Special synergistic compound fertilizer for wheat and preparation method thereof

Abstract

The invention discloses a special synergistic compound fertilizer for wheat and a preparation method of the special synergistic compound fertilizer. The fertilizer comprises a basic compound fertilizer, a phosphorus synergist and urea formaldehyde, wherein the phosphorus synergist comprises humic acid, polyglutamic acid, carboxymethyl chitosan, chelated trace elements and sodium methylene bis-naphthalene sulfonate. Therefore, with the application of the special synergistic compound fertilizer for wheat, the fertilizer can meet the nutrient requirements of wheat for macroelements, medium elements and microelements in the whole growth period, can improve the nutrient effectiveness, especially phosphorus, can significantly reduce fixation of phosphorus by soil, improves the phosphorus activity, can promote root growth, meets the requirements of wheat for phosphorus in the overwintering period, and further improves the wheat yield.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a special synergistic compound fertilizer for wheat and a preparation method thereof. Background technique [0002] As one of the most important food crops in the world and our country, wheat plays a pivotal role in food production. Wheat is planted in a very wide range in my country, and it is the third largest food crop next to corn and rice. In an intensive agricultural production system, to achieve high-quality and high-yield wheat requires sufficient input of large, medium and trace elements, among which nitrogen, phosphorus, Potassium, magnesium, zinc, iron, manganese and other large, medium and trace elements have a great influence on the yield and quality of wheat. However, in the actual production of wheat in my country, there are often irrational application of fertilizers. There is a lot of blindness in fertilization. The amount of fertilizer applied is...

AI Technical Summary

Problems solved by technology

However, in the actual production of wheat in my country, there are often irrational application of fertilizers. There is a lot of blindness in fertilization. The amount of fertilizer applied is too large, the ratio is unreasonable, and the utilization rate of fertilizers continues to decline. This not only increases the cost of planting, but also poses a threat to the environment.

[0003] Winter wheat is the main type of wheat cultivation in my country. Its growth period is as long as 230-240 days. After sowing in autumn, it will experience an overwintering period. During this period, the temperature is low, the growth of wheat is slow or stops, and the ability to absorb nutrients is weakened, especially in low temperature environments. , the availability of phosphorus in the soil is reduced, it is difficult to meet the phosphorus demand of wheat, and it is very easy to appear physiological phosphorus deficiency in wheat, resulting in hindered root development, reduced tillering, stiff seedlings, etc., affecting the growth of wheat

[0004] Therefore, existing fertilizers adapted to wheat production remain to be explored
