People are increasingly demanding vegetables, and sometimes anti-season vegetables also want to eat, so now the technology of greenhouse cultivation is very popular. Relatively speaking, the crops grown in greenhouses will have a greater demand for fertilizers. Many growers have the habit of abusing fertilizers. It is always believed that more crops will be used and crops will grow better. In the long run, the soil is prone to problems. In fact, most of the fertilizer is not absorbed by the crops, but is lost, or remains in the soil. These chemical components remain in the soil, and it is easy to accumulate salt. Sometimes the surface of the soil has some white matter. When it is more serious, it may appear cyan, or red. This is the excess of elements in the soil. However, this kind of soil does not mean that there is no need to apply fertilizer. These elements remain in the soil and are fixed by the soil. They cannot be absorbed by the crops. The crops are not growing well and will affect the roots of the crops because the salt concentration in the soil is too high, especially After watering, the crop appears to be soaked in salt water. Moreover, it is easy to reduce soil vigor and increase pests and diseases. The method of identifying whether the soil accumulates salt is also very simple. If the water is poured and the soil seeps well, then there is no salt accumulation in the soil. If the water is difficult to permeate and the land is idle for a long time, It is easy to appear some white crystals, then this salt is more serious. So how to solve and improve the problem of salt accumulation in the land? I. Irrigation Generally, it is selected when the greenhouse is idle. If it is watered, it can not only improve the problem of salt accumulation, but also kill some bacteria in the soil. Because a lot of water is poured, the oxygen in the soil is taken. Out, some pests will easily die due to lack of oxygen. If it is watered, it is about five to seven centimeters deep. Wait until it is soaked for a few days, then drain the water. This will have a good effect if it is repeated several times. If it is more convenient to touch the rain and rain, remove the film on the greenhouse directly. Second, rational use of fertilizer The reason for this problem is because of the abuse of fertilizer, so we must pay attention to the rational use of fertilizer. In particular, some fertilizers containing chlorine, if used too much, are prone to such a situation. Appropriate use of organic fertilizers is very helpful in improving the soil and can reduce the problem of salt damage. Third, deep When the shed is idle, the land can be deep turned over, and the surface soil is more salty. You can turn it to the bottom, and at least turn it to 25cm. Nowadays, the land of many greenhouses will have the problem of salt accumulation. It is necessary to pay attention to it and find ways to improve it, otherwise it will affect the growth of crops and thus reduce the harvest. The growers can try these three methods and it is very helpful to improve the soil.
