| 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。

| Abstract: | Investigation was carried out to study the yield and tapping panel dryness(TPD)of rubber variety GT1 in the secondary and primary plantations of the first-class type and the third-class type planting land respectively.The results indicated 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 highe(r P<0.01).It is regarded that nutrients deficiency in soil is the main cause in the secondary rubber plantations. |
