在人工林更新中,首先应当研究提高人工幼林成活率的方法,而造林成活率取决于诸多因素。其有效方法之一就是用生长激素处理实生苗与扦插苗的根系。所使用的生长激素是萘蜡乙酸钾,异丁酸,ЭЭЭ,异生长素(吲哚乙酸)及其吲哚乙酸的钾盐。从1980至1986年,西西伯利亚地区林业土壤化验室在营造人工幼林时已进行了27个 In the regeneration of plantations, we should first study ways to improve the survival rate of young plantations, and the survival rate of afforestation depends on many factors. One of its effective methods is to use the growth hormone treatment of seedlings and cutting seedlings root system. The growth hormone used is naphthalene potassium acetate, isobutyric acid, ЭЭЭ, isoflavones (indole acetic acid) and its indole acetic acid potassium salt. From 1980 to 1986, the Forestry and Soil Laboratory in West Siberia has conducted 27
