摘　　要：对甲等宜林地二代胶园和丙等宜林地一代胶园GT1品种橡胶树产量和死皮病率的调查结果:甲等宜林地二代胶园的干胶产量极显著(P<0.01)地低于丙等宜林地一代胶园;而死皮病率极显著(P<0.01)地高于后者,分析认为主要原因是二代胶园土壤营养不足。Investigation was carried out to stndy the yield and tapping panel dryness（TPD）of rubber variety GT1 in the second- ary and primary plantations of the first-class type and the third-class type planting land respectively. The results indicat- ed that the yield of dry rubber in the former plantation is greatly lower than that of in the latter above mentioned（P〈 0.01 ）, while TPD rate is significantly higher（P〈 0.01 ）. It is regarded that nutrients deficiency in soil is the main cause in the secondary rub- ber plantations.
