摘要
对山乌桕播种育苗定苗后保留不同株数(67株/m^2、44株/m^2、33株/m^2、25株/m^2、20株/m^2)育苗对比试验,结果表明:山乌桕育苗以44株/m^2定苗最适宜,1年生幼苗平均地径达1.24cm、平均苗高达229.89cm、主根平均长度达33.58cm、>5cmⅠ级侧根平均条数达10.29条、Ⅰ、Ⅱ级苗百分率达81.7%、Ⅰ、Ⅱ级苗产量21.79万株/hm^2。
the number of different retention of Sapium discolor seeding singling seedling (67 strains/m2 , 44 strains / m2 , 33 strains /m2 , 25 strains /m2 , 20 strains of/m2) seedlingcontrast test, results show that: Sapiurn discolor seedling with 44 strains of/m2 establishing the most appropriate, 1 year seedling average diameter of 1.24 cm, average seedling up to 229.89 cm, the average length of 33.58 cm of root, lateral roots ≥ 5 cm 1 average numberreached 10.29, I, II grade seedling percentage reached 81.7%, I, II grade seedling yield of 217900 strains of/hm2.
