应用超声物理因素刺激农作物发芽增产的研究,在三十年代即已开始。五十年代以后,随着物理学和生物学的发展,这一研究工作逐渐广泛开展。国内外报导过一些试验报告,但多属零星片断和偏重于旱期,尚处于实验室阶段。较大规模的试验还是近十余年的事。我们所于一九六二年开始了超声照射处理冬小麦种子的实验研究。十余年来,在各级党委的支持和领导下,在西安市小寨公社沙乎坨试验站,山门口公社试验站等单位的协助 The application of ultrasonic physical factors to stimulate crop germination and production increased in the thirties. After the 1950s, with the development of physics and biology, this research work has been gradually carried out. Some reports have been reported at home and abroad, but mostly sporadic fragments and emphasis on the dry period, is still in the laboratory stage. Larger test is still a matter of more than ten years. In 1962, we started an experimental study on the treatment of winter wheat with ultrasonic irradiation. For more than ten years, with the support and leadership of party committees at all levels, they have been assisted by units such as Shahu Tuo Experimental Station of Xiaozhai Commune in Xi’an and Shanmenkou Commune Experimental Station
