    摘要:

    该研究选择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3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高低。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,其经济上是合理可行的。

    Abstract:

    This study deals with reconstruction of Masson’s pine inferior stand on eroded and inferior land of granite.10kinds of fine pasturage,green manure and fuelwood were selected, to make up 3 technical measures with themethod of intercropping which are mixed pine and pasturage,pine and green manure,pine and fuelwood. The emphasis is placed on studying and analyzing the effect of each reconstruct io n measure on the growth of Masson’spine,the physical and chemical properties of soil,and economic benefit;The result shows that mixed pine and pasturage, pine and green manure, pine and fuelwood to reconstruct Masson's pine inferior stand in eroded and inferiorland of granite has quick effectiveness,good result of soil improvement and water conservation as well as effect oneconomic benefit.
