Organic fertilizer for paddy rice

Abstract

The invention relates to organic fertilizer for paddy rice. The organic fertilizer is prepared from the following raw materials in parts by weight: 45 to 60 parts of wormcast, 6 to 10 parts of potassium fulvate, 1 to 2 parts of chitosan oligosaccharide, 3 to 5 parts of water-soluble silicon fertilizer, 1 to 2 parts of a microbial agent, 10 to 15 parts of urea, 6 to 12 parts of calcium superphosphate and 8 to 12 parts of potassium chloride. According to the fertilizer disclosed by the invention, by adding the wormcast, the contents of organic matters, minerals and various trace elements in the fertilizer are increased and greenness and environment friendliness are realized. In addition, by adding the potassium fulvate, the chitosan oligosaccharide, the water-soluble silicon fertilizer and the microbial agent, the effects of improving the soil structure, enhancing the antiviral ability of the paddy rice, reducing the contents of heavy metals and the like can be realized. In a word, the fertilizer disclosed by the invention has abundant nutrient elements and the advantages of preserving moisture and fertility, improving the disease resisting and preventing abilities of crops, and protecting ecological environment of soil; the yield and the quality of the paddy rice are greatly improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to an organic fertilizer for rice. Background technique [0002] Nearly half of the world's population relies on rice as a staple food. Rice is a direct economic crop. In addition to being edible, it can also be used as industrial raw materials for wine making and sugar refining. Rice husk and rice straw can be used as feed. The main rice producing areas in my country are mainly the Northeast region, the Yangtze River Basin, and the Pearl River Basin. At present, the fertilization method of rice is mainly to use chemical fertilizers for fertilization, although chemical fertilizers can speed up the growth of rice and achieve the purpose of high yield. However, with the extensive use of chemical fertilizers, the problems of soil hardening, salinization, and compaction have begun to emerge, as well as the decline in the quality of rice and the presence of drug residues in rice.
