Effects of Whole Plastic Film Mulching on Arable Layer Soil Water Content and Sugarcane Growth
摘要
Abstract
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.关键词
