Abstract

The soil fertility of Heyuan Central Nursery in Guangdong Province, which had 5 different sites coded A, B, C, D, E,was evaluated with modified Nemoro formula.The correlations between fertility coefficients and seedling growthwere analyzed.Soil texture,bulk density,pH,organic matter,totalN,available N,P andKwere selected as main properties for the integrated quantitative evaluation of soil fertility. Results revealed that the soil fertility coefficient Pmeanof the 5 sites was between 1.06 and 2.48, the Pminwas 0.03- 0.97 and the integrated coefficient p was between 0.66 and 1.65,withobvious differencesexisting in the 5 sites and differentlayersof each site. According to the evaluation result, the fertility of the surface layers(0- 20 cm)of site A, B and D and the subsurface layer(20- 40 cm)of site A was low and all other sites and layers was infertile. Significant positive correlationswere found between height of broadleaved seedlings and soil fertility coefficients Pmeanand p. Single seedling biomasswas observed to be significantly positively correlated to Pmean, Pminand p.Therefore, Pmeanand p could be suitable coefficients of nursery soil fertility and seedling biomass could be a reasonable bio-index to evaluate soil fertility.[Ch, 7 tab. 11 ref.]
