沿海木麻黄、湿地松混交和黑松林改造试验

通过在滨海沙地上营造木麻黄、湿地松混交林，林农轮作，幼林施肥以及对山地黑松低产林改造等技术措施。结果表明。改造后的林分，不但可以充分利用林地生态资源，提高林分的生产力和收获量，扩大造林成效，而且对改善生态环境也有特殊的效益。

The Experiments of the Mixture of Casuarina equisetifolia and Pinus elliottii and the Remake of Pinus thunbergii Forests on the Coast

By means of the technical measures of constructing mixed forests of Casuarina equisetifolia and Pinus elliottii on the coastal sand,rotating forests and farm crops,fertilizing young forests and remaking low yield forests of Pinus thunbergii in hilly areas,the results indicate that the remade stands can not only fully use the ecological resources of forest land ,increase the productivity and yield of the stands and expand the planting effect but also possess a special benefit for improving the ecological environment.
