When the new shed is built, for the convenience of operation, the mature soil of the surface layer is excavated by an excavator and used to pile up the shed wall. The soil used to grow vegetables is mostly about 1.5 meters from the surface of the soil. Soil organic matter is lacking, so it is necessary to supplement organic fertilizer in large quantities.

One is to increase the amount of manure such as chicken manure. Most of the newly built sheds are raw soil and lack of organic matter. Therefore, it is necessary to supplement the organic fertilizer in large quantities, such as rice husk, chicken manure and other organic fertilizers, which can increase the amount of ar in the amount of 35 yuan. Although these organic fertilizers cannot be applied, the soil cannot be increased rapidly. Organic matter in the middle, but it can improve the physical and chemical properties of the soil to some extent.

The second is to increase the application of biological fertilizer. In the newly built greenhouse, the amount of various microorganisms in the soil is small. Even if a large amount of organic manure such as chicken manure or rice husk is applied, the organic fertilizer is not rapidly decomposed into soil organic matter because of the lack of microorganisms in the soil. Therefore, when farmers use organic fertilizers such as rice husk and chicken manure in the newly-built greenhouse soil, they must pay attention to the application of biological fertilizers, such as the application of antibacterial 968 per acre, the rooting of roots and anti-dead trees, etc. 40 ~70 kg to quickly replenish microorganisms in the soil.

The third is to increase the application of commercial organic fertilizer. Commercial organic fertilizers have high organic matter content and help the soil to quickly replenish organic matter after use. After the first application of manure to the newly-built greenhouse soil, the vegetable grower can apply the commercial organic fertilizer in combination with 500 kg per mu, which can ensure the nutrition required in the early stage of vegetable growth.

The fourth is to pay attention to supplementing NPK fertilizer. The soil in the new greenhouse is all raw soil, and the content of nitrogen, phosphorus and potassium in the soil is extremely low. Therefore, it is necessary to pay attention to the application of nitrogen, phosphorus and potassium fertilizers when applying the base fertilizer. Generally, about 50 kg of fertilizer is used per mu.

The fifth is to pay attention to the supplement of trace elements. For vegetables to grow healthily, not only a large number of elements such as NPK, but also more than 10 kinds of medium and trace elements such as calcium, iron and boron are needed. The lack of medium and trace elements in the newly-built greenhouse soil has become a prominent problem that restricts the high yield and quality of vegetables. The author suggests that after the vegetable farmers build a greenhouse, they should pay attention to the application of calcium and magnesium fertilizers, and apply 100 kg of calcium magnesium phosphate or superphosphate to supplement soil nutrition. In addition, the growth of vegetables requires several trace elements such as iron, manganese, boron, zinc, copper, molybdenum and chlorine. In this regard, vegetable farmers can apply multi-element mineral fertilizers, such as grass and vegetable-derived compound plants, full-nutrition mineral element fertilizer, etc., about 50 kg per mu.
