Zinc-enriched corn high and stable yield cultivation technology

Abstract

The invention relates to the technical field of agricultural planting, in particular to a zinc-enriched corn high and stable yield cultivation technology. The zinc-enriched corn high and stable yield cultivation technology comprises the following steps: before sowing corn seeds, soaking the corn seeds in a 500-700 times diluent of fructose diphosphate, pouring dwarfing liquid to corn roots every 10 days after the height of corn seedlings reaches 60cm, spraying a grape stalk extract to corn leaf surfaces every 5 days after the corns enter a small trumpet period, and injecting a 400-500 times diluent of lignin zinc carbonate into corn cob flower axes from opening parts of corn cobs after the corns enter a kernel formation period. As for the corns planted by adopting the method, the yield is higher, clusters are full, the dwarfing effect is good, and organic zinc content in the corns is 38-42mg / kg.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a high-yield and stable-yield cultivation technology for zinc-rich corn. Background technique [0002] Corn is an annual gramineous herbaceous plant. It is an important food crop and an important source of feed. It is also the food crop with the highest total output in the world. It is rich in protein, fat, vitamins, trace elements, cellulose and polysaccharides, etc. It has high development potential. Great potential for nutritious, high biologically functional foods. [0003] Zinc is one of the essential trace elements for the human body. It plays an extremely important role in important physiological processes such as human growth and development, reproductive inheritance, immunity, and endocrine. It is dubbed "the flower of life", "the source of intelligence", " "Marriage Harmonious Elements" reputation, zinc-rich products are very popular among consumers. In o...

Problems solved by technology

[0003] Zinc is one of the essential trace elements for the human body. It plays an extremely important role in important physiological processes such as human growth and development, reproductive inheritance, immunity, and endocrine. It is dubbed "the flower of life", "the source of intelligence", " "Marriage Harmonious Elements" reputation, zinc-rich products are very popular among consumers. In order to meet the needs of consumers, the majority of growers also use the method of adding zinc fertilizer to the soil or spraying zinc fertilizer on the leaves to produce zinc-rich vegetables. Zinc fertilizers include inorganic zinc and organic zinc. Inorganic zinc includes zinc sulfate heptahydrate and zinc sulfate monohydrate, basic zinc sulfate, zinc chloride, zinc oxide, zinc sulfide, zinc phosphate, basic zinc carbonate, zinc glass, Organic zinc includes lignin zinc carbonate, zinc naphthenate emulsion and chelated zinc (Na2ZnEDTA). Inorganic zinc fertilizer is cheap, but it is not conducive to crop absorption. Although organic zinc fertilizer is more conducive to crop absorption, it is expensive and direct application Extremely costly to spread or spray
