摘要
以温克等10个葡萄品种为试材,通过结果习性观察,从不同促萌时间等方面研究其一年两熟栽培技术。结果表明:早红提、维多利亚、时代1号、夏黑、小贝和温克等6个品种易产二造果;二造促萌剪口粗度应大于0.8cm;结果枝冬芽和一次副梢夏芽二造成花率高,是生产二造果的主要芽类;两代同堂适宜的促萌时间为5月下旬至7月上旬,两代不同堂适宜的促萌时间为7月下旬至8月上旬;促萌至二造果成熟,早熟和中熟品种需97d、晚熟品种需144d,可作为推断促萌时间调节熟期的参考。
To take ten varieties such as Wenke as experimental materials, observing their fruit-setting characters, a research of annual two-maturity cultivation technology in aspects of different germination-promoting time etc. the results show Six varieties such as Zaohongti etc. are easier to produce second harvesting fruits. The snip diameter of germination-promoting should be bigger than 0.8 cm. the winter bud of fruiting branches and summer bud of subsidiary branch will have higher flower-setting rate in second harvest, which are the main buds to produce the second fruits. The suitable germination-promoting time for two generations at same time is from late May to earlier July and the suitable germination-promoting time for two generations not at same time is from late July to earlier August. From germination-promoting to second fruit maturity, it takes about 97 d for early maturity and middle maturity varieties, 144 d for late maturity varieties, which can be the references to forecast germination-promoting time for adjusting maturity period.
