摘要：

为给新川中岛桃果实适期采收提供理论依据,并为制定科学的栽培技术和管理措施提供参考,考察了新川中岛桃新梢和果实生长发育动态及其相关性。结果表明,新梢3月下旬开始生长,7月下旬停上伸长生长,增粗生长仍在继续,9月上旬停止生长,生长期长达184 d,新川中岛桃新梢生长量和新梢叶片增加量均出现4次生长高峰,且后两次生长高峰出现时间一致,二者呈正相关;果实纵径、横径和侧径出现3次生长高峰,除第2次生长高峰外,新川中岛桃果实纵径、横径、侧径和新梢生长高峰交替出现。应加强水肥管理,以果实膨大期前施肥为宜,并根据养分需求及时追肥;采收期以8月上中旬为宜。

摘要：

The growing development trends and correlation of new shoots and fruits of Xinchuanzhongdao peach were analyzed to provide theoretical basis for its optimum picking period and reference for formulating the scientific cultivation technique and management measures.The results show that the new shoots begin to grow in the last ten-day period of March,stop elongation growth in the first ten-day period of July and stop growth in the first ten-day period of September and its growth period is up to 184 d.There are four growth peaks in new shoot increment and leaf increment respectively.The occurrence time of the last two growth peaks of new shoot increment and leaf increment make no difference and there is a positive correlation between new shoot increment and leaf increment.There are 3 growth peaks in fruit vertical diameter,transverse diameter and side diameter and the growth peak of fruit vertical diameter,transverse diameter,side diameter and new shoots alternately occurs except the second growth peak.The optimum fertilizing time is before the fruit expansion stage and the optimum picking period is in the first and middle ten-day period of August.
