality.

How to use release Fertilizer

When using, Fertilizer isolates and covers soil after application. For example, when planting corn and cotton crops, the distance between the seeds and Fertilizers is about 7-10 cm, the depth of fertilization and sowing is about 10 cm.

Note:

1. When the use of controlling Fertilizer is used, the amount can generally be applied according to 80%of the Fertilizer in previous years. At the same time, it is necessary to increase or decrease appropriately according to different crops, target yield, and soil conditions.

2. Not suitable for the use of drought land and sandy land.In the absence of moisture, nutrients cannot be effectively released, which may cause crops to affect the growth due to the inability to absorb effective nutrients and cause crop production to reduce production.

The difference between control release Fertilizer and slow release Fertilizer

Control and release Fertilizer: It mainly controls the release of nutrients by performing envelope on the Fertilizer. The Fertilizer has a longer Fertilizer and more nutrients, but it is only suitable for use in the peak of the crop. , Roots and mountain spray irrigation.

Smooth -release Fertilizer: The Fertilizer effect is relatively slow, and its composition is relatively single. The main elements contained in are nitrogen elements, and the water solution itself is relatively low.

The difference between controlling and Compound fertilizer

Control and release Fertilizer: It mainly controls the release of nutrients through envelope technology. The Fertilizer effect is longer, and the nutrients containing are relatively comprehensive, but it is only suitable for crops to use it at the peak of the need for Fertilizer. Roots, mountain spray irrigation, etc.

Compound fertilizer: It mainly contains nitrogen, phosphorus, potassium and other elements. It is generally appropriate to fertilize (gap, acupuncture, etc.) when fertilizing, and it is usually used as base Fertilizer.

1. What kind of sunshade mesh and web needle is more solid

The flat needle Shading net has a closer structure, smaller acupuncture pitch, stronger and durable, longer service life, good toughness, not easy to break, and strong wear resistance.The network needle is resistant to corrosion, which can be used in humidity, and at the same time, ventilation is better.Therefore, the specific choice of the Shading net should be selected according to the environment and requirements.

2. Which sunscreen mesh and oblique needle is durable

The durability of the oblique needle.The Shading net with the same material and needle is better to choose a diagonal needle.Because the oblique needle is more firmly woven, it is not easy to occur during use and damage.Relatively speaking, the durability of the flat needle is not strong, so it is recommended to choose the oblique needle when choosing a Shading net.The oblique needle's Shading net has a good effect on disaster relief and income. During the use process, it must be straightened, tightened, and flattened. There must be no low places. Otherwise, it is prone to stagnant water falls on rainy days, causing the net to be damaged.

3. precautions for Shopping.com

1. When buying a Shading net, many people are very easy to buy a net with a high shielding rate, which is mistaken for the high shielding rate.However, too high shielding rate causes weak light in the shed, reduced photosynthesis of crops, weak stems, and long -term problems, which reduces the production of crops.So try to choose the Shading rate as low as possible when choosing a Shading net.

2. When buying a Shading net, try to choose a guarantee product with big manufacturers and brands, and determine the use of products that have been used for more than 5 years on the greenhouse.

3. The thermal contraction characteristics of the shade net are easily ignored. The most contracted in the first year, about 5%, and gradually become small.With its contraction, the shielding rate will increase.Therefore, it is necessary to consider its thermal contraction characteristics when using a card slot.

1. What does it mean?

The Shading net is divided into scriptures and weft, and the edited Shading net is divided into several needles according to the different weaving needle distance.How many shots of the Shading net refer to the number of pins in each inch. The more the number of pins, the dense the network.Depending on the number of needles, the Shading net can be divided into one shot Shading net, two -needle Shading nets, three -needle Shading nets, and more pins.Of course, due to the difference in the number of Shading mesh pins, the fields and environments they are used will be different.

1. One needle Shading net

One shot Shading net is a mesh composed of a weir silk within a one -inch distance.Its weight is about 5 to 10 grams per Square meter.It is mainly used on the outer packaging on project products, replacing the traditional hemp cloth packaging to prevent humidity, rust removal and anti -rust.

2. Two shots of Shading nets

Two shirts shade nets are composed of two weirons within a one -inch range.Its main role is to strengthen the greening measures of construction companies in dustproof work.

3. Three -needle Shading net

The three -shirt Shading net is a net composed of three weft silk within one inch.It is mainly used in agriculture.The function is to provide coverage for agricultural planting and breeding projects.

4. Four -needle Shading net

The four -needle Shading net is a net composed of four weft silk within one inch.This network is a balcony Shading net. Its main function is for the use of Sun protection and garden sunscreen for Shading.

5. Six -needle Shading net

The six -needle Shading net is a net composed of six weft silk within one inch.This network is generally only used for the basic accessories and Shading of the fence facilities.

6. Eight -needle Shading net

The eight -needle Shading net is a net composed of eight weft silk within one inch.This network is limited to the use of engineering protection and avoid damage caused by high -altitude falls.

7. Nine -needle Shading net

The nine -needle Shading net is a net composed of nine weft silk within one inch.This net is the same as the eight -needle Shading net, but the density is different, and the performance is slightly stronger than the eight -needle Shading net.

8. Ten needle Shading nets

The ten -shot Shading net refers to a net composed of ten weft silk within one inch.The density of this network is very high, the green ten -pin Shading net can be used as a camouflage network, which can prevent drones and prevent sailing.

2. The difference between 8 stitches and 12 stitches of Shading nets

The difference between 8 pins and 12 stitches on Shading nets is that the density is different, so the Shading rate is also different.Generally speaking, 8 stitches will be thinner, and 12 needles will be dense.The more the ungrate mesh, the dense the mesh eyes, the better the Shading effect.Compared with 12 stitches, the Shading effect of 12 stitches is better.

2 needle Shading net: sunshade 40%-80%.

3 needle Shading net: sunshade 50%-85%.

4 needle Shading net: Shading rate 60%-90%.

6 needle Shading net: Shading rate 80%-98%.

6 needle round wire Shading net: 50%-70%of the Shading rate.

9 needle Shading net: Shading rate 70%-80%.

12 -needle Shading net: The Shading rate is 95%.

The commonly used Shading nets are 6 stitches and 12 stitches. The quality of 6 stitches is relatively poor. The rainproof effect is not good. 12 stitches can effectively prevent rain and prevent rain.

For Xiguang flowers, when using a Shading net, most of them can be used with two or three stitches.The demand for light is not highflowers, Most of them can be used with a four -needle.
