2000～2001年进行山葡萄生产主栽品种紧穗、中等、散穗的3种穗形中穗梗、“小青粒”占穗重比例调查和果实发酵出汁率试验。结果表明:左山一、左山二、双优、双红和双丰的粗放管理和“超量负载树”大都为散形果穗,其穗梗占穗重高达8.8%～22.4%,比紧穗形增加1.8%～15.5%,“小青粒”占穗重4.4%～7.7%,比紧穗形增加1.2%～7.3%,果实发酵出汁率仅为38.9%～53.0%,比紧穗形降低(少出果汁)8.0%～19.2%,发酵每吨果汁增加果实价款226.5～739.5元。酒厂在收购山葡萄果实,“小青粒”和穗梗占穗重5%和12%以上,每公斤降价0.3～0.4元,甚至拒收。为此,提出调控果穗松散、小青粒多的生产管理技术措施。指导果农生产,增加果农生产效益。
From 2000 to 2001, three kinds of panicles, middle ear and middle ear of main grape varieties of mountain grape, panicle weight proportion survey and fruit juice fermentation rate test of “small green grain” were conducted. The results showed that the extensive management of Zuoshan 1, Zusanli 2, Shuangyou, Shuanghong and Shuangfeng and the “super-load tree” were mostly spikelets with spikes of 8.8% -22.4% Spike shape increased by 1.8% -15.5%, “Small green grain” accounted for 4.4% -7.7% of panicle weight, increased by 1.2% -7.3% than tight spike shape, and the rate of fruit juice fermentation was only 38.9% -53.0% Reduce (less juice) 8.0% ~ 19.2%, increase the fruit per ton of fruit juice price 226.5 ~ 739.5 yuan. Grape wineries in the acquisition of the fruit, “small greens” and spikes account for more than 5% of the spike and 12%, 0.3 ~ 0.4 yuan per kilogram price, or even rejected. To this end, put forward the regulation of loose ears, small green more production management techniques. Guidance of agricultural production, increase fruit production efficiency.
