[目的]为了研究聚丁二酸丁二醇酯(PBS)基共聚物的降解性能及其对冬小麦生长的影响。[方法]将冬小麦分别播种在混有等量PBS,PBS-co-HS,PBS-co-BA的聚合物碎片的土壤中,研究聚合物在土壤中的降解,及其持续降解过程中的降解中间体、降解产物对冬小麦种子发芽及生长的影响。[结果]结果表明,在相同条件下的陕西塿土中,共聚物比PBS显示出更好的生物降解性能;聚合物的加入对冬小麦的发芽率、株高不仅没有影响,反而有利于植株生物量的提高。[结论]因此,可生物降解材料PBS、PBS-co-HS和PBS-co-BA的降解及其降解产物对目前土壤环境中植物的生长没有影响。
[Objective] The study aimed to study the degradation of polybutylene succinate (PBS) based copolymer and its effect on the growth of winter wheat. [Method] The winter wheat was sown in the soil mixed with PBS, PBS-co-HS and PBS-co-BA polymer fragments respectively to study the degradation of the polymer in the soil and its degradation during the continuous degradation Effect of Intermediates and Degradation Products on the Germination and Growth of Winter Wheat Seeds. [Result] The results showed that the copolymer showed better biodegradability than PBS in the same soil conditions. The addition of polymer not only had no effect on the germination rate and plant height of winter wheat, but was beneficial to plant biology The amount of improvement. [Conclusion] Therefore, the degradation of biodegradable materials PBS, PBS-co-HS and PBS-co-BA and their degradation products had no effect on the current plant growth in soil environment.
