| 摘 要： | 通过田间试验,研究了贵州高海拔地区氮磷钾配施对小麦产量的影响。结果表明:在氮、磷、钾三要素中对小麦产量影响最大的是钾,不施钾的处理减产811 kg/hm2,减幅22.0%;其次是氮,不施氮的处理减产486 kg/hm2,减幅13.2%;再次是磷,不施磷的处理减产405 kg/hm2,减幅11.0%。小麦施用钾肥可增产446~1095 kg/hm2,增幅为15.5%~38.1%,可增收806.00~1 854.50元/hm2,增产增收效果好。在贵州高海拔地区小麦适宜的施肥配比是:纯N 60 kg/hm2,P2O532 kg/hm2,K2O 122 kg/hm2。 |

| Abstract: | The field experiment was tested to investigate effects of N,P and K balance fertilizer on yield of wheat planted in areas with high elevation.The results showed that the potash fertilizer was the most important fertilizer for wheat yield among N,P and K fertilizer,and the wheat yield with applying K fertilizer could increase 446 ~ 1095 kg/ha and the increase range was up to 15.5%~38.1%,which increased the income of 806.00~1854.50 yuan/ha.The optimum ratio of N,P and K fertilizer for wheat planted in high elevation was 60 kg/ha of pure N,32 kg/ha of P2O5and 122 kg/ha of K2O. |
| Keywords: | wheat potash fertilizer balance fertilization high elevation area Guizhou |
