摘要
于2000年在迪庆州小中甸国有林场中心苗圃进行了不同基质和不同肥料配方对高山松苗木高生长影响的育苗试验,结果为:该地区高山松年生长过程可划分为出苗期、幼苗期、速生期和苗木硬化期;基质处理方式和肥料配方对出苗期并无太大影响,温度是决定出苗期长短的主要因素;基质的营养成分和物理结构对苗木根系生长的影响是决定速生期苗高生长的关键因素;就当地泥炭而言,保持其原始结构对苗木前期生长更为有利;T肥和T+K肥配方是最适合高山松生长发育的肥料配方;脱盐处理与否对苗木生长的影响不显著。
The experiment on raising seedlings of Pinus densata Mast by different matrix processing and fertilizer ingredients was done in central nursery of state - owned forestry farm of Xiaozhongdian in Diqing prefecture in 2000. It resulted that there was little influence of matrix processing and fertilizer ingredients on seedling stage, while the temperature was the determinant factor to the length of seedling stage ; the influence of matrix nutrient elements and physical structure on the root system growth was key factors to determine height growth in fast - growth period of seedling. As far as peat in the local be concerned, its original structure was beneficial for the growth of seedling in prophase, and the fertilizer composition of T fertilizer and T ＋ K fertilizer was the most favorable for the growth of Pinus densata Mast ; and the influence of desalinized treatment had nothing to do with the growth of seedlings.
