Abstract

The invention discloses an environment-friendly type water-saving agricultural mulching film and a preparation method for the same, aiming at solving the problems of bad soil moisture preservation, heat preservation, water preservation and fertilizer preservation effects on crops, and short service life, of the existing environment-friendly type water-saving agricultural mulching film. The environment-friendly type water-saving agricultural mulching film is made from the raw materials in the following percentage by weight: 2-5% of water-preserving resin master batch, 1-3% of heat-preserving auxiliary, 3-6% of EVA (ethylene vinyl-acetate copolymer) resin, 5-12% of metallocene, 3-6% of weather-resistant agent master batch, 62-80% of linear low-density polyethylene particles, and 6-9% of high-density polyethylene particles. The soil moisture preservation, heat preservation, water preservation and fertilizer preservation effects of the agricultural mulching film disclosed by the invention on crops are improved by 50% compared with common mulching films, the service life of the agricultural mulching film achieves more than 23 months, and the agricultural mulching film can be mechanically and completely recovered after being used, so as to be reutilized, thus eliminating 'white pollution', and protecting ecological environment.

Description

technical field [0001] The invention relates to an agricultural plastic film, in particular to an environment-friendly water-saving agricultural plastic film. Background technique [0002] my country is a traditional agricultural country. In recent years, with the rapid development of high-efficiency water-saving agriculture, facility agriculture, and dry farming, the demand for environmentally friendly water-saving agricultural mulch is increasing. However, due to the increasingly prominent problem of residual film and polluted soil, the comprehensive promotion and application of plastic film mulching cultivation technology has been greatly restricted. In addition, the traditional environment-friendly water-saving agricultural mulch film has poor effects on crop moisture conservation, heat preservation, water retention, and fertilizer retention, and its service life is short. Contents of the invention [0003] The purpose of the present invention is to provide an environ...
