1. A few shots of Shading nets are best

For the greenhouses that plant vegetables, not only should it be clever in summer, but also shade and cover the shade net.The shade net is divided into two, three stitches, four stitches, six needles and other species according to the fine degree of density or light transmission.The Shading net is too sparse, the Shading rate is not high, and the cooling effect is poor.The Shading net is too dense, the light is too small, and the vegetables are easy to grow.

After a summer practice, the greenhouse Shading net generally uses a three -needle Shading net, and two -needle Shading nets can also be used.Essence

At the same time, when the temperature is high in summer, the cooling effect can be enhanced by covering two layers of sunshade nets. The first layer is fixed, relatively sparse, and can be used with two stitches.The other layer is activity. You can use three stitches to open it when you need it, and put it away when you do not need it.Generally, the temperature of the temperature will be on the event at 10 am to 11 am, and the Shading net on the activity will be opened. When the temperature starts from 3 to 4 pm, it will be put away when the temperature starts to steadily decrease. This can control the temperature to a certain extent.Not long.

Second, the more the number of ungathetic net needles, the better, the better

How many pins of the Shading net represent the number of pins in each inch. The more the number of stitches represents the densely the eyes, the better the Shading effect, but the too large number of needles will also cause the shade net to be too heavy, which is not conducive to ventilation and breathable.Therefore, the number of needles for the choice of Shading nets needs to be determined according to the actual usage and needs.To achieve a good Shading effect, it will not affect the circulation of indoor air.

The main function of the Shading net is to block the sun and prevent plants from being sunburned or sunburned.If you want plants to better photosynthesis, you can choose a low -number of pins (such as 3 stitches or 4 stitches) may be more suitable.If you want to sunscreen better, you can choose a high -number of pins (such as 6 or 8 stitches).

Emerging agricultural machinery equipment, replacing traditional manual operations, has the characteristics of high efficiency and convenient carriers to get the love of farmers' brothers!

definition

The seeder refers to the planting machine with crops and seeds as the object. The seeder has the characteristics of uniform seeding, consistent depth, stable lines, good soil covering, saving seeds, and high work efficiency.

Pay attention to the main points

Pay attention to the following points to master the following points:

Before entering the field, clean up the debris in the seed box and the entanglement and soil on the ditch to ensure a good condition. The transmission and rotation parts of the tractor and the seeder will be injected with lubricating oil according to the requirements of the instructions, especially in particular, especiallyBefore each job, pay attention to the lubrication and tension of the transmission chain, and the tightening of the bolt on the seeder;

The rack cannot be tilted. After the seeding machine is connected to the tractor, it must not be tilted. When working, the front and back of the rack should be in a horizontal state;

To do a good job of various adjustments, in accordance with the provisions and agronomy requirements of the instruction manual, the seeding amount, the spacing of the ditch, and the depth adjustment of the ditch to the soil suppression wheels are appropriate;

Pay attention to adding the seeds and add the seeds of the seed box to achieve no small, , and miscellaneous to ensure the effectiveness of the seeds; secondly, the amount of seed boxes should be added to the entrance to the breeding box to ensure the Smooth seeds smoothing the Smooth breeding boxesItems

In order to ensure the sowing quality of the seeder, before the large -scale sowing, you must insist on the trial broadcast for 20 meters to observe the work of the seeder.Ask agricultural technicians, local farmers and other test consultations to confirm the local agronomy requirements, and then plant large -scale seeding;

Pay attention to the uniform speed line, and the agricultural machine handles choose the operation to walk the route. It should be convenient for the addition and mechanical entry and exit. When sowing, pay attention to the straight line forward.

In order to prevent the ditch from blocking, the lifting of the seeding machine should be operated during the travel, and the seeding machine should be lifted when retreating or turning;

Predse the ground first, first sow the ground to avoid rolling the ground, causing deep broadcasts; regular observation, often observing the work conditions of the gaunting device, ditch, coverage, and transmission mechanism during sowing., Covering grass and seeds are not strictly covered, and timely eliminate it.

Adjusting, repairing, lubricating or cleaning up grass, etc., must be carried out after parking;

When the protection of the machine, when the seeding machine is working, it is strictly forbidden to retreat or turn sharply.

Pay attention to the seed box, the seeds in the seed box during operation must not be less than 1/5 of the seed box volume;

When transporting or transferring the block, there must be no seeds in the seed box, let alone other heavy objects.

history

The first seeder was made in Greece in 1636.In 1830, the Russians installed the seedlings on the livestock plow to make a plow broadcasting machine.After 1860, Britain, the United States and other countries began to produce large amounts of animal grain sowers after 1860.After the 20th century, traction and suspension grain seeders appeared one after another, as well as the seedlings using forceful seedlings.In 1958, the first centrifugal seeder appeared in Norway, and various precision seeders gradually developed after the 1950s.

