Problems solved by technology

The principle of photodegradable mulch is to introduce photosensitizing groups or add photosensitizing substances into high molecular polymers to cause photochemical reactions after absorbing ultraviolet light from the sun, so that macromolecular chains are broken into low molecular weight compounds. , but its degradation process is greatly restricted by factors such as ultraviolet intensity, geographical environment, seasonal climate, crop varieties, etc., 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

Abstract

The invention provides an ecological degradation mulching film for rice in Heilongjiang regions. The ecological degradation mulching film is prepared from 94 wt%-98 wt% of polyethylene and 2 wt%-6 wt%of ecological degradation plastic master batch EBP-1604. According to the invention, a proper quantity of ecological degradation plastic master batch EBP-1604 is added into the polyethylene, so thatthe obtained mulching film is degradable, can be suitable for the induction period of the growth and development of rice crops in the Heilongjiang regions, can meet the thermal insulation and soil moisture conservation requirements of a necessary coverage period during rice growth and development, is favorable for the growth and development of the rice, improves crop yields, and reduces field operation steps. It is indicated, by an experiment result, that the ecological degradation mulching film provided by the invention is used for rice planted in the Heilongjiang regions, can be completely degraded, and can improve rice yields.

Description

technical field [0001] The invention belongs to the technical field of degradable plastics, and in particular relates to an ecologically degradable mulch film for rice in Heilongjiang area. Background technique [0002] Heilongjiang Province is the northernmost province in China and belongs to the high-latitude continental monsoon climate. There are four distinct seasons, with long, cold winters and short, hot summers. Due to the alternation of winter and summer monsoons in spring and autumn, the climate is changeable. In spring, it is very windy, with little precipitation, and it is prone to drought; in autumn, the temperature drops sharply, and there is often frost damage. Heilongjiang Province is the province with the lowest temperature in the country, with an annual average temperature of 2.6°C. Precipitation shows obvious monsoon characteristics, with an average annual precipitation of 515.3 mm. Affected by the southeast monsoon in summer, the precipitation is abunda...
