不同地膜覆盖对甘薯农艺性状及产量的影响
Effects of Different Plastic Film Mulching on Agronomic Traits and Yield of Sweet Potato
摘要
Abstract
To investigate the influence of different plastic film mulching on sweet potato growth,three cultivars,'Yanshu 25','Hami',and'Long 9',were used as test subjects.The effects of black film mulching,white film mulching,and black and white film mulching on the main agronomic traits and yield of sweet potatoes were studied.The results demonstrated that plastic film mulching improved all measured agronomic traits and yield to varying degrees,with the most significant enhancements observed under black-white composite film and black film mulching.Compared to the non-mulching control(P<0.05),black-white film mulching treatment increased the yield of'Yanshu 25'and'Hami'by approximately 20%.Across the three cultivars,the yield improvement followed this order:black-white film>black film>white film>no mulching.Correlation analysis between agronomic traits,quality,and yield revealed that branch number per plant,marketable rate,and dry matter content showed significant correlations with aboveground fresh weight,while yield was significantly correlated with underground fresh weight.The response to different mulching treatments varied among sweet potato cultivars,which may be attributed to intrinsic crop characteristics and their adaptability to environmental conditions.This study shows that black and white plastic film mulching significantly improves the yield and quality of sweet potato,and has important application prospects.关键词
