Special-purpose fertilizer for wheat and uses thereof

Abstract

The invention discloses a fertilizer special for wheat and an application thereof. In the fertilizer, the mass ratio of nitrogen, phosphorin, potassium, sulphur and zinc is 12-15:17-20:10-15:7-8:0.5-1; the nitrogen is selected from at least one of urea, ammonium sulphate and monoammonium phosphate; the phosphorin is monoammonium phosphate; the potassium is potassium sulphate; the sulphur is selected from at least one of the ammonium sulphate and potassium sulphate and the zinc is zinc sulphate. The fertilizing method of wheat of the invention is divided into two stages; basic fertilizers use the fertilizer special for wheat of the invention and the additional nitrogen fertilizer is dressed on two stages, namely setting stage and booting stage of the wheat. The application of the fertilizer special for wheat of the invention and the matching fertilizing method realize nutrient balance of nitrogen and sulphur and have significant influences on the growth, yield and processing quality ofwheat.

Description

technical field [0001] The invention relates to a special fertilizer for wheat and its application. Background technique [0002] With the continuous development of my country's food industry and the expansion of demand, the planting area of ​​strong gluten wheat varieties is increasing. The Huanghuai wheat area is the largest main wheat producing area in my country, and the total wheat output and area account for 55% and 64% of the country's total respectively. Taking Henan Province as an example, the area of ​​high-quality wheat with strong gluten has reached more than 70% of the harvested area of ​​wheat in 2007. However, the quality of wheat grain in these areas often fails to meet the purchase standards of enterprises, which affects farmers' income. One of the main reasons for this problem is that wheat planting technology lags behind and management is unreasonable. Fertilization is one of the important factors affecting wheat quality. In these areas, the typical pr...

AI Technical Summary

Problems solved by technology

The entire growth period of winter wheat is about 200 days, while the fertilizer effect period of quick-acting nitrogen fertilizer is about 30-50 days. Obviously, the growth period of wheat cannot meet the nutrient demand with only one base fertilizer.

Chinese patent CN1673199A discloses a compound fertilizer suitable for use as base fertilizer for wheat in the lower reaches of the Yellow River. This patented product reduces the proportion of nitrogen in the formula, but does not increase the sulfur element in the formula. For the strong gluten that accounts for a large proportion in this area Wheat grain protein accumulation is extremely unfavorable
