Environmental protection fertilizer of green sorghum

Abstract

The invention relates to an environmental protection fertilizer of green sorghum, comprising a base fertilizer formula, a seedling fertilizer formula, a jointing fertilizer formula and a booting fertilizer formula. A base fertilizer formula, a seedling fertilizer, a jointing fertilizer and a booting fertilizer are based on night soil and animal manure, and various auxiliary raw materials are added, to make contents of nitrogen, phosphor and potassium in each stage accord with growth need of crops in the stage. The night soil and animal manure after decomposed and fermented, contain abundant nitrogen, phosphor, potassium and medium-trace elements; has advantages of long fertilizer efficiency and comprehensive nutrition; can satisfy requirement of sorghum continuous growth; can also improve physical structure of soil; can increase fertility of soil; when applied as the seedling fertilizer, can promote root growth, thereby laying a solid foundation for raising output; when applied as the jointing fertilizer, can promotes formation of more spikelet and more florets, thereby raising output; when applied as the booting fertilizer, can promote nutrient transfer, thereby guaranteeing growth requirement of seeds; and when integrally applied, can increase 10% of output. The obtained sorghum seeds have advantages of plump seeds, good color and good mouthfeel.

Description

technical field [0001] The invention belongs to the technical field of sorghum planting, in particular to an environment-friendly fertilizer for green sorghum. Background technique [0002] Sorghum is an annual herbaceous plant, also known as sorghum, milo, etc. It has the characteristics of high yield, strong adaptability, and strong fertility. It is one of the earliest cereal crops cultivated in my country. Large-scale planting has begun. Sorghum grains contain nutrients such as fat, protein, fiber and starch, and are important raw materials for brewing and starch industries. Sorghum grains can also be mixed with corn, peas, rice, peanuts, etc. to form pigeon feed. Sorghum grains can also satisfy People's dietary needs, especially the Japanese and Koreans are very respectful of sorghum rice. [0003] The growth half of sorghum is divided into three stages, which are: 1. Early growth period - from seedling emergence to jointing; 2. Middle growth period - from jointing to e...

AI Technical Summary

Problems solved by technology

Before these three stages, it is necessary to apply base fertilizer in the field, and then topdressing in the above three stages respectively. At present, the types of fertilization by growers are very confusing, and a large amount of chemical fertilizers are used, which not only reduces the potential of soil fertility, but also reduces the potential of sorghum. The grain quality and yield per mu, and the sorghum that uses a large amount of chemical fertilizers have been resisted by foreign customers, causing the growers to suffer great economic losses
