| 摘 要： | 采用田间试验方法研究了不同钾肥品种和用量对花椰菜养分吸收和分配的影响.结果表明,钾肥可提高花椰菜钾和钙含量,边叶、花轴-花枝含磷量,降低花椰菜各部位含氮量和边叶镁含量.与硫酸钾比较,氯化钾处理花椰菜含氮量、边叶、花轴-花枝含钾量、花球钙镁含量高,但边叶的钙、镁含量较低.氯化钾对钾素运输到花蕾有抑制作用,花蕾含钾量低于硫酸钾处理,对经济产量产生不良影响.硫酸钾处理的铁、锰含量高于氯化钾,而氯化钾处理花球微量元素含量有高于硫酸钾处理的趋势.施钾花椰菜对N、P、Ca有富集效应;氯化钾和镁吸收之间有拮抗作用存在,而硫酸钾处理养分含量降低可能是由于增产产生稀释效应所致.硫酸钾提高微量元素营养体吸收量效果优于氯化钾,但低量氯化钾比硫酸钾有利于花器官养分积累.

| Abstract: | The field experiment was conducted to study the effects of different rates and source of K on nutrient uptake and partition of cauliflower.The results indicated that the K application could increase K and Ca content of cauliflower,P content in side leaves and stalks while reducing the N content in all tissues,and the Mg content in side leaves.Compared with SOP,the N content of cauliflower,K content on side leaves and stalks,Ca and Mg content in head were higher in MOP treatments while the Ca and Mg content were lower.The K content in florets of cauliflower with MOP were lower than that with SOP implied that MOP hindered K translocation,which certainly imposed negative impacts on the production of economic yield.Fe and Mn content of cauliflower with SOP were higher over MOP treatments.The micro-element contents in cauliflower head with MOP was higher than that with SOP.K fertilization enhanced the N,P Ca uptake.There had an antagonism between MOP and Mg uptake.The decrease of cation concentration at SOP treatment were due to the depletion effect of larger yield increments.The effects of SOP on increasing micro-element uptake was better than MOP while MOP at low rate was more favorable for the accumulation of micro-elements in florets of cauliflower. |
