【摘要】 选用银荆、南酸枣、杜英、马褂木等２２个速生阔叶树种为试材。在庆元不同立地地段进行不同树种、不同种植密度和不同树种混交方式造林试验，通过连续５年的调查、测试表明，银荆、南酸枣、杜英、马褂木等树种具有早期丰产的特性，采用密植造林４-５年可获得较高的生物产量与经济效益，同时提出了“短轮伐期人工菇木林丰产栽培”模式。更多还原

【Abstract】 22 species of broad - leaved trees, such as Acacia dealbata, Choerospondias aXillrisE]aeocarpus deeipiens and Lidforndton Chinense were selected to apply in afforestation testS ofdifferent tree species, and difterent mixture patterns in different site -- types of Qingyunan. 5years’ investigation indicated that, Acals dealbata. choerospendias axillaris, Elaeocarpus decipiensand LiciodeDdron chinensc had early and high - yield characteristig. The great economic benefitsand higher biological yield could be gained within 4 - 5 years, by adopcation of close plantingtechniques.更多还原
