Effects of Long-term Non P Fertilizer Application on Yield and Quality in Sweetpotato
利用1980年建立的黄潮土肥料长期定位试验,研究了长期不施磷肥对甘薯产量与品质的影响.结果表明,长期不施磷肥,土壤严重缺磷,致使薯块膨大期迟后、日增重减少,鲜薯产量显著下降(P＜0.05)；与施磷处理相比,不施磷处理薯块干率、淀粉率及蛋白质含量下降不明显(P＞0.05).长期不施磷显著提高薯块可溶性糖和还原糖含量(P＜0.05),并导致甘薯淀粉粘滞力显著降低(P＜0.05)；在长期不施磷肥条件下,不同甘薯品种的产量反应存在显著差异,以此筛选出高耐…查看全部>>
The effects of long-term non-P fertilizer on yield and quality in sweetpotato were studied in long-term stationary field experiment,which was established in 1980 in yellow fluvo-aquic soil .The results showed that long term non P fertilizer treatment would delay the swelling period of sweetpotato storage root and reduce daily output, so as to caused the drop of fresh root yield(P <0. 05) . Compared with application of P fertilizer, the dry matter and star…查看全部>>
