| 摘 要： | 连续5年在樟子松种子园3个小班进行施肥、灌水、人工辅助授粉,结果表明:在树龄10年生时,施肥可提高母树生长量2.3%～7.1%;灌水对母树生长和结实无显著促进作用,人工辅助授粉可提高球果产量46.6%.待母树树龄12年生后.上述措施可不必再进行.

| Abstract: | Fertilization,irrigation,artificial pollination were conducted on 3 sub-compartment of Pinus sylvestris var.mongolica seed orchard for five years.Result shows that:fertilization can increase growth of mother trees by 2.3%-7.1% with the tree age being 10 years old;irrigation has no significant promotion on growth & fruit of mother trees;artificial pollination can increase the yield of cone by 46.6%.Twelve years old mother trees until after birth,these measures may no longer be conducted. |
