Special fertilizer for flare opening stage of corn

Abstract

The invention mainly relates to the technical field of planting, and discloses a special fertilizer for the flare opening stage of corn. The special fertilizer for the flare opening stage of the cornis prepared from the following raw materials: urea, calcium superphosphate, potassium chloride, magnesium sulfate, borax, zinc sulfate, biotin, L-cysteine, corn stigma, lactic acid bacteria and a Chinese holly extract. The special fertilizer for the flare opening stage of the corn is balanced in nutrition, promotes absorption and utilization of the corn in the flare opening stage, improves the vegetative growth and the reproductive growth of the corn, and promotes fullness of grains in the later stage of the corn, and the yield reaches 962 kg / mu (a Chinese unit of area); the corn stigma is fermented by the lactic acid bacteria to turn wastes into treasures and produce a large amount of small molecular nutrients, so that the absorption of the corn is facilitated, the reproductive growth ofthe corn is promoted, flowering pollination of the corn is facilitated, and the seed setting rate of corn ears is increased; the biotin and the L-cysteine are added for preparing microcapsules to promote the vegetative growth of the corn, so that corn stalks are thick and strong, roots are developed, and absorption and transformation of nutrients are facilitated; and the Chinese holly extract canenhance the disease resistance of the corn, reduce the rate of diseases and pests and promote increase of the corn yield.

Description

technical field [0001] The invention mainly relates to the technical field of planting, in particular to a special fertilizer for corn at the trumpet-mouth stage. Background technique [0002] Corn, also known as corn, corn, corn, and cob, is one of the main crops in my country. It is an annual grass herb, an important food crop and an important source of feed, and it is also the food crop with the highest total output in the world; corn is rich in nutrients , has high health value, can regulate blood sugar, enhance resistance, improve eyesight, resist oxidation, anti-aging, suppress cancer and fight cancer; The growth is very vigorous, the volume expands rapidly, the dry weight increases sharply, and the various organs begin to compete for nutrients. Therefore, the big trumpet period is the period in which the corn needs the most fertilizer and the fertilizer intensity is the period. Currently, the traditional corn planting method is Use 30-35kg of urea per mu during the bell...

[0002] Corn, also known as corn, corn, corn, and cob, is one of the main crops in my country. It is an annual grass herb, an important food crop and an important source of feed, and it is also the food crop with the highest total output in the world; corn is rich in nutrients , has high health value, can regulate blood sugar, enhance resistance, improve eyesight, resist oxidation, anti-aging, suppress cancer and fight cancer; The growth is very vigorous, the volume expands rapidly, the dry weight increases sharply, and the various organs begin to compete for nutrients. Therefore, the big trumpet period is the period in which the corn needs the most fertilizer and the fertilizer intensity is the period. Currently, the traditional corn planting method is Use 30-35kg of urea per mu during the bell-mouth period of corn, dig deep pits, cover the soil after fertilization, and apply less or postpone the application in a well-growing corn field, otherwise, apply more and apply in advance; simply apply urea , so that the nutrition obtained by corn is relatively simple, which cannot meet the nutritional needs of the whole plant of corn, and has an adverse effect on the growth and yield of corn
