Abstract
The present invention provides a kind of Biodegradable mulch, is made up of starch, polyvinyl alcohol, cellulose, plasticizer, processing aid, and it is as follows that it is formulated constituent：40 60 parts of starch, 20 40 parts of polyvinyl alcohol, 7 10 parts of cellulose, 37 parts of plasticizer, 34 parts of processing aid, the plasticizer are glycerine and ethylene glycol mixture, and it is 12 that it, which is matched,:35, the starch is one kind in cornstarch, wheaten starch, farina, and the cellulose is one kind in sugarcane, stalk.The present invention can be degradable into carbon dioxide and water by microorganism after usage, does not have residual, reduces environmental pollution, improves the reliability of agricultural sustainable development.
Description
Technical field
The present invention relates to a kind of agricultural film, and in particular to a kind of Biodegradable mulch.
Background technology
The wide hair application of agricultural film soverlay technique, high degree promotes the development of agricultural, but ecological environment is made simultaneously
Into greatly " white pollution ", the agricultural film fragment remained in soil can also influence the yield of crop, therefore, can after use
Turned into the research direction of agricultural development from now on by the degradable environment-friendly type degradable agricultural film of microorganism.
The content of the invention
In order to solve the above-mentioned technical problem the present invention provides a kind of Biodegradable mulch, can resolve into two completely by microorganism
Carbonoxide and water, the agricultural film pollution on the environment after use is prevented.
The technical scheme is that：A kind of Biodegradable mulch, by starch, polyvinyl alcohol, cellulose, plasticizer, plus
Work auxiliary agent forms, and it is as follows that it is formulated constituent：Starch 40-60 parts, polyvinyl alcohol 20-40 parts, cellulose 7-10 parts, plasticizer
3-7 parts, processing aid 3-4 parts.
Further, the plasticizer is glycerine and ethylene glycol mixture, and its proportioning is 1-2:3-5.
Further, the starch is one kind in cornstarch, wheaten starch, farina.
Further, the cellulose is one kind in sugarcane, stalk.
Further, the formula constituent is：50 parts of starch, 35 parts of polyvinyl alcohol, 8 parts of cellulose, plasticizer 4
Part, 3 parts of processing aid.
Further, the formula constituent is：55 parts of starch, 30 parts of polyvinyl alcohol, 7 parts of cellulose, plasticizer 3
Part, 4 parts of processing aid.
The beneficial effects of the invention are as follows：The present invention can after usage by microorganism it is degradable into carbon dioxide and
Water, residual is not had, reduces environmental pollution, improve the reliability of agricultural sustainable development.
Embodiment
Clearly complete description is done to the present invention below, so that those skilled in the art need not make creativeness
