Fertilizer applying method for rice

Abstract

The invention discloses a rice fertilization method, which belongs to the technical field of crop fertilization, and the steps are as follows: (1) applying base fertilizer before transplanting, and the base fertilizer is specifically: applying 160-200 kg of bio-organic fertilizer per mu, 25-10-15 kg 30-50 kilograms of compound fertilizer, 3-5 kilograms of medium and trace element fertilizers; (2) tillering fertilizer is applied in the tillering stage, and the tillering fertilizer is specifically: 20-12-8 compound fertilizer 7-10 kilograms per mu; (3) Young panicle differentiation stage is applied with young panicle differentiation fertilizer, and the young panicle differentiation fertilizer is specifically: 3-10 kilograms of full water-soluble organic fertilizer per mu, 15-25 kilograms of 18-8-26 compound fertilizer; (4) ear stage, apply ear fertilizer , the ear fertilizer is specifically: 4-6 kg of quick-acting nitrogen fertilizer, 1-3 kg of potassium fertilizer, the quick-acting nitrogen fertilizer is urea, and the potassium fertilizer is potassium chloride. In the present invention, the fertilization is scientific and reasonable, the organic fertilizer is reasonably matched with the chemical, and the macroelement and the medium and microelement fertilizer are reasonably matched, so that the rice yield is high and the quality is good, and the problem of soil compaction can also be improved.

Description

technical field [0001] The invention belongs to the technical field of crop fertilization, and in particular relates to a rice fertilization method. Background technique [0002] Rice is one of the main food crops in the world, and about half of the world's population depends on rice as a staple food. China's rice cultivation area accounts for about 1 / 4 of the world's total rice cultivation area, while its output is about 37% of the world's total rice production and 45% of the country's total grain production. [0003] Rice is an annual herbaceous plant belonging to the Poaceae Oryza genus. The human edible part is caryopsis, commonly known as rice. With the development of science and technology, rice planting and cultivation are becoming more and more scientific, and fertilization in cultivation management is particularly important. [0004] And the main problem existing in rice fertilization at present is that fertilization is unscientific, and long-term application of ...
