本文研究了6种药剂处理苗木根系对苗木生根成活的影响,结果表明:高效催根素、苹果酸(1%)、柠檬酸(1%)和KH_2PO_4(1%～3%)对兴安落叶松1-1型苗生根成活有显著促进作用,玉米素(50ppm和100ppm)处理效果并不显著,α萘乙酸(50～500ppm)处理对苗木生根成活有显著抑制作用,高浓度(500ppm)可将苗木全部致死.玉米素和高效催根素对樟子松1-1型苗生根成活有显著促进作用,其它药剂有抑制作用.6种药剂处理对樟子松1-1型苗当年生长都有不同抑制作用.
In this paper, the effects of 6 kinds of agents on the rooting of seedlings were studied. The results showed that the effect of 6 kinds of agents on the rooting of seedlings was better than that of the control. 1-1 type seedling rooting had a significant promotion effect, zeatin (50ppm and 100ppm) treatment effect is not significant, alpha naphthalene acetic acid (50 ~ 500ppm) treatment of seedling rooting survival significantly inhibited the high concentration (500ppm) All the seedlings were lethal.Extract of zeatin and Hyperstimulus significantly promoted the rooting of Pinus sylvestris var. Mongolica 1-1 seedlings and inhibited the growth of other seedlings. Six kinds of chemical treatments had significant effects on the growth of 1-1 seedlings of Pinus sylvestris var. Mongolica Different inhibitory effects.
