Problems solved by technology

The publication number is CN102311630, and the name is fully biodegradable aliphatic carbonate mulch and its preparation method. The raw materials used are fully biodegradable materials, which can replace traditional mulch and can achieve full biodegradation, but completely biodegradable fat The carbonic acid ester technology is relatively immature, the cost is high, and the mulch film produced with this raw material as the main base material has poor heat resistance

Abstract

The invention discloses a completely-biodegradable mulching film material which contains one kind or several kinds of compounds which are selected from a group consisting of polyhydroxy alkanoates, polylactic acid, poly(butylene adipate-co-terephthalate), poly(butylene-scuccinate / adipate) and poly(butylene-scuccinate). By adopting the completely biodegradable mulching film material, the yield of crops can be greatly improved, the mulching film material can be completely biodegradable without residues of a mulching film, and the yield of crops can be continuously increased.

Description

【Technical field】 [0001] The invention relates to a mulch material, in particular to a completely biodegradable mulch material. 【Background technique】 [0002] Since the plastic film mulching cultivation technology was tested, applied and promoted in China, it has become an important technology for increasing agricultural production. However, since most of the current mulch films are polyethylene or polyvinyl chloride mulch films, their stability is extremely high, and the degradation process is quite slow, about 100 years; the fragments remaining in the soil cannot be degraded by soil microorganisms, nor can they be absorbed and utilized by crops. Especially the manufacture of ultra-thin plastic film, although the amount of plastic film per unit area can be relatively reduced and the cost can be reduced, but the thinner the plastic film, the easier it is to break. bring great difficulty. With the extensive use of plastic mulch, the accumulation of residual plastic mulch i...
