摘　　要：以旱稻277为材料,在1叶1心期进行了不同浓度多效唑喷施试验。麦茬旱稻苗期喷洒多效唑对植株高度有明显的降低作用,可提高秧苗素质和抗倒力。同对照相比,叶面喷施多效唑可使麦茬旱稻产量增加10%左右。增产的生理作用主要表现在光合速率提高,气孔导度和蒸腾速率提高。叶面喷施多效唑可增加麦茬旱稻的穗粒数。The foliar application of MET solution significantly decreased the height of upland rice plants,while the seedlings quality and resistance to lodging were increased.The grain yield of plants increased by 10% than that of the control due to the increased panicles and spikelets per panicles.The physiologic function of the yield increasement was chiefly due to the improved chlorophyll content,photosynthetic rate and the stomatal conducence of leaves after treated with MET.
