Abstract

The invention discloses a device for cutting auxiliary roots of wheat, which comprises a shovel handle and is characterized in that the lower side of the shovel handle is connected with a shovel tip, the upper side of the shovel tip is provided with a front cutting edge, and the lower side is provided with a rear cutting edge, and the front cutting edge and the rear cutting edge are vertical to the same plane. The device can effectively cut the partial auxiliary roots between every two wheat lines, has a certain loosening function, little advancing resistance and high working efficiency, needs not to dig, keeps the upper soil layer and the lower soil layer orderly to reduce the dispersion of soil moisture content, and can play the role of removing grass.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a device for cutting off lateral roots of winter wheat before overwintering or during the greening stage. Background technique [0002] Wheat is one of the important food crops in my country. With the improvement of people's living standards and the continuous reduction of arable land, the status of high-quality and high-yield wheat has become more and more important. Wheat research experts have found in the study of high-yield production practices of wheat: cutting off or damaging the lateral roots of wheat in the early stage will not only not reduce the yield of wheat, but will have a positive effect on yield. This is because intertillage pruning has a promoting and controlling effect on the root system. The root cutting of winter wheat seedlings damaged part of the root system of the plant, that is, it had an inhibitory effect on the root mass and root growth...
