High-yield planting method for preventing and treating corn stem rot in semi-arid regions

Abstract

The invention discloses a high-yield planting method for preventing and treating corn stem rot in semi-arid regions, belonging to the technical field of agricultural planting and culturing. The high-yield planting method comprises the following steps: land selection and preparation, seed selection, seed treatment, ridging, base fertilizer application, seeding, drop irrigation, water feeding, weeding, membrane lamination, top application, field management, corn stem rot prevention, harvesting and the like. According to the high-yield planting method, the problem that the seeding emergence rate of corns in the second year is influenced by the total straw application of straws is solved; by processing corn seeds, the emergence rate can be improved by more than or equal to 5%, and the straw turnover in the second year is not influenced; the preventing and treating effect of the corn stem rot reaches more than or equal to 70%; water is saved by more than or equal to 40%, and the corn yield is increased to be 800-1000 kilograms per hectare; adverse factors caused by the ecological environment to the agricultural production are overcome, the traditional agricultural production mode is changed, the unit yield is increased, the yield and the efficiency are increased, and the effects of reducing wind erosion of soil, protecting the environment and improving the drought resisting capacity and the production stability of crops are achieved.

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 an organic matter content below 1.5%, annual precipitation of only 300-400 mm, 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. Returni...

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 is solved that the full amount of straws is returned to the field, which affects 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%.
