摘　　要：对国审小麦品种济麦22号进行生物学栽培试验,采用顺序排列、2次重复试验设计.结果表明:①播期在越冬以前≥0℃积温为558.4～712.1℃,为最佳播种期;②各叶龄期的出叶速度是倒1～4叶需9.6d,冬前叶为5.6d,越冬期为34.7d;③10月1日前播种的在越冬期前出现分蘖高峰;④早播的穗分化时间早,穗分化的历期长,利于大穗形成;⑤从干物质积累看,10月1日之前播种均高于其他各期,平均为1 556.9kg/667m2;⑥灌浆速度以9月24日至10月8日播种的为高,千粒质量高.在本试验条件下,济麦22号在9月下旬—10月中旬播种,因苗管理,可获得理想产量.The state approved wheat variety of Jimai 22 was studied in biological cultivation experiment, with order and the second repeat test design, results showed that： ①In the winter before sowing≥0℃ accumulated temperature at 712.1--558.4 ℃, for the most good sowing; ②The age out of the leaf speed is： down 1 to 4 leaves, to be 9.6 d, before winter leaves 5.6 d, wintering period of 34.7 d; ③10 May / planted before 1 before the emergence of tillers in winter peak; ④Earlier differentiation of early sowing of the spike, spike differentiation of duration longer conducive to the formation of large panicle; ⑤Watch from the dry matter accumulation 10 month/1 were higher than the other before the sowing period, an average of 1 556.9 kg/667 m^2 ; ⑥Filling rate to 9/24--10/8 range for the high seeding, high grain weight. In the conditions of this study were sowing in late Sept. to mid-Oct. , with good seedling management, Jimai 22 can reaches good yields.
