Compound fertilizer applied to wheat

Abstract

The invention provides a compound fertilizer applied to wheat. The compound fertilizer comprises the following components by weight percent: 47-56% of urea, 38-55% of ammonium phosphate and 5-8% of Canada potash fertilizer. Compared with common fertilizers with same contents and same formulas, the compound fertilizer applied to the wheat, provided by the invention, has the advantages that the wheat yield can be increased by 30-50 % and only once fertilization is needed; the compound fertilizer applied to the wheat, provided by the invention, has a combined effect of long effect and short effect and is work-saving, labor-saving, time-saving, labor-saving, money-saving, green and environment-friendly.

Description

technical field [0001] The invention relates to a compound fertilizer for production, in particular to a compound fertilizer applied to wheat. Background technique [0002] Wheat is planted in a wide range in my country, and its growth and development need to absorb a variety of essential nutrients from the external environment, but among them, nitrogen, phosphorus, and potassium are the three elements that absorb the most and have the greatest impact on wheat growth and yield. ①The experiment showed that nitrogen element plays a very important role in promoting the number of spikes, increasing the grain size and improving the quality of wheat. ② The effect of phosphorus on wheat. Relevant experiments have shown that insufficient application of phosphorus can easily lead to hindered root development, reduced tillering, and non-emergence of stiff seedlings, which directly affect yield. ③Potassium can enhance the cold resistance of wheat, improve the lodging resistance of whe...

②The effect of phosphorus on wheat. Relevant experiments have shown that insufficient application of phosphorus can easily lead to hindered root development, reduced tillering, and non-emergence of stiff seedlings, which directly affect yield.

[0004] The existing wheat fertilizers are all short-acting fertilizers. After a short period of fertilization, the effectiveness of the fertilizer will be lost. The soil has no stamina, which will affect the yield of wheat. The whole growth cycle of wheat generally needs to be applied 2 to 3 times. of fertilizers, but also labor-intensive
