研究棉花花芽分化剂艾氟迪(AFD)对棉花农艺性状及产量的影响。结果显示:随着AFD施用次数增加,在花铃期保花保蕾效果不明显,在吐絮期棉花的花、蕾、脱落数和果枝数明显减少,株高、铃和吐絮数则增加,子棉产量也有所提高。这表明AFD药效发挥较慢,应在棉花生育期的早期施用。
The effect of cotton flower bud differentiation agent, aludin (AFD) on agronomic traits and yield of cotton was studied. The results showed that with the increase of the number of AFD application, the effect of protecting flower buds was not obvious during the flower-boll stage. The number of flowers, buds, shedding and fruiting branches in cotton boll opening stage decreased significantly while the number of bolls and bolls increased Cotton production has also increased. This indicates that the efficacy of AFD is slower and should be applied early in the growing season of cotton.
