地膜覆盖对鲜食葡萄果实及新梢生长发育的影响

选用紫色、白色、蓝色薄膜及蓝色厚膜4种地膜对两葡萄品种里扎马特、凯然诺尔进行覆盖栽培。试验结果表明：覆膜与不覆膜（对照）相比，葡萄覆膜栽培后可提高供试品种座果率50%以上，并可增加供试品种新梢生长量30%；里扎马特品种果粒重可增大40%以上、凯然诺尔品种果粒平均重略有减小；与对照相比，两品种果实中可溶性固形物含量有所下降。经方差分析，处理之间无明显差异。从果实生长发育和新梢生长发育状况来看，以蓝色薄膜的覆盖综合效果为最佳。

Effect of Mulching Film to Fruits and Shoot Growth in Grape

This paper selects four mulching film including of violet,white,blue thin film and blue thick film to compare their effect of cover cultivate.Result indicates that cover cultivate can improve the rate of setting fruit by 50 percent,the growth of shoot by 30 percent,the weighty of fruit grain of variety PNaMaT by 40 percent;Content of soluble solid decreases.Analysis of variance indicates that has not manifest imparity in treatment comparisons,and blue thin film shows best compositive effectiveness.
