不同材质生物降解地膜的性能及其对番茄生长的影响

The Performance of Biodegradable Mulching Film of Different Materials and Its Effect on the Growth of Tomato

为筛选适宜应用在塑料大棚番茄种植中的生物降解地膜产品,对比了不同聚己二酸/对苯二甲酸丁二酯(PBAT)材质、PBAT+聚乳酸(PLA)混合材质的全生物降解地膜产品的性能以及其对番茄长势、产量的影响。结果表明:PBAT材质降解膜在抑制水分蒸发、降解性能、提高番茄产量及效益方面,均比PBAT+PLA材质降解膜的效果好,故在塑料大棚番茄生产中可以选用PBAT材质的生物降解膜。

In order to screen biodegradable film products suitable for tomato cultivation in plastic greenhouse,the performance of the products with different poly(butyleneadipate-co-terephthalate)materials and poly(butyleneadipate-co-terephthalate)+polylactide materials,and the growth and yield of tomato were compared.The results showed that the degradation fi lm of butyleneadipate-co-terephthalate material was better than that of butyleneadipate-co-terephthalate+polylactide material in inhibiting water evaporation,degrading property and increasing yield and benefi t of tomato,therefore,the biodegradable fi lm made of butyleneadipate-co-terephthalate material could be used in the production of tomato in plastic greenhouse.
