| 摘 要： | 为了解矿物肥料的肥效,采用盆栽试验,研究了矿物肥料硅钾肥对油菜生物量及相关品质的影响。结果表明:矿物肥料对油菜具有一定的增产效果,其中高量矿物肥处理(每千克土施用3 g矿物肥料)比对照(不施任何钾肥)增产13.7%,比硫酸钾处理增产4.2%;施用矿物肥料对油菜叶绿素和维生素C含量没有显著影响;此外,施用矿物肥料可以明显提高油菜中的钾含量,与对照相比差异显著,低量和高量矿物肥处理植株全钾含量分别较对照提高35.1%和54.2%,但效果不及硫酸钾处理,硫酸钾处理植株全钾含量较对照提高95.9%。从在油菜上的应用效果可以看出,矿物肥料可以作为钾肥在生产上应用。

| Abstract: | Pot experiment was used to study the application effects of porous Ca-Si-K mineral fertilizer on rape(Brassica napus L.).The results showed that mineral fertilizer affected the yield of rape.The treatment of mineral fertilizer at high level(add 3g mineral fertilizer per kg soil)showed the most obvious effect compared with other treatments.The yield of rape increased by 13.7% compared to control and by 4.2% compared to the treatment of K2SO4 fertilizer.In this experiment,mineral fertilizer had no effect on contents of chlorophyll and vitamin C in rape.In addition,the potassium content of rape was obviously increased using mineral fertilizer compared to control.It was increased by 35.1% and 54.2% with low and high level of mineral fertilizer,respectively,and increased by 95.9% with K2SO4 fertilizer.Therefore,the Ca-Si-K mineral fertilizer could be used as potassium fertilizer in rape production. |
