摘要
经研究和示范证实，选择物理量适当的参数，超声可促进水稻发芽、分蘖、成穗和提高产量。本文论述超声影响水稻生长发育及产量是超声的空化效应。空化效应对水稻种子中的生物活性物质有影响。
As the research and experiment have proved,if a proper physical parameter is chosen,the ultrasonic can promote or accelerate the growth of rice in its germinating,tillering,and ear growing,and can also increase the production of rice.The paper discusses that the ultrasonic.That affects the growth and prodution of rice,is a cavitation effect of the ultrasonic,and that the cavitation effect certainly has some effect upon the bio-active material inside the rice seed.
