Study on Variability of Soil Nutrient Characteristics of Moso Bamboo in Jiangxi Province

摘要

The distribution characteristics of soil nutrient of bamboo forests in Jiangxi Province 6 main producing bamboo counties were studied. The results showed that the soil nutrient contents decreased with depth. The soil organic matter contents in Sanzhualun (SZL) and YangLing bamboo forest were obvious higher than others. The 0-10cm content available nitrogen in SZL and total nitrogen in Fengxin Jindong (FXJD)was the highest. The soil total nitrogen and available nitrogen of 10-30cm and 30-50cm. in SZL were the highest, while these of 10-30cm were the lowest in Tonggu Paibu (TGPB) and Tonggu Daixi (TGDX) and that of 30-50cm in SZL. The differences of soil available phosphorus were a few in TGDX and Yifeng Shuangfeng (YFSF), and the changes were 3.33-4.06 mg kg-1 and 3.86-4.42 mg kg-1. The soil available potassium of 0-10cm and 10-30cm layer in SZL bamboo forest were respectively 60.33mg kg-1 and 35.78 mg kg-1 and both were the highest. In 30-50cm soil layer, the soil available potassium content was the highest in TGDX, while the lowest in YFSF. Analysis of variance showed that the differences of soil organic matter and available nitrogen content were very significant between the layers of forests. The differences of total nitrogen and available potassium of 10-30 cm and 30-50cm were very significant There were no significant differences of soil available P and surface available K content.
