摘　　要：1995、1996年对尤溪杉木种子园调查结果表明:球果病害在3月15日～4月15日间形成一发病高峰,8月15日～9月15日视气象条件形成次发病高峰。正交试验筛选出的防治组合方案为:加倍燃放多菌灵烟剂,于3月下旬根施896菌剂,4月上旬根施复合肥加过钙,不垦复。The results of investigating the seed orchards of Cunninghamia lanceolata in Youxi in 1995 and 1996 indicated that an attack peak of cone diseases formed between March 15 and April 15 and another one formed between August 15 and September 15 in the light of meteorological conditions.The control combination scheme screened by the orthogonal experiment was as follows:setting off double carbendazol fumicants,applying 896 dosage to the roots in the latter part of March; applying compound fertilizers with calcium superphosphate to the roots in the first ten day period of April;and not cultivating the soil.
