A six-row inter-row seeder

technical field

The utility model belongs to the technical field of agricultural machinery, in particular to a six-row inter-row seeder.

Background technique

Corn, wheat and rice are also known as the three major food crops in the world. It has a long history of planting in my country. Because it is not only a high-yield and stable-yield food crop, but also an important raw material for non-staple food, medicine and chemical industry, and an indispensable part for the development of animal husbandry. High-quality feed has a wide range of uses from grain to straw and bracts. Therefore, in my country, the planting area is vast and widely distributed. According to statistics, the national corn planting area is about 27 million hectares.

The traditional planting method of dryland corn in northern my country is to return the straw to the field after harvest in autumn or move it out of the cultivated land and then turn it over, harrow and prepare the land in spring, prepare the seed bed, and then sow. During the whole operation process, the soil is stirred many times, the soil moisture loss is serious, the number of times the machine enters the ground is high, the energy consumption is high, and the soil is compacted. Therefore, it is very necessary to promote no-tillage technology. Its main feature is to cover the ground with straw and stubble of crops to reduce surface runoff of rainwater and water evaporation, and improve the utilization rate of rainwater; it breaks the bottom of the plow through deep loosening, which is conducive to the infiltration of rainwater and the growth of crop root systems, and the establishment of groundwater Drought and waterlogging in reservoirs; straw rots to form a large amount of organic matter, increasing soil fertility, improving soil aggregate structure, water storage and moisture conservation; using no-tillage and less-tillage techniques, less soil movement and moisture loss, reducing damage to the land plow layer; reducing production costs , protect the environment, and promote the sustainable and stable development of agriculture. There is no doubt that the promotion and application of no-tillage precision seeders has become an important topic in the promotion of agricultural machinery in my country.