The seeder was introduced in the 20th century, and in the 1960s, it was successfully developed a variety of models such as the suspension grain seeding device, centrifugal seeder, universal rack seeder, and air -suction seeder.Formulator.By the 1970s, two series of sowing plowing machines and grain joint seeding device had been formed and put into production.Various broadcasting machines and acupoints for grains, farming crops, pastures, and vegetables have been promoted and used.At the same time, a variety of precision seeders were successfully developed.

maintenance method

After the seeding season is over, the dust on the seeds is completely cleaned, and the seeds and Fertilizers in the seed box are cleaned.The friction parts and transmission devices of the seeding machine are cleaned, and lubricate, such as the transmission chain, and apply the rust -proof agent after drying.Check the tightness of the connector. If there is a loose, it should be tightened in time.

The exterior and seeding shaft of the gear transmission device of the seeder should be coated to lubricate oil.The springs should be adjusted to a free state of freedom.The sowing machine should be placed in a dry and ventilated warehouse. If it is kept in open -air, the wooden seed box must be covered, and the seeding machine should be matched in two wheels.The frame should also be padded to prevent deformation.The preparation, parts and tools should be stored in the library. After the seeding machine is stored for a long time, it should be maintained early before sowing in the next season.

The metal transmission Tube of the seeder should be removed. Do not deform in the indoor control. Relax the telescopic springs of the ditch.place.The disc truncapus must be decomposed. After cleaning the diesel, reassemble and get the oil. The surface of the inside and outside of the disc is coated with waste oil. It is placed in a dry and covered room.Get up with a wooden board.

If the seedlings or ditch of the seeder, if it is blocked, clay, grass, and seed coverage, it should be excluded in time.Adjusting, repairing, lubricating, or cleaning the seedworm entanglement, etc., must be carried out after parking; when the seeder work, it is strictly forbidden to retreat or turn sharply.The seeds inside should not be less than 1/5 of the seed box volume; when transporting or transferring the blocks, there must be no seeds in the seed box, let alone other heavy objects.The precautions for the use of the seeder are not limited to the above points. Farmers need to be continuously accumulated by reading product manuals and farming practice.

Life

Sowing device is a very common agricultural machinery equipment used in rural areas. As long as it is a equipment, it cannot avoid loss during the use process. So how can we minimize this loss? This requires us to use it in daily use.Do a series of maintenance work before and after.In this way, it can ensure that the equipment can be used normally and allows the service life of the equipment.

Before use: If it is a product of the previous year, you need to check the transmission parts of the gear of the seeder, check whether the parts can operate normally, can be applied to lubricating oil for maintenance, and the spring device corresponding to each component needs to be checked.If there is a loose and more slippery, the user uses the newly purchased products without these operations. It only needs to be assembled;

When used: installation and use according to the technical requirements of the manufacturer, the Fertilizer box should not be loaded. Do not operate vigorously when sowing. It is forbidden to pull down or turn sharply.

After use: thoroughly clean up the Fertilizer box and place the seeder in a ventilated and dry warehouse. If the open -air is kept, the seeder should be covered with operations. To prevent parts from damage, disassembly and keeping can be performed.

A device that allows user income, you can rely on the quality of the equipment itself, and add reasonable operation methods and maintenance methods, so as to ensure the product's maximum effect and increase the service life of the product.

[Vegetable seeds Type] How to classify vegetable seeds for vegetable seeds

Vegetable seed classification

Conventional seed

The conventional vegetable species (OP) is the seeds that the vegetables grow through natural laws.At present, there are many problems with conventional breeding of vegetables.

First, there are many varieties.Under the nickname of science and technology is the first productive forces and science and technology policies, scientific research institutions, experts and scholars engaged in agricultural breeding work have sprung up, and new achievements and new varieties have continued to emerge.The problem that follows is that one is that there are many varieties, the characteristics of the characteristics are small, and the difficulty of miscellaneousness during breeding has increased, and the authenticity and purity of the variety are difficult to guarantee.There will be Mr. Nan Guo's fishmarks, which will push some varieties and systems that have poor characteristics, poor adaptability, or no production value at all, and mislead and interfere with normal seed production and operation order.Therefore, the purchase of vegetable seeds should be based on a good reputation.Buy regular seeds.

Second, the seeds are similar to non -seed, and they are hidden in production.The first is similar appearance.The difference between conventional seeds and seeds itself is not very different.Therefore, it is difficult to identify in the choice.This causes the consequences of lack of understanding of seeds and damage production.Especially the base vegetable species are particularly unsatisfactory.As a result, the following introduces the identification and purchase method of conventional vegetable seeds.

