播期对信麦69生长发育及产量构成的影响
|
摘要
为确定小麦(Triticum aestivum L.)新品种信麦69在河南省信阳市的适宜播期,通过设置10个不同播期研究播期对小麦生育进程及其产量构成的影响。结果表明,随着播期推迟,小麦叶龄、分蘖数、单茎鲜重、单茎干重、株高、穗粒数、灌浆速率、穗长和产量呈先升高后下降的趋势;信麦69在信阳市最适宜播期为10月25—30日。
In order to evaluate the suitable sowing date of new wheat varieties Xinmai 69 in Xinyang city of Henan province, the effect of sowing date on the growth and yield components of wheat were studied with 10 sowing times. The results showed that, wheat leaf, tiller number, single stem fresh weight, single stem dry weight, plant height, spike grain number, filling rate, spike length and yield increased firstly and then decreased afterwards as sowing date delayed. The suitable sowing dates of Xinmai 69 in Xinyang were during October 25 th to 30 th.
