Method for manufacturing slurry-processed multifunction organic environmental-protection flaky mulching film

Abstract

The invention discloses a method for manufacturing a slurry-processed multifunction organic environmental-protection flaky mulching film. In the method, the waste stems, peduncles, pulverized powders, leaves and the like of plants or crops are used as raw materials, and a machining process can be effectively controlled according to the mechanical strength, the light transmittance, the ventilation, the heat preservation, the water retention or other particular effects (such as adding a sterilization disinfectant, an extra-nutrition element, a controlled release fertilizer and the like) demanded by the mulching film, and the specific machining process can be chosen according to the actual situation. The slurry-processed flaky mulching film manufactured by the method for manufacturing the novel slurry-processed multifunction organic environmental-protection flaky mulching film has the advantage of economic and environmental protection characteristics, and has the characteristics of rich sources of the raw materials, low cost, biodegradability, soil improvement, time saving, labor saving, high controllability and the like.

Description

technical field [0001] The technology relates to a method for making multi-functional organic environmental-friendly thin mulch film by thick slurry method. Background technique [0002] Film mulching has brought changes in agricultural production methods and a leap in agricultural productivity due to its functions of increasing temperature, water retention, adjusting fertilizer, and suppressing weeds. It has been widely used in the production of food crops, economic crops, nurseries, flowers, vegetables, etc. middle. Since China introduced it in 1978, the area covered by plastic film has gradually expanded. As of 2005, it has reached 959,000 tons, and the application area has reached 13.53 million hm2. It is the country with the largest cultivation area covered by plastic film in the world. However, since the current mulch materials in China are polyethylene (PE) and polyvinyl chloride (PVC), which have a large molecular weight and are difficult to degrade under natural co...
