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 corn growth

Abstract

The invention provides a special compound fertilizer for maize. The special compound fertilizer is prepared from the following raw materials in parts by weight: 12 to 18 parts of urea, 24 to 36 parts of mixed phosphorus fertilizers, 4 to 6 parts of sodium tetraborate, 3 to 4 parts of magnesium sulfate, 5 to 6 parts of zinc sulfate, 2 to 3 parts of sodium selenite, 3 to 6 parts of lobster manure, 6 to 8 parts of a soil conditioner, 34 to 38 parts of bean pulp, 12 to 14 parts of Muyu stone, 5 to 10 parts of negative electricity mineral powder, 20 to 24 parts of shrimp shell meal, 8 to 10 parts of oligosaccharins, and 4 to 5 parts of maize germ oil. The compound fertilizer is applicable to stages of maize germinating and maturation, improves the soil fertility, and can loosen soil to increase soil organic matter, and reduce the occurrence of root diseases and insect pests.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a special compound fertilizer for corn. Background technique [0002] Corn is an important food crop and economic crop. According to statistics, its yield and planting area are second only to rice and wheat, ranking third 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 corn crops is the direction and eternal subject of people's efforts. [0003] The growth and development of corn needs to absorb more than 20 kinds of mineral elements, mainly including nitrogen, phosphorus, and potassium, three major elements; sulfur, calcium, magnesium and other macroelements, and iron, manganese, boron, and copper. Zinc, sodium and other trace elements. Maize growth needs the most nitrogen, followed by phosphorus and the least potassium. In addition, zinc plays a ...
