杉木在生长过程中,特别是幼龄期,最易受杉梢螟的危害,使主侧梢枯黄干脱,影响杉木生长,降低材质和利用率,影响杉木种子园结实量。为了防治杉梢螟的危害,今年,我们对嫁接的杉木种子园采用不同浓度的煤油、皂粉混合剂进行防治杉梢螟试验,取得初步效果。 Cunninghamia lanceolata is the most susceptible to the growth of Chinese fir, especially the juvenile. The main shoots are yellow and dry, affecting the growth of Chinese fir, reducing the material and utilization, and affecting the fir seed orchard volume. In order to prevent the damage of the stem borers, we have used the kerosene and soap powder mixtures of different concentrations to control the stem borers in the grafted Cunninghamia lanceolata seedlings this year and achieved initial results.
