摘要
对2002～2008年肇州县植烟土壤781个样品的养分含量进行了统计分析,结果表明,肇州县植烟土壤速效磷和速效钾平均含量呈明显增加趋势,到2008年土壤速效磷平均含量>40mg·kg-1,速效钾平均含量>200mg·kg-1,烟区土壤中磷和钾含量处于非常丰富的状态;而碱解氮含量呈缓慢增加趋势,土壤碱解氮的平均含量>110mg·kg-1,含量相对比较适中;土壤有机质含量呈下降趋势,植烟土壤有机质平均含量均低于<30g·kg-1,肇洲植烟土壤养分含量状况是有利于烟叶生产和品质的提高。
Nutrient contents of 781 soil samples of flue-cured tobacco fields form 2002-2008 in zhaozhou county were tested. The results showed that contents of available phosphorus and available potassium increased. The current average levels of soil available phosphorus was greater than 40 mg·kg^-1. The current average levels of soil available potassium was greater than 200 mg·kg^-1. Available phosphorus and available potassium were sufficient to tobacco-planted soil in zhaozhou county. The contents of alkali- hydrolysable N increased slowly in zhaozhou county and the average levels of soil alkali-hydrolysable N was greater than 110mg·kg^-1. The content was relatively moderate. But the contents of organic matter decreased, and the current average of soil organic matter was lower than 30mg·kg^-1. The contents nutrient situation of tobacco-planted soil could be beneficial to increase the yield and quality of tobacco leaf in Zhaozhou county.
