摘要
为了摸索全生物降解地膜在果蔗上的应用效果,研究降解地膜代替普通地膜覆盖的可行方法,为此,开展了不同全生物降解地膜在果蔗上进行了覆盖应用对比试验。结果表明:果蔗春植(播)栽培(2月中旬~3月中旬)应用降解膜与普通地膜平均有效茎基本一致,且对果蔗长势和产量无显著差异,可以基本满足春植果蔗栽培的需要,但降解地膜对土壤升温较普通PE地膜性能差;厚度为14μm规格降解地膜的诱导、开裂时间基本上能符合果蔗春植(播)栽培农艺节点需要,培土后,果蔗新生根系均能穿破残存降解膜吸收肥水,待收获翻耕后观察,田间无残留,可实现省工节本、绿色生态。
In order to explore the application of biodegradable mulch on chewing cane,and looking for a feasible method to replace ordinary mulch with biodegradable mulch,a comparative test of covering application of different fully biodegradable mulch on chewing cane was carried out.The results showed that,on the chewing cane cultivated in spring(from mid-February to mid-March),the average effective stem after using biodegradable mulch and ordinary mulch was almost the same,the growth and yield of chewing cane also had no significant differences.The application of biodegradable mulch could basically meet the needs of chewing cane cultivated in spring,however,the performance of biodegradable mulch on soil heating was worse than that of ordinary mulch;the induction and cracking time of biodegradable mulch with a thickness of 14μm could basically meet the needs of the agronomic nodes of spring planting chewing cane;after the chewing cane covered with soil,new roots could wear out new residual degradation of membrane absorption and water,after harvesting and ploughing,no mulch residue would be found in the field,saved labor and cost,green ecology.
