摘要:

【目的】评价不同类型地膜对棉花长势的影响及自身降解和回收特性的分析。【方法】以聚乙烯地膜(CK)为对照,设置全回收高强度地膜(G)和4种可降解地膜(J1、J2、J3和J4)处理,对比分析地膜类型对棉花长势和产量的影响及地膜回收效果和田间降解情况,筛选出综合性能优异的棉田绿色生产地膜。【结果】CK处理蕾期和花期株高茎粗分别是62.08、7.36和103.75、10.36 cm。降解地膜处理株高较CK显著降低4.66%~13.21%,G处理株高和茎粗较CK无显著差异;CK处理蕾期、花期和铃期地上部生物量分别是17.77、43.36和744.97 g/株。G处理在各生育时期较CK显著提高7.45%~19.90%,且均显著高于降解地膜。CK处理单株成铃数、单铃重和籽棉产量分别为5.37个/株、5.18 g/个和5 642.14 kg/hm2。G处理单铃重较CK显著降低0.23 g/个,但单株成铃数显著提高0.94个/株,产量显著提高620.91 kg/hm2,增幅11.00%。降解地膜处理单株成铃数、单铃重和产量处理间差异均不显著,但均较CK分别显著降低0.22~0.47个/株、0.15~0.30 g/个和8.75%~15.22%。G和CK处理回收率为82.81%和92.16%,但G处理较CK显著提高9.35%。J2处理降解率较高为89.49%,较CK残留率降低6.67%。【结论】降解地膜处理较聚乙烯地膜产量更低。全回收高强度地膜增产620.91 kg/hm2,增幅11.00%,回收率提高9.35%,覆膜应用潜力较好。

Abstract:

【Objective】 Scientific evaluation of the influence of different types of plastic film on cotton growth and its own degradation and recycling characteristics.【Methods】 In this study, the polyethylene mulch (CK) was used as the control, and the recyclable high-strength mulch (G) and four degradable mulches (J1, J2, J3 and J4) were set and their effects on cotton growth and yield, recycling effects and field degradation were compared and analyzed in order to screen out the green production mulch with excellent comprehensive performance.【Results】 The height and stem diameter of CK treatment at bud stage and flowering stage were 62.08 cm, 7.36 cm and 103.75 cm, 10.36 cm, respectively.The plant height of degraded mulch film treatment was 4.66%-13.21% lower than that of CK, and there was no significant difference in plant height and stem diameter between G treatment and CK.In terms of yield performance, the aboveground biomass of CK treatment at bud stage, flowering stage and boll stage were 17.77, 43.36 and 744.97 g/plant, respectively.G treatment was 7.45%-19.90% higher than CK at all growth stages, and was significantly higher than degraded film.Single boll weight and seed cotton yield of CK treatment were 5.37, 5.18 g and 5,642.14 kg / hm2, respectively.Compared with CK, the boll weight of G treatment was significantly reduced by 0.23 g/plant, but the number of bolls per plant was significantly increased by 0.94 per plant, and the yield was significantly increased by 620.91 kg/hm2, an increase of 11.00%.There were no significant differences in boll number per plant, boll weight per plant and yield between the treatment of degraded mulch film and CK, but they were significantly reduced by 0.22-0.47, 0.15-0.30 g and 8.75%-15.22%, respectively.The recovery rates of G and CK were 82.81% and 92.16%, but G treatment was 9.35% higher than CK.The degradation rate of J2 treatment was 89.49%, which was 6.67% lower than that of CK.【Conclusion】 Degradation film treatment cost is lower than that of polyethylene film yield, but it needs further improvement.The total recycle of high-strength mulch film can increase the cotton yield by 620.91 kg/hm2, increased by 11.00%, and the recovery rate increased by 9.35%, which has good application potential, and can be used as a new type of green, safe and environmentally friendly mulch film in cotton field for large-scale extension.
