| 摘 要： | 通过盆栽试验,研究了在滴灌施肥条件下不同供磷方式对马铃薯生长、产量、品质的影响。结果表明,施磷处理马铃薯的生物学产量显著高于不施磷处理,而不同供磷方式对马铃薯生物学产量的差异不显著;滴施磷肥处理有利于提高马铃薯块茎中的磷质量浓度;马铃薯块茎产量以50%磷肥基施、50%磷肥分10次追施的处理最高,且其商品薯率也最高,达到88.96%,比不施磷肥的对照处理高出6.54%;不同供磷方式对马铃薯块茎中的淀粉含量、干物质含量等品质指标的影响表现为差异不显著。

| Abstract: | A pot experiment was carried out to evaluate the effects of P fertilizer application methods on the growth,tubers yield and quality of potato under drip fertigation system.The results obtained were as follows: under this experiment condition,compared with no phosphate fertilizer treatment,the phosphate treatment could significantly increase biomasses of potato,then there had no different among the five treatments in phosphate application methods.The P fertilizer applied by drip fertigation increased P conce... |
