育苗同农业生产一样,主要受生态环境条件特别是气象因子的制约。土壤条件一般可用改土、施肥等措施进行调节和改善,而气象因子的调节和控制比较困难。因而,如何正确掌握气象因子的变化规律,使苗木优质高产,已成为育苗生产中的主要技术问题之一。为此,我们利用白石山林业局新发苗圃的气象资料,结合育苗生产实践,对长白落叶松育苗与气象因子之间的关系进行了分析。
Nursery with agricultural production, like, mainly due to ecological conditions, especially meteorological constraints. Soil conditions generally available soil improvement, fertilization and other measures to adjust and improve, and regulation and control of meteorological factors more difficult. Therefore, how to correctly grasp the variation of meteorological factors and make seedlings of high quality and high yield have become one of the major technical problems in seedling production. For this reason, we use the meteorological data of the newly developed nursery of Baishishan Forestry Bureau, combined with the practice of nursery production to analyze the relationship between the growth of Larix olgensis seedlings and meteorological factors.
