| 摘 要： | 试验采用氮磷钾的不同组合,对氮磷钾施用量的配比与东北半干旱区大豆产量间的关系及土壤水分效应的影响进行了研究。结果表明,当磷肥施用量为144kg·hm-2、钾肥施用量为216kg·hm-2、氮肥施用量发生变化时,以氮肥施用量为60kg·hm-2的处理产量最高;而当氮肥施用量为180kg·hm-2、钾肥施用量为216kg·hm-2、磷肥施用量发生变化时,以磷肥施用量为192kg·hm-2的处理产量最高。不同氮磷钾配施对土壤水分含量也有很大的影响,其中当磷肥施用量为144kg·hm-2、钾肥施用量为216kg·hm-2、氮肥施用量为120kg·hm-2的处理,能更好地促进作物对土壤水分的高效利用。

| Abstract: | The experiment adopts the different ratio of N, P and K fertilizer, and the relationship of the optimum ratio of fertilizer, soybean yield and soil water has been studied in semiarid district of northeast. The testing results show: when P fertilizer is 144 kg·hm-2 and K fertilizer is 216 kg·hm-2, N fertilizer is 60 kg·hm-2, soybean yield is the highest; when N fertilizer is 180 kg·hm-2 and K fertilizer is 216 kg·hm-2, P fertilizer is 192 kg·hm-2, soybean yield is also the highest. There is also the very biggest effect to soil water on the different ratio of N, P and K fertilizer, when P fertilizer is 144 kg·hm-2 and K fertilizer is 216 kg·hm-2, treatment of N fertilizer is 120 kg·hm-2 that can promote the high use of the crop to soil water. |
