塔里木河垦区原是胡杨、灰杨的故乡。由于过度的毁林垦荒和樵砍,目前农区已无成片的胡杨、灰杨林。小片次生林是近几年保护下来的。为搞好垦区内的林木建设,加速灰杨育苗,1984年重点进行了灰杨扦插育苗试验,做到当年育苗当年出圃,为大面积造林提供苗木。 灰杨(P、Pruinosa)树杆通直,木质白细,材质好,生长点旺,病虫危害较轻,它耐盐碱,在土壤含盐1—4.5%,PH7—9的碱性土壤上生长正常,耐水、耐旱,耐脊薄,抗风沙,是我垦区适应性最强的树种之一。1984年春在团林管站进行了以普通磷肥水浸液处理插穗,以企达到以下两个目的:
Tarim River reclamation area was originally poplar, gray poplar’s hometown. Due to excessive deforestation reclamation and firewood cut, the current agricultural areas have no film Populus, gray Yang Lin. Small piece of secondary forest is protected in recent years. In order to improve the forest construction within the reclamation area and speed up the growth of aspen and poplar, in 1984 the focus was put on the cuttage and seedling raising experiment of aspen and poplar, so that when the seedling was out of nursery year, seedlings were provided for large area afforestation. Poplar (P, Pruinosa) straight through the tree stems, white wood, good material, growing point, less harmful pests, it is saline-alkali soil in the salt 1-4.5%, PH7-9 alkaline soil On the growth of normal, water, drought, spine resistance, wind sand, is one of the most adaptable species of reclamation trees. The spring of 1984 in the Tuanlin tube station to ordinary phosphate fertilizer flooding cuttings to enterprises to achieve the following two purposes:
