为查明文山州植烟土壤基本状况,提高烤烟施肥的科学性,对文山州2011年142套土样pH值及主要有效养分含量进行了分析,结果表明:(1)全州土壤pH平均值为6.23,总体适于烤烟种植。pH值处于最适区间5.5~6.5的土壤占样品总数的43.7%;(2)全州共有5种土壤类型,pH值平均值顺序依次为:红壤<黄壤<水稻土<紫色土<石灰土;(3)随着海拔升高,土壤pH值呈降低趋势;(4)土壤有机质、速效氮、速效磷及速效钾含量平均值均达到足量标准,适于烤烟种植,但分别有19.72%和16.68%的土壤缺磷和缺钾;(5)土壤pH值与速效氮含量呈显著负相关,与速效磷和速效钾含量则无显著相关性。有机质与速效氮和速效磷含量极显著相关,与速效钾含量显著相关。

Soil pH values and main nutrients in 142 samples collected from Wenshan tobacco growing areas were analyzed. Results showed that:(1) Soil pH values of Wenshan were generally suitable for tobacco cultivation, with average pH value of 6.23. About 43.7%of the soil were in the optimal zone,i.e. pH 5.5~6.5;(2) The average pH values of different soil types were in the following order:red soil<yellow soil<paddy soil<purple soil<calcareous soil;(3) pH values decreased as altitude increased;(4) The average contents of soil organic matter (SOC), available nitrogen (N), available phosphorus (P) and available potassium (K) were sufficient for tobacco growing. However, 19.72%and 16.68%of the soil samples lacked available P and available K respectively;(5)Negative significant correlation of soil pH value with available N was found. Highly significant positive correlations were found between SOC and available N and P. Correlation between SOC and available P was also significant.
