[0002] With the continuous progress and development of agricultural production in our country, soil biodegradable water film, as one of the important means of production in agricultural production, has played a huge role in improving the growth environment of crops and increasing crop yield. Soil biodegradation currently on the market There are many kinds of water films. For example, the application number is 201010569700.4, which discloses a biodegradable film, which includes a film layer and a nutrient layer. The film layer is mainly made of polyhydrocarbyl fatty acid ester (PHA), thermoplastic starch and auxiliary components. The nutrient layer is made of organic matter and plant fibers, and the inner side of the mulch layer is provided with a nutrient layer, and the two are combined into one, which can be degraded into water, carbon dioxide and organic matter by several aquatic bacteria, will not pollute the environment, and can Reduce water evaporation, improve water utilization rate, and then improve the survival rate of crops. At the same time, the biodegradable film can improve the soil, increase soil fertility, and effectively increase the yield of crops in the vast western arid area, but the soil biodegradable water film cannot solve the problem. , how to prevent pests and microorganisms from invading crops, how to timely adjust the color light required for crop growth according to the needs of crop growth, and how to monitor the temperature and humidity of the crop growth environment in real time
