花岗岩侵蚀劣地马尾松残林改造途径的研究

Study on remoulding road of the remant Masson's pine wood stand on the granitic eroded and inferior land

本研究选择１０种优良速生的牧草、绿肥和薪材树种，采用林间套种的种植方式，组成松草、松肥和松薪混交三种技术措施对花岗岩侵蚀劣地的马尾松残林进行改造。重点研究分析了各改造措施对马尾松生长和土壤理化性质的影响及经济效益的优劣，结果表明，松草、松肥、松薪混交改造花岗岩侵蚀劣地的马尾松残林、见效快，改土保水效果好，在经济上是合理可行的．

This study was alout the reconstruction of Masson's pine inferior standon the eroded and inferior land of granite.It selected 10 kinds of fine pasturage,green manure and fuelwood,made up 3 technical measures with the method of in-tercropping as mixed pine and pasturage, pine and green manure,pine and fuelwo-od.Focus:the research and analysis on the effect of each reconstuctrion measurewith the growthof Masson's pine, the physical and chelnical properties of soil,and their economic benefit.The result shows that mixed pine and pasturage,pineand green manure,pine and firewood to reconstruct the remant Masson’s pinewood stand on granitic eroded and inferior land are of quick effectiveness,goodresult of soil improvement and water conservation as well as efficient on economic benefit.
