A wheat deep loosening rotary tillage layered fertilization and belt spreader

Abstract

The invention provides a deep scarification, rotary tillage and layered fertilization zoning seed broadcaster for wheat, and relates to the technical field of wheat seeding machinery. Deep scarification layered deep fertilization device is arranged in front of rotary tillage devices. Equal-depth fertilizer spreading devices are arranged behind the rotary tillage devices. Equal-depth seed spreading devices are arranged behind the equal-depth fertilizer spreading devices. Repression devices are arranged behind the equal-depth fertilizer spreading devices. Fertilizer applied through the deep scarification layered fertilization devices are applied under the rotary tillage layer in a layered mode. Fertilizer applied through the equal-depth fertilizer spreading devices is applied in the lower middle portion in the rotary tillage layer. Seeds spread through the equal-depth seed spreading devices are located on the upper portion inside the rotary tillage layer. Fertilization and seed spreading are conducted in all rotary tillage belts in a layered mode. The deep scarification, rotary tillage and layered fertilization zoning seed broadcaster can complete deep scarification, deep-layer deep slow release fertilizer applying, equal-depth base fertilizer spreading, equal-depth seed spreading and sowing, earthing, repression and other work at a time when entering the ground; the fertilizer utilization rate can be effectively increased, the growth of wheat at the seedling stage and the later stage can be promoted, the pollution of residual fertilizer on soil and underground water can be reduced, the production and income increase of wheat can be promoted, the top dressing at the later stage can be reduced, energy can be saved, and efficiency can be high.

Description

technical field [0001] The invention relates to the technical field of wheat sowing machinery. Background technique [0002] Most of the existing base fertilizer application methods are to spread the fertilizer on the surface and stir it with rotary tillage, and the fertilizer depth is inconsistent; most of the wheat seeders are drill sowing, with narrow sowing belts, concentrated emergence of seedlings, competition for nutrients between seedlings, and the gap between two ridges. Soil nutrients and water cannot be fully utilized; due to the inconsistent depth of fertilizers, seeds are sown in drills, only a little fertilizer under the seeds is absorbed by the crops, and the fertilizers above the seeds and between the two rows are all wasted and stagnant in the soil, causing soil and groundwater damage. Pollution, destruction of the ecological environment. [0003] Existing wheat needs rotary tillage before planting, which requires a lot of soil movement and serious soil moi...

[0003] Existing wheat needs rotary tillage before planting, which involves a lot of soil movement and serious soil moisture loss, which is easy to cause water loss, which is contrary to the actual needs of the current water shortage.
