泡桐是我国优良的速生树种之一,是我省平原绿化的优势树种,又是林粮间作的理想树种。我省对泡桐栽培技术的研究较多,但对泡桐立地条件的研究,仅停留在一般定性描述的水平上。如何对泡桐立地条件进行定量评价,目前,国内外尚无报导。为了更好地遵循“适地适树”的原则,充分发挥泡桐的速生优势和林地的生产潜力,一九八五年八月,我们运用数量化理论和计算机新技术,对予 Paulownia is one of the excellent fast-growing tree species in our country, the dominant tree species in the plains of our province, and the ideal tree species for intercropping. In our province, there are many researches on the cultivation techniques of Paulownia, but the research on the site conditions of Paulownia only stays on the level of general qualitative description. How to evaluate the site conditions of Paulownia, at present, there is no report at home and abroad. In order to better follow the principle of “appointing suitable trees” and give full play to the advantages of fast-growing Paulownia and the potential for woodland production, in August 1985 we applied quantitative theory and new computer technologies to
