| 摘 要： | 本研究是在盆栽试验条件下,通过滴灌施肥系统施用四种不同氮肥,以了解不同氮肥对马铃薯生长及块茎产量、品质的影响。试验所选用的氮肥有:尿素、氯化铵、硫酸铵、硝酸铵。结果表明:在滴灌施肥条件下,尿素在促进马铃薯植株营养生长方面所起的作用优于其它3种氮肥;滴施4种不同氮肥影响马铃薯块茎对N、P、K、Ca、Mg等养分的吸收;硝酸铵在提高马铃薯块茎产量、降低还原糖含量方面效果明显。

| Abstract: | Nitrogen is one of the most important nutrients for potato growth.A pot experiment was carried out to evaluate the effects of different nitrogen fertilizers(urea,ammonium chloride,ammonium sulphate,and ammonium nitrate) on the growth,tubers yield and quality of potato under drip fertigation system.The results obtained were as follows:compared with the control treatment,nitrogen drip fertigation could significantly increase the yield of potato,and the role of urea was superior to other three kinds of nitroge... |
