Effects Of Different Organic Fertilizers On Growth And Quality Of Wine Grape

This study is based on Gernischt of8years as the test material, using five kinds of organic fertilization and one conventional fertilization to study the rules of different organic fertilizer on Gernischt shoot length, leaf, fruit vertical and horizontal diameter and diameter, weight, photosynthetic characteristics, sugar content, sucrose metabolism related enzymes, titratable acid, tannin, pigment, etc. And to analyze the influence of the fruit quality index in different organic fertilizer on Gernischt shape growth, photosynthetic physiology, sugar accumulation.The results shows that:1. Under the different organic fertilizers treatment.Compared to chemical fertilizers, bio-organic fertilizer, humic acid organic fertilizer and organic fertilizer nutrition can significantly promote the growth of new grape slightly; compared with the control, the application of the grape grapes organic fertilizer and bio-organic fertilizer blade vertical and horizontal diameter and leaf weight increased slightly, but the difference was not significant; The grape fruit and fruit weight can be increased by bio-organic fertilizer and humic acid bio-organic fertilizer, the differences were not significant.2. In fruit enlargement and turning stage. The treatment of organic fertilizer and bio-organic fertilize can increased SPAD of leaf. After flowering60d, Pn was the highest on bio-organic fertilizer treatment. After flowering30d, lowest Pn value on conventional fertilization. stomatal conductance no significant difference among treatments; transpiration rate after flowering45d, humic acid bio-organic fertilizer treatment was the highest, and30d conventional fertilization treatment was the lowest.3. Under the different organic fertilizers treatment.All treatment had no significant effect on the content of sugar in leaf,but the treatment increased the content of sugar in wine grape,and which application of bio-organic fertilizer than control total sugar content to improve10.46%; application of organic manure can reduce grape fruit titratable acid, humic acid organic fertilizer effect is most obvious, the acid content is reduced by about32.90%compared with the control; humic acid organic fertilizer reduces the grape fruit tannin content, other processing unit no significant difference between the tannins and total phenols with the control.
