Problems solved by technology

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. For this reason, people began to seek more environmentally friendly and safer fertilizers.

Abstract

The invention discloses a compound fertilizer with difficult-caking effect for rice. The compound fertilizer is prepared from the following raw materials of urea, ammonium nitrate, potassium sulfate,calcium magnesium phosphate fertilizer, compost organic fertilizer powder, diatomaceous earth, and modified sepiolite; the compost organic fertilizer powder comprises the following raw materials in parts by weight: livestock and poultry manure, crop straw, humus soil and rice bran. The compound fertilizer has the advantages that by adding the modified sepiolite and other raw materials, the dispersivity of the compound fertilizer is improved, and the agglomeration phenomenon is relieved.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a compound fertilizer for rice that is not easy to agglomerate. 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 ...
