Wheat equal-depth broadcast sowing and under-seed equal-depth fertilizer spreading method

Abstract

The invention provides a wheat equal-depth broadcast sowing and under-seed equal-depth fertilizer spreading method, and relates to the technical field of wheat cultivation and fertilization. The method comprises the following steps: A, performing rotary tillage; B, performing equal-depth fertilizer spreading, spreading fertilizer by using an equal-depth fertilizer spreading device, partially falling turned soil under the fertilizer, partially covering the fertilizer, and spreading the fertilizer to the middle lower part of a rotary tillage layer; C, performing broadcast sowing of wheat, performing broadcast sowing of wheat seeds by using an equal-depth broadcast sowing device, falling the turned soil on the seeds to cover the seeds with the soil, and applying the seeds on the same depth on the middle upper part of the rotary tillage layer; D, finally suppressing. The defects of wheat drilling and broadcast sowing are overcome, the advantages of the drilling and the broadcast sowing are gathered, the utilization rate of the fertilizer and the moisture utilization rate are greatly improved, and the wheat yield per unit area is improved; meanwhile fertilizer input and underground water exploitation are reduced, the crop growth environment is favorably improved and the agricultural ecological environment is favorably protected.

Description

technical field [0001] The invention relates to the technical field of wheat cultivation and fertilization. Background technique [0002] The existing wheat sowing mode is drill sowing or full spread sowing. The seeds of drill sowing are concentrated in the row, and the wheat seedlings are clustered together to grow tall and vigorous, and the wheat seedlings are slender; the competition for water and fertilizer in the individual thinning stage has a greater impact on wheat tillering and ear formation. large, which directly limits the potential of crop production. The yield of wheat was significantly increased by full-width sowing, but there was no suitable space for field work in the wheat field during the growth period and it was difficult to plant the next stubble corn. The existing planting mode is that the fertilizer is sprinkled on the surface and stirred by rotary tillage, and the depth is inconsistent; only a little fertilizer under the seed is absorbed by the crop, ...

Problems solved by technology

[0002] The existing wheat sowing mode is drill sowing or full spread sowing. The seeds of drill sowing are concentrated in the row, and the wheat seedlings are clustered together to grow tall and vigorous, and the wheat seedlings are slender; the competition for water and fertilizer in the individual thinning stage has a greater impact on wheat tillering and ear formation. large, which directly limits the potential of crop production

The wheat yield is significantly increased by full-width sowing, but there is no field work space suitable for the growing period in the wheat field and it is difficult to plant the next stubble corn

The existing planting mode is that the fertilizer is sprinkled on the surface and stirred by rotary tillage, and the depth is inconsistent; only a little fertilizer under the seed is absorbed by the crop, and all the fertilizer above the seed and between the two rows of the drill is wasted, and the wasted fertilizer stays in the soil and groundwater, causing soil and groundwater pollution
