摘要
通过对强、中、弱 3种不同长势青麸杨每片复叶上挂肚倍数与肚倍产量关系研究得知 :青麸杨长势与肚倍产量关系很明显 ;在 3种长势中 ,每片复叶上挂肚倍数的多少 ,其总产量虽不一样 ,但无显著差异 ;可是 ,挂肚倍数的多少 ,直接影响单倍鲜重 ,并与单倍鲜重间存在着负相关 ;在同一种长势中 ,每片复叶上挂一个肚倍的单倍鲜重最佳 ,并与挂 2 ,3,4 。
Through the studies on the poganin sumac strong growth,average growth and weak growth,we found that the relationship between the growth of poganin sumac and the weight of gallnut was quite close,Among the three growth forms,the number of gallnusts on each compound leaf was different, but not remarkable. Nevertheless, it was negative interrelated with the weight of single gallnut of the same growth form, the single gallnut's weight of one gallnut on one compoud leaf was the best, and it had remarkable diversity from 2,3,4 or 5 gallnuts on one leaf.
