Nitrogen-phosphorus-potassium compound fertilizer

Abstract

The invention relates to a nitrogen-phosphorus-potassium compound fertilizer, which consists of the following raw materials in part by weight: 8-12% of nitrogen, 16-20% of phosphorous, 25-40% of potassium, 13-17% of medium elements and 1-3% of trace elements. By using the nitrogen-phosphorus-potassium compound fertilizer, not only can the requirements of a farm crop on lots of the nitrogen, the phosphorus and the potassium be met; a plant is impelled to grow, so that a plant body is tall and big, branches are thick and strong, stem leaves are luxuriant, blades are fat and big, and grains are full; but also a root system can be effectively promoted to be developed; the farm crop is accelerated to grow and develop; the performances of drought resistance, cold resistance, lodging resistance and resistance to diseases and insect pests are improved; fruits are mature ahead of time; furthermore, the trace elements such as ferrum, boron, arsenic, manganese, copper, cobalt, molybdenum and the like, which are needed for the growth of the plant, are replenished for soil; the synthesis and the stability of chlorophyll are promoted; an in-vivo redox reaction is participated; the biological nitrogen fixation and the development of a generative organ are promoted; and the yield of the farm crop can be further improved.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a nitrogen, phosphorus and potassium compound fertilizer. Background technique [0002] In the process of plant growth and development, it needs to absorb carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, manganese, boron, uranium, zinc, molybdenum and other elements from the soil as its food , but the content of these elements in general soil is far from enough, and must be supplemented by fertilizers, while the traditional nitrogen, phosphorus, and potassium fertilizers have a single nutrient and cannot meet the growth needs of plants, resulting in insufficient nutrient supply for plants during their growth , thus leading to production reduction, death and other phenomena, bringing economic losses to agricultural planting, which is an urgent problem to be solved. Contents of the invention [0003] In order to solve the problems encountered in the app...
