不同整形方式及负载量对'北冰红'葡萄的影响研究
Study on the Influence of Different Training Systems and Crop Loading on'Beibinghong'Grape
摘要
Abstract
To study the effects of different training systems and crop loading on photosynthetic rate of leaves,chlorophyll content,plant yield and fruit quality by 'Beibinghong'grape with two training systems,double cordon system and single slanted horizontal system.In the Na-tional Germplasm Grape Resource Nursery of Zuojia Town,Jilin City,five loads were set with the double cordon system+fan-shaped leaf curtain as the control and single slanted horizontal system+"V"-shaped leaf curtain as the treatment.Compared with the double cordon sys-tem,the photosynthetic rate and chlorophyll content of vines in the single slanted horizontal system were higher,and the V6 treatment was higher than the other treatments.The yield of V6～V10 treatment was lower than that of CK,and the yield of V8 treatment was higher than that of other treatments.The fruit reducing sugar content of different treatments was higher than that of CK,and the difference was extremely significant,among which V7 treatment was the highest.The titratable acid content of different treatments was lower than that of the control,and the difference was significant,among which the V8 treatment was the lowest.The ratio of sugar and acid in different treatments was higher than that in the control,and the difference was extremely significant,among which V7 treatment was the highest.The tannin content of different treatments was lower than that of the control,except for V10 treatment,there was no significant difference.The fruit quality of'Beibinghong'grape can be improved by using the slanted horizontal dragon dry shaping method,and the fresh fruit yield of 1 000 kg/667m2 is more suitable when 8 fruit branches are left at the plant spacing of 1 m.关键词
