Abstract
The invention discloses a degradable weeding film for a tea leaf cutting nursery and an application thereof. The weeding film is formed by compounding plant fibers and polypropylene fibers with black master batches according to the ratio of (0.8-1.2) to (0.8-1.2) through a hot press bonding technology, and the thickness of the weeding film is 50-60 g / m<2>. The weeding film has the effects of sun-shading, breathing, water permeating, heat preservation and moisture preservation, can be degraded in the soil within 12 months, and does not cause pollution; the weeding film is applied to the tea leaf cutting nursery, namely the weeding film directly covers a tea leaf cutting seedbed, the weed growth can be inhibited by utilizing the sun-shading effect of the compound fiber of the weeding film, the nursery can be watered at any time by utilizing the water permeating effect of the weeding film, the benign growth of tea seedlings can be also promoted due to the heat preservation and moisture preservation effects, and the breathability is good, so that the high-temperature and high-moisture effects are avoided.
Description
technical field [0001] The invention relates to a degradable weed-killing film for tea cutting nursery and application thereof. Background technique [0002] In terms of tea cutting propagation, the harm of weeds causes the decline of seedling survival rate and the increase of production cost. The cost of manual weeding occupies a very high proportion. At the same time, it is easy to loosen the root system of seedlings in the process of weeding, which greatly reduces the survival rate and emergence rate of seedlings. Although the common film mulching method in the prior art can control the growth of weeds, due to its airtight and watertight shortcomings, it has a harmful effect of high temperature and high humidity on the coverage area, seriously affecting the growth and survival of plants. [0003] The herbicidal films in the prior art include mulch films used with herbicides and degradable herbicidal films, such as Chinese patents ZL200910073977.5, ZL201110262952.7, ZL200...
