How to improve the arch shed soil

  The causes of soil deterioration are mostly caused by unreasonable fertilization by vegetable farmers. In the past few years, vegetable farmers prefer to apply compound fertilizer. In recent years, a large number of water-soluble fertilizers have been applied. Over time, the soil salt has accumulated more and more, and more and more knots, secondary salts. The staining is serious, and the red and green moss appears on the soil surface. As a result, the vegetables grow poorly, like the "yellow leaves" (leaf yellowing, concave, and brittle) commonly found on watermelons; the "flower face" of pepper leaves, many vegetable farmers mistakenly believe that The occurrence of mosaic virus is not a viral disease, but a physiological disease that occurs due to soil problems. There is also a problem of peppers that cause headaches in vegetable farmers (the soil is green moss, and the aboveground symptoms of pepper plants are not obvious, but close The stalks on the surface become thinner and then gradually wilted and die. These problems are caused by soil deterioration. Therefore, in order to ensure the improvement of vegetable yield and quality, it is necessary to strengthen the improvement of the arch shed soil.

Here, it is recommended that the vegetable farmers start from the following aspects:

First, the vegetable base fertilizer should be used as little as possible or without chemical fertilizer, especially to reduce the application of compound fertilizer.

Because the application of compound fertilizer is the main cause of secondary salinization and acidification of soil, it also affects the absorption of medium and trace element fertilizers.

The second is to increase the application of commercial organic fertilizer.

Manure (including fresh manure and dry chicken manure) is easy to cause burning due to incomplete decomposing, and these manures also have a lot of antibiotics, polluting the soil, it is recommended that farmers buy organic fertilizers, and it is best to use nitrogen in the purchase. Phosphorus potassium pure organic fertilizer to reduce the use of chemical fertilizers. Applying organic fertilizer as much as possible can increase the content of organic matter in the soil, improve the structure of soil aggregates, and improve soil fertility and water retention.

The third is to use a large gear rotary tiller to screw the ground.

Such a rotary tiller has a large rotary tiller, which is deeper than a conventional rotary tiller, can break the bottom of the plow, increase the thickness of the tillage layer, promote deep rooting, and improve the resistance of the vegetable. In addition, during the summer break, farmers are advised to plant leafy crops such as alfalfa and spinach. When they grow to about 10 cm, they will be deep into the soil. In addition to providing organic matter, they can also promote a large number of beneficial microorganisms and inhibit the growth of pathogenic bacteria. And promote the improvement of soil structure.
