摘　　要：以钢渣硅肥为试材,采用田间小区试验及室内分析相结合的方法,研究了在白菜种植过程中施用硅肥对白菜产量、抗病性和土壤有效硅含量的影响,以期为硅钙肥在白菜种植中的施用提供参考。结果表明:硅肥能够有效抑制土壤中的有害病菌,降低白菜植株的感病率,霜霉病感病率平均低3.48～7.54个百分点,软腐病感病率平均低2.65～6.13个百分点。硅肥能够促进白菜生长,增加叶绿素含量,提高产量,平均增产率6.25%～8.01%。在连续施用硅钙肥的情况下,白菜的主要生育期土壤有效硅含量均是施用硅钙肥处理明显高于CK,差异显著。Steel slag silicon fertilizer was used as test material,the effects of applying silicon fertilizer on Chinese cabbage yield,disease resistance and soil available silicon content during Chinese cabbage planting were studied by field plot experiment and indoor analysis in order to provide reference for the application of calcium silicon fertilizer in Chinese cabbage.The results showed that the silicon fertilizer could effectively inhibit harmful bacteria in the soil,reduce the infection rate of downy mildew disease of the Chinese cabbage,reduce the downy mildew disease average by 3.48-7.54 percentage points,reduce the soft rot disease average by 2.65-6.13 percentage points.Silicon fertilizer can promote the growth of Chinese cabbage,increase the content of chlorophyll,improve the yield by 6.25%-8.01%under the continuous application of silicon calcium fertilizer,in the main growth period of Chinese cabbage,in soil,the content of available silicon treated by calcium silicate fertilizer treatment was significantly higher than that treated by CK,and the difference was significant.
