摘要：在对31个样区、5-7年生印楝人工林全林普选基础上,提出了印楝药用原料林优树选择方法,优树选择的标准:(1)种子印楝素A和印楝素B的总含量>0.8%;(2)株产果实数与林分优势木平均株产果实数相当或超过林分平均木株产果实数的106%;(3)地径与林分优势木平均地径相当或超过林分平均木地径的16%;(4)无病虫害、旱害和冻害症状。
Based on a three year duration of superior tree screening study that was conducted with 5-7 year old provenance experiment plantations from 31 experimental plots. The selection method and standards of the superior trees for Azadirachta indica plantations as azadirachtin raw material production were proposed as follows： （1） The total content of azadirachtin A and B should be higher than 0.8%. （2） The number of fruits produced per plant should be equivalent to that of the average of dominant trees screened out of the stands or 106% higher than the average yield per plant of the stands. （3） The basal diameter is equal to that of the average of dominant trees or 16% higher than the average trees of the stands. （4） There should be no any symptoms such as diseases or insect pests, drought and freezing injury. The results showed that the selection results from the dominant tree comparison method were basically identical to those of from the average tree comparison method on superior tree selection for pesticide raw material production of A.indica plantations.
