1.花芽新梢生长期(1)温度。萌芽后至开花,是葡萄新梢初期生育时期。在这一段时间里,一面进行新梢生长,一面进行花器分化。此时温度过高,必将使新梢发生陡长生育,使花器分化质量下降乃至退化,影响结实,所以要实行低温管理。也就是萌芽后的温室温度管理指标,要从催芽末期的高水平 1. Flower bud shoots growing season (1) temperature. After germination to flowering, is the early grapevine shoot growth period. In this period of time, while performing shoot growth, floral differentiation. At this time the temperature is too high, it will make the shoots grow steep long birth, so that the quality of flower differentiation and degradation of degradation, affecting strong, so to implement low-temperature management. That is, after the bud of greenhouse temperature management indicators, from the end of the high level of germination
