摘要
以云蔗05-51为试验材料,在甘蔗中耕培土前比较4种除草膜对马唐、牛筋草和狗尾草3种常见杂草的防治效果,并调查覆盖4种除草膜对甘蔗出苗量的影响;在甘蔗成熟期,分析覆盖4种除草膜对蔗茎产量、蔗糖分、还原糖分、重力纯度和糖锤度的影响。结果表明,除草膜1号、除草膜3号、除草膜4号除草效果极显著高于普通地膜,除草膜1号、除草膜2号对狗尾草的防治效果达100%,除草膜3号、除草膜4号对牛筋草的防治效果达100%;各除草膜覆盖下甘蔗出苗量、产量、蔗糖分、重力纯度、还原糖分、糖锤度差异均不显著。
This study was conducted on seedlings. The effects of grand covers of four different herbicidal membranes on controlling three common weeds [ Eleusine indica （ L .） Gaertn. ], [ Digitaria sanguinalis （L . ） Scop. ] ,and [ Setaria viridis （L . ） Beauv ] and number of emerged seedlings of sugarcane variety YZ05-51 were investigated before the first field cultivation. Herbicidal membrane No.1 was composed of 85% polyethylene,10% herbicidal granule-A,and 5% herbicidal granule-B. Herbicidal membrane No.2 was made of 90% polyethylene, 5% herbicidal granule-A,and 5% herbicidal granule-B. Herbicidal membrane No.3 consisted of 90% polyethylene and 10% herbicidal granule-A. Herbicidal membrane No.4 contained 90% polyethylene and 10% herbicidal granule-B. At sugarcane maturation stage,data were collected on stalk weight, sucrose content, gravity purity, reducing sugar content, and Brix. The results showed that grand cover of herbicidal membrane No.1, No.3,or No.4 were significantly more effective in controlling the weeds than polyethylene membrane grand cover （CK）. Grand cover of herbicidal membranes No.1 or No.2 controlled the S. viridis weeds at 100% ; whereas grand cover of herbicidal membranes No.3 or No.4 totally eradicated the E.indica weeds. However, no significant difference was observed among various treatments on number of seedlings,cane yield,sucrose content,gravity purity, reducing sugar content,and Brix.
