Newly built greenhouses remember â€œthree increase and two attentionsâ€ and easily increase soil fertility

In the construction of new greenhouses, most of the mature soil on the surface layer has been destroyed for the construction and leveling of the land. Most of the soil for planting vegetables is raw soil. Such soil lacks organic matter and requires a large amount of organic fertilizer. The following measures can be taken for fertile soil.

Increasing the application rate of livestock, poultry manure

Most of the new sheds are raw soil, lack of organic matter, and a large amount of organic fertilizers, such as pig manure, chicken manure and other livestock and organic fertilizers. The new shed can increase the amount per acre to about 35 cubic meters to improve the physical and chemical properties of the soil.

Adding Biological Bacterial Fertilizer

Newly built greenhouses contain less microbial content in the soil. Even if a large amount of organic fertilizer is applied to the soil of the greenhouse, because the soil lacks microorganisms, the organic fertilizer cannot be quickly decomposed into soil organic matter. Therefore, when applying organic fertilizer in the soil, it is necessary to pay attention to the application of biological fertilizer. Quickly replenish microorganisms in the soil.

Adding commercial organic fertilizer

The organic matter content of commercial organic fertilizer is high, which helps the soil to quickly replenish organic matter after use. It can be applied to the new greenhouse soil for the first time, combined with the application of commercial organic fertilizer, about 500 kg per mu, which can guarantee vegetables. The nutrients needed in the early growth stage.

Attention to supplement nitrogen, phosphorus, potassium fertilizer

The content of nitrogen, phosphorus and potassium in the newly-built greenhouse soil is extremely low. In order to make the plant grow better, the vegetable farmers must 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.

Pay attention to the supplement of trace elements in

The lack of medium and trace elements in the soil of new greenhouses should pay attention to the application of calcium and magnesium fertilizers. 100 kg of calcium magnesium phosphate or superphosphate can be applied per acre to supplement soil nutrients, and multi-element mineral fertilizer can also be applied to improve the quality of vegetables.
