摘要
针对传统塑料地膜残膜污染土壤现状,连续引进不同规格和类型的全生物降解地膜在越冬大白菜上进行试验,研究其降解性能及对作物生长和产量的影响.结果表明,试验所采用的几种黑色全生物降解地膜对大白菜生长和产量影响均不显著,在大白菜种植过程中发生不同程度的降解,也不影响后续大型机械翻耕和后作水稻的种植,使用后翻入土壤内的降解膜在 2 a后残留可忽略不计.其中 8 μm 规格的黑色降解膜生产实用性最高,已推广应用 4 a,应用效果良好.
Abstract
In response to the current situation of soil pollution caused by plastic film mulching residue,different specifications and types of biodegradable mulch films were continuously introduced to study its degradation properties and its impact on crop growth and yield of overwintering Chinese cabbage.The results showed that the effects of several black biodegradable mulch films used in the experiment on the growth and yield of Chinese cabbage were not significant.Different degrees of degradation occurred during the planting process of Chinese cabbage,and it did not affect the subsequent large-scale mechanical plowing and subsequent rice planting.The residual degradation film flipped into the soil after two years of use was negligible.Among them,the black degradation film with 8 μm specification has the highest practical production and has been promoted and applied for four years,with good application results.
