摘要
试验期间在土壤pH6.3,平均土壤湿度14.5%,平均空气湿度64.9%,平均日照强度19600Lx的条件下,与普通地膜作对照,对3种降解膜A,B,C进行了盖膜栽烟试验,结果降解膜A开裂期为30d,降解膜B开裂期为36～39d,降解膜C开裂期为92～96d.与对照相比,开裂期适宜的降解膜有利于后期的烤烟生长。
With ordinary film as contrast, three kinds of decompose film, A, B and C, were made a trial to mulching tobacco field under the conditions of pH 6.3, 14.5% of soil moisture, 64.9% of air moisture, 19?600 lx of sunlight intensity. The results reveal that the dehiscence time of A is 30 days after mulching, B is 36 to 39 days and C is 92 to 96 days. Compared with the contrast, suitable decompose films are favor of late stadge tobacco growth.
