Problems solved by technology

However, the above measures for vegetable production areas, especially the production bases of special vegetables in the suburbs and vegetable bases with protective facilities, etc., the implementation of paddy and dry rotation will greatly restrict the economic benefits of farmers, and often the desalination is not thorough; use steam to sterilize Or chloropicrin and other sterilization effects are good, but the cost is too high and there are hidden dangers of safety and environmental pollution; at the same time, producers generally feel that it is very inconvenient to implement the above-mentioned measures alone, it takes a lot of work and time, and the effect is not ideal; therefore, timely Solving this problem has become an urgent task for agricultural researchers

Abstract

A multifunctional fertilizer is prepared by taking lime nitrogen, superphosphate, calcium magnesium phosphate fertilizer and potassium sulfate as materials, and formulating by proportioning. It achieves to inhibit soil fungus, to prevent soil acidification and salinization, and to improve fertilizer effect.

Description

technical field [0001] The invention belongs to the technical field of special fertilizers with combined use of fertilizers and pesticides, in particular to a vegetable-specific fertilizer and its application method for rectifying and overcoming obstacles in continuous cropping of vegetable production. Background technique [0002] The problem of continuous cropping obstacles of vegetable crops is becoming more and more intensified, and has become a major problem in agricultural production. Especially for melons and solanaceous fruits, continuous cropping obstacles are very common, which greatly restricts the production and development of these vegetables. According to research reports, continuous cropping obstacles are mainly caused by the increase of pests and diseases, nutrient imbalance caused by long-term continuous cropping, soil acidification and soil salt accumulation caused by improper fertilization, etc., resulting in crop physiological obs...
