摘要: 为探求适宜水稻(Oryza sativa L.)生产抗旱减损的抗旱剂,选取了FA旱地龙、旱立停、脱落酸3种抗旱剂进行大田试验。结果表明,在发生干旱时,3种抗旱剂均能增加水稻叶片叶绿素含量和穗长;FA旱地龙可提高结实率,旱立停可增加每穗实粒数,旱立停和FA旱地龙的增产幅度均达显著水平(P<0.05),在水稻生产中合理应用这2种抗旱剂能够有效减轻旱灾损失。

Abstract: In order to find suitable drought-resistant agents for rice(Oryza sativa L.) production, field experiments were conducted using three candidate drought-resistant agents, namely, FA Handilong, Hanliting, and abscisic acid. The results showed that in the case of drought, all the three drought resistant agents could increase the chlorophyll content of leaves and panicle length of rice. In addition, FA Handilong could increase the seed setting rate, and Hanliting could increase the number of grains per panicle. Both Hanliting and FA Handilong could significantly increase the grain yield(P<0.05). Rational application of these two drought-resistant agents in rice production may effectively relieve drought losses.

Key words: rice(Oryza sativa L.), drought, drought-resistant agents, grain yield
