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
The present invention relates to a kind of degradable weeding film and application thereof for tealeaves cuttage nursery.
Background technology
Aspect the tealeaves cutting propagation, the harm of weeds causes the decline of plant percent and the increase of production cost.The cost of artificial weeding occupies very high ratio, and simultaneously, easily loosening seedling root reduces survival rate and the outplanting rate of nursery stock greatly in the weeding process.Although general thin covering method of the prior art can be controlled weed growth, because its airtight, fluid-tight shortcoming causes it that coverage is produced high temperature, the pernicious effect of high humidity, have a strong impact on growth and the survival of plant.
Weeding film of the prior art has the mulch film that cooperates weed killer herbicide to use, degradable weeding film is also arranged, such as Chinese patent ZL200910073977.5, ZL201110262952.7, ZL200910237467.7 etc., these technical schemes are comparatively complicated, in general, for when suppressing weed growth, avoiding the effect of high temperature, high humidity effect aspect to seem not ideal enough.
Summary of the invention
For addressing the above problem, the invention provides a kind of degradable weeding film and application thereof for tealeaves cuttage nursery, solved general thin in the prior art and covered that the weeding method is airtight, waterproof to be caused high temperature, high humidity effect and affect the problem of plant growth and survival.
Technical scheme of the present invention is as follows.
A kind of degradable weeding film for tealeaves cuttage nursery, it is characterized in that: by vegetable fiber and the polypropylene fibre that contains black agglomerate according to (0.8～1.2): the ratio of (0.8～1.2) is combined with each other by the heat pressure adhesive technology, and thickness is 50～60g/m
2
Described vegetable fiber is 1:1 with the ratio that contains the polypropylene fibre of black agglomerate.
The shading rate of weeding film of the present invention is 85%～90%.
A kind of degradable weeding film for tealeaves cuttage nursery is used for tealeaves cuttage nursery and covers the application that suppresses weed growth on the seedbed and promote the tea shoot growth.
Compared with prior art, beneficial effect of the present invention: weeding film of the present invention has the effect of lucifuge, ventilative, permeable, insulation, moisturizing, can degrade within 12 months in soil, does not pollute; Be applied to tealeaves cuttage nursery, namely directly overlay on the seedbed of tealeaves cuttage, utilize the interception of its composite fibre can suppress the growth of weeds, utilize its permeable effect to water for the nursery at any time, because the effect of its heat and moisture preserving can promote again the optimum growth of tea shoot, add the gas permeability that it is good, avoided high temperature, high humidity effect.Use weeding film of the present invention that weeding is carried out in tealeaves cuttage nursery, also can greatly reduce the artificial weeding cost, can also improve planting or the survival rate of breeding, outplanting rate simultaneously.
