光合产物的积累、分配和运转是小麦高产栽培理论研究的重要内容,也是千斤小麦提高生物产量、经济系数和经济产量达到高产稳产的关键.因此,我们就本院1978～1980年连续三年小麦亩产超千斤的叶片生育特性与光合效率、干物质的积累和分配,植株碳氮营养与干物生产,以及提高生物产量、经济系数等方面的资料进行分析总结,以进一步掌握南方小麦亩产千斤的高产规律. The accumulation, distribution and operation of photosynthetic products are the important contents of the theoretical research on high-yielding wheat and the key to increase yield, economic coefficient and economic yield of high-yielding wheat.Therefore, Yield and dry matter accumulation and distribution, plant carbon and nitrogen nutrition and dry matter production, as well as to improve the biological yield, economic coefficient and other aspects of the data were analyzed and summarized, in order to further grasp the southern wheat yield per kilogram The law of high yield.
