Abstract:
6 nutrient indexes and the integrated soil fertility status of different soil layers from 12 main planting areas of Dendrocalamopsis oldhami were determined and analyzed.The results showed that the nutrient contents in 0-20 cm soil layer were generally higher than those of in the 20-40cm layer, which were more important to the bamboo shoot growth.The variation coefficients of the 6 nutrient indexes ranged from 97% to 1126%, with order of P(A) > K(A) > N(T) > OM > N(H) > pH value.The variations of available P and available K were the biggest, while the variation of pH value was the lest, this was related to the land utilization status for D.oldhami cultivation.Three soil groups were classified according to the results of systemic clustering analysis with the comprehensive values of the soil samples collected from 12 D.oldhami planting areas, i.e., the group I was in south Zhejiang Province with the comprehensive scores over 20; the group II was in south Zhejiang and west Fujian Province with the comprehensive scores from 0914 to 0238; the group III was in southern, eastern and the central parts of Fujian Province with comprehensive scores from -0337 to 0984The 12 D.oldhami production areas were divided into two regions, i.e., Zhejiang Region and Fujian Region.
