摘　　要：为探讨地膜减量替代技术,通过设置3种全生物降解膜、强化膜和普通地膜,研究降解膜的降解过程,以及其对土壤温湿度、残留、人工成本和芋头产量的影响。结果表明,降解膜1裂解最早,降解膜2裂解最慢;降解膜未降解前能起到较好的保温保湿效果,随着降解膜的裂解,保温保湿水平下降;强化膜和降解膜2都较为省工,强化膜用工最少;降解膜2的产量最高,增产62.45%,降解膜1产量最低,减产0.58%。由此说明,降解膜2具有显著的增产作用,可满足作物生长期温湿度的需求,起到省工节本、防草的作用,可替代普通地膜,具有较好的推广价值和应用前景。In order to explore the technique of reducing and substituting plastic film,three kinds of fully biodegradable films,enhanced film and ordinary plastic film were used to study the degradation process of degradable films,as well as their effects on soil temperature and humidity,residue,labor costs and taro yield.The degradation film could play a better role in heat preservation and moisture retention before degradation.With the cracking of the degradation film,the level of heat preservation and moisture retention decreased.Both enhanced film and degradable film 2 were more labor-saving,and the enhanced film had the least labor.The yield of degradation film 2 was the highest,increasing by 62.45%,while the yield of degradation film 1 was the lowest,decreasing by 0.58%.Thus,it was indicated that degradable film 2 had a significant yield-increasing effect,which could meet the temperature and humidity requirements during the crop growth period,save labor and cost,and prevent weeds.It could replace ordinary plastic film,and had good promotion value and application prospects.
