摘    要:PBAT与PPC是化学合成型全生物可降解材料,也是目前地膜可降解材料的研究热点,本研究重点探讨PBAT和PPC材料可降解地膜的实际使用效果。设置PBAT-PPC地膜、PBAT-PPC-BioM地膜、传统PE地膜和露地对照NoFilm处理。通过田间试验,探讨不同地膜处理对地表温度、杂草和豇豆产量的影响,并评估地膜降解性能和最终经济效益。结果表明:PBAT-PPC地膜可有效提高5—7月份地表温度0.9ºC,降低7—8月份地表温度0.2~1.6ºC。PBAT-PPC地膜与PBAT-PPC-BioM地膜均能显著提高了豇豆产量,分别较不覆膜对照处理产量提高37%和22%。PBAT-PPC地膜与PE地膜的杂草产量无显著差异,较露地杂草降低45%。试验期内,可降解地膜降解等级达到4~5,满足后期翻耕回田要求。效益分析表明,尽管可降解地膜成本较高,但增产效果显著,整体收益高于无地膜对照,且无环境风险。综上所述,基于PBAT和PPC的可降解地膜性能优异,在豇豆生产中增效明显,具有较高的推广价值。

Abstract:PBAT and PPC are biodegradable materials based on chemical synthesis, which have become current research hot spot. The aim of this study is to discuss the practical effects of PBAT and PPC mulch film in agricultural production. Four different mulch film treatments were conducted, including PBAT-PPC film, PBAT-PPC-BioM film, PE film and No-film treatment (CK). Effects of different mulch film treatments on surface soil temperature, weed productivity and cowpea yield were studied, and the degradable properties and final economic benefits of mulch film were evaluated. The results showed that compared with CK, the PBAT-PPC film treatment increased surface soil temperature by 0.9℃ from May to July and decreased surface soil temperature by 0.2-1.6℃ from July to August. The PBAT-PPC film and PBAT-PPC-BioM film significantly promoted cowpea yield by 37% and 22%, respectively. There was no significant difference of weed productivity between PBAT-PPC mulch film and PE mulch film, but the mulch film treatments decreased about 45% weed biomass compared with CK. The biodegradation grades of PBAT-PPC and PBAT-PPC-BioM were level 4 and level 5, respectively, which satisfied the requirements of tillage and in situ biodegradation. Although the cost of degradable mulch film was relatively high, the effect on cowpea yield was obvious, and the total income was higher than that of CK. In addition, the degradable mulch film had no environmental risk. Above all, the mulch film based on PBAT and PPC is beneficial to cowpea production and worth promoting.
