在不影响正常抽穗扬花的情况下,进行岳优9113播插期试验,研究不同播插期对岳优9113农艺性状及产量的影响。结果表明:播期推迟,岳优9113全生育期缩短;移栽期推迟,全生育期延长。在6月13,18,23,28日4个播种期水平中,以6月18,23日播种穗粒结构最优,产量最高;在7月15,20日2个移栽期水平中,以7月15日移栽产量最高,但差异不显著;在8个处理中,以6月23日播种、7月15日移栽产量最高。认为岳优9113在岳阳作双晚栽培,以6月20—23日播种、7月20日前移栽、秧龄28 d以内为宜。
Without affecting the normal heading and flowering, Yueyou 9113 sowing date experiment was conducted to study the effects of different sowing dates on the agronomic characters and yield of Yueyou 9113. The results showed that the sowing date was shortened, the whole growth period of Yueyou 9113 was shortened, the transplanting period was delayed and the whole growth period was prolonged. Among the four sowing dates on June 13, 18, 23 and 28, the grain structure was the best on the 18th and the 23rd June. The highest grain yield was obtained at the two transplanting levels on July 15 and 20, The transplanting output was the highest on July 15, but the difference was not significant. In the 8 treatments, the transplanting output was the highest on July 23 and the sowing on June 23. Yueyue 9113 was considered as double crop cultivation in Yueyang, sown on June 20-23, and transplanted before July 20, within 28 days of seedling age.
