Special compound fertilizer for wheat yield increase

Abstract

The invention provides a special compound fertilizer for wheat yield increase, and the special compound fertilizer is prepared from the following raw materials by weight: 12-18 parts of urea, 24-36 parts of mixed phosphate fertilizer, 4-6 parts of sodium tetraborate, 3-4 parts of magnesium sulfate, 5-6 parts of zinc sulfate, 2-3 parts of sodium selenite, 12 parts of potassium dihydrogen phosphate,7.5 parts of potassium sulfate, 0.09 part of a microbial agent, 6 parts of traditional Chinese medicine slag, 14 parts of diatomaceous earth, 4 parts of a soil activator and 4-5 parts of wheat germ oil. The compound fertilizer is suitable for the germination and ripening stage of the wheat, improves soil fertility, can loosen the soil to increase soil organic matters, and reduces the occurrence of root pests and diseases.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a special compound fertilizer for increasing wheat production. Background technique [0002] Wheat is an important food crop and economic crop. According to statistics, its output and planting area rank first in the world. It plays an important role in people's livelihood and national economy. Effective use of limited land resources to improve the yield and quality of wheat crops is the direction and eternal subject of people's efforts. [0003] There are more than 20 kinds of mineral elements that wheat needs to absorb for growth and development, mainly including nitrogen, phosphorus, and potassium, three major elements; sulfur, calcium, magnesium and other macroelements, as well as iron, manganese, boron, and copper. Zinc, sodium and other trace elements. The growth of wheat requires the most nitrogen, followed by phosphorus and the least potassium. In addit...

Problems solved by technology

However, during the use of urea, it is easy to lose through volatilization, leaching, decomposition and runoff, resulting in low fertilizer utilization rate. According to statistics, the seasonal utilization rate is only about 30%, which not only causes waste of chemical fertilizers, but also Pollution of air, water, soil and other environments on which human beings depend

[0005] At present, there is a lack of fertilizers that can effectively promote all stages of wheat growth
