The results showed that the early stage of Capsicum frutescens growth （0~52 days after film mulching） was the main period of temperature increase by mulching, and plastic mulching planting mainly increased the soil temperature of 0~5 cm and 5~10 cm soil layers during this period. Among them, the warming effect of PM5 was similar to that of PE, with an average temperature increase of over 2 ℃ in the 5~10 cm and 10~15 cm soil layers compared to CK （open field planting）. The height of chilli plants grew significantly from 24 to 47 d after mulching, with an average increase of about 20.28 cm. After 39 days of film mulching, PM5 was increased by approximately 8.2 cm compared to CK; there were significant differences in the chlorophyll SPAD of Capsicum frutescens with different film mulching treatments after 23 days of film mulching, with PM5 and PE significantly higher than CK, increased by 5.67 and 3.70, respectively. The effect of plastic film mulching on Capsicum frutescens showed that the cumulative yield of PM3, PM4 and PM5 was significantly higher than that of CK, with an increase of 4 123, 4 445 kg/hm2 and 5 552 kg/hm2, respectively, and their yield increases were close to or better than that of PE, of which the effect of PM5 on chilli yield enhancement was the most obvious. Therefore, it was recommended to use biodegradable mulch with a thickness of 0.01 mm, mainly composed of PBAT and PHA, for open-air cultivation of Capsicum frutescens.

The results showed that the current planting patterns of Polygonatum sibiricum in Shaanxi Province were mainly divided into two types： Underforest planting and intercropping planting patterns. Planting Polygonatum sibiricum under the forest could effectively utilize the land resources in Shaanxi Province and form a good ecological environment. The intercropping mode of Polygonatum sibiricum created a good rhizosphere environment for the growth of Polygonatum sibiricum, improved the agro-ecological environment, and promoted the regeneration and recycling of resources.
