落叶松喜光、耐寒、生长迅速,材质优良,广泛分布于我国东北、华北、西南高山区。卓资山苗圃1965年育苗,1967年栽植的落叶松有的现已长成椽材,生长速度接近小叶杨,是内蒙高寒地区造林的好树种。落叶松在幼苗期,容易感染立枯病,严重的能造成80%的幼苗死亡。松苗立枯病被认为是一种多病原,发病时间长的复杂病害,是培育松苗的一大难题。卓资山苗圃用毛主席哲学思想指导实践,从提高松苗抗病力入手,逐步摸索出一套在全光条件下,不使用农药有效地防止立枯病发生的育苗方法,成功地培育出大面积落叶松苗,每亩节省药剂防治费4元多,为多快好省地培育松苗提供了新经验。
Larch hi light, cold, rapid growth, good quality, widely distributed in China’s northeast, north, southwest high mountain. Zhuozijishan nursery nursery 1965 nursery, planted in 1967, some of the larches have now grown into rafters, growth rate close to poplar, is a good species of afforestation alpine regions in Inner Mongolia. Larch at the seedling stage, susceptible to blight, severe can cause 80% of the seedlings die. Pine seedling blight is considered as a multi-pathogen, a long time of complex diseases, is to cultivate pine seedlings a major problem. Zhuo Jishan nursery with Chairman Mao’s philosophy guidance practice, from the start to improve the disease resistance of pine seedlings to gradually develop a set of all-light conditions, do not use pesticides to effectively prevent the emergence of blight disease nurturing methods successfully nurtured large Area larch seedlings, pesticides per acre to save more than 4 yuan prevention and control, for more rapid and better training to provide pine seedlings provide a new experience.
