摘　　要：利用人工气候室在苗期施用水稻壮秧分蘖剂对水稻秧苗的形态及生理方面的表现进行了探讨。结果表明 :水稻壮秧分蘖剂具有增加秧苗干物重 ,提高秧苗素质 ,降低电解质渗出率和提高脯氨酸含量的作用。In phytotron,the effect of rice seedlings and tillering promoting agent on morphological and physiological properties of rice seedlings in seedtime were investigated.The results show that the rice seedlings and tillering promoting agent can improve dry matter weigth and quality,decrease permeability of dielectric and increase content of proline. At same time the tillering ability of seedlings and the yield of rice are raised.
