摘要
对大沙河自然保护区道真润楠(Machilus dauzhenensis)一年生野外直播苗苗期生长节律进行了研究,研究分析表明:苗高和地径生长呈平缓"S"型曲线生长;苗木生长节律分别经历了慢生期、速生期和渐进停滞期3个时期,苗高速生期从7月上旬至8月上旬止,地径速生期从6月上旬至10月上旬止;苗高、地径年生长量分别为10.9cm、2.0mm。分析道真润楠苗木的生长节律,为不同生长时期采用相应的管理措施提供了科学依据。
The research of Machilus dauzhenensis annual wild seeding period growth rhythm in Dashahe nature reserve showed that the seedling height and ground diameter growth was gentle ＂S＂ type curve; Seedling growth rhythm, respectively, has experienced a slowlife period, fast growth period and progressive plateau three times, seeding high-speed stage from early July to early August, diameter fast-growing period from early June to early October; Annual growth of seedling height, ground diameter is 10.9 cm and 2.0 mm respectively.The studying could provide scientific basis for the corresponding management measures for the different growth periods.
