| 摘 要： | 小麦二叶期喷施旱地龙(FA)、三十烷醇(TRIA)、尿素+磷酸二氢钾等化学物质能促进小麦根系伸长,加大根冠比. 旱地龙可有效地缩小叶面气孔开度.旱地龙和三十烷醇可提高叶绿素含量.在小麦孕穗期和灌浆期喷施这3种化学物质可显著地提高产量,以三十烷醇效果最好,其产量比对照增加2 040.9 kg/hm2.

| Abstract: | Chemical matter Fulvic Acide(FA),Triacontanol (TRIA) and Urea + Potassium Dihydrogen Phosphate (CO(NH 2)2+KH 2PO 4) sprayed on wheat in two-leaf period promoted the growth of root system and the ration of root to shoot. FA could decrease the opening degree of wheat stoma. FA and TRIA could increase the content of chlorophyll. Three chemical matters sprayed in the stage of spike formation and grain filling could significantly increase wheat production. By spraying TRIA, the grain yield was increased 2 040.9 kg/hm 2 compared with CK. |
