| 目的 为促进植株生长，减少地膜残留对下茬作物产量的影响，选用聚对苯二甲酸-己二酸-丁二醇酯(PBAT)与聚-3-羟基丁酸酯-co-4-羟基丁酸酯(P34HB)制备地膜，探究其对番茄生长的影响。方法 将PBAT和P34HB以9∶1、8∶2、7∶3质量比共混，通过水冷造粒、吹塑生产3款具有不同力学和阻隔性能的地膜，并应用于番茄作物生产。结果 随着P34HB含量的增加，复合膜的拉伸强度和透湿性增强，9∶1地膜对番茄具有一定增益作用，且单垄残留量约为16片。结论 PBAT/P34HB(9∶1)地膜的性能满足番茄生产，具有增益作用，并减少了地膜残留造成的污染。 |
| 英文摘要: |
| The work aims to prepare mulch films with poly (terephthalate-adipate-butanediol) (PBAT) and poly (3-hydroxybutyrate)-co-4-hydroxybutyrate (P34HB) and study their effect on tomato growth, so as to promote plant growth and reduce crop yield caused by film residue. The technical route was to blend PBAT and P34HB at 9∶1, 8∶2 and 7∶3 mass ratios, and produce three mulch films with different mechanical and barrier properties through water-cooled granulation and blow molding, and then apply them to tomato production. The results showed that with the increase of P34HB content, the tensile strength and moisture permeability of the composite film were enhanced. The 9∶1 film had a certain effect on tomato production, and the residual amount of a single row was about 16 pieces. It is concluded that the performance of the PBAT/P34HB (9∶1) film can satisfy the tomato production. It has the effect of increasing production, and reduces the pollution caused by the film residue. |
