| 摘 要： | 研究了腐殖酸钾对生姜生长、钾素吸收及钾肥利用率的影响。结果表明,生姜植株干物质积累量和钾素积累量随生姜生长发育而增加,变化动态可以用Logistic方程拟合。施用腐殖酸明显提高了根系活力,增加了植株钾素吸收量和干物质积累量,比空白对照增产8.88%。施用腐殖酸钾显著促进了根系生长发育,提高了钾素积累速率和钾素积累量,并最终提高产量,比空白对照增产61.29%,比等量氧化钾对照增产9.92%。施用腐殖酸钾显著提高了钾肥农学利用率和钾肥吸收利用率,而钾素干物质生产效率和钾素收获指数都有所降低。

| Abstract: | The effects of potassium humate on growth,potassium uptake and utilization efficiency of ginger was studied using a sort of potassium humate fertilizer in pool culture experiment.The result showed that the accumulating amount of dry matter and potassium increased with growth stages,which were well fitted to Logistic equation.Humic acid application increased root vigor and accumulating amount of potassium and dry matter,increased the yield by 8.88% compared with CK.Applying potassium humate promoted the growth of ginger root,increased potassium accumulating rate and amount,increased dry matter accumulating rate and amount.Meanwhile,potassium humate application increased yield by 61.29% and 9.92%,compared with CK and the treatment same application rate of potassium momoxide.Potassium humate application increased agronomic efficiency of potassium fertilizers and recovery efficiency of potassium fertilizers significantly,decreased potassium efficiency for biomass production and potassium harvest index. |
