| 摘 要： | 以中薯3号马铃薯品种为试材,研究了不同钾肥用量和缺肥处理对马铃薯产量的影响。结果表明,适量的施用钾肥(8.56kg/667 m2)可以促进马铃薯的营养生长,提高生物产量和分配率,促进地下块茎膨大,从而提高经济产量和商品率,但过量施用钾肥则表现出一定的负效应。而缺肥试验表明,缺施氮肥对马铃薯产量的影响最大,其次是钾肥,再次是磷肥,缺施有机肥影响最小。

| Abstract: | Effects of different K fertilizer usage and fertilizer deficiency on potato yield were studied with the potato Zhongshu 3 as experimental materials in this experiment.The results showed that the vegetative growth,biomass,distribution rate could be promoted,and thereby the economic yield,commodity rates were enhanced when the amount of K fertilizer was 8.56 kg/667 m2.But it showed a negative effect on economic yield with the excessive application of K fertilizer.It also showed that potato yield reduction wer... |
