Organic fertilizer for facilitating yield increase of rice

Abstract

The invention relates to an organic fertilizer for facilitating yield increase of rice. The organic fertilizer comprises the following raw materials in parts by weight: 80-100 parts of farmyard material, 0.2-1 part of polyaspartic acid, 0.7-1.6 parts of vermiculite powder, 2-4 parts of Bacillus subtilis preparation, 15-20 parts of urea, 10-15 parts of diammonium phosphate, 15-20 parts of potassium chloride and 0.5-2 parts of zinc sulfate, wherein the total count of effective living bacteria of the Bacillus subtilis preparation is no less than 0.2 billion spores/g. According to the invention, the farmyard waste materials are utilized for the second time, thereby achieving the advantages of greenness and environment friendliness, and simultaneously increasing the contents of nitrogen, phosphorus, potassium and other elements in the organic fertilizer; the polyaspartic acid and the vermiculite powder can effectively increase the rice yield and improve the soil structure; and the Bacillus subtilis preparation can enhance the antivirus capability of rice, remove peculiar smell and purify water quality. Thus, the organic fertilizer achieves the advantages of moisture and fertility preservation, soil improvement, low cost, rice yield and quality increase and the like, has no residue and causes no pollution, thereby having favorable popularization and application prospects.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to an organic fertilizer which is beneficial to improving the yield of rice. Background technique [0002] Paddy rice is a kind of herbaceous Oryza genus, and the fruit is paddy rice, which is called brown rice after the chaff is removed, and the rice bran layer can be obtained by grinding the brown rice. 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. [0003] 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 pu...
