近几年,我县从外地引进了许多葡萄新品种,其中大粒鲜食良种巨峰已成为我县的葡萄主栽品种。由于巨峰葡萄落花落果严重,投产后各地的丰产性表现不一,产量不稳,为此,今年5月中旬至6月中旬,我们对7个葡萄园的2～5年生巨峰落花落果情况进行了观察和调查,试图从中摸索规律,探讨其原因和稳果技术。现将本次调查结果报道于后。一、落花落果规律巨峰葡萄的开花时间因立地条件和生长状况不同有所差异,今年我县巨峰的开花始末大多在5月15～26日间,因此发生落花落果时间也有先后,但落果高峰集中在5月26日～28日,即出现在始花后6～12天,盛花后4～8天,花前落蕾不明显。调查结果表明,巨峰葡萄同一果穗、同一新梢、或同一植株,凡花蕾成熟早、开放
In recent years, our county has introduced many new grape varieties from the field. Among them, Kengfeng, a large-grain fresh-eating variety, has become the main grape variety of our county. Due to the grave fall of Kyoho grapes, the fertility of different regions showed mixed performance and instability after the start of production. Therefore, from mid-May to mid-June this year, we carried out the deciduous 2- Observation and investigation, trying to explore the law from which to explore the causes and stability techniques. Now report the results of this investigation later. First, the law of falling flowers Kyoho grape flowering time due to different site conditions and the growth of different conditions, this year, most of my county Kyoho flowering between May 15 to 26, so the time has fallen, but the peak fruit drop focus In May 26th ~ 28th, that is, 6 to 12 days after the first flowering, 4 ~ 8 days after full flowering, before flowering bud is not obvious. The survey results show that the same fruit spike, the same shoot, or the same plant, where buds mature early, open
