目前,提高毛竹林生产力主要从两个方面入手,即改善林分群体结构和进行合理施肥。关于竹林施肥的研究,日本起步较早,比较系统深入,但近期研究较少。我国开展竹林施肥研究较迟,虽已取得初步结果,但不够全面深入。为此,林业部和加拿大国际发展中心(IDRC)都分别与我所签订合同,开展毛竹施肥的研究。本文着重分析氮、磷、钾三要素所起的作用。
At present, raising the productivity of Moso bamboo forest mainly starts from two aspects, that is, improving the structure of forest group and carrying out rational fertilization. On bamboo fertilization research, Japan started earlier, more systematic, but less recent research. Research on bamboo fertilization in our country is relatively late, although initial results have been obtained, but not enough comprehensively and in-depth. To this end, both the Ministry of Forestry and the Canadian International Development Center (IDRC) have signed contracts with me to conduct research on bamboo fertilization. This article focuses on the analysis of the role played by the three elements of nitrogen, phosphorus and potassium.
