Study On The Growth Effect Of Phoebe Bournei Container Seedling Planted For One Year In Ji’an City

This paper studied the growth effect of different Phoebe bournei container seedling after planting in different fertilization amounts, site types, site factors, by split plot experiment design and correlation analysis, principal component analysis, regression analysis, the quantitative theory I and so on, and took the guan shan forest farm in yong feng county, wu zhifeng forest farm in sui chuan county, bai yunshan forest farm and dong geng forest farm in qing yuang county and so on as the forestation base of Phoebe bournei container seedling. This paper put forward the main technology and measures of management on this basis. The main results are as follows:(1) The Phoebe bournei container seedlings were easy to live in afforest first year and had not sustained seedling stage. The annual growth rhythm of tree height accord with the S-type curve., whose process show the law of "slow-fast-slow". It can grow rapidly in July, August and September, but in the late November it hardly grow.(2) The correlation analysis showed that the correlation coefficient of Phoebe bournei tree height and ground diameter is0.7. The tree height and ground diameter had very significant linear correlation.(3) It evaluate the planting quality of Phoebe bournei container seedlings by principal component analysis. The result showed that2principal components can retained85.58percentage information content.The proportion of first principal component is65.92%. The factor loading of ground cumulative increment that is0.9043is largest. The proportion of second principal component is19.66%. The factor loading of survival rate that is0.7767is largest.(4) It analysis many factors, such as the aspect, slope position and fertilization amount and so on, how to affect the growth of Phoebe bournei. The result showed that the Phoebe bournei can growth better in downgrade than upgrade, shady slop than sunny slop, fertilizer than no fertilizer.(5) This paper study comprehensive influence of the Phoebe bournei growth effect, using multi-factors, according to the method of quantitative theory I. The result showed that the dominant factors of affecting the Phoebe bournei growth were container seedling type, site type, altitude, aspect and canopy density in afforest first year.
