Abstract

The invention belongs to the technical field of manufacturing ground mulching films and particularly relates to a degradable mulching film containing plant fiber degradable filler. The degradable mulching film includes: resin as a mulching film substrate, a degradable master batch that promotes degradation of the mulching film, degradable filler that contains natural plant fiber powders, an antifogging agent, and an additive. The resin is polyvinyl chloride (PVC) or is mixed resin composed of polyethylene (LDPE), linear low density polyethylene (LLDPE) and metallocene polyethylene (mPE). In manufacturing of the degradable mulching film, by means of the plant celluloses such as straw powder, rice hull powder, cottonseed powder and the like, conditions for reproduction of microorganisms in soil are created, thus achieving the objects of turning waste into resources by straw returning. These natural plant fibers have the effect of promoting degradation of the mulching film.

Description

technical field

[0001] The invention mainly belongs to the technical field of ground covering film manufacture, and in particular relates to a degradable ground film containing plant fiber degradable filler. Background technique

[0002] Ground-covering film agriculture technology has become a new cultivation technology developed in my country in the 1970s. The ground covering film agricultural technology is to cover the transparent and colored (black, white, green) film with a thickness of 0.01‐0.02mm on the surface of the ground for cultivation. It is the most simple and feasible form of protected land. Temperature, promote root development, thereby increasing crop yield and output value. In addition, plastic film mulching also has effective functions such as water conservation, water saving, weeding, promotion of organic fertilizer decomposition, and keeping soil loose (preventing soil compaction).

[0003] The traditional plastic film has the characteristics of high str...
