通过大田试验和室内分析方法研究了潮土上钾对两个超高产小麦品种产量及氮、磷吸收效应的影响,结果表明:同一供钾水平下,温麦6号的的增产效果好于兰考906-4;钾与氮和磷之间存在着明显的正效应,而且耐低钾小麦品种更具有促进氮的吸收效应,使得氮、钾之间的相互促进作用表现得更为突出,这在一定程度上保证了作物高产对养分的需要。 The effects of potassium in the Chao soil on the yield and nitrogen and phosphorus absorption of two super-high-yielding wheat cultivars were studied by field experiments and laboratory analysis. The results showed that the yield increase of Wenmai 6 was better than that of Lange 906-4. There is a significant positive effect between potassium and nitrogen and phosphorus, and the low potassium tolerant wheat varieties also have the effect of promoting the absorption of nitrogen, making the mutual promotion of nitrogen and potassium more prominent To some extent, the high yield of crops to ensure the needs of nutrients.
