摘要
采用"3414"肥料效应试验设计方案对甜菜氮、磷、钾肥施用效应及交互作用进行研究。结果表明,氮、磷、钾肥用量和配比是影响甜菜产量的重要因素,氮、磷、钾各养分施用的最高增产率分别为56.0%、13.51%和10.64%;从养分效率看,中氮、中磷和中钾水平利用效果最好;氮、磷、钾肥之间存在一定的交互作用,配合施用能提高肥效和促进甜菜生长,中量水平的养分用量有利于各养分效果发挥。
According to the 3414 experimental design scheme of fertilizer effects,the application effect and interactions of nitrogen,phosphorus,potassium on sugar beet were studied,The results showed that the fertilizing amounts and proportion of N,P and K fertilizer were important factors which affected sugar beet yield.The highest yield rate was 56.0%,13.51% and 10.64%,respectively,by fertilizing N,P and K.According to the nutrient efficiency,the fertilizer application of N,P,K at medium level had the best effect;there were interactions among N,P and K fertilizer,coordinated applications of N,P and K fertilizer could improve fertilizer efficiency and promote sugar beet growth,the nutrient dosage of medium level was propitious to various nutrient effect exertion.
