摘要: L12(211)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%.

Key words: NEEDLE DISEASE CONTROL, STRAIGHT-CROSS EXPERIMENT, CONTROL MEASURES
