| 摘 要： | Ｌ（２１１）１２防治试验结果表明：一条既能防治杉木叶部病害又能促进杉木生长的综合措施是：修除病枝、松土１５ｃｍ深，平衡施入氮、磷、钾肥（０．５∶２．５∶０．０５ｋｇ／株），百菌清２ｍＬ／株注干，１０ｍｇ／Ｌ赤霉素、５ｍｇ／Ｌ吲哚乙酸、１ｍｇ／Ｌ激动素混合液灌根。处理当年，一年生针叶可获８８．８７％的相对防病效果，单株材积净增长２４．７％；第二年，新针病害的防病效果仍达７１．１３％，单株材积累计净增４２．８４％防病增产作用明显

| Abstract: | In the straight-cross experimental plots, control measures consisting of pruning off infected branches, scarifying the soil, fertilizing the soil with N. P. K adequately, injecting Daconil into the trunk and drenching the soil by the mixture of 10mg/L gihherellins, 5mg/L IAA.and 1mg/L hormone, were effective for controlling the needle diseases and promating the growth of China Fir. From the first year to the second year needle diseases were reduced by 88.87%—71.13% and the growth in volume increased by 24.7%─42.84%. |
