    摘要:

    分析测试了武平烟区205个土壤样本的质地组成、pH值、有机质含量、全态氮磷钾含量、碱解氮含量、有效磷含量、速效钾含量,并对不同质地土壤各肥力因子间的相关关系进行了分析。结果表明:(1)武平烟区植烟土壤砂土占37.07%、壤土占58.05%、粘土占4.88%,肥力状况良好,pH普遍偏低。(2)不同质地土壤间主要养分含量差异除全钾外均达到极显著水平,全钾达到显著水平,除全磷外其含量均表现为粘土>壤土>砂土,壤土全磷含量最高,砂土最低;pH值表现为砂土>壤土>粘土 (3)砂土:pH值与有机质、全氮、速效钾均呈极显著负相关,与碱解氮呈显著负相关;有机质与全氮和碱解氮呈极显著正相关;全氮与碱解氮呈极显著正相关,与速效钾呈显著正相关;碱解氮与全磷和速效钾呈显著正相关,与有效磷呈极显著正相关;全磷与有效磷、全钾与速效钾均呈极显著正相关。壤土:pH值与全磷和全钾呈显著正相关;有机质与全氮和全磷、全氮与全磷、全磷与有效磷、有效磷与速效钾均呈极显著正相关;全磷与速效钾、全钾与速效钾呈显著正相关。粘土:pH值与全氮呈显著负相关;有机质与全氮呈极显著正相关。砂土各肥力因子之间的相互影响较大,而壤土和粘土各肥力因子间的相互影响较小。

    Abstract:

    The soil texture, Soil pH, Organic Content, the content of total N, P, K and the content of available N, P, K of 205 soil samples from Wuping Tobacco have been analyzed, and the main fertility factors′s correlation of different soil texture also have been studied. The results indicate that sand soil, loam soil and clay respectively account for 37.07%, 58.05%, 4.88%, and the soil nutrient is in good condition, and pH in a low level in Wuping Tobacco area. The differences of main nutrient in different soil texture, except total K′s significant, are very significant. And the content of main nutrient shows that clay>loam soil>sand soil, except total P′s loam soil>clay>sand soil, the level of pH shows that sand soil>loam soil>clay. Sand: pH value has a very significant negative correlation with organic content, the content of total N and available K, and shows a significant negative correlation with nitrogen; organic matter shows highly significant positive correlation with total N and nitrogen; total N shows highly significant positive correlation with nitrogen, and it significantly correlates with available K; nitrogen positively correlates with total P and available K, and highly significantly positively correlates with available P; total P and available P, total K and available K show a highly significant positive correlation. Loam soil: Ph shows significant positive correlation with total P and total K; organic matter shows highly significant positive correlation with total N and total P, which are the same with total N and total P, total P and available P, available P and available K; total P significantly positively correlates with available K, which the same with total K and available K. Clay: pH significantly negatively correlates with total N; organic matter shows highly significant positive correlation with total N. It has great influence in the interrelationship of fertility factors in sand, while less in loam soil and clay.
