为探讨泡桐树开花、结实等生殖生长对其营养生长有无影响和影响程度如何等问题,我们于1980年10月,用3年生兰考泡桐和毛泡桐做试验材料,分四组进行剪除花蕾与对照(即保存花蕾)的对比试验研究。1981年12月再次进行树木生长实测。据1981年4月的物候期观察记载,一般泡桐树(包括对照树)于四月中下旬大量开花,消耗了大量养分,仅有少量叶芽发芽、展叶,到了开花后期才大量展叶,成叶于5月中旬。而剪除花蕾的树,则由于集中了一定量的养分用于枝叶生长,所以提前了12天展叶,成叶时间提前了17天。剪除花蕾不仅可以促进枝叶生
In order to explore the paulownia flowering, fruiting and other reproductive growth of its vegetative growth of the impact and how the degree of impact and other issues, we in October 1980, with 3-year-old Paulownia Paulownia and Paulownia to do the test material, divided into four groups cut buds and Comparative (ie save buds) comparative experimental study. 1981 December once again measured the growth of trees. According to the phenophase observation in April 1981, it was reported that in general, the paulownia trees (including the control trees) bloomed in mid to late April and consumed a large amount of nutrients. Only a few leaf buds were sprouted and leaves were planted. Leaves in mid-May. Cut the buds of the tree, the concentration of a certain amount of nutrients for the foliage growth, so advance leaves for 12 days, leaves into the time advance of 17 days. Cutting buds can not only promote the growth of foliage
