Abstract

The invention relates to a fertilizer for plants, and in particular relates to a controlled release composite fertilizer for soybean and a preparation method thereof. The controlled release composite fertilizer for soybean is prepared by fermented bean dregs, distillers' grains, sweet potato slices, fulvic acid, urea, diammonium phosphate, potassium chloride, zinc sulfate, fructus cnidii, sophocarpidine, radix euphorbiae lantu, salix leaves and gelatin according to a special proportion through a special preparation method. Organic fertilizer and inorganic fertilizer are combined together and are gradually released along with solubility of inorganic components and degradation of the organic fertilizer, so that release of the fertilizer is matched with growth demand of plants, thereby, further improving the yield of soybean. The fertilizer contains nitrogen, phosphorus and potash fertilizers as well as amino acids, enzymes, amides, cytokinin, beneficial biological strains and organic antibacterial substances, so that the quality of soybean is improved, and the content of trace nutritional ingredients is higher, therefore, the soybean is further in accordance with dietary standard of modern people.

Description

technical field [0001] The invention relates to a fertilizer for soybeans, in particular to a controlled-release compound fertilizer for soybeans and a preparation method thereof. Background technique [0002] Soybean is the fourth largest grain crop in my country and is also used as an oil plant. It is the main source of plant protein nutrition and high-quality oil nutrition for Chinese people; soybean meal is an indispensable source of protein feed for aquaculture. Soybean is an important crop in ecological agriculture and organic agriculture due to the nitrogen fixation effect of root nodules. Therefore, soybean planting plays a vital role. However, due to the limited arable land area in our country, it is mainly used for rice, wheat, soybean and other crops. It is difficult for soybean production to increase rapidly. The total production is seriously insufficient and the per unit yield is low. Fertilizer is a substance that provides the necessary nutrients for soybe...
