Basal fertilizer for high-yield land of winter wheat of irrigated area of fluvo-aquic soil district of North China Plain

Abstract

The invention relates to a basal fertilizer for a high-yield land of winter wheat of an irrigated area of a fluvo-aquic soil district of North China Plain and belongs to the field of agricultural chemical fertilizers. The basal fertilizer is prepared from a nitrogen fertilizer, a phosphate fertilizer, a potassium fertilizer and clay and is characterized by comprising the ingredients in percentageby mass: 16%-17.5% of nitrogen fertilizer by pure nitrogen, 10% of phosphate fertilizer by phosphorus pentoxide, 8% of potassium fertilizer by potassium oxide and the balance of clay. According to thebasal fertilizer, through optimizing a proportioning ratio of the nitrogen fertilizer, the phosphate fertilizer and the potassium fertilizer, the thinking set of plagiarism of the existing compoundedfertilizers is broken through, and the high yield of the winter wheat of the irrigated area of the fluvo-aquic soil district of the North China Plain is promoted.

Description

technical field [0001] The invention belongs to the field of agricultural chemical fertilizers, and further relates to a wheat compound fertilizer. Background technique [0002] In recent years, the problem of excessive basal fertilizer application in winter wheat planting is common, which not only wastes chemical fertilizers, has low efficiency of chemical fertilizer utilization, but also brings serious environmental pollution problems. The reasons for this problem are: first, the amount of fertilizer applied by farmers is unscientific; second, the ratio of the three basic nutrients nitrogen, phosphorus and potassium does not meet the actual needs. It is a common measure to configure compound fertilizers that meet the needs of crops by adjusting and optimizing the proportions of the three nutrient elements of nitrogen, phosphorus and potassium. The key is to regulate the supply and speed of soil nutrients through fertilization to meet the needs of crops. Soil is a natural ...

AI Technical Summary

Problems solved by technology

If this kind of compound fertilizer is applied according to nitrogen, the application amount of phosphorus and potassium exceeds the demand of winter wheat, and long-term application will lead to the enrichment of phosphorus and potassium in cultivated land soil

Due to the high content of potassium fertilizer, the price of this kind of chemical fertilizer is also relatively high, which increases the cost of planting

The three-element balanced compound fertilizer ignores the adjustment effect of the soil on the supply of phosphorus and potassium, and ignores the difference in the demand for the three elements by crops, resulting in excessive application of chemical fertilizers.
