摘要
2010年在兴山全县选取1 995个植烟土壤样品进行分析,并与2000年土壤测定结果进行对比,研究兴山县优质烟叶产区(烟区)植烟土壤养分动态变化情况。结果表明,全区土壤有机质含量有所上升,但呈现两级分化趋势,土壤中全氮和碱解氮含量下降,土壤中全磷处于中偏低状态,全烟区普遍缺硼;兴山县烟区应根据"持续控氮、适度增磷,全面补硼"的原则进行施肥调整。
1995 entries soil samples in the county in 2010 were selected to analyze,and then were compared with the 2000 years＇ to study the dynamic changes of soil nutrients in Xingshan tobacco producing areas; the soil organic matter content increased in the region, but it presented the trend of polarization, soil total nitrogen and nitrogen content decreased, total phosphorus in the soil stayed in the low state, boron was rifeness lack in the area. Xingshan areas should adjust fertilizing based on ＇Continuous control of nitrogen, moderate increase in phosphorus, boron full comnlement＇.
