Special compound fertilizer for barley

Abstract

The invention provides a special compound fertilizer for barley, 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 ofpotassium 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 barley germ oil. The compound fertilizer is suitable for the germination and ripening stage of the barley, improves soil fertility, can loosen the soil to increase soil organic matters, and reduces the occurrence of root pestsand diseases.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a special compound fertilizer for barley. Background technique [0002] Barley is an important food crop and economic crop, and plays an important role in people's livelihood and national economy. Effective use of limited land resources to improve the yield and quality of barley crops is the direction and eternal subject of people's efforts. [0003] The growth and development of barley needs to absorb more than 20 kinds of mineral elements, mainly including nitrogen, phosphorus, and potassium, three macroelements; sulfur, calcium, magnesium and other macroelements, as well as iron, manganese, boron, and copper. Zinc, sodium and other trace elements. Barley growth requires the most nitrogen, followed by phosphorus and the least potassium. In addition, zinc plays a positive role in the synthesis of endogenous auxins such as indole acetic acid in barley, and iron...

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 barley growth
