不同旧膜再利用方式对向日葵产量及水分利用效率的影响
Effect of Re-used Plastic Film Mulching under Different Planting Patterns on Sunflower's Yield and Water Use Efficiency in Hetao Area
摘要
Abstract
Aiming at finding best planting patterns mulching with re-used plastic film, the study investigated the effects of re-used plastic film mulching under different planting patterns( mulching on lines( JS)and mulching under lines( JJ) )on sunflower's yield and water use efficiency by compared with bare field in Hetao area, China. The results showed that,both planting patterns with re-used film mulching could increased soil water at different degree. Compared with bare field, soil moisture of re-used film was higher significantly in 0 -40 cm, and no significant in 40 - 100 cm. Meanwhile, the grain yield and water use efficiency ( WUE ) of re-used film were higher significantly than that of bare field in 0 - 40 cm, especially the grain yield of JJ were higher significantly than that of bare field 12.92% in 2010 and 17.82% in 2011 , than that of JS 1.34% in 2010 and 0. 88% in 2011 ,but no significant. So it was worth to apply re-used film to agriculture production for improving the soil moisture,enhancing water use efficiency and increasing the yield of sunflower. At the same time,especially,we suggest that the application of re-used film mulching on the lines as a suitable soil management practice increase soil water and WUE in Hetao area or other areas with similar conditions.关键词
