Embodiment 1

[0020] A high-yield corn dense planting cultivation method, comprising the following steps: select the corn variety Zhengdan 958, plant it in Shagou Town, Yishui County, apply 5500kg of pig manure, 15kg of urea, 8kg of potassium chloride, 25kg of superphosphate, and urea per mu. Slow-release fertilizer 15kg; use a subsoiling full-layer fertilization precision sowing machine, subsoil 25 cm, break the plow bottom layer, increase soil water storage capacity, and reduce water and fertilizer loss; use the precision sowing machine to apply 6 layers of fertilizer in the whole growth period to the corn root system around, which is conducive to absorption during the whole growth period and reduces leaching loss;

[0021] Corn seeds are treated with special organic seed coating agent for corn. The composition of the seed coating agent includes: actinomycin, jelly-like bacillus, azospirilla, diatomaceous earth, spice powder, indole acetic acid, potassium sulfate, magnesium sulfate, Zinc ...

Embodiment 2

[0026] Select the corn variety Tiantai No. 10 and plant it in Shagou Town, Yishui County. Apply 5500kg of pig manure, 15kg of urea, 8kg of potassium chloride, 25kg of superphosphate, and 15kg of urea slow-release fertilizer per mu of land; use deep pine for full-layer fertilization Precision sowing machine, deep loosening 25 cm, breaks the plow bottom layer, increases soil water storage capacity, and reduces water and fertilizer loss; through the precision sowing machine, apply 6 layers of fertilizers in the whole growth period around the corn root system, which is conducive to absorption during the whole growth period and reduces leaching ; Field planting is: planting in a row, the width of the row is 120-140 cm, the height of the row is about 20 cm, the width of the row is planted, the row spacing of the wide row is 100-150 cm, the row spacing of the narrow row is 40-50 cm, and the spacing of the holes is 35-40 cm. cm, 3 plants per hole, sow the treated seeds double-grained i...

Abstract

Disclosed is a high-yield maize culture method. The method comprises the steps of seed treatment, field planting, field management and water and fertilizer management. The high-yield maize culture method is characterized in that according to seed treatment, maize seeds are treated through an organic seed coating for maize, and the seed coating is prepared from actinomycin, bacillus mucilaginosus, azospirillum brasilense, kieselguhr, carry powder, heteroauxin, potassium sulphate, magnesium sulfate, zinc sulfate, alpha-pimacol growth regulator, EDTA-2Na chelating agent, humic acid and grass peat.

Description

technical field [0001] The invention relates to a high-yield cultivation method for corn. Background technique [0002] my country is a populous country, and corn is one of the three major food crops. Corn production occupies a very important position in my country's agricultural production and national economy. The development of corn production has great practical significance for increasing farmers' income, ensuring national food security and even economic security. Although the total annual production of corn in my country has developed rapidly, the total annual production of corn is insufficient, and there is still a large gap with the market demand of my country's corn, and a large amount of imports is required every year. Affected by the lack of per capita agricultural land resources in my country and the adjustment of agricultural planting structure, it is difficult to expand the corn planting area in my country. At present, my country's agricultural production la...
