为了研究甘蔗地膜双沟覆盖对土壤温度、水分、甘蔗工农艺性状的影响,以常规地膜半覆盖为对照进行了比较试验,结果表明:甘蔗地膜双沟覆盖栽培与常规半覆盖栽培比较,土壤温度提高1.6℃、土壤含水量提高3.6个百分点、甘蔗出苗率提高11.2个百分点,分蘖率提高21.5个百分点、蔗茎产量增加1180kg/667m2、蔗糖分提高0.41个百分点;甘蔗地膜双沟覆盖除了每667m2增加2.83kg地膜成本外,其它生产成本与常规半覆盖栽培相同,具有很好的经济效益。
In order to study the effects of plastic double-furrow mulching on soil temperature, water and agricultural and agricultural properties of sugar cane, conventional plastic film was compared with that of semi-plastic mulching. The results showed that compared with conventional semi-mulched plastic mulching, the soil temperature Increased soil water content by 3.6%, increased the emergence rate of sugarcane by 11.2%, tillering rate increased by 21.5%, cane yield increased by 1180kg / 667m2, and sucrose content increased by 0.41%. Except for every 667m2 Increase 2.83kg plastic film costs, other production costs and conventional semi-covered cultivation of the same, with good economic benefits.
