Special fertilizer for rice soil measurement formula and preparation method thereof

Abstract

The invention relates to a special fertilizer for a rice soil measurement formula and a preparation method thereof. The special fertilizer for the rice soil measurement formula comprises the following components in parts by weight: 40-70 parts of urea-ammonium nitrogenous fertilizer, 20-30 parts of urea phosphate, 20-30 parts of potassium chloride, 5-10 parts of neutral water soluble silicon fertilizer, 0.2-0.6 part of zinc sulfate, 0.2-0.5 part of ferrous sulfate, 0.2-0.4 part of borax, 0.01-0.1 part of compound sodium nitrophenolate, and 0.5-1 part of auxiliary material. The special fertilizer for the rice soil measurement formula can offer complete and balanced nutrients for rice lastingly and harmoniously, can be applied once without topdressing, can remarkably improve the quality and yield of the rice, has obvious economic benefit, and is applicable to most soil in rice planting areas in China.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a special fertilizer for rice soil testing formula and a preparation method thereof. Background technique [0002] Rice is an important food crop in my country. Its perennial planting area and total output both occupy the first place in food crops. Rice contains 76-79% starch, 8-15% protein, and 0.2-0.4% fat by weight, and contains high nutritional value. Many nutrients such as lysine, compared with other crops, the digestibility and absorption rate of the nutrients contained in rice are higher, which is most suitable for the needs of the human body, so rice is the main food in our country. [0003] The nutrients necessary for the normal growth and development of rice include carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, sulfur, iron, zinc, boron and silicon. Carbon, hydrogen, and oxygen account for the vast majority of the composition of pl...

AI Technical Summary

Problems solved by technology

Rice has a large demand for nitrogen, phosphorus, and potassium. Relying solely on soil supply cannot meet the needs of rice growth and development, and must be applied additionally. At present, conventional chemical fertilizers are often applied in multiple times to ensure sufficient chemical fertilizers for rice. Supply, but labor-intensive, time-consuming and labor-intensive, cost input increases, and the release rate of nutrients in fertilizers cannot be controlled. With the increase in nitrogen, phosphorus, and potassium application, a large number of nutrients are relatively enriched, which not only reduces the utilization rate, but also wastes resources. , has polluted the environment. With the relative excess of macronutrient elements, the content of trace elements in the soil can no longer meet the demand, and the deficiency of trace elements in rice is also increasing.

[0004] In response to these problems, a variety of coated slow-release fertilizers have been developed at home and abroad. Although the release of nutrient elements can be controlled to a certain extent, these coating materials are generally difficult to degrade by themselves, causing soil pollution and expensive price restrictions for coated fertilizers. its large-scale use

Urea-formaldehyde fertilizers are likely to cause environmental pollution and safety hazards due to the use of formaldehyde as a reactant during production.
