| 摘 要： | 对广西4个国有林场不同种植条件下桉树人工林土壤养分进行测定,分析不同坡度、代数、林龄、种植模式和前作等因素对土壤养分的影响.结果表明,随林地坡度的增大,土壤养分含量先下降后升高,表现出缓坡地养分含量最高,其次为险坡地,陡坡地最低;土壤有效P含量随着林龄增加而显著下降,且连栽代数越多,水解性N、交换性Ca和交换性Mg等含...

| Abstract: | The effects of planting conditions including slope,generation,age,planting patterns and preceding crops on soil nutrients in Eucalyptus plantations were studied in four state-owned forest farms of Guangxi Province.The results were as follows:(1) The soil nutrient contents first reduced and then rose along with the increasing of surface gradient,which showed that the order of soil nutrients content in different slopes were gentle slope,dangerous slope and slope steep in turn.(2) The available P content decre... |
