No-tillage field-returning seeder for straws

Abstract

The invention relates to a no-tillage field-returning seeder for straws. The seeder comprises a walking tractor, a grass cutting device and a seeding device which are installed behind the walking tractor as well as an opener which is installed in front of the walking tractor. The innovation point is that a planting method of whole surface field-returning no-tillage seeding and ditching to cover seeds and grass of straws is adopted, so that granular structures and capillary water supply systems of a land are not damaged; the straws returned to the field are distributed on two sides of a seeding belt; the straws not only do not affect germination and growth of seeds, but also have the effects of insulating, moisturizing, antifreezing and weed growth preventing on the surface. In particular, winter wheat in drought and cold winter is prevented from being frozen and frozen to death. The method is a novel planting method for no-tillage field-returning seeding of straws.

Description

Technical field [0001] The invention relates to a planter, in particular to a planter capable of planting seeds when crop straws are returned to the field without tillage. Background technique [0002] Crop stalks have been a major fuel for rural farmers since ancient times. With the construction of a new socialist countryside, Chinese farmers have also used electricity and gas like urban residents. Straws are no longer used as fuel, but are used by farmers in the field. Burn the fire.

AI Technical Summary

Problems solved by technology

The smog produced by the burning of such a large amount of straw not only seriously pollutes the environment, but also often causes many traffic accidents, and sometimes even the planes at the airport cannot see the runway landing clearly.

For this reason, governments at all levels have issued three orders and five orders to strictly prohibit the burning of straw in recent years, and on the other hand, they have increased investment in research and development of crop straw returning machinery to control the phenomenon of straw burning, but so far all straw returning machinery have failed. It is nothing more than crushing the straw and plowing it into the top. This is not a big problem for crops such as rice and other crops sown after the summer harvest, but there are many problems for crops such as winter wheat sown after the autumn harvest. After fielding, the original aggregate structure and capillary water absorption system of the soil are destroyed, and in areas with little rain and severe cold, large areas of winter wheat often freeze to death.

For this reason, it is a big problem that has not been well solved for many years to develop a kind of machinery that can ensure that the straw returning to the field is beneficial to the growth of crops, especially the straw returning machinery that can adapt to the growth of crops planted in autumn and winter such as winter wheat.
