摘  要:
对香樟种子播种一年生苗木的苗高、地径进行了试验分析,结果显示:香樟苗高生长期可划分为4个阶段,即出苗期为3月5日至4月30日,生长初期为5月1日至6月26日,生长盛期为6月27日至9月9日,生长后期为9月10至11月15日;地径也可划分为4个阶段,出苗期为3月5日至4月30日,生长初期为5月1日至6月4日,生长盛期为6月5日至10月6日,生长后期为10月7日至11月15日;所拟合的苗高生长曲线与实际生长曲线吻合程度高,可作为采用育苗技术措施的依据。同时,苗高与地径呈线性相关,一年生的苗木生长率平均苗高72.5cm,苗径0.64cm。

摘  要:
This paper analyzed annual seedling height and ground diameter of the camphor seed.The results showed that high camphor seedling growth period can be divided into four stages:namely the seedling stage is from 5~(th) March to 30~(th) April;growth in the early stage is from 1~(st) May to 26~(th) June;the growth stage is from 27~(th) June to 9~(th) September;the later growth stage is from 10~(th) September to 15 th November.Ground diameter can be divided into four stages:the seedling stage is from 5~(th) March to 30~(th) April;growth in the early is from 1~(st) May 1 to 4~(th) June;the growth stage is from 5~(th) June to 6~(th) October;the later growth stage is from 15 th November to 7~(th) October.The high growth curve of the proposed seedling is highly consistent with the actual growth curve,which can be used as the basis for the adoption of seedling technology.At the same time,the height of the seedlings is linearly dependent.The annual growth rate of seedlings is 72.5cm,and the diameter of the seedling is 0.64 cm.
