江苏省沿海地区避雨棚栽培对葡萄品质的影响

摘要

以维多利亚、白罗莎里奥、魏可为研究对象,研究避雨栽培对葡萄品质的影响。以露地栽培为对照,测定葡萄的粒重、横纵径、可溶性固形物含量、含糖量、维生素含量等指标。结果表明：避雨栽培条件下葡萄的粒重、横纵径显著优于露地栽培,避雨栽培条件下3个葡萄品种的含糖量略低于露地栽培;避雨栽培条件下葡萄的可溶性固形物含量和维生素含量显著高于露地栽培。避雨棚栽培可提高葡萄的品质。%The effects of rain shelter greenhouse cultivation on grape quality were researched with Rosario Bianco,Wink and Victoria.The indexes of grape grain weight,vertical and horizontal diameter,total soluble solids content,soluble sugar content and vitamin content were tested in two different conditions of rain cultivation and open cultivation.The results showed that the indexes of grain weight,vertical and horizontal diameter,total soluble solids content and vitamin content in rain shelter greenhouse cultivation were higher than those indexes in open cultivation.The soluble sugar content in rain shelter greenhouse cultivation was slightly lower than the index in open cultivation.The rain cultivation shelter greenhouse could improve the quality of grape.
