Problems solved by technology

[0007] However, for a long time, spring maize has been planted earlier and is easily affected by low temperature. At the same time, due to the characteristics of maize production, topdressing is required during the maize development period, which wastes a lot of manpower. For corn production, the cultivation measures of corn must be improved to save time and effort, so a high-yield and high-efficiency corn cultivation method is necessary, but there is no report in the prior art

Embodiment 1

[0016] The corn variety Zhengdan 958 was selected and planted in Shagou Town, Yishui County. 5500kg of pig manure, 15kg of urea, 8kg of potassium chloride, 25kg of superphosphate, and 15kg of urea slow-release fertilizer were applied to each mu of land; Sowing machine, deep loosening 25 cm, breaking the bottom of the plow, increasing soil water storage capacity, reducing water and fertilizer loss; using a 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; Ridge planting adopts the wide and narrow row planting method of one ridge and two rows. When sowing, the ridges are covered with black and white color-matched plastic film to keep heat and moisture. At the same time, no herbicides are used; timely control of corn leaf spot, Corn rust, corn borer, corn aphid; when the lower part of the corn plant turns yellow, the bract leaves are y...

Embodiment 2

[0018] Select the corn variety Tiantai No. 10 and plant it in Sunzu Town, Yinan County. Apply 6000kg of pig manure, 15kg of urea, 9kg of potassium chloride, 26kg of superphosphate, and 16kg of urea slow-release fertilizer per mu of land; machine, deep loosen 30 cm, break the plow bottom layer, increase soil water storage capacity, and reduce water and fertilizer loss; apply 6 layers of fertilizer in the whole growth period to the corn root system through the precision sowing machine, which is conducive to absorption during the whole growth period and reduces leaching; Ridge planting adopts the wide and narrow row planting method of one ridge and two rows. When sowing, the ridge is covered with black and white color-matched plastic film to keep heat and moisture. At the same time, no herbicides are used; timely control of corn leaf spot, corn Rust, corn borer, corn aphid; when the lower part of the corn plant turns yellow, the bract leaves are yellowish-white and loose and dry, ...

Embodiment 3

[0020] The corn variety Danyu 86 was selected and planted in Baoshan Town, Jiaonan City, and 2500kg of chicken manure, 16kg of urea, 8kg of potassium chloride, 25kg of superphosphate, and 15kg of urea slow-release fertilizer were applied per mu of land; a subsoiling full-layer fertilization precision seeder was used , deep loosening 28 cm, breaking the bottom layer of the plow, increasing the water storage capacity of the soil, and reducing water and fertilizer loss; using a 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; ridging For planting, adopt the wide and narrow row planting method of one ridge and two rows. When sowing, cover the ridge with black and white color-matched plastic film to keep heat and moisture. At the same time, no herbicides are used; timely control of corn leaf spot and corn rust , corn borer, and corn aph...

Abstract

The invention discloses a high-yield high-efficiency cultivation method for spring corns in hilly and mountain areas. The method includes the steps of selecting drought-resistant barren corn varieties, applying enough base fertilizers, applying organic and inorganic fertilizers, applying fertilizers and slow release fertilizers, turning up soil deeply, performing multi-layer fertilizing, covering color-matching mulching films, controlling pests and harvesting in due time. According to the method, the spring corns are planted in hilly and mountain areas, the early spring freeze injury is reduced through covering of mulching films, the topdressing link is reduced through additionally applying organic fertilizers and slow release fertilizers, labor is saved, the yield per mu can reach above 650kg, and economic and social benefits are improved obviously.

Description

technical field [0001] The invention relates to a high-yield and high-efficiency cultivation method for spring maize in hilly and mountainous areas, and belongs to the technical field of maize cultivation. Background technique [0002] Corn is an important food crop and feed crop in the world and in my country. In 2012, the national corn output was 208.12 million tons, an increase of 15.34 million tons, and the corn output exceeded the rice output by 3.83 million tons, becoming my country's largest food crop. Significance. [0003] One is the need to ensure national food security. National food security mainly includes ration security, feed and processed grain security. Grain security is mainly to ensure the stable development of rice and wheat production. The safety of feed processing grains mainly ensures the stable development of corn and potatoes. Driven by the growth of animal husbandry and industrial demand, my country's current corn consumption is growing rapidly, ...
