林木施肥是短轮伐期工业用材林的基础技术措施

Plantation Fertilization-Basic Technical Measures for Short-Rotation Industrial Plantation Management

  • 摘要: 发展短轮伐期工业用材林是缓解我国森林资源危机的有效途径之一,并有助于协调森林的经济利用和生态利用矛盾。受制于自然、社会、经济条件,日前发展工业用材林地区不少土壤肥力不高,养分比例失调;连栽人工林地力衰退异常明显,生产力下降;短轮伐期工业用材林养分消耗大,已有林地肥力不能满足其需求,而混交、轮栽等生物措施恢复地力过程缓慢,难以解决近期林地肥力不足矛盾,故林木施肥与良种选育一样,是培育短轮伐期工业用材林必要的基础技术措施。

     

    Abstract: To develop short-rotation industrial plantation is an useful way to alleviaten the crisis of forest resources China and is useful for the coordination of the contradiction between economic and ecological use of forests. Recently, a lot of land used for developing the short-rotation industrial plantation are of low soil fertility, and the productivity of successive plantation on these lands is decreasing because of the degradation of soil fertility, largely due to the limitation of natural, social, and economic conditions. For consuming up a lot of soil nutrients, the short-rotation industrisl plantation could not absorb enough inherent nutrients from soil for its normal growth. It takes long time to restore soil fertility by biological ways such as mixed cropping and rotation of crops etc., and it is difficult to increase the soil fertility in the near future by these ways, so plantation fertilization, like the application of superior seeds,is necessary to cultivate the short-rotation industrial plantations.
