影响葡萄产量、品质的冠幕指标分析

The Analysing of vine canopy parameters affected on berry yield and quality

对2 个酿酒品种,5 种整形方式的16 个冠幕指标分析,认为影响产量的主要指标是每株果穗数、穗重和每穗果粒数;影响含糖量的主要指标是叶果比和到达叶片的平均相对光强(即叶幕叶片平均受光状况);

By analysing two wine varietirs′ 16 canopy parameters of five different training systems,the main influence parameters on yield are cluster numder per vine、cluster weight and berry numder per cluster,on sugar content are the leaf areas/berry weight per vine and average relative light intensity of reception,on total acid is the leaf areas/berry weight per vine
