为探究高产小麦一次性简化施肥技术,采用田间试验研究了专用缓释肥、复混肥料及习惯施肥对小麦产量、经济效益、生物重及养分积累量的影响。结果表明,鹤壁和温县冬小麦施肥分别增产26.18%~30.85%和28.11%~32.29%;专用缓释肥促进了冬小麦对氮、钾素的吸收利用,干物质积累量较习惯施肥分别增加2.48%和2.57%,提高了冬小麦千粒重,较习惯施肥分别增产3.27%和3.70%,纯收益分别增加548元/hm2和616元/hm2,可在冬小麦高产区推广应用。
In order to explore a one-time simplified fertilization technique for high-yield wheat, the effects of special slow-release fertilizer, compound fertilizer and conventional fertilization on wheat yield, economic benefit, biomass weight and nutrient accumulation were studied by field experiments. The results showed that winter wheat fertilization in Hebi and Wenxian increased by 26.18% -30.85% and 28.11% -32.29%, respectively. The special slow-release fertilizer promoted the absorption and utilization of nitrogen and potassium in winter wheat, and the dry matter accumulation increased by 2.48% And 2.57% respectively, which increased the 1000-grain weight of winter wheat and increased 3.27% and 3.70% respectively compared with the conventional fertilization. The net income increased by 548 yuan / hm2 and 616 yuan / hm2, respectively, which could be popularized and applied in the high-yielding winter wheat.
