摘要
对喜树播种苗采用6种移植密度(株行距分别为10 cm×10 cm、10 cm×15 cm、15 cm×15 cm、15 cm×20 cm、20 cm×20 cm、20 cm×25 cm)进行幼苗生长对比试验,结果表明:喜树播种苗移植密度以株行距15 cm×15 cm最适宜,1年生幼苗平均地径达1.14 cm,平均苗高达109.5 cm,主根平均长度达30.1 cm,>5 cmⅠ级侧根平均条数达28.7条,合格苗率达33.4%,合格苗产量8.91万株·hm-2。
The use of six kinds acuminata seedling transplanting density ( spacing respectively 10 cm ×10 cm, 10 cm ×15 cm, 15 cm ×15 cm, 15 cm ×20 cm, 20 cm ×20 cm, 20 cm ×25 cm) were seedling growth comparative test results showed that:acuminata seedling transplanting density optimum spacing 15 cm ×15 cm, 1 year old seedlings average diameter up 1.14 cm, average seedlings up to 109.5 cm, the average length of 30.1 cm taproot,>5 cmⅠ the average number of lateral roots level up to 28.7, qualified rate was 33.4%, the qualified seedling production is 89100 plants· hm-2 .
