一、温度对插条生根的影响根据山西夏县、河南郑州和陕西武功等地的经验,适当提早扦插时间(如从3月中旬提到2月下旬或3月初)能提高成活率。为了分析毛白杨插条的适期,了解越冬埋藏的适温以及春短、气温回升较快对毛白杨生根成活的影响等问题,有必要研究温度对毛白杨生根的影响。试验是用一年生留根苗种条第四、五段插穗,每个处理50株,在灯光温箱中培养,并以加杨为对照。

First, the temperature on the rooting of cuttings According to the experience of Xiaxian in Shanxi, Zhengzhou and Shaanxi Wugong, Shanxi and other places, the appropriate early cutting time (as mentioned in mid-March from late February or early March) can improve survival. In order to analyze the suitable period of Populus tomentosa cuttings, understand the suitable temperature during winter burial, and the effects of spring shortness and rapid temperature rise on the rooting and survival of Populus tomentosa, it is necessary to study the effect of temperature on the rooting of Populus tomentosa. The experiment is to use annual rooting seedling fourth, fifth cuttings, each dealing with 50, incubated in a light incubator, and plus Yang as a control.
