Preparation and application methods of stick fertilizer with synergy of reduced application of chemical fertilizers and increased application of organic fertilizers

Abstract

The invention provides a stick fertilizer with synergy of reduced application of chemical fertilizers and increased application of organic fertilizers. The stick fertilizer is prepared from organic materials, inorganic materials and auxiliary additive materials, wherein the organic materials are prepared from a finished product obtained by decomposing after composting mushroom residue, a finished product obtained by decomposing after composting straws, a finished product obtained by decomposing after composting livestock manure, a finished product obtained by decomposing after mixing and composting biogas residue and mushroom residue, a finished product obtained by decomposing after mixing and composting sludge and mushroom residue and a finished product obtained after decomposing peat and oil cakes; the inorganic materials are prepared from slow-release compound fertilizers and / or slow-release elemental chemical fertilizers; the auxiliary additive materials are prepared from copper sulfate, zinc sulfate, ferrous sulfate, molybdenum sulfate, ammonium molybdate, manganese sulfate, calcium chloride, fulvic acid or humic acid. Through the stick fertilizer, the organic fertilizers and the inorganic fertilizers are collaboratively applied; the stick fertilizer has the advantages that the application quantity of the chemical fertilizer is reduced, the application efficiency of the chemical fertilizers is improved, and the application quantity of the organic fertilizers is increased; the stick fertilizer is prepared by mixed pressing or separately pressing; the preparation method is simple; the stick fertilizer is deeply applied by drilling holes; the application frequency is low; the labor and the effort of operation are reduced; after the stick fertilizer is applied to fruit trees, the fruit trees are high in yield and high in quality.

Description

technical field [0001] The invention relates to a bar fertilizer used for fruit tree chemical fertilizer reduction and efficiency enhancement combined with labor-saving and labor-increasing application of organic fertilizers, as well as a preparation method and an application method. Background technique [0002] The excessive use of chemical fertilizers in my country is serious, and the situation of low soil organic matter content is serious, which leads to major problems such as environmental pollution, soil quality degradation, and agricultural product quality and quality safety. There is an urgent need to improve fertilization methods, increase fertilizer utilization efficiency, reduce unreasonable inputs, ensure effective supply of major agricultural products such as grain, and promote sustainable agricultural development. In 2015, the General Office of the State Council issued the "Opinions on Accelerating the Transformation of Agricultural Development Mode", proposing...

Problems solved by technology

However, there are deficiencies in the idea of ​​special setting: to overcome the problem of lack of labor force in the application of high-efficiency new fertilizers, first of all, to achieve labor-saving and labor-saving fertilization, and then to achieve high-efficiency nutrients; the integration of water and fertilizer requires irrigation facilities or irrigation systems. For facilities and In areas where the system is lacking, especially in the southern mountainous and hilly areas, fruit tree irrigation is basically dependent on the sky, and the promotion of water and fertilizer integration is more difficult; green manure, livestock and poultry manure utilization, straw returning and other chemical fertilizer replacement technologies also face the bottleneck of labor shortage
