Spatial variability of organic matter and total nitrogen in tobacco growing soil in the north part of Sichuan province
摘要
Abstract
Spatial variability of organic matter and total nitrogen in north tobacco-growing areas of Sichuan province were studied by using GIS technology and relevant statistical methods. Results showed that organic matter content in the sampled area was between 5.80~42.00 g.kg-1, and total nitrogen content varied between 0.66~2.39g.kg-1. Half variance analysis showed that the block gold coefficient of oil organic matter and total nitrogen were 61.7%and 72.0%respectively, which showed weak spatial autocorrelation. Spatial interpolation showed that soil organic matter content was appropriate while total nitrogen content was higher above average in most places of Wangcang county. Soil organic matter content was relatively low while total nitrogen content was appropriate in Yuanba county. Soil organic matter content was appropriate in central part of Jiange county while relatively low in surrounding areas. Total nitrogen content was at appropriate level in most places of Jiange.关键词
