山白兰引种新区林分生长表现及土壤理化性质的研究

为了探明山白兰引种新区栽培过程中的林分生长效果及其与土壤理化性质的关系，于1978年从云南省引种山白兰到南宁市郊南部进行栽培试验，结果表明：（1）5年生林分平均胸径、树高、立木蓄积量分别为5．48cm、5．57m、25．09m3／hm^2：35年生分别为14．22cm、14．63m、310．88m3／hm^2，显示出幼林期生长迅速、而成熟期生长较缓慢的特点。（2）0～100cm土层的土壤容重为1．112～1．402g／cm^3，总孔隙度为47．47％～60．25％，通气度为10-39％一19．60％，最大、毛管、最小持水量分别为22．50％。42．76％、20．43％～40．69％、18．34...

Summary:为了探明山白兰引种新区栽培过程中的林分生长效果及其与土壤理化性质的关系，于1978年从云南省引种山白兰到南宁市郊南部进行栽培试验，结果表明：（1）5年生林分平均胸径、树高、立木蓄积量分别为5．48cm、5．57m、25．09m3／hm^2：35年生分别为14．22cm、14．63m、310．88m3／hm^2，显示出幼林期生长迅速、而成熟期生长较缓慢的特点。（2）0～100cm土层的土壤容重为1．112～1．402g／cm^3，总孔隙度为47．47％～60．25％，通气度为10-39％一19．60％，最大、毛管、最小持水量分别为22．50％。42．76％、20．43％～40．69％、18．34％～37．93％。（3）土壤pH值为4．02～4．32，有机质含量为6．08％～30．64％，全N、P、K分别为0．58％～1．36％、0．27％～0．36％、2．02％～4．58％，速效P、K分别为0．71～1．56、13．27～40．20ITIg／kg。说明山白兰在广西南宁市郊南部地区引种．其气候及土壤条件是适官的．林分各项牛长量指标基本达到要求．

Paramichelia baiUonii; introduction; growth; physicochemical properties of soil; suburb of Nanning
In order to investigate Paramichelia baiUonii introduced in the new district which has the relationship between stand growth effects and soil properties, we introduced Paramichelia baillonii from Yunnan Province to the southern suburb of Nanning in 1978. The results showed that： （1）The 5 years old stand average DBH, height and volume were 5.48 cm, 5.57 m, 25.09 m3/hm2 respectively, the 35 years old stand average DBH, height and volume were 14.22 cm, 14.63 m, 310.88 m3/hm^2 respectively, which indicated that it grew rapidly during young forest period and slowly during maturity. （2）In the layer of 0～100 cm, the soil bulk density were 1.112～1.402 g/cm^3, total porosity was 47.47%～60.25%, aeration was 10.39%～19.60%, maximum water capacity was 22.50%～42.76%, capillary capacity was 20.43%～40.69%, maximum moisture capacity was 18.34%～37.93%. （3）The soil pH value was 4.02～4.32, organic matter content was 6.08%～3
