The invention also relates to an automatic profiling paddy row pushing type weeding device group and an automatic profiling paddy paddy paddy row pushing type weeding method. The invention improves the weeding effect and avoids root damage, and belongs to the field of intelligent agricultural machinery.

Description

technical field [0001] The invention relates to the field of intelligent agricultural machinery, in particular to an automatic profiling paddy inter-row pushing type weeding device, to an automatic profiling paddy inter-row pushing type weeding device group, to an automatic profiling paddy paddy Inter-row push-and-push weeding method. Background technique [0002] Rice is one of the main food crops in my country, and its planting area accounts for about 1 / 5 of the world's total. Weeds in paddy fields compete with rice for growth space, air, sunlight and nutrients, which is one of the main factors affecting rice yield. The rice yield loss rate caused by weeds in my country is more than 15% every year. Therefore, weed control is of great significance to improve rice yield. At present, the commonly used weeding method in our country is chemical weeding, which saves time, low cost, low labor intensity and strong implementation, but its pesticide utilization rate is low, serio...
