摘要
通过田间试验,研究了甘蔗全田宽膜覆盖、窄膜覆盖及不盖膜3种不同处理对耕层土壤水分,以及甘蔗株高、产量及效益的影响。结果表明,与窄膜覆盖及不盖膜处理相比,甘蔗全田宽膜覆盖有利于在旱季维持较高的耕层土壤含水量,使甘蔗株高在9~10月份生长速度达1.95 cm/天,显著高于不盖膜和窄膜处理的1.54和1.57 cm/天,并最终导致收获时全田盖膜处理甘蔗株高达到365.7 cm,显著高于窄膜覆盖和不盖膜处理。蔗产量及效益分析结果表明,全田宽膜覆盖比不盖膜处理蔗产量提高了29.4t/hm^2,增幅达29.8%,增收11022元/hm^2,增幅达52.8%。
A field experiment was conducted to evaluate the arable layer soil water content, sugarcane height, cane yield and benefits among the treatments of whole plastic film mulching with wide film, half plastic film mulching with narrow film and no plastic film mulching. The results showed that the treatment of whole plastic film mulching had higher arable layer soil water content during the dry season, and also had higher sugarcane growth rate. In September to October, the height growth rate of whole plastic film mulching was 1.95 cm/d, which was significant higher than 1.54 cm/d of no plastic film mulching and 1.57 cm/d of half plastic film mulching, finally resulting in the highest cane height in harvesting. The cane yield and benefits increased by 29.8% and 52.8% respectively, compared with the treatment of no plastic film mulching.
