在相同立地条件下，分别对兰考泡桐林分、四旁树和孤立木样木（包括依靠不定芽自然接干的１５０株和人工接干的３０株）与接干有关的生长因子进行实测，并建立兰考泡桐接干形率与主要生长因子的数学模型；不同栽植方式对接干形率、第一接干高均有显著影响；第一接干高与苗高呈负相关，但相关性不显著；第一接干发生时的树龄以３～４ａ对接干形率的影响最佳，５ａ以后接干效果较差．同时对兰考泡桐不定芽接干各种树形图谱及其在各栽植条件下所占的比例、兰考泡桐第一接干发生时的树龄分布及林分、四旁树、孤立木条件下的相应接干方式等问题进行了探讨．
Under the same site conditions, we measured the growth factors of L. klabriifolia stands, four-sided trees and isolated wood-like woods (including 150 stems and 30 stems) The mathematical model of the dry-forming rate and the main growth factor was established. The dry-jointing rate and the first dry-weight height were significantly affected by different planting methods. The dry weight of the first connection was negatively correlated with the seedling height, but the correlation was not significant ; The first dry when the tree age to 3 ~ 4a docking dry rate of the best, less effective after receiving the stem 5a. In the meantime, the tree-type map of adventitious buds of G. pampataceae and its proportion under each planting condition, the age distribution of the first jointing of L. patricia, and the corresponding extension of stands, Methods and other issues were discussed.
