摘　　要：通过穗光合、生物产量、杂种优势等途径探索了小麦的高产稳产与优质高效。结果表明,穗光合对粒重的贡献约相当于旗叶的1.5倍,是产量形成的重要器官,可以选育出具有"绿穗灌浆"特性的新品系,充分利用穗光合,实现高产目标;在提高茎秆强度的情况下,尽可能地提高植株的生物产量,以获得较高的籽粒产量;充分利用新型不育系,组配强优势组合,生产出杂交种,实现小麦高产新途径。同时利用"通过多穗夺高产,通过少花保优质"的措施,解决小麦的高产与优质的矛盾,实现高产与优质的结合。We want to realize the high yield and high quality potential of the wheat through studying photosynthesis of the ear, biomass, heterosis and etc. The results indicated that photosynthesis of the ear was an important organ for yield formation, and which was equal 1.5 times to flag. We may choose and breed new varieties which have ＂green ear injection＂ characteristic and utilize their ear photosynthesis in order to carry out the objectives of high yield. The planting biomass were improved as far as possible under the situation of improving the stem intensity to gain higher seed output. New dysgenesis should be utilized fully, advantage combined and wheat heterosis used to realize the new approach of wheat high yield. The contradiction of high yield and high quality were solved by utilizing ＂striving for high yields by many ears, guarantee high quality by few flowers＂ to realiz high yield and high quality.
