小麦新品种‘光明麦2号'高产栽培技术研究

High yield culture technique of new wheat variety 'Guangmingmai 2'

以小麦新品种'光明麦2号'为试验材料,研究了播期和密度及肥料运筹对其产量及产量构成的影响。结果表明,'光明麦2号'在崇明地区的适宜播期为10月25—30日,适宜种植密度(基本苗)为165万/hm^2;高产栽培合理的氮肥施用量为纯氮270 kg/hm^2,氮肥运筹上,应适当后移,最适宜的前后用量比例为6:4。

Field experiments with new wheat variety ＇ Guangmingmai 2＇ were carried out to study elIects oI seeding date, planting density and fertilization technique on the yield and yield components. The result indicated that in Chongming area the suitable seeding date was October 25--30, the appropriate planting density was 1.65 million plants/hm2 or so, the rational pure nitrogen fertilizer rate was 270 kg/hm2, and the optimal ratio of nitrogen fertilizer applied at early stage to nitrogen fertilizer for heading was 6： 4.
