Problems solved by technology

At present, the large-scale planting of vegetables is developing rapidly, but the fertilization technology is relatively backward. Vegetable farmers apply fertilizer blindly based on experience, and the waste of fertilizer is serious. At the same time, it will cause problems such as soil acidification, secondary salinization, groundwater nitrate pollution and high nitrate content in vegetables.

Abstract

The invention belongs to the field of microbial fermentation and provides a preparation method of a fertilizer special for leaf vegetables. The preparation method uses poor fruits, dropped fruits, fruit residues, fruit and vegetable straw and other waste produced in the agricultural production as raw materials, mannitol, magnesium sulfate and zinc sulfate are added in secondary fermentation in a cooperating mode, the demands for nitrogen, phosphorus and potassium are balanced in the growth process of the leaf vegetables, and medium trace elements and especially magnesium and zinc can promote synthesis and photosynthesis of chlorophyll and have the obvious effect on the leaf vegetables. In addition, the microbial action of the special fertilizer reduces the nitrite content, nitrate nitrogen is converted into ammonium nitrogen, and absorption and utilization of leaf vegetables are promoted.

Description

technical field [0001] The invention belongs to the field of biological fermentation and specifically provides a method for preparing a special fertilizer for leafy vegetables. Background technique [0002] At present, agricultural production generally depends on chemical fertilizers. On the one hand, it will cause environmental pollution. In fact, the non-point source pollution in rural areas is already quite serious, which has become a thorny problem. On the other hand, it will also affect the quality of agricultural products. After China's accession to WTO, the "organic green barrier" has also become an important obstacle to the export of agricultural products. Therefore, people have gradually realized that while using chemical fertilizers, it is necessary to increase the proportion of organic fertilizers, increase the content of organic matter in the soil, and continuously improve the original fertility of the land. Especially for economic crops such as vegetables, fruit...
