Abstract:

In order to study the residual status of agricultural film used in greenhouses and analyze the effects of different types of agricultural films on soil nutrients and chilli yield, this study set the no mulching treatment as the control (P1), and six treatments covered with 0.01 mm black PE film (P2), 0.006 mm black PBAT film (P3), 0.008 mm black PBAT film (P4), 0.01 mm black PBAT65%+PPC35% film (P5), and 0.01 mm white PBAT65%+PPC35% film (P6), to analyze chilli yield, residual amount of agricultural film and soil nutrients. The results showed that using different types of agricultural film could increase chilli yield, improve soil moisture conditions, and the residual amount of agricultural film and its impact on soil nutrients differed from different types of agricultural film. Compared to the control, the content of available potassium increased in all film covering treatments; the content of soil available phosphorus increased in P2, P3, and P4 treatments, while soil available phosphorus content decreased in P5 and P6 treatments. The use of different types of agricultural mulching treatments can increase the yield and fresh weight of chilli, and the effect of 0.006 mm black PBAT film was most significant; The 0.01 mm white PBAT65%+PPC35% film had the highest residual amount, while the 0.01 mm black PE film had the highest degradation amount and degradation rate. The results of principal component analysis indicated that the degradation rate of agricultural film, ammonium nitrogen, and available phosphorus were the main factors affecting the yield of chilli. Overall, the use of 0.006 mm black PBAT film in greenhouses is more conducive to increasing chilli yield and soil nutrient content, making it an optional material for vegetable production in greenhouses.
