龙岩市植烟土壤pH空间分布及其与土壤有效养分的相关性研究
A study of soil pH spatial distribution and its correlation with the available nutrients in tobacco-growing areas of Longyan City
摘要
Abstract
To adjust the acidity of tobacco-planting soil in Longyan tobacco areas, enhance the availability of soil nutrients and promote the growth of high quality flue-cured tobacco, 366 representative tobacco-planting soils were collected and the soil available nutrients and pH values were determined from December 2010 to Jan-uary 2011. The traditional statistic method and geostatistic method were applied to the analysis of the correlation among the elevation difference, the county difference, the spatial distribution, and the relationship between soil pH values and available nutrients. The results show that the spatial distribution of soil pH was strip-shaped and there were two high value areas and two low value areas. To some extent, the pH values of Longyan tobacco areas were determined by exchangeable calcium, effective zinc, effective sulfur and alkaline hydrolysis nitrogen. The influencing order of other available nutrients from high to low was: exchangeable magnesium>available K>effec-tive boron>available P>water soluble chloride>available copper. Alkaline fertilizer should be applied more in low altitudes and the south of Changting County as well as the northwest of Shanghang County; K fertilizer should be applied more in the south of Changting and the northeast of Shanghang; a small amount of Cl fertilizer should be applied in the boundary between Zhongchi, Shifang and Yanqian of Wuping County as well as the boundary be-tween Datong and Xinqiao of Changting; Cl fertilizer should be applied appropriately where its soil pH value is more than 6.5.关键词
