摘要
[目的]为了摸清新平县烟区土壤的养分状况,指导农户科学施肥。[方法]对烟区土壤进行取样,分析土壤pH、有机质、碱解氮、有效磷、速效钾、交换性镁、有效硫、有效硼、有效锰、有效锌含量。[结果]60.1%的土壤偏酸,42.55%的土壤有机质含量偏低,38.01%的土壤碱解氮缺乏,36.11%的土壤缺磷,19.06%的土壤缺钾,36.7%的土壤缺硫,6.38%的土壤缺镁,83.51%的土壤缺硼,17.02%的土壤缺锰,60.11%的土壤缺锌。[结论]要重视土壤酸碱度的调节,增施有机肥,施用中微量元素肥。
[ Objective ] The research aimed to find out the soil nutrient status of tobacco growing areas in Xinping County, and to guide scien- tific fertilization. [ Method] Soil pH, organic matter, hydrolytic N, available P, available K, effective Mg, effective S, effective B, effective Zn of tobacco growing areas in Xinping County were analyzed. [ Result] 60.1% soil was acidic. 42.55% soil organic matter was lower. 38.01% soil alkali hydrolytic N, 36.11% soil P, I9.06% soilK, 36.7% S, 6.38% Mg, 83.51% soil B, 17.02% soil Mn, 60.11% Zn were deficient. [ Conclusion ] Attention should be paid to the regulation of soil pH, and the application of organic fertilizer and micro fertilizer.
