Abstract：
In recent years, polybutylene adipate-co-terephthalate (PBAT) mulch film has become one of the most commonly used biodegradable mulch films in agriculture in an attempt to combat plastic film pollution. However, its degradation characteristics and impact on the soil environment and crop growth are affected by many factors such as its composition, soil and crop types, local climate characteristics, etc. In this study, PBAT mulch film and ordinary polyethylene (PE) film were used as test materials, with non-mulching treatment (CK) as a control, to study the applicability of PBAT film in Moyu County, Southern Xinjiang region, using tomato growth as an example. The results showed that PBAT film started its induction period after 60 days, and 60.98% of the PBAT film was degraded within 100 days. Generally, the soil temperature and humidity preservation functions of this film were comparable to that of PE film in the seedling and flowering-fruiting stages of tomato growth. In the mature stage, the soil humidity under PBAT film was significantly lower than that of PE film due to its substantial degradation rate. However, this did not have any significant negative effects on tomato growth, yield, and quality. The tomato yield of 667 m2 with BPAT was insignificantly lower than that of PE film by 3.14%, and both were significantly higher than that of the CK treatment by 63.38% and 68.68%, respectively, indicating that it is feasible to use PBAT film to cultivate crops such as tomato in the arid region of Southern Xinjiang, China.
摘要：
近年来,聚己二酸丁二醇酯-对苯二甲酸酯共聚物（PBAT）地膜已成为农业中最常用的可生物降解地膜之一，以对抗塑料膜污染。然而,其降解特性及其对土壤环境和作物生长的影响受多种因素的影响,土壤和作物类型，当地气候特征,等。在这项研究中,以PBAT地膜和普通聚乙烯(PE)膜为试验材料,以非覆盖处理（CK）为对照，为了研究PBAT薄膜在墨玉县的适用性，南疆地区,以番茄生长为例。结果表明，PBAT膜在60天后开始诱导期，60.98%的PBAT膜在100天内降解。一般来说,在番茄生长的幼苗和开花结实阶段，该膜的土壤温度和湿度保存功能与PE膜相当。在成熟阶段,PBAT膜下的土壤湿度明显低于PE膜，因为其降解率很高。然而,这对番茄生长没有任何显著的负面影响，产量，和质量。用BPAT处理667m2的番茄产量不显著低于PE膜3.14%，均显著高于CK治疗的63.38%和68.68%,分别,表明在南疆干旱地区使用PBAT膜种植番茄等作物是可行的，中国。