Hybrid seed

Vegetable hybrid seeds (F1 general hybridization is a generation of hybridization) is to pollinate it by using different characteristics of plants (parent, mother -in -law) to change the variety characteristics.

There are parents in the field of hybridization, and the appearance performance of sub -grain forms is also very different from normal grain cotton oil (such as hybrid rice seeds, more exposure of stigma, not full of hybrid rapeseed seeds, etc., as well as hybrid fruit corn seedsLight quality and dry.

Vegetable hybridization has two inherited differences in the inheritance. At the same time, their excellent traits and complementary vegetable varieties are used for hybridization. The first generation of hybrids with hybrid advantages are used for production. This is a hybrid vegetable seed.The advantages of hybrid vegetable seeds are a common phenomenon of the biological world. Using the advantages of hybrids to improve crop yield and quality is one of the main achievements of modern agricultural science.

However, due to the rapid development of vegetable hybrid varieties after the scientific call, the types of vegetable hybridization are not lower than conventional varieties.Under normal circumstances, hybrid vegetable seeds have disease resistance and can quickly adapt to the local climate environment.This is also one of the purpose of vegetable seed hybridization.But the ultimate goal is that we hope that hybridization can bring greater economic benefits.

At present, the hybridization of vegetable seeds is becoming more and more common, and it has studied and breeding tens of millions of varieties.While buying vegetables seeds, we must also pay attention to the adaptability of such varieties to the local climate and the consumption ability of the local market.You can't buy it blindly.At present, there are many kinds of hybrid vegetables on the market, and many of them belong to fake hybrid vegetable seeds.And one time is used to disturb the market.So try to buy regular companies when buying, and it can be easily ordered through mobile phones and computer online, and directly shipped the country.In addition, you can also buy it directly at the agricultural Sciences at all Levels.It is also convenient to buy online.

Because the hybrid vegetable seeds have a genetic factors that have miscellaneous, they cannot be used in the next year after the vegetables are harvested.However, the hybrid vegetable seeds are more advantageous in terms of yield and disease resistance than ordinary conventional seeds.Therefore, most of the professional vegetable growers are using hybrid vegetable seeds.

Vegetable seed identification purchase

Onion seeds, leek seeds: The new seeds of the year must be greatly reduced.The method of identifying the old and new seeds is: the surface of the new seeds has wrinkles, the dark side is clear, and the luster is shiny. There is a clear little white point on the umbilical umbilicus.seeds that store for more than 1 year, the surface is lost, a layer of white frost appears, and the umbilical umbilicus has changed from white to yellow. Such seed germination rates, low growth potential, should not be used.

Tomato seed: Generally, it can be saved for 3 to 4 years, and it does not exceed 4 years, otherwise the germination rate will be reduced.The method of identifying the old and new seeds is: there are many small hair on the new seeds, and the tomato flavor. The old seeds have less hairs or fall off, and the smell becomes lighter.

Chili seed: It cannot be more than 3 years.New seeds are spicy, and the seeds are golden brown.The germination rate of new seeds is about 90%, the bud rate of 2 years is about 80%, and the bud rate of 3 years will be reduced to less than 50%.

Celery seeds: It can be stored for 5 years, and the new seeds that year are unavailable. It must be used for 1 year.

Coriander: It must be stored for 1 year, but it should not exceed 3 years.New coriander seeds are strong, and old seeds are fade.

Eggplant seed: The storage time can be slightly longer, and the seeds can be used within 5 years.The outer Skin of the new seeds is bright, milky, and the surface of the seeds is dark red and no light.

Cabbage, radish, cabbage seeds: The general storage life is 3 to 4 years, and the germination rate of more than 4 years has decreased significantly.The surface of the new seeds is Smooth, the surface of the seeds is dark, and after the seeds are crushed with nails, the new seeds will not be broken, the seeds are fragile, and the seeds are easy to fall off.

Cucumber seed:It can generally save 3 to 4 years.The surface of fresh Cucumber seeds is white or milky white, Smooth surface, and the burrs at the tip of the seeds are pointed. Matsters appear on the surface of the seeds, losing their luster, and the burrs at the tip of the seeds become blunt.

1. The benefits of covering vegetable cultivation

1. Prevent the impact of heavy rain

After covering the shade net, the heavy rain can be turned into small rain to prevent the direct impact of rainwater on seeds, seedlings, plants and soil. Therefore, the coverage of the shade net can play a role in improving the seedling rate, protecting the seedlings and preventing soil plate knots, avoiding heavy rain pairs.The mechanical damage caused by plants and promote the growth of plants, which is the main reason why summer and autumn covered with cultivation leafy dishes.

