| 摘 要： | 利用枣树嫁接技术进行铃铛枣坐地砧嫁接建园，并应用logistic模型定量分析嫁接苗年高生长节律。分析表明铃铛枣嫁接苗的年高生长进程呈现慢一快一慢的“S”形节律，存在着明显的速生期，速生期长达45d，速生期内的苗高生长量约占总生长量的78％。辽西枣区枣农可依此规律抓准生长点，适时安排有效的管理措施，最大限度地提高嫁接苗的生长量。

| Abstract: | The orchards were established by using the grafting techniques of bell jujube and analysis of the annual height growth rhythm of grafted seedlings quantitatively by means of logistic model was conducted. The results showed that bell jujube grafted seedlings had a slow-fast-slow S shape rhythm growing process.There was a clear fast-growing period, which went up to 45d. The seedling height growth during the period of fast-growing accounted for 78% of the total increment. Jujube farmers in western Liaoning cou... |
