新植甘蔗不同盖膜方式的效应研究

Effects of Different Film Mulching Patterns on Newly Planted Sugarcane

选用粤糖60号作为试验材料,开展新植甘蔗不同盖膜方式的效应研究,研究在不同地膜和不同盖膜方式下甘蔗农艺性状、工艺品质、产量性状和生理指标等方面的表现。结果表明:在不同的盖膜方式下,覆盖光降解除草地膜平均产量高于覆盖普通透明地膜,双行盖膜方式平均产量高于单行覆盖普通透明地膜;覆盖普通透明地膜平均蔗糖分要高于覆盖除草光讲解地膜,双行盖膜方式蔗糖分高于单行盖膜;不同地膜的增温效果不同,其中覆盖普通透明地膜的增温效果最好,覆盖光降解除草地膜普通黑色地膜增温效果最差;在不同的盖膜方式下,覆盖普通透明地膜的甘蔗萌芽率最高,单行盖膜平均萌芽率高于双行盖膜萌芽率;在覆盖黑色地膜下很少生长有杂草,其他地膜都生长有少量或大量杂草。综合各项表现评价,认为使用双行覆盖光降解除草地膜为新植蔗最佳盖膜方式。

Selecting sugarcane variety Yuetang No.60 as test material to study the effects of different film mulching patterns on newly planted sugarcane,analyze such aspects as agrinomic traits,process quality,yield characters and physiological indexs of sugarcane in different mulching patterns with different plastic films.Results showed that the average yield of sugarcane mulched with weeding photodegradable plastic film was higher than that with transparent plastic film,and it in double-row mulching pattern was higher than that in single-row mulching pattern; the average sucrose content of sugarcane mulched with transparent plastic film was higher than that with weeding photodegradable plastic film,and it in double-row mulching pattern was higher than that in single-row mulching pattern; the warming effect of transparent plastic film was better than that of weeding photodegradable plastic film; sugarcane mulched with transparent plastic film had the highest germination rate,and the germination rate in single-row mulching pattern was higher than that in double-row mulching pattern; few weeds grew under black film mulching,and a few or a lot of weeds grew under other film mulching.By comprehensive evaluation of various performance of sugarcane indicated that double-row mulching with weeding photodegradable plastic film was the best mulching pattern for the newly planted sugarcane.
