摘要：

为了研究温室大棚内不同类型农膜使用的残留状况，并分析使用不同类型的农膜对土壤养分和辣椒产量的影响，本研究设不覆膜处理为对照(P1)，覆0.01 mm黑色PE膜(P2)、0.006 mm黑色PBAT膜(P3)、0.008 mm黑色PBAT膜(P4)、0.01 mm黑色PBAT65%+PPC35%膜(P5)和0.01 mm白色PBAT65%+PPC35%膜(P6)等6个处理分析辣椒产量、农膜残留量和土壤养分。结果表明：使用不同类型的农膜都能够增加辣椒产量，改善土壤水分条件，农膜的残留量及其对土壤养分的影响因农膜类型的不同存在差异。与不覆膜处理相比，所有覆膜处理的土壤速效钾含量均增加；P2、P3和P4处理的土壤速效磷增加，P5和P6处理的速效磷含量降低；使用不同类型的农覆处理均能增加辣椒产量和植株鲜重，使用0.006 mm黑色PBAT膜的效果最显著；0.01 mm白色PBAT65%+PPC35%膜的残留量最大，0.01 mm黑色PE膜的降解量最多，降解率也最高。主成分分析结果表明，农膜降解率、铵态氮和速效磷是影响辣椒产量最主要的因素。综合而言，温室大棚内使用0.006 mm黑色PBAT膜更有利于增加辣椒产量和土壤养分含量，是温室大棚蔬菜生产的可选材料。

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.
