Problems solved by technology

[0003] The base material used in the existing insect trap board is PP or PVC derived from the petrochemical industry. Hang it in the use area; when using it to kill pests, it can avoid pesticide pollution to the environment, but it is mainly made of PP plastic, which is not easy to degrade. The discarded insect traps will still pollute the environment because they are not easy to degrade. It has caused serious secondary pollution to the agricultural ecological environment, and the follow-up treatment is extremely troublesome, which has brought inconvenience to field cleaning; in recent years, the existing insect traps have been used more and more widely, and the number of uses has also increased year by year, causing damage to the agricultural ecological environment more serious

Abstract

The invention discloses a biodegradable insect trapping plate and a preparation method thereof. The insect trapping plate comprises the following components in parts by weight: 40-70 parts of PBAT, 10-40 parts of PLA, 10-40 parts of cellulose, 10-20 parts of starch, 1-15 parts of biodegradable color masterbatch / toner and 2-15 parts of an auxiliary agent. The cellulose and the starch are added intothe biodegradable resin, so that the cost of the biodegradable insect trapping plate is greatly reduced, the popularization is facilitated, the application of the cellulose is expanded, and the economic benefits of the cellulose and the starch are improved; in addition, the biodegradable insect trapping plate can be completely degraded by microorganisms in the nature, finally carbon dioxide, water and minerals are generated, and the environment is not polluted.

Description

technical field [0001] The invention relates to the technical field of agricultural and forestry pest control, in particular to a biodegradable insect trap and a preparation method thereof. Background technique [0002] Small pests such as thrips, whitefly, aphids, and Liriomyza sativae have always been the main pests on vegetables, flowers, and important economic crops. Their tiny individuals, fast reproduction speed, hidden activities, and wide host range are extremely harmful to crops. As an important physical pest control product, the insect trap has been widely used in the monitoring and control of pests in the production of vegetables, flowers, and forest fruits following the concept of green, safe and environmentally friendly plant protection; It effectively reduces the use of chemical pesticides, delays the development of pest resistance, reduces pesticide residues in the environment and in fruits and vegetables, and improves food quality and quality. [0003] The b...
