Vegetable greenhouse construction management can not be saved

In the construction and management of vegetable greenhouses, some vegetable farmers have plans to save time. When the shed is built, the top wall is directly used to build the back wall. Some organic fertilizers are used when they are not sufficiently cooked. These incorrect practices will affect the vegetables in the later period. Normal production will seriously cause the loss of crops and die seedlings. Therefore, everyone must not be able to save time and effort.

First, when a new greenhouse is built, it cannot be directly used to divert the surface plough layer soil to the back wall soil.

At the beginning of the construction of the greenhouse, it is easy to have a problem. The engineering team that undertook the construction of the greenhouse often directly digs out the original cultivable soil for the purpose of labor saving and uses it as a back wall soil. As a result, the soil in the greenhouse was all raw soil without growing plants.

The plough layer soil is formed through years of plant growth and tillage management. The content of available N, P, K, and trace elements is relatively high. The species and amount of microorganisms in the soil are large, and the water permeability is good, which is more suitable for plant growth. The original raw material in the deep soil is on the contrary, where the plants grow, and what they want to eat does not coexist. The permeability of water and gas is poor, and the amount of fertilizer applied to the soil is too small for microorganisms to be transformed into easy time. The form absorbed by the roots eventually leads to a series of problems such as slow growth of plants, yellowing of leaves due to poor living conditions after planting of vegetables, and difficulty in growing new roots. Therefore, when building a new vegetable greenhouse, we must supervise the construction team and move the tops of the cultivated land to the side of the greenhouse. After the construction of the greenhouse is completed, these ripening soils will be moved back into the greenhouse.

Second, the map does not advance the farmyard fertilizer

In fact, many people are aware of the necessity of using adequately decomposed farmyard fertilizers, but many vegetable farmers are not willing to ferment the farmyard fertilizers first. There are two reasons for this, one of which is that it is too much for oneself to ferment and decompose, and one is fortunate and improvising.

There are two ways to solve this problem. One is to directly purchase commodity organic fertilizer, and the other is to find a more convenient method of fermentation and maturity. Farmers often prefer to spend money on chemical fertilizers, but they are reluctant to buy organic fertilizers for two reasons. One is not knowing what kind of organic fertilizer to buy, and the other is that the cost of buying commodity organic fertilizer is too high.

At present, there are many types of organic fertilizers, but the quality is very different. How to buy the right organic fertilizers is really learned. First of all, try to look at the brand as much as possible. The reputation is good and the quality will be reliable. Then we must look at the nature of the fertilizer, which kind of organic matter, such as seaweed, chicken manure, or organic matter plus biological bacteria, especially chicken manure, must be branded and properly packaged. Before the purchase, you can also smell the smell. If there is odor, it means that the fermentation is not good. If there is a pungent odor, some chemicals may have been added. None of these can be used. Carefully use your eyes, grab a hand, and look at its moisture content, particle uniformity and so on. It should be noted that the truly industrialized production of high-quality organic fertilizers with less impurities and concentrated nutrients does not necessarily require the use of chicken manure, which requires five or six cubic meters per mu, which should be applied as appropriate according to the product description and the period of use. However, the application cost per unit area is not high.

As for how to make it easier to ferment, first we must choose the season of warm and rainy weather in spring and autumn, and it is too inconvenient for winter to be too cold and summer to be rainy. Then, first dry the chicken droppings for several days, then add crushed straw, biological bacteria and water in proportion, or add superphosphate or urea, or layer or mix, and pile them together. It is best to cover them with mud. Plastic film, because the plastic film is not conducive to ventilation and can easily lead to excessive temperature inside the heap. After these farmhouses have lost their odor and loose their texture, it means that they have become successful. The key to saving here is the addition of biofermentation bacteria, which is equivalent to the daily use of yeast powder in the production of wolfberry hair. The speed and effectiveness of farmyard manure fermentation will be faster and better. It should be noted that sun dried chicken dung does not mean that it has been fermented and cooked.
