Abstract

The invention discloses an efficient composite water-soluble fertilizer. The fertilizer comprises the following components in parts by weight: 80-130 parts of urea, 60-100 parts of mono-potassium phosphate, 100-150 parts of potassium sulfate, 40-80 parts of ammonium polyphosphate, 10-50 parts of medium elements, 10-50 parts of trace elements, 3-12 parts of humic acid, 1-5 parts of a composite microbial inoculant and 10-30 parts of composite amino acids. The medium elements are prepared by mixing EDDS chelated magnesium and EDDS chelated calcium; the trace elements are prepared by mixing EDDS chelated zinc, EDDS chelated manganese, EDDS chelated copper, EDDS chelated iron and boric acid; and the composite microbial inoculant is a mixture of bacillus aceticus, rhizobium and bacillus subtilis. The fertilizer is balanced and comprehensive in nutrients, high in crop absorption and utilization rate, simple in preparation method, capable of improving the ecological environment of soil, cropsand microorganisms, and capable of increasing the yield, improving the quality and enhancing the disease resistance and stress resistance when applied to planting of tomatoes and other crops.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a high-efficiency compound water-soluble fertilizer and its preparation method and application. Background technique [0002] Water-soluble fertilizer is a multi-component compound fertilizer that can be completely dissolved in water. It can be quickly dissolved in water and is more easily absorbed by crops, and its absorption and utilization rate is relatively high. More importantly, it can be applied to drip irrigation And other facility agriculture, realize the integration of water and fertilizer, and achieve the efficiency of saving water, fertilizer and labor. Compared with traditional superphosphate, granulated compound fertilizer and other varieties, water-soluble fertilizer has obvious advantages. Its main features are less dosage, convenient use, low cost of use, fast absorption by crops, and high utilization rate of nutrients. In this way, people can design formul...
