摘　　要：为明确分期施肥对马铃薯产量和品质的影响,总结出马铃薯合理施肥技术,本试验以马铃薯新品种‘兴佳2号’为材料,采用随机区组设计,研究了分期施肥对马铃薯株高、茎粗、叶绿素含量、产量和品质性状的影响。结果表明:分期施肥对提高马铃薯株高和茎粗有一定效果,T9的株高最高,相比对照提高了14.3%,T6的茎粗值最高,较对照增加了14%;在块茎形成到块茎成熟期,有7个处理的叶绿素含量高于对照;在产量方面,有7个处理的产量高于对照,其中产量最高的是T6,产量为38460 kg/hm^(2),比对照增产9%,且与对照间差异显著;在品质方面,分期施肥各处理的VC含量相比对照均有所增加;有8个处理的淀粉含量均高于对照。结果表明:合理分期施肥不仅能提高马铃薯单产,而且还可改善马铃薯部分品质。The paper aims to clarify the effects of fertilization by stages on potato yield and quality, and summarize rational fertilization techniques. The randomized block design was used to study the effects of fertilization by stages on potato plant height, stem diameter, chlorophyll content, yield and quality traits using a new potato variety‘Xingjia 2’as the material. The results showed that fertilization by stages could improve the plant height and stem diameter of potato. Compared with the control, the plant height of T9 was the highest and increased by 14.3%, and the stem diameter of T6 was the highest and increased by 14%, respectively. The chlorophyll contents of 7 treatments were higher than the control from tuber formation to tuber maturity. The yields of 7 treatments were higher than that of the control, and the highest yield was T6 of 38460 kg/hm^(2),increased by 9% compared with that of the control. Concerning the quality, the VC content of potato increased in all fertilization by stages treatments. The starch contents of 8 treatments were higher than that of the control.These results suggest that the rational fertilization by stages could not only increase the yield but also improve the quality of potato.
