通过春小麦高产群体的研究,指出了不同混播条件下的群体结构、叶面积指数、穗层厚度等与产量形成的关系,其中,以新克旱9号,克丰3号种植比例为6:4的组合产量最高,比对照增加25.3％,效果最好,能更有效的利用光能、吸收水分和养分,促进同化物的积累和经济产量的形成,达到增产的目的。
Through the research of high-yielding spring wheat population, the relationship between population structure, leaf area index, panicle thickness, and yield formation under different mixed-sowing conditions was pointed out. Among them, the planting proportion of Xinkanyan 9 and Kefeng 3 was 6: 4 The highest combined yield was 25.3% higher than that of the control, with the best effect. It could utilize light energy more effectively, absorb moisture and nutrients, promote the accumulation of assimilates and the formation of economic yield, and achieve the purpose of increasing production.
