摘  要：
对江苏海门沿海当年造林的光叶楮生长及生物量调查结果表明:3种立地条件下,造林密度为1 m×1 m时,在林业站苗圃脱盐立地(全盐量0.046%,pH8.15)地上部分生物量干重最大,为8 981.40 kg/hm2,其次在盐碱地东灶港海堤(全盐量0.286%,pH9.09),为6 478.20 kg/hm2,最差在杨树混交林地(全盐量0.098%,pH9.05)为1 846.95 kg/hm2。地下部分的规律与地上部分类似,干重最大是林业站苗圃,为5 158.65 kg/hm2,其次在东港海堤,为1 948.95 kg/hm2,最差在杨树混交林地,为662.40 kg/hm2。总生物量干重最大在林业站苗圃,为14 140.20kg/hm2,其次在东灶港海堤,为8 427.195 kg/hm2,最差在杨树混交林地,为2 509.39 kg/hm2。根系主要分布在10cm浅土层。

摘  要：
The growth condition and biomass of one year old Broussonetia papyrifera plantation was investigated in Haimen,Jiangsu province.The results showed that the aboveground biomass was the highest(8 981.40 kg/hm2) in forestry station nursery(salinity 0.046%,pH 8.15).At Dongzaogang seawall site(salinity 0.286%,pH 9.09),the biomass of Broussonetia papyrifera plantation was 6 478.20 kg/hm2 which was taken the second place.The biomass of Brussonetia papyrisfera mixed Poplar forest(salinity 0.098%,pH 9.05)was the lowest,which was only 1 846.95 kg/hm2.The belowground biomass was similar to that of the aboveground.The maximum of root dry weight was found in forestry station nursery(5 158.65 kg/hm2),which was followed by Dongzaogang seawall(1 948.95 kg/hm2),and the biomass of Broussonetia papyrifera mixed Poplar forest was the lowest(662.40 kg/hm2).Compared the dry weight of the total biomass,the biomass of Broussonetia papyrifera in forestry station nursery was the highest among the three sites which reached 14 140.20 kg/hm2.The biomass of Broussonetia papyrifera in Dongzaogang seawall(8 427.19 kg/hm2) was higher than that of Broussonetia papyrifera mixed Poplar forest 2 509.39 kg/hm2.The roots distributed mainly at depth of 0~10 cm soil layer.
