Abstract
A kind of Environment protection mulch film and compound method belong to product for agriculture.In order to reach the purpose of environmental protection, it is bed material that the present invention adopts with paper pulp and peat, is the Environment protection mulch film of lining preparation with paper pulp.Advantage of the present invention is: (1) reduces white pollution, easily decomposes, and can increase the soil organism, increases soil fertility; (2) prevent weed growth; (3) compare with open country and can improve the soil moisture and humidity; (4) widespread use field crop, cash crop etc.
Description
Technical field:
The invention belongs to product for agriculture, particularly relate to a kind of preparation of agricultural mulching.
Background technology:
At present, the most of mulch films that use all are synthetic polymers both at home and abroad, as polyethylene (PE) and polyvinyl chloride (PVC) mulch film.The mulch film that uses these materials has also brought severe contamination to agricultural environment when bringing certain economic benefit to agricultural.Mainly be can not to decompose voluntarily and disappear in soil, the fragment that remains in a large number in the soil causes Soil structure to destroy, and has brought very big difficulty for farming and sowing.The workload that reclaims relic is big, cost is high (can reach 250---500 dollar/hectare abroad, China labor force is relatively low, does not have concrete statistics, but also is a no small expenditure).Residual film problem is serious day by day, has greatly restricted further applying and developing of mulch film.Therefore, the research of degradable agricultural mulching, exploitation have all caused great concern at home and abroad.
And domestic and international research work reduces following four aspects:
(1) degraded agricultural mulching adds photosensitizers and promotor and makes in resin;
(2) biological degradability agricultural mulching comprises and adds starch degradation mulch film etc.;
(3) degradable by light or organisms mulch film;
(4) plant fiber mulch.
More than 4 class degradability agricultural mulchings through research and development for many years, obtained some achievements, but also had some problems:
1, add the starch degradable mulch film, starch content is few in its material, has only about 20%, thereby does not reach tangible biological degradation.In addition, the expert who has thinks that this mulch film can only be the decomposition of starch, and residual polyolefin film still exists with a kind of low intensive vesicular structure form under action of microorganisms.Thereby be a kind of incomplete Biodegradable film.
2, according to Alberllsson and the nearly 10 years result of study of Corlsson, though the polyethylene after the degraded can be by bacterial degradation, that decomposes is chronic.From biological degradation taking place, need the time in year surplus in the of 50 to entering the ecosystem fully.
3, photodegradation film only can solve the surface of ploughing and go up the pollution problem that residual film accumulation is caused, and the mulch film that is embedded in the soil then can't be degraded.
4, be the mulch film of raw material with the vegetable fibre, the microorganism in the soil just can be decomposed it.And degradation production can be used as organic fertilizer, increases soil fertility, meets " ecological agriculture ".But problem that it exists at present: the one, guaranteeing under its biodegradable prerequisite how to select the plant fiber material and the auxiliary agent that suit, make it the index that reaches similar with plastic film; The 2nd, be the mulch film of raw material with the vegetable fibre, because manufacturing and raw materials cost are higher, be difficult to promote.
Technology contents:
In order to address the above problem, the invention provides a kind of can in soil surface or soil, the degraded fully, become organism, and manufacturing and the lower Environment protection mulch film of raw materials cost.
Prescription of the present invention is: (weight part ratio)
