摘要
[目的]研究了硅钾矿物肥料对生菜(Lactuca sativa)生物量及相关品质的影响。[方法]采用盆栽试验。[结果]硅钾矿物肥料对生菜具有一定的增产效果;施用硅钾矿物肥料或硫酸钾均能使生菜叶绿素含量增加,但对Vc含量没有显著影响;施用硅钾矿物肥料可以提高生菜中钾的含量,其中,施用高量硅钾矿物肥与对照相比差异显著,但效果不及硫酸钾处理。[结论]硅钾矿物肥料具有部分替代硫酸钾等钾肥的作用。
[Objective] The research aimed to study the application effects of Silicon-Potash mineral fertilizer on biomass and correlative characters of Lactuca sativa.[Method] The pot experiment was carried out.[Result] The results showed that Silicon-Potash mineral fertilizer had an effect on the yield of Lactuca sativa and its chlorophyll content also increased compared with the contrast.Silicon-Potash mineral fertilizer had no effect on Vc content of Lactuca sativa.The potassium content of Lactuca sativa increased obviously by using Silicon-Potash mineral fertilizer or potassium fertilizer.[Conclusion] The Silicon-Potash mineral fertilizer can replace part of the potassium fertilizer in vegetable production.
