摘　　要：为探索土壤酸化环境下的花椰菜高产优质生产措施,以花椰菜为试材,设置氰氨化钙、NCD-2微生物菌肥处理,以不施用肥料为对照,试验设W1(667 m^(2)施用氰氨化钙20 kg配施菌肥2.5 kg)、W2(667 m^(2)施用氰氨化钙40 kg配施菌肥2.5 kg)、W3(667 m^(2)施用氰氨化钙60 kg配施菌肥2.5 kg)3个处理,研究对土壤pH值、有机质含量及花椰菜生长、产量、品质的影响。结果表明,种植花椰菜前25 d每667 m^(2)施用氰氨化钙20~60 kg,种植时基肥中配施NCD-2微生物菌肥2.5 kg的处理,对土壤pH值、土壤有机质含量、花椰菜产量及品质均有显著提升;其中,处理W3的效果最优,土壤pH值提升0.71,土壤有机质含量提升5.90%,增加花椰菜产量15.66%,且花球的维生素C、蛋白质、可溶性糖、粗纤维含量均提高10.68%以上。在土壤酸化环境下,施用氰氨化钙后配施NCD-2微生物菌肥技术可在花椰菜生产上推广。In order to explore the measures of high yield and good quality production of cauliflower under soil acidification,the Calcium cyanamide and NCD-2 microbial fertilizer were used as materials,and the control treatment without the application of Calcium cyanamide and NCD-2 microbial fertilizer was used,the effects of three treatments(W1:applying 20 kg Calcium cyanamide and 2.5 kg microbial fertilizer in every 667 m^(2) soil,W2:applying 40 kg Calcium cyanamide and 2.5 kg microbial fertilizer in every 667 m^(2) soil,W3:applying 60 kg Calcium cyanamide and 2.5 kg microbial fertilizer in every 667 m^(2) soil)on soil pH,organic matter,growth,yield and quality of cauliflower were studied.The results showed that 20-60 kg Calcium cyanamide per 667 m^(2) was applied 25 days before cauliflower planting and 2.5 kg NCD-2 microbial fertilizer was applied in basal fertilizer,soil pH,soil organic matter,cauliflower yield and quality were significantly increased,among which treatment W3 was the best,soil pH increased 0.71,soil organic matter content increased 5.90%,the yield of cauliflower was increased by 15.66%,and the contents of vitamin C,protein,soluble sugar and crude fiber were increased by more than 10.68%.The technique of applying NCD-2 microbial fertilizer after 25 days of application of Calcium cyanamide fertilizer under acidified soil environment is worth popularizing in cauliflower production.
