A high-yield planting method for preventing and controlling corn stalk rot in a semi-arid area

Abstract

The invention discloses a high-yield planting method for preventing and treating corn stalk rot in a semi-arid area, and belongs to the technical field of agricultural planting and cultivation. It includes the steps of land selection and preparation, seed selection, seed treatment, ridge making, base fertilizer application, seeding and drip irrigation, weeding and mulching, top dressing, field management, stem rot prevention and harvesting. The invention solves the problem that the full amount of straw returning to the field affects the emergence rate of corn sowing in the second year. After the corn seeds are treated, the emergence rate can be increased by more than 5%, and the straw returning to the field in the second year is not affected; the invention prevents and treats corn The stem rot method has achieved more than 70% control effect on corn stem rot; more than 40% of corn water has been saved, and the yield of corn has increased to 800‑1000 kg per hectare; the unfavorable factors caused by the ecological environment to agricultural production have been overcome, and the traditional The agricultural production mode increases the unit output, realizes the increase in production and efficiency, and has the functions of reducing soil wind erosion, protecting the environment, and improving the ability of crops to resist drought and stabilize production.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting and cultivation, and more specifically relates to a high-yield planting method for preventing and treating corn stalk rot in a semi-arid area. Background technique [0002] Northeast China is located in the northernmost part of my country's temperate zone, close to the sub-frigid zone, and has a significant temperate monsoon climate. The west of Jilin Province is the windy and sandy arid area in the east of the Horqin Grassland. The soil is light chernozem, meadow soil, aeolian sandy soil and saline-alkali soil, with organic matter content below 1.5%, annual precipitation only 300-400mm, and dry and windy spring. Under such natural conditions, it is not conducive to the high and stable yield of dryland crops such as corn. [0003] Straw is an important organic matter resource. Straw contains a lot of organic matter, nitrogen, phosphorus, potassium and trace elements. Returning all ...

Problems solved by technology

[0007] Aiming at the above-mentioned problems in the prior art, the present invention provides a high-yield planting method for preventing and controlling corn stalk rot in semi-arid areas. By decomposing all the straws of the current season, it solves the problem of returning all straws to the field and affecting the emergence of corn seedlings in the second year. rate, after the corn seed is treated by the method of the present invention, its emergence rate can be increased by 6%, and it does not affect the return of straw to the field in the second year; Tested and demonstrated in Qian'an County, Jilin Province, the control effect on corn stalk rot reached 73%.
