When the new shed is built, for ease of operation, most of the ground surface of the mature soil is excavated by an excavator to be used for stacking the shed wall. The soil used to grow vegetables is mostly raw soil about 1.5 meters from the surface. The lack of organic matter in the soil requires a large amount of organic fertilizer.
The first is to increase the manure and other manure application rates. Most of the newly built sheds are raw soils, and organic matter is lacking. Therefore, a large amount of organic fertilizers, such as rice husk manure, chicken manure and other organic fertilizers, can be used to increase the amount of mu to about 35 square meters. After the application of these organic fertilizers, although it can not rapidly increase the organic matter in the soil, it can improve soil physical and chemical properties to some extent.
The second is the addition of biological bacteria fertilizer. In the new greenhouses, the soil has a low content of various microorganisms. Even if a large amount of manure such as chicken manure and rice husk manure is applied to the soil of the greenhouse, because of the lack of microorganisms in the soil, the organic fertilizers cannot be quickly decomposed into soil. Organic matter. Therefore, when the vegetable farmer applies organic manure such as rice husk manure and chicken manure in the soil of the new greenhouse, he must pay attention to the addition of biological bacterial fertilizer to quickly supplement the microorganisms in the soil.
The third is to increase commodity organic fertilizer. The organic content of commodity organic fertilizer is high, and it helps the soil to quickly replenish organic matter after use. The vegetable growers can apply manure in combination with the application of commodity organic fertilizer for the first time in the soil of the new greenhouse, and apply about 500 kilograms per mu. This can ensure the nutrition needed in the early stage of vegetable growth.
The fourth is to pay attention to nitrogen, phosphorus and potassium fertilizers. The soil in the newly-built greenhouse is raw soil. The content of nitrogen, phosphorus and potassium in the soil is extremely low. Therefore, when applying basal fertilizer, we must pay attention to increasing nitrogen, phosphorus and potassium fertilizers. Farmers can increase the amount of nitrogen, phosphorus, and potassium fertilizers. In general, about 100 pounds of chemical fertilizer per mu.
Fifth, pay attention to supplement the trace elements. The lack of trace elements in the soil of new greenhouses has become a prominent issue that restricts the high yield and quality of vegetables. The author suggests: After the vegetable grower builds the greenhouse, should pay attention to increase calcium, magnesium fertilizer, can apply 100 kg calcium magnesium phosphate fertilizer or superphosphate, etc., to supplement the soil nutrition. In addition, the growth of vegetables also requires trace elements such as iron, manganese, boron, zinc, copper, molybdenum, chlorine, etc. Therefore, vegetable farmers can apply multi-element mineral fertilizers to improve the quality of vegetables.
