不同施肥处理对胭脂萝卜主要性状的影响
Effect of fertilizer treatments on the traits of red radish at the adult stage
摘要
Abstract
A field experiment was carried out to investigate the effects of different fertilizer treatments (P fertilizer,N fertilizer,K fertilizer,N+K fertilizers,P+K fertilizers,P+N fertilizers,P+N+K fertilizers,and no fertilizer application) on the traits of five different red radish varieties at the adult stage.The results indicated that,except for the pigment content,plant height,root length,fresh leaf weight,fresh root weight,chlorophyll content,malondialdehyde content and peroxidase activity were significantly affected.Additionally,different red radish varieties responded differently to different fertilizers.N fertilizer could significantly improve the fresh leaf weight,fresh root weight,and chlorophyll content and promote its growth.However,the effects of P and K fertilizers on the trait development of red radish at the adult stage were not obviously.Therefore,when red radish is cultivated,N fertilizer should be applied,and P and K fertilizers are not used or applied at a lower level.Fertilizer requirement characteristics of individual varieties should be considered when different amount of nitrogen fertilizers are applied.关键词
