Background technique

Rotary tillage can make the soil loose and broken, which is beneficial to the ditching and soil covering operation during sowing, which is beneficial to the germination of seeds and the growth of seedlings, and can create conditions for full and strong seedlings and good growth of plants.

Excellent population structure is conducive to ventilation and light transmission in the canopy of wheat populations, making individual growth and development robust, and promoting the increase of wheat yield. Drill sowing is the main method in traditional wheat production, with uneven seed spacing and large seeding volume, which is not conducive to high yield. Wheat wide seedling belt precision sowing can make the seeds evenly distributed in the field, forming an excellent population structure, each plant can obtain enough nutrient area and space, absorb water and fertilizer to the maximum, effectively carry out tillering, and increase the number of ears of wheat, Large ears and full grains can increase production and income, reduce the amount of sowing and reduce operating costs.

The separate application of seed fertilizer can reduce the damage of fertilizer to seeds, promote the growth of crops at the seedling stage, and help increase production and income. When sowing in a wide seedling belt, compared with side fertilization, lower fertilization in the seedling belt can avoid the disadvantages of uneven nutrient absorption of wheat seedlings, large growth differences, and low yield of weak seedlings, and is more conducive to uniform absorption of seeds on the seedling belt. Nutrients are conducive to stable and increased production.

At present, there are no reports of machines capable of one-time rotary tillage, lower fertilization with wide seedling belts, and precision planting with wide seedling belts.
