摘要
采用二因素随机区组设计 ,通过盆栽试验 ,从生理指标和产量指标研究 3种植物生长调节剂在两种不同浓度下对冬小麦后期生长发育的影响。结果表明 ,在低浓度下 ,喷施农家宝的小麦旗叶光合强度最强 ,喷施旱地龙的小麦抗旱能力最强 ,喷施农家宝、旱地龙、PP2 0 0 3的小麦产量比对照都有所增加。在高浓度下 ,喷施PP2 0 0 3的小麦抗旱能力最强。喷施高浓度的 3种植物生长调节剂后 。
In present two-factor randomized block designed pot incubation, effect of 3 growth regulators in two different concentrations on wheat development at later stage were studied. The results showed that at a low concentration flag-leaf applied with Nong-jia-bao(njb) has the highest intensity of photosynthesis, wheat applied with Han-di-long(hdl) has the highest drought-resistance and wheat applied with njb, hdl and PP2003 has a higher yield than that of the control; As far as the effect at a high concentration is concerned, drought-resistance of wheat applied with PP2003 is the highest, while wheat applied all three above mentioned growth regulators at high concentration has a relative yield failure than that of the control.
