以11～12a生的“贵长”猕猴桃(Actinidia chinensis‘Guichang’)为试材,观察分析了其新蔓生长与果实生长变化的动态。结果表明:新蔓生长期达147d,其中春蔓生长期达63～70d,二次蔓生长期达70～77d;加粗生长一直长到9月中旬,其中春蔓加粗生长期长达189d;二次蔓加粗生长期达116d。新蔓在整个生长过程中生长量和日生长量都出现2～7次生长高峰期。果实生长期长达133～140d,果实纵横径生长呈多S形生长曲线,在生长期内出现3～5次生长高峰期。新梢生长与果实发育关系密切,表现为前期8周春蔓生长快,以后4周春蔓和二次蔓生长极慢,果实生长极快,再后6周春蔓停止生长,二次蔓生长极快,果实生长较慢,以后二次蔓和果实纵径生长极慢,而果实横径生长较慢,直至都停止生长,在整个生长过程中存在协同。根据猕猴桃新蔓和果实生长发育动态的分析,建议在猕猴桃生产管理时,在上年加强水肥管理的同时选择在5月中旬作为最佳施肥时期,同时要求在果梢生长旺期加强根外追肥,以满足蔓果的养分需求。
Actinidia chinensis ’Guichang’ from 11 to 12a was used as test material to observe the dynamic changes of its new growth and fruit growth. The results showed that the growth stage of new vine reached 147 days, in which the growth stage of spring vine reached 63 ~ 70 days and the secondary growth stage reached 70 ~ 77 days. The bold growth reached the middle of September, Man thick growth of up to 116d. New vine in the growth of the entire growth process and the amount of daily growth occurred 2 to 7 times the peak growth. The fruit growing period was 133-140d, and the growth of the fruit was a S-shaped growth curve in length and breadth. The growth peak appeared in 3 ~ 5 growth stages. The growth of shoots was closely related to the fruit development. The early spring 8 weeks had a rapid growth. After 4 weeks, the spring and secondary growth of the shoots was extremely slow. The fruits grew extremely fast. Then the spring vinelets stopped growing at 6 weeks. Slow, after the second vine and fruit vertical growth very slow, while the fruit diameter growth slower, until all stopped growing, there is synergy throughout the growth process. According to the analysis of the growth and development of Actinidia deliciosa and fruit, it is suggested that in the management of kiwifruit production, we should choose the best fertilization period in mid-May while strengthening the management of water and fertilizer in the same year, , To meet the nutrient needs of cranberries.
