Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, in particular to a tool for loosening the edge of mulch film of crops under mulch cultivation. Background Art

[0002] Covering tobacco fields with mulch is an important technology in the standardized production of tobacco leaves. In the early stage of tobacco leaf growth, covering tobacco fields with mulch can increase ground temperature, retain water and fertilizer, prevent low temperature frost damage and early flowering, and promote early growth and rapid development of tobacco seedlings after transplanting, with obvious effects of increasing production, quality and efficiency. However, if the film is not removed in the later stage of tobacco plant growth, there will be a second peak of fertilizer absorption, which will lead to premature aging of tobacco plants, poor lodging resistance and stress resistance, aggravation of diseases and insect pests, excessive nicotine content in tobacco leaves, imbalance in the proportion of chemical components, and reduced quality of tobacco leaves. Therefore, the mulch should be removed in time 30-35 days after transplanting tobacco plants to improve soil permeability, increase the area of ​​soil receiving rainfall, and allow the root zone to receive more rain water. The aerial roots produced before the film is removed can be fully combined with the soil to expand the root system's absorption area of ​​soil nutrients, thereby promoting early growth and rapid development of tobacco plants and promoting normal growth of tobacco plants.
