Abstract: An experiment was conducted to explore the effects of dryland film mulching cultivation on the variation of soil temperature and yield of Angelica sinensis. Angelica sinensis was planted under film mulching and in open field with single factor randomized block design. Each treatment was repeated with three times. The variation of soil temperature and yield of Angelica sinensis of different observation times, different-layer outdoor temperature (CK), temperature on plastic film (A), temperature of plastic film side (B), and soil temperature between plastic films (C) were measured. The results showed that the temperatures of different detection locations and different layers varied along with the temperature variation. The temperature on plastic film was higher than that of open field. The monthly variation of soil temperature in different layers was A> B>C>CK. The temperature of plastic film, plastic film side, between the plastic film and open field decreased with the increase of soil depth. The highest temperature appeared on plastic film, and the decreasing speed of its layer temperature was the fastest. The yield of Angelica sinensis increased by film mulching cultivation, and the yield was 2975.80 kg/hm2, which was 16.53% higher than that of open field. Film mulching cultivation had a significant effect on soil temperature, soil temperature between the plastic film was suitable for increasing the yield of Angelica sinensis.
