The no-tillage live-sowing technology of summer corn mainly has the following advantages. First, to reduce farm consumption time and strive for agriculture, especially in areas with insufficient heat resources, no-till direct seeding can effectively extend the growth time of summer corn. The second is to help improve the sowing quality and seedling uniformity, mechanical sowing can make the depth of sowing consistent with the cover, seedlings and neat emergence. The third is to facilitate mechanized operations and improve labor efficiency. Fourth, returning straw to soil can increase soil fertility. Fifth, wheat straw and stubble cover can reduce soil moisture evaporation. Sixth, the reduction of ploughing operations is beneficial to the protection of the environment, and the reduction in soil erosion caused by the reduction in ploughing operations can reduce the environmental pollution caused by straw burning. Seventhly, a small amount of seed fertilizer can be applied while sowing, which will help improve the quality of seedlings. Eighth, in areas prone to budding, early sowing may avoid or reduce the harm of buds. With the popularization and popularization of the wheat harvesting machinery and corn planting machinery in the Huang-Huai-Hai region of China, the area of ​​no-tillage sowing of summer maize will become larger and larger.
ETR has independently developed an integrated vacuum pump unit composed of a water-ring vacuum pump, a gas-water separator, a vacuum solenoid valve, pipe fittings and an electrical control system. It is a simple, safe and reliable device that continuously serves the wards all day long, without occupying the ward space. The negative pressure is sourced from the vacuum pump unit.
