Problems solved by technology

However, in our long-term attention and years of research and development on liquid mulch, we have also found that the above-mentioned liquid mulch preparation method has "complex process flow, more production equipment required, higher manufacturing cost, and light transmission of the product" in actual use. The technical defect of increasing temperature and keeping fertilizer and moisture is poor
So far, we have not seen mature examples and related literature reports on the application of the above-mentioned liquid mulch film in large-scale planting areas.

Abstract

The invention discloses an ecological liquid mulch film for farmland weeding and its preparation method and application method. It is made of konjac flour, industrial gelatin and quicklime as raw materials, crushed and degranulated, measured and bagged to make raw powder and fine materials, and then formulated according to weight. By adding glycerol and water and stirring to make a stock solution and spraying it on the planting ground, a liquid mulch film with good planting ecological performance can be formed. Its film-forming mechanism is: use konjac flour (the main active ingredient is konjac glucomannan) with the biological characteristics of gel film-forming as a polymer film-forming substrate, use glycerol as a plasticizer, and industrial gelatin as a reinforcement The agent can improve the performance of liquid mulch. The invention has the outstanding advantages of rich and cheap raw material sources, low production cost, convenient use, good performance of light transmission, heat preservation, fertilizer and moisture conservation, fast degradation speed, and no environmental pollution. The multi-functional ecological liquid mulch new product has excellent application prospects in vast agricultural planting areas.

Description

technical field [0001] The invention relates to a liquid mulch film, and also relates to its preparation method and use method, belonging to the technical field of agricultural production and soil ecological environment protection, in particular to a farmland weeding ecological liquid mulch film and its preparation method and use method. Background technique [0002] Since the 1980s, a planting and production method using polyethylene plastic mulching cultivation technology has widely emerged in my country's agricultural areas. This plastic film mulching cultivation technology has the functions of increasing temperature, maintaining moisture, maintaining fertility and preventing water evaporation loss. It has a very significant technical effect on promoting the early maturity of crops, improving the quality of varieties, increasing production and income, and is known as another after chemical fertilizers and pesticides. It is the third major technical invention that changes ...
