| Abstract: | Objective]Effects of different phosphorus sources application on growth and nutrient accumulation of Brassica alboglabra L.H.Bailey was explorded.Method]A pot experiment was conducted to investigate effects of different phosphorus sources (citrate-soluble phosphate fertilizer and water-soluble phosphate fertilizer) application on vegetative growth phase in acid red soil on Chinese kale growth ,nutrient accumulation and soil physical and chemical properties.Result]Application of water-soluble phosphate liquid fertilizer had positive effects on the Chinese kale height,bolting stem diameter,biomass and nutrient accumulation of N,P and K.Conciusion] Application of water-soluble phosphate liquid fertil-izer was advantageous to increase Chinese kale N,P,K accumulation.Meanwhile,it could significantly increase the content of available P in soil and improve the ability of soil supplying nutrient . |
