摘要
分析了2022年湖北省烟叶主产区4 205份土壤样品的化学性状,并与2011年植烟土壤相关数据进行了比较.结果表明,2022年湖北省植烟土壤pH平均为6.3;有机质含量为25.8 g/kg;碱解氮、有效磷和速效钾的含量分别为121.3、56.70、351 mg/kg.与2011年相比,2022年植烟土壤有酸化趋势,有机质含量总体较稳定,碱解氮含量总体呈下降趋势,有效磷、速效钾含量明显增加.因此,在烟叶生产中,一方面需因地制宜采取措施对土壤酸碱度进行调控,另一方面需要增加有机肥的施用,推广"绿肥压青""深耕"等措施改善烟田土壤的理化性质,同时合理调整烟草专用复合肥的配比.
Abstract
The chemical properties of 4 205 soil samples in the main tobacco-planting areas of Hubei Province in 2022 were analyzed,and compared with the data of tobacco-planting soils in 2011.The results showed that in 2022,the average pH of tobacco-planting soils in Hubei Province was 6.3,the organic matter content was 25.8 g/kg,and the contents of alkali-hydrolyzable nitrogen,available phosphorus and available potassium were 121.3 mg/kg,56.70 mg/kg and 351 mg/kg,respectively.Compared to 2011,the tobacco-planting soil in 2022 had acidification trend,the organic matter content was generally stable,the alkali-hydrolyzable nitrogen content generally showed a decreasing trend,and the available phosphorus and available potassium content increased.Therefore,in tobacco production,on the one hand,it is necessary to take measures to regulate soil acidity and alkalinity according to local conditions,and on the other hand,it is necessary to increase the application of organic fertilizer,promote measures such as"green manure dressing"and"deep ploughing"to improve the physicochemical properties of tobacco soils,and at the same time,adjust the ratio of special com-pound fertilizer for tobacco reasonably.
