摘要: 晋南石灰性土壤钾素动态研究表明:潮土、褐土土壤速效钾含量均呈下降趋势,其中潮土下降31.25mg/kg,褐土下降15.75mg/kg.土壤质地类型、农业生态区及种植制度不同,土壤速效钾含量下降不同。小麦钾肥试验结果表明:亩施K2SO45~20kg,产量增加52.9~111.5kg/亩,净增收益32.7~62.6元/亩。同时获得了小麦最高产量施肥量和经济最佳施肥量。

关键词: 潮土, 褐土, 小麦, 钾肥肥效

Abstract: The potash status in calcareous soil is studied in the South of Shanxi.The results showed that quick acting potassium level in Chao soil and Cinnanon soil tended to decrease.It decrease 31.25 mg/kg in Chao soil and 15.75 mg/kg in Cinnanon soil.It differed with soil types,soils in different agro ecological areas and soils in different crop rotation system.The results of the potassium fertilizer experiment on wheat indicated that the application of potassium to wheat led to the increase of output,simultaneously,obtained,maximum yield application rate and economic optimum application rate on wheat.

Key words: Chao soil, Cinnanon soil, Potash status, Wheat, Effect of potassium fertilizer
