通过对杭州园林人工群落中白花杜鹃生长、发育的研究表明,1.杜鹃生长发育可分为4个时期。其中5月中旬至7月初的快速生长期和8月初至10月上中旬的花芽分化期是杜鹃生长、发育的两个关键时期。2.枝条生长适温为20～25℃。3.枝条生长、发育最佳生境的相对光强为50％～60％。4.高的空气湿度、土壤湿度,充沛的降雨量促进杜鹃的生长、发育。5.不同人工群落中杜鹃枝条生长、发育各异,并以马尾松、湿地松和鸡爪槭等组成的群落环境有利于杜鹃的生长和发育。
Through the study on the growth and development of Rhododendron simiarum in artificial garden in Hangzhou, the results showed that: 1. Rhododendron growth and development can be divided into four periods. Among them, the rapid growth period from mid-May to early July and the early-mid-August flower-bud differentiation are the two key periods for the growth and development of Rhododendron. 2. Branch growth temperature is 20 ~ 25 ℃. 3. Branches grow, the best habitat development relative light intensity of 50% to 60%. 4. High air humidity, soil moisture, abundant rainfall to promote rhododendron growth and development. The growth and development of azalea branches in different artificial communities were different, and the community environment of Pinus massoniana, Pinus elliottii and Acer palmatum were favorable to the growth and development of rhododendron.
