Abstract

The invention discloses a biodegradable agricultural plastic mulching film loaded with sophocarpidine, which is characterized by being prepared by, firstly, extracting and separating sophocarpidine by a joint technology of ultrasound extraction and microwave extraction and trichloromethane extraction; under the catalyst of ammonium persulfate, grafting acrylic ester on starch; at last, using starch and acrylic ester grafted starch as film-forming agent through and flow-casting and film-forming method, and acquiring the biodegradable agricultural plastic mulching film loaded with sophocarpidine. The biodegradable agricultural plastic mulching film loaded with sophocarpidine can kill insects in the soil and well keep soil moisture; the residual mulching film can be completely degraded and cannot pollute environment; moreover, the cost is low.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a biodegradable matrine-loaded agricultural mulch film and a preparation method thereof. Background technique [0002] Among agricultural pollution sources, pesticide pollution is the most serious aspect. Extensive use of highly toxic and high-residue broad-spectrum chemical pesticides not only causes serious pesticide content in farmland and agricultural products to exceed the standard, but also often causes human and animal poisoning incidents, threatening people's lives and health. In order to fundamentally change this situation, it is necessary to use high-efficiency, low-toxic or non-toxic, low-residue or no-residue botanical pesticides. Many types of plants contain components that kill diseases and insect pests, and after industrial extraction, they can be used as pesticides, that is, botanical pesticides. The vast majority of plant pesticides are low-toxic, do not ...
