The Application Effects of Silicon-calcium-potash Mineral Fertilizer on Rape(Brassica napus L.)

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.
