普洱市甘蔗全膜覆盖综合配套技术试验初报

Preliminary Report on Comprehensive Integrated Techniques with Complete Film Mulch of Sugarcane in Pu'er

为解决干旱问题,采用全膜覆盖与不盖膜、半盖膜综合配套技术在新植、宿根甘蔗上进行对比试验。结果表明,甘蔗全膜覆盖综合配套技术在新植、宿根甘蔗上的出苗、分蘖率和有效茎数等性状较为突出,产量比半盖膜、不盖膜分别增加28.7%、20.9%~63.8%,含糖量比半盖膜、不盖膜分别增加12.9%、28.3%~29.0%;但蔗糖分却低于半盖膜和不盖膜。经济效益显著,可在全市大田生产中推广应用。

In order to solve drought problem, a comparative test of integrated technique with complete film mulch（covering cane seedling and soil）, half film mulch（only covering cane seedling） and no film mulch on new plant and ratoon sugarcane was conducted. The results showed that the emergence of seedling, tillering rate and number of effective stem on new plant and ratoon cane with the comprehensive technology that covered with complete film mulch were prominent, in comparison with that of half film mulch and no film mulch, the yield per unit area significantly increased by 28.7% and 20.9%-63.8%, and the sugar yield increased by 12.9%, 28.3%-29.0%, while the sugar content were lower. Economic benefits were remarkable with the complete film mulch,and it could be popularized and applied in the field production of the whole city.
