Problems solved by technology

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

Embodiment Construction

[0018] A kind of wheat compound fertilizer, is made up of urea, ammonium phosphate, Yunnan granular phosphate fertilizer, Canadian potassium fertilizer, and described urea, ammonium phosphate, Yunnan granular phosphate fertilizer, Canadian potassium fertilizer are by weight percentage:

[0019] Urea: 47%-56%

[0020] Ammonium phosphate: 22-34%

[0021] Yunnan Granular Phosphate Fertilizer 12-19%

[0022] Canadian potash 5-8%.

[0023] Specifically, the nitrogen (N) content of the urea is 47%, the phosphorus (P) content of the ammonium phosphate is 46%, the phosphorus (P) content of the Yunnan granular phosphate fertilizer is 16%, and the potassium (P) content of the Canadian potash fertilizer ( K) The amount is 60%.

[0024] Specifically, the urea, ammonium phosphate, Yunnan granular phosphate fertilizer, and Canadian potash fertilizer are by weight percentage:

[0025] Urea: 49.59%

[0026] Ammonium phosphate: 30.01%

[0027] Yunnan Granular Phosphate Fertilizer 15.69% ...

Abstract

The invention provides a compound fertilizer for wheat. The compound fertilizer is prepared from urea, ammonium phosphate, a Yunnan granular phosphate fertilizer and a Saskatchewan potash fertilizer and contains the ingredients in percentage by weight: 47-56% of urea, 22-34% of ammonium phosphate, 12-19% of Yunnan granular phosphate fertilizer and 5-8% of Saskatchewan potash fertilizer. The compound fertilizer has the advantages that shown by contrast experiments, under the conditions of the same content and the same formula, the wheat yield can be increased by 30-50% by using the fertilizer provided by the invention; fertilization is required once only, and the fertilizer has short acting and long acting combined efficacy, thereby being work-saving, timesaving, laborsaving, money-saving and environment-friendly.

Description

technical field [0001] The invention relates to a compound fertilizer for production, in particular to a wheat compound fertilizer. 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 wheat stems, a...
