【摘要】 应用ABT生根粉3、6、7号对油松进行了不同浸根时间蘸根造林试验。结果表明,不同时间以60 min和90 min最佳,造林成活率、新梢生长量、新根数平均提高了11.5％、29％、14.5％。3、6、7号ABT生根粉蘸根均能起到提高造林成活率、促进苗木生长、增加地上部分生物量作用。但以3号ABT生根粉最好。更多还原

【Abstract】 Soaking root with No. 3 , 6 and 7 ABT rooting powder in different periods in Pinus tabulaerormis afforestation, results show that 60 and 90 min. are both suitable periods. Survival rate, top growth increment of seedlings and regenerated root number are increased by 11. 5% ,29% and 14. 5% respectively. No. 3, 6 and 7 ABT rooting powder all can increase survival rates, promote seedling growth and increase above ground biomass, among the three, No. 3 ABT rooting powder is best of all.更多还原
