A kind of black weeding non-woven fabric and its production process

Abstract

The invention relates to the field of agriculture, in particular to a black weeding non-woven fabric and a production process thereof. The production process includes the steps of material sucking, melting and extruding, stretching, lapping recombination, hot rolling recombination, cooling shaping and rolling and slitting. The process is simple, the production efficiency is high, and the processedblack weeding non-woven fabric is good in breathability, capable of being naturally degraded, good in weeding effect and low in cost.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a black weed-killing non-woven fabric and a production process thereof. Background technique [0002] With the development of science and technology, agriculture is gradually rising. Many farmers take planting as a profession and increase their income by planting various plants and vegetables. As we all know, there will be many weeds growing in the fields, and weeds can easily absorb nutrients and water in the soil. , and compete with the target plants for light and ground space, causing great harm to the growth of the target plants, and the tenacious vitality of the weeds and shrubs themselves and their strong adaptability to adverse climatic conditions require manual weeding or spraying herbicides 2 to 4 times a year, resulting in high labor costs and soil erosion. At the same time, herbicides cause serious pollution to soil and air. In order to improve work efficiency and increase ...

As we all know, there will be many weeds growing in the fields, and weeds can easily absorb nutrients and water in the soil. , and compete with the target plants for light and ground space, causing great harm to the growth of the target plants, and the tenacious vitality of the weeds and shrubs themselves and their strong adaptability to adverse climatic conditions require manual weeding or spraying herbicides 2 to 4 times a year, resulting in high labor costs and soil erosion. At the same time, herbicides cause serious pollution to soil and air

In order to improve work efficiency and increase the output of crops, many farmers use black PE mulch film or transparent film plus herbicide to cover weeds. However, the mulch film not only has poor air permeability, is non-degradable, has poor weeding effect, and affects the growth of crops. Transparent film plus The cost of herbicides is high, and the effect is often not up to the ideal value
