Problems solved by technology

However, its degradation process is greatly restricted by factors such as ultraviolet intensity, geographical environment, seasonal climate, and crop varieties, and the degradation rate is difficult to control accurately; in addition, when the field is covered and used, part of the soil cannot be degraded
Photo / biodegradable mulch is based on the addition of starch and other biomass materials to the base material on the basis of photodegradable mulch. Biodegradable mulch has the advantage of being completely degradable, but at the same time it also has difficulties in processing, poor mechanical properties and high cost. lack of
Although the traditional monochromatic mulch can play the role of heat preservation and moisture conservation, it does not have other functions

Abstract

The invention provides a film mulching corn cultivation fully degradable ecological color mulching film for Eastern Inner Mongolia. The film mulching corn cultivation fully degradable ecological colormulching film for Eastern Inner Mongolia comprises a middle black part and transparent parts on both sides of the black part, wherein the black part is composed of 96-66 wt% of polyethylene, 1-4 wt%of biodegradable plastic masterbatch EBP-1680, and black color masterbatch of 3-10 wt% of the total weight of the polyethylene and the biodegradable plastic masterbatch; the transparent parts on bothsides are composed of 95-99 wt% of polyethylene and 1-5% of biodegradable plastic masterbatch EBP-1607. The film mulching corn cultivation fully degradable ecological color mulching film for Eastern Inner Mongolia is highly compatible with drip irrigation under mulching films to effectively avoid early breakage of mulching films due to high-temperature of drip irrigation areas under mulching films, thereby saving labor investment and significantly improving the yield of corn.

Description

technical field [0001] The invention belongs to the technical field of degradable plastics, and in particular relates to a fully degradable ecological color-matched mulch film for corn film-covered cultivation technology in eastern Inner Mongolia. Background technique [0002] Corn is the largest crop in the Inner Mongolia Autonomous Region. In 2015, the sown area of ​​corn in the Inner Mongolia Autonomous Region was further expanded, reaching 51.109 million mu, with an output of 45.02 billion jin. %, accounting for 8.9% and 10% of the national corn planting area and production, ranking third in the country. East Simeng City——Chifeng, Tongliao, Hulunbuir, and Xing'an League represent the overall level of corn in the autonomous region, and have superior resource conditions for corn growth. No matter in terms of soil, climate, or people's planting experience, they are my country's corn planting advantageous production areas. In addition, the Inner Mongolia Autonomous Region h...
