冬小麦晚播高产独杆栽培研究初报

连续两年的试验结果证明:通过以苗保穗,配合以特定肥水管理措施,构成一套比较完善的独杆栽培技术体系,能够较好地达到晚播不晚熟、重施氮肥不贪青、大群体不倒伏等目的;而且,经济产量形成期群体结构合理、干物质日增量大、净光合生产率高、无效损耗少、经济系数高等特点,是一条晚播高产途径。

THE FIRST REPORT ABOUT THE HIGH YIELD OF THE WINTER WHEAT UNDER THE CONDITIONS OF THE LATE SEEDING TIME AND CULTIVATION DEPENDING ON THE MAIN STEM EARS OF WHEAT IN TERMS OF RESEARCH

The results that is proved by the author by means of the experimentsfor two years are as follows:The cultivation techniques depending on the main stem ears of winterwheat that was founded by Fushan Agrotechnical Station is a set of more perfect technical system of cultivation which is composed by means of thespecific managements in the fertilizer and water to play a supporting roleon the basis of depending on the wheat seedling number to ensure the earnumber.It well solved the problems that the seeding is late but the harvestnot late,that a large number of nitrogenous fertilizer is applied but theripe not late,and that the colony is large but not lodging, ect.,And it hasthe characteristics that the colony structure is reasonable in the time offorming economic yield,that the daily increase of dry materials in quan-tity is large,that the net rate of dry materials produced by photosynthe-sis is high,that the meaningless loss is little,and that the economic coeffi-cient is high, etc., Therefore, it is really a efficacious way that the wheatyield is high under the conditions of the late seeding time. After the cultivation of the main stem ears has achieved success, it even more provesthat the high yield of the winter wheat has many ways. It enriches theresearch content of high yield cultivation and broaden researcher′s filldof vision.
