Abstract

The invention discloses a PP grass preventing ground cloth with a long-acting anti-aging function. The PP grass preventing ground cloth is prepared from, by mass, 85%-90% of polypropylene, 4%-5% of color masterbatch, 3%-5% of an anti-aging aid and 3%-5% of filling masterbatch. According to the PP grass preventing ground cloth, the formula design is optimized and improved, the anti-aging performance of the grass preventing ground cloth is greatly improved, the grass preventing ground cloth can be used for 5-10 years and has the advantage of being beneficial for many years after being put into use one time, and in addition, the grass preventing ground cloth has good shading, ventilating, water seepage and heat preservation performance.

Description

technical field [0001] The invention relates to the technical fields of agriculture and gardening, in particular to a PP grass-proof ground cloth with long-acting anti-aging function. Background technique [0002] In the current agricultural planting of crops, weeds are easy to grow in the gap area outside the planted crops and the distance between fruit trees, which affects the attraction and growth of crop fertilizer efficiency. Green planting is now advocated, and manual weeding is required at least four times a year, which increases labor costs. input. [0003] However, the use of the existing agricultural mulch film has poor sunshade effect, impermeability, and airtightness, which affects soil respiration and prevents the ground from going up and down, which may cause plant roots to rot and affect yields; Human body, crops, soil, etc. are all harmed and affected. Agricultural membranes have a short service life, generally within one year, and a large amount of manual ...
