Embodiment 1

[0019] A high-yield corn dense planting cultivation method, comprising the following steps: selecting a corn variety Zhengdan 958, planting in Shagou Town, Yishui County, applying 5500kg of pig manure, 15kg of urea, 8kg of potassium chloride, 25kg of superphosphate, urea per mu of land 15kg of slow-release fertilizer; using a deep-soaking full-layer fertilization precision seeder, deep loosening 25 cm, breaking the bottom of the plow, increasing the soil water storage capacity, and reducing the loss of water and fertilizer; applying 6 layers of fertilizer throughout the growth period to the corn root system through the precision seeder The surrounding area is conducive to absorption during the whole growth period and reduces leaching; field planting is as follows: planting on a border, the width of the border is 120-140 cm, the height of the border is about 20 cm, and the wide and narrow rows are planted. The wide row spacing is 100-150 cm, and the narrow row spacing is 40 to 5...

Embodiment 2

[0023] The corn variety Tiantai No. 10 was selected and planted in Shagou Town, Yishui County. Each mu of land was applied with 5500kg of pig manure, 15kg of urea, 8kg of potassium chloride, 25kg of superphosphate, and 15kg of urea slow-release fertilizer; full-layer fertilization was adopted. The precision seeder, deeply loosens 25 cm, breaks the bottom of the plow, increases the soil water storage capacity, and reduces the loss of water and fertilizer; through the precision seeder, 6 layers of fertilizers in the whole growth period are applied around the corn root system, which is conducive to the absorption of the whole growth period and reduces the leaching loss. ; Field planting is as follows: planting from a border, the width of the border is 120-140 cm, and the height of the border is about 20 cm. Planting in wide and narrow rows, the wide row spacing is 100-150 cm, the narrow row spacing is 40-50 cm, and the hole spacing is 35-40 cm. cm, 3 plants per hole, sow the treat...

Embodiment 3

[0027] The corn variety Danyu 86 was selected and planted in Shagou Town, Yishui County. Each mu of land was applied with 5500kg of pig manure, 15kg of urea, 8kg of potassium chloride, 25kg of superphosphate, and 15kg of urea slow-release fertilizer. The seeding machine, deep loosening 25 cm, breaks the bottom of the plow, increases the soil water storage capacity, and reduces the loss of water and fertilizer; through the precision seeder, 6 layers of fertilizers in the whole growth period are applied around the corn root system, which is conducive to the absorption of the whole growth period and reduces the leaching loss; The field planting is as follows: planting from the border, the width of the border is 120-140 cm, the height of the border is about 20 cm, and the width of the row is wide and narrow. , 3 plants per hole, sow the treated seeds twice in the ditch at each point, cover soil while sowing, cover soil 1 inch and be practical, and leave 5700 to 6700 seedlings per m...

Abstract

The invention relates to a high-yield corn dense planting cultivating method, which comprises the following steps of seed treatment, field planting, field management, weeding and management of water and fertilizer. The good hybrid corn variety with the characteristics of dense planting resistance, dwarf, compact plant type, matured live stem, proper mature period, no balding of fruit cluster, lodging resistance, and pest and disease resistance; furrows are formed for planting, the width of each furrow is 120-140cm, and the height of each furrow is about 20cm; the wide and narrow line planting type is adopted, the distance of wide lines is 100-150cm, and the distance of narrow lines is 40-50cm; the distance of pits is 35-40cm, and three plants are planted in each pit; every two treated seeds per point are sowed into each furrow, the soil is covered while the seeds are sowed, the soil with thickness of one inch is covered and treaded, and 5700-6700 plants are reserved per mou.

Description

technical field [0001] The invention relates to a high-yield cultivation method of corn, in particular to a high-yield corn dense planting cultivation method. 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 is of great practical significance for increasing farmers' income and 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 corn in my country, which requires a large amount of imports 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 sown area of...
