通气育秧做法简易,有利于秧苗生长,秧苗素质好,成秧率、分蘖率都比半水育秧的高。如我县公安公社大田大队第11生产队,1978年早稻同是3月15日播的一批种,于3月20日开始遭到强寒潮的袭击,平均气温为9℃的天气持续了6天,4月11日调查烂秧情况,通气秧的成秧率比半水秧的高15.2—20.9％。插秧前调查秧苗分蘖数,通
Ventilation nursery practices simple, conducive to seedling growth, good quality seedlings, into seedling rate, tillering rate than semi-watering seedlings high. For example, the 11th production team of the Daejeon Brigade of the County Public Security Commune was the same as the one broadcast on March 15 in 1978. The attack started with a strong cold wave on March 20, and the weather with an average temperature of 9 ° C lasted 6 Day, April 11 investigation of rotten seedling situation, the ventilation seedling seedling rate 15.2-20.9% higher than semi-water seedlings. Transplanting seedlings before tillering investigation, pass
