Fertilizer special for rice breeding

Abstract

The invention discloses a fertilizer special for rice breeding. The fertilizer special for rice breeding comprises the following raw materials in parts by weight: 20-50 parts of cow dung, 3-20 parts of kelp residue, 30-50 parts of peat, 30-50 parts of urea, 3-11 parts of ammonium dihydrogen phosphate, 2-9 parts of sodium pyrophosphate, 3-11 parts of potassium fulvic acid, 2-8 parts of potassium 4-butanoate, 2-5 parts of calcium nitrate, 1-3 parts of zinc citrate, 2-4 parts of copper sulfate, 2-5 parts of manganese sulfate, 1-3 parts of ferrous sulfate, 2-5 parts of sodium molybdate, 2-5 partsof boric acid, 1-5 parts of a microbial agent, 1-3 parts of chitosan, and 10-35 parts of modified montmorillonite. The fertilizer special for rice breeding is reasonable in formula, complete in nutrition, good in slow-releasing effect, high in utilization rate, and capable of promoting the growth of breeding rice, and increasing the breeding yield.

Description

technical field [0001] The invention relates to the technical field of rice breeding, in particular to a special fertilizer for rice breeding. Background technique [0002] Rice is the main food crop in my country, and the improvement of rice quality and yield has attracted more and more attention. The quality of seeds is the basis for realizing high-quality, high-yield and high-efficiency production of rice, and the level of seed production is directly related to my country's food security. Although the research on rice breeding has progressed rapidly in recent years, in the process of rice breeding, the yield of its seed production is greatly affected by the experience of the technicians and the quality of the climatic conditions. Therefore, in the process of seed production, there are The defect of low efficiency, in the process of rice breeding, fertilization is a very important step.

Problems solved by technology

Although rice breeding research has progressed rapidly in recent years, in the process of rice breeding, the seed production yield is greatly affected by the experience of technicians and the quality of climatic conditions. Therefore, in the process of seed production, there are The defect of low efficiency, in the process of rice breeding, fertilization is a very important step

However, there are some unreasonable factors in the composition of the existing fertilizers, which lead to a decrease in the nutrient utilization rate of the fertilizers, requiring repeated topdressing, labor-intensive, and increased costs. At the same time, the ecological environment including the soil environment has been seriously damaged.
