中文摘要：
研究糖料蔗膜下滴灌的生长效应，为探索新型高效的节水灌溉模式提供理论支撑。试验设置盖膜＋滴灌（A）、不盖膜＋滴灌（B）、盖膜＋不灌（C）、不盖膜＋不灌（CK）4种处理水平，研究各处理对糖料蔗农艺性状、光合特性、产量和糖分的影响。结果发现：A处理在出苗率、株高、伸长速度、叶绿素、净光合速率、产量等方面表现最好，B处理的有效茎数最多，C处理则在分蘖率、单茎重、纤维分等方面表现最好。运用模糊数学中的隶属函数方法进行综合评价，结果显示，膜下滴灌对糖料蔗的生长效应最好，滴灌次之，对照最差。
英文摘要：
The growth effect of sugarcane under film drip irrigations is studied to provide a theoretical support for exploring new effi‐cient water-saving irrigation modes .Four kinds of treatments have been established ：covered with films and drip irrigation（A） ,no films covered and drip irrigation（B） ,covered with films and no irrigation （C） ,no films covered and no irrigation （CK） .Research is done on the effects of different treatments on agronomic characters ,photosynthetic characteristics ,yield and sugar of sugarcane .The results show that A performs best in the aspects of germination rate ,plant height ,elongation rate ,chlorophyll ,net photosynthetic rate ,yield ,etc .The effective stems of B are the most .C performs best in the aspects of tillering rate ,single stem weight ,fiber points ,etc .The membership function of fuzzy mathematics is used to make a comprehensive evaluation ,and the results show that the sugarcane growth effect of drip irrigation under films is the best ,that of drip irrigation is better ,the CK is the worst .