2. Prevent the radiation of strong light

After covering the shade net, it can prevent strong light radiation, which can greatly reduce the rate of sowing or transplanting the seedlings or transplants in the summer and autumn high temperature and strong light season.At the same time, after covering the shade net, it is also conducive to the photosynthesis of vegetables and improves yield and quality.

3. Reduce temperature

In the southern region, due to the effect of high temperature in summer, it is extremely unfavorable to the growth and development of plants. After covering the Shading net, it can reduce the temperature in the network, create a more suitable temperature environment, avoid the adverse effects of high temperature on plant crops, and promote the promotionThe growth and development of plants are conducive to the potential for production.

4. Reduce evaporation, moisturizing and drought -proof

The covering net covering cultivation vegetables can not only greatly reduce Solar radiation, but also reduce the evaporation of soil moisture. It can reduce the amount of water evaporation by about 60 % -70 % than the open field cultivation, thereby reducing the number of watering and irrigation, increasing the high temperature and drought seasonThe moisturizing ability of the soil is conducive to plant growth.

5. Insulation and cold, anti -frost

In addition to the cultivation of summer anti -thermal and rainfall coverage, the Shading net can also be used for early spring prevention and night cream, late autumn prevention early frost, autumn and winter anti -freezing damage and other coverage cultivation.It is used when the temperature is low in winter. When it encounters severe frost, it can delay the occurrence of frozen merging process, reduce frost damage, and make the crops safely overwinter.

6. Reduce disease

After covering the Shading net, it can significantly reduce the occurrence of virus disease, especially the aphid avoidance and anti -virus disease covering the silver -gray shade net. Generally, its anti -prevention efficiency can reach more than 85 %.

7. Improve the survival rate of seedlings and the quality of seedlings

The high temperature and strong light in the south in the south make seedlings more difficult, the survival rate of seedlings is low, and the seedlings of seedlings are poor. In the summer, the use of Shading nets is covered with cultivation seedlings, which can improve the quality and survival rate of seedlings.20 % -80 %, comprehensive indicators such as plant height, development, leaf number, stem thickness, and single plant weight can be increased by 30 % -50 %.

8. increase output and relieve the off -season

In the southern area, summer and autumn are affected by tropical cyclone, high temperature, high humidity, high temperature drought, and strong light. It is extremely unfavorable to plant growth and development. It is difficult to produce and decline in production. It is the main reason for the summer and autumn season.The use of Shading coverage can effectively solve the problem. Generally, it can increase production by 20 % -50 % or more, and the income increase of about 30 % -100 %.Therefore, the coverage of the shade net can increase the variety of market color, improve production and quality, and alleviate the tension of production and supply of off -season production and supply have important practical significance.

9. Easy to use, save labor, reduce production costs

Compared with the traditional coverage materials, the Shading net covers the advantages of high strength, aging resistance, light texture, convenient use of transportation, low labor strength, etc., and also has provincial labor, low energy consumption, low cost, high yield, high -efficiency, high -efficiency, efficient, high -efficiency, and efficient efficiency.Features.

2. How good is the Shading rate of the vegetable Shading net?

When buying a Shading net, we must first clarify how high the Shading rate of your shed.Under the direct sunlight in summer, the strength of the light can reach 60,000 to 100,000 Lax. For vegetables, the light saturation point of most vegetables is 3-60,000 tolex.Lax, 55,000 cucumbers, and 70,000 Lax's light saturation points of tomatoes.Excessive light will affect the optical fitting effect of vegetables, leading to the absorption of carbon dioxide, excessive breathing strength, etc., and the phenomenon of optical "lunch break" in natural conditions is created.Therefore, the use of a suitable Shading metering net can not only reduce the temperature in the shed around noon, but also improve the optical efficiency of vegetables, and get two birds with one stone.

The black Shading metering rate is high, which can reach 70%. Using a black sunshade net, the light strength does not meet the normal growth needs of tomatoes, which can easily cause tomato to grow long and lack of photosynthetic products.Most of the silver -gray Shading mesh is 40%~ 45%, and the light transmission rate is 40,000 to 50,000 Lax, which can meet the normal growth needs of tomatoes.So tomatoes are best covered with silver -gray Shading nets.You can choose a Shading net with a high light saturation point with peppers. For example, the shielding rate is 50%-70%to ensure that the light in the shed is about 30,000 Lax;For the type of vegetables, you should choose a Shading net with a low shielding rate, such as 35%-50%of the shielding rate, and ensure that the light in the shed is 50,000 Lax.
