| 摘 要： | 为给大穗型小麦品种兰考矮早八的种植选择适宜的行距,在大田高产栽培条件下,设置10、15、20、25 cm 4个行距处理,研究了行距对其花后旗叶光合物质生产及籽粒产量的影响.结果表明,行距对小麦旗叶叶绿素含量和光合速率均有明显影响,均表现为15 cm>10 cm>20 cm>25 cm.窄行距处理的旗叶可溶性糖含量在花后0～28 d较低,而在花后35 d较高.窄行距也有助于提高旗叶蔗糖含量,其中以15 cm行距最高.与其他处理相比,15 cm行距能显著增加单位面积穗数,协调产量构成因素,显著提高产量.

| Abstract: | Field plot experiments were carried out to examine the effects of row spacing on photosynthetic production of flag leaves and grain yield in heavy-ear wheat Lankao Aizao8 on the farm of Henan Agricultural University during 2006-2007.The results showed that chlorophyll content,photosynthesis rate,soluble sugar content and sucrose content in flag leaves increased in earlier filling stage with irrigation times increasing,and decreased in later filling stage.The effects of row spacing on chlorophyll content and... |
