为提高烤烟施肥的针对性,测试分析沾益烟区320个植烟土壤样本的pH和土壤养分状况.结果表明:沾益植烟土壤pH整体适宜,平均值为6.06；pH处于适宜烤烟生长的5.0～7.0的土壤样本占75.3％.不同土壤类型pH高低顺序表现为:新积土＞水稻土＞紫色土＞红壤.土壤pH与有机质、全氮、全钾、有效钙、有效镁、有效铁、有效锰以及水溶性氯离子含量的相关性系数达1％极显著水平.土壤pH分组后,土壤养分含量在组间存在极显著差异.沾益植烟土壤pH为5.5 ～6.5的土壤的有机质、碱解氮、速效钾、有效钙、有效镁、有效铜、有效锌、有效铁、有效锰、有效硫和水溶性氯离子的含量能够满足优质烤烟生长需要,全氮、全磷和速效...

In order to improve the targeted fertilization for flue-cured tobacco,the pH distribution in Zhanyi tobacco planting area was analyzed from 320 soil samples. The results indicated that the pH of Zhanyi tobacco planting soil was generally suitable for tobacco cultivation with a mean of 6.06. The pH between 5.0--7.0 of the soil samples was about 75.3% ,it was good for the growth of high-quality tobacco. The pH of different soil types was in the following order： new alluvial soil 〉 paddy soil 〉 purple soil 〉 red soil. The correlations between ...
