| 摘 要： | 利用3种不同浓度的抗旱剂(FA旱地龙),在山西省万荣县冬小麦生育的关键期分3次和2次,进行了叶面喷施抗旱试验研究.结果表明:在冬小麦拔节期、孕穗期和灌浆期对叶面喷施一定浓度的抗旱剂,都有明显的抗旱增产效果;在干旱年份,喷施高浓度的抗旱剂比喷施低浓度的抗旱剂增产效果要好,喷施3次比喷施2次的抗旱增产效果好,6种处理的理论产量增产百分率在8.2%～38%之间.喷施抗旱剂主要是提高了冬小麦的抗逆性,提高了土壤水分的利用效率,对提高成穗率、穗粒数和千粒重有利. |

| Abstract: | The pilot study on rought-resistant foliage spraying is made with the treatments of using three different concentrations of a drought-resistant FA(Dryland Long) spraying on winter wheat foliage at the critical growth period of winter wheat in three times and two times of six kinds,in Wanrong County,Shanxi Province. The results showed that: spraying a certain concentration of the drought-resistant FA on winter wheat foliage in jointing,booting and filling stage,the drought-resistant effect has significantly ... |
