The poor air permeability of the film leads to the poor growth of vegetables, how can we improve the

This problem is most common in the suburbs of the city and in some large shantytowns planted in vegetable gardens, continuous cropping, intercropping, oxygen also has a certain demand, such as eggplant, the soil layer is too compact, when the oxygen is less than 6%, its roots are difficult to breathe, and there is no way to grow normally in the soil. Each vegetable has a different need for oxygen, and the more severe the lack of oxygen, the greater the impact on the vegetable.

High planting density, needles, excessive use of chemical fertilizers, serious drug residues, reduction of organic fertilizers, and lack of deep ploughing and subsoiling of the land are the main reasons for poor soil permeability, and it is an important reason for the development of crop roots. Because the soil permeability will directly affect the quality and poor growth of vegetables grown by growers, there are many reasons. Poor soil permeability is one of the main reasons.

Soil compaction, salinization, etc. will cause poor air permeability, the main channel, this is because people's lifestyle from the past relying solely on food life, to a variety of food life transition, and vegetables have become the embodiment of people's healthy lifestyle. In fact, we can clearly see that whether it is the enthusiasm of vegetable farmers to plant, it will affect the growth of the root system. Everything needs a good root system to grow.

How to improve soil permeability can be analyzed from the following aspects. The reason why vegetables do not grow well is due to the structure of the soil, and it is not a fertility problem, but a case of air permeability. And the problem of air permeability comes from digging deep into the soil.

Rural people often say that the land is divided into raw land and cooked land, and raw land refers to the infrequent planting of crops, and the soil quality and soil layer are relatively loose, so it is better to grow crops. Cooked land is often planted, and if you don't pay attention to crop rotation, the soil will be compacted and poor air permeability. Now on the vegetable planting ground, the texture of the soil can also be seen to a certain extent, that is, it is relatively sticky.

In other words, this problem can also change the yield of sticky vegetables. Growers often have poor root development due to soil compaction and poor air permeability, which in turn leads to premature decay and yield reduction of crops.

The first point is to pay attention to the whole greenhouse, the temperature should be mastered, the second point humidity should be mastered in order to have an effect, and the third point should be mastered the most basic process of the soil.

The soil should be fertilized more, the soil should be watered more, and some sandy soil should be put when planting so that the air permeability will be improved.

You can poke a few holes in the soil close to the roots, so that the air flow of the soil is good.

You can loosen the soil from time to time, give enough ventilation to the growing space, and poke a few small holes in the membrane cloth that wraps the vegetables, so as to effectively prevent the planted things from growing well.

The soil should be turned more so that the soil will not be very firm and the vegetables will grow well, so that the vegetables that grow are chewy.

Reduce the use of chemical fertilizers. Mainly organic fertilizer. Regular loosening of the soil. If necessary, the soil needs to be replaced.

1.Increase the application of organic fertilizer to increase the content of organic matter in the soil.

2.Reasonable watering to reduce the damaging effect of watering on the soil.

Cultivating a strong root system is a necessary means to improve the stress resistance of vegetables and increase yield. The key to determining the robustness and stress resistance of vegetable roots is the air permeability of the soil. The soil has strong air permeability, sufficient oxygen, and sufficient root respiration, which can produce more energy, enhance the absorption capacity of the root system, improve the stress resistance of vegetables, and then increase the yield.

Increasing the application of organic fertilizer and returning straw to the field to improve the content of organic matter in the soil are the fundamental measures to improve the soil permeability. Soil organic matter is an indispensable component for the formation of soil aggregate structure. When the organic matter content is high, the soil is loose, and the soil with good air permeability is called "sponge field", and the crop yield is the highest.

Data show that the soil content of organic matter in most parts of China is about 1%, which is below the 2% limit suitable for vegetable growth. Therefore, it is necessary to increase the application of organic fertilizer and straw returning to the field to improve the soil and improve the soil permeability.

Reasonable irrigation, large flood irrigation to drip irrigation or small water irrigation, the traditional furrow irrigation, furrow irrigation, etc., have the effect of soil erosion and compaction, and the aggregate structure of the soil will be destroyed, which is not conducive to improving soil water and fertilizer retention. After the vegetables in Chixiang's shed grow, they are covered with mulch, and it is difficult to loosen the soil in the cultivation, and the soil compaction cannot be broken. Drip irrigation is different from flood irrigation in that it can slowly infiltrate the soil and have little effect on the soil.

In areas such as Qingzhou, Shandong Province, where drip irrigation has been promoted for many years, vegetable farmers generally report that the soil in the shed using drip irrigation is looser and more breathable.

The application of biological fertilizer to improve microbial activity leads to the accumulation of harmful microorganisms in the soil due to long-term continuous cropping, and the beneficial microorganisms will be reduced, which is prone to root diseases and causes vegetables to grow normally. The accumulation of harmful microorganisms also has a great impact on soil properties. Many beneficial microorganisms themselves have the effect of improving soil and improving soil permeability, which can loosen the soil on the one hand while reproducing, and on the other hand, it will produce some substances that promote the growth of the root system while decomposing the nutrients fixed in the soil, which is very beneficial to the growth of the root system.

Therefore, it is necessary to increase the number of beneficial bacteria in the soil by applying biological fertilizer, so that the beneficial microorganisms in the soil occupy the advantage.

Increasing the content of organic matter in soil is a fundamental measure to improve soil air permeability. Soil organic matter is an indispensable component of the main body of soil aggregate structure. If the organic matter content is high, the soil will be loose, and the soil with good air permeability is called "sponge field", and the crop yield is the highest.

Data show that the organic matter content of soil in most parts of China is about 1%, which is below the 2% limit suitable for vegetable growth. Therefore, it is necessary to increase the application of organic fertilizer and straw returning to the field to improve the soil and improve the soil permeability and resistance to ants.
