Seed-fertilizer integrated organic dry farming sowing method for returning whole corn stalks to field

Abstract

The invention discloses a seed-fertilizer integrated organic dry farming sowing method for returning whole corn stalks to the field. The method is implemented by integrating production place environment, seed selection, sowing, intertillage management, watering, foliar fertilizer spraying, pest control, harvesting and production archives, and is characterized in that an agricultural production area which is good in ecological condition, far away from a pollution source and free of mulching film covering and has sustainable production capacity is selected as the production place; the environment quality, the air quality, the irrigation water quality and the soil quality should meet the regulations of NY / T849; and a variety which is subjected to national or provincial approval and suitable for being planted in a local area is selected for seed selection, the quality of seeds meets the regulation of GB4404.1, and coated seeds meet the regulation of GB / T15671. According to the invention, surface soil and sowing soil are ingeniously and separately subjected to rotary tillage, so that straw can be ridged, and the emergence rate of the seeds is increased through soil moisture detection sowing, and the purpose of increasing the yield is achieved; and lodging resistance of the corn can be improved through intertillage ridging, root nutrient absorption is promoted, and the final yield can be increased by 3%-7%.

Description

technical field [0001] The invention belongs to the field of corn planting, and in particular relates to an integrated organic dry-farming sowing method for returning whole corn stalks to the field for planting and fertilizer. Background technique [0002] Corn stalks are rich in trace elements such as carbon, nitrogen, phosphorus, potassium and magnesium. They have high utilization value and are a renewable resource. It is easy to cause soil erosion and even reduce crop production. With the development of our country's economy, people's living standards are improving day by day, and the requirements for quality of life are getting higher and higher. All parts of our country are fully implementing the strategic deployment of the central government on strengthening the construction of ecological civilization. For this reason, the central government issued a special "2019 To solve the problem of straw returning to the field, the Guiding Opinions on the Implementation of the S...

AI Technical Summary

Problems solved by technology

Recycling of straw is limited by the number of breeding plants and only a small part can be recycled, which is far from meeting the requirements of straw residue treatment. Although no-tillage direct seeding solves the problem of straw, but because the straw covers the soil surface and the soil is not rotary plowed, Reduces soil temperature while retaining water, reducing corn yields
