Abstract

Provided is a method for transforming a female plant populus forest. The method comprises the following steps of (1) male plant populus seedling cultivation, (2) seedling outplanting, (3) interlayer transforming, (4) cultivation of shade-tolerance tree varieties, (5) compound management; the method for transforming the female plant populus forest has the advantages that not only can populus catkinspreading be reduced, one part of populus catkins is retained within the forest, thereby reducing the breeding of pests and diseases in the forest through the transforming method, but also the moderate illumination can be provided for the hade-tolerance tree varieties in the forest.

Description

technical field

[0001] The invention relates to the technical field of forest transformation, in particular to a method for transforming female poplar forests. Background technique

[0002] Poplar is an important timber species. Most of the species used in early poplar afforestation are female plants such as 69 poplar and 72 poplar. The mature female plants mature and crack from late April to mid-May every year, and poplar catkins fly everywhere, which has serious ecological and environmental problems; Relatively few and similar biological characteristics, the genetic diversity of the original poplar forest is monotonous, and the ecology is fragile, which may easily lead to the problem of increased pests and diseases; There is a conflict with the key period of growth of shade-tolerant tree species under the forest, which seriously affects economic benefits.

[0003] At present, early female poplar forests have entered the stage of renewal and transformation. In some areas,...
