摘要
比较了南京椴种子解除休眠后不同播种方式和催芽程度移栽对苗木成活率的影响,结果表明:当种子"露白"后采用条播直接播种到大田,出苗率仅为10%;而直接播种到50T孔穴盘中,出苗率也仅为16%;将"露白"种子在15℃恒温培养箱中长到5 cm高、子叶完全展开时再移栽到穴盘中,幼苗成活率可达96%。此外,南京椴芽苗移栽后要立即喷施1∶500(m∶m)的"恶霉灵",之后每7天1次,直至茎干木质化为止,这样可以有效防止猝倒病发生。
The effects of sowing methods and accelerating germination levels on the survival rates of T.miqueliana was studied after the deep dormancy of seeds was broken.The results showed that when the ＂germination＂ seeds were directly sowed into the field,the rates of emergence was 10%,and when they directly sowed into the 50-well containers,the rates of emergence was only 16%.However,when the ＂germination＂ seeds were incubated at 15℃ until they grew up to 5 cm tall and the two cotyledon were completely extended and then transplanted into the 50-well containers,the survival rates of the young seedlings of T.miqueliana were reached to 96%.After transplanted,the young seedlings were sprayed the hymexazol at the concentration of 1∶500 immediately,and then once a week until the stem was completely lignified,which could reduce the rates of damping-off disease efficiently.
