以5个胭脂萝卜品种为材料,采用田间试验,研究不同施肥处理(施磷、施氮、施钾、施氮和钾、施磷和钾、施磷和氮、施氮磷钾及不施肥)对胭脂萝卜成株期主要性状的影响。结果表明,除色素含量性状外,不同施肥处理对胭脂萝卜成株期株高、根长、地上部鲜质量、地下部鲜质量、叶绿素含量、丙二醛含量及过氧化物酶活性均有显著影响。不同胭脂萝卜品种有不同的需肥特点。施用氮肥能显著提高胭脂萝卜的株高、地下部鲜重、地上部鲜重和叶绿素含量,促进胭脂萝卜的生长,施用磷肥和钾肥对胭脂萝卜主要性状影响不大。在胭脂萝卜施肥中,应主要施用氮肥,不施用或少施用磷肥和钾肥,结合不同品种需肥特性,施用不同量的氮肥。
Five varieties of Radish were used to study the effects of different fertilization treatments (applying phosphorus, nitrogen, potassium, nitrogen and potassium, applying phosphorus and potassium, applying phosphorus and nitrogen, applying NPK and not fertilizing) Effect of Radish on Main Characteristics of Adult Radish. The results showed that in addition to the pigment content traits, different fertilizer treatments had significant effects on the plant height, root length, aboveground fresh weight, underground fresh weight, chlorophyll content, malondialdehyde content and peroxidase activity influences. Different rouge radish varieties have different needs of fertilizer characteristics. Nitrogen application could significantly increase plant height, fresh weight of the ground, fresh weight of the shoots and chlorophyll content, and promote the growth of Radish. The application of phosphate fertilizer and potassium fertilizer had little effect on the main characters of Radish. In rouge radish fertilization, should be the main application of nitrogen fertilizer, phosphate fertilizer and potassium fertilizer are not applied or less, combined with different varieties of fertilizer characteristics, the application of different amounts of nitrogen fertilizer.
