水稻通风炼苗,就是根据秧苗生理需要,为其创造一个较为有利的生长条件,使之适应外界环境,增强抗性,为全部揭膜做准备,培育出健壮秧苗.有人认为,在水稻秧苗通风炼苗期间,床内温度最好保持25℃左右.这个温度指标没错,但很难实现.即使育秧人整天不离开苗田,也不能不出偏差.近两年,我采用了“两早”通风炼苗法,培育的秧苗健康、无病,我认为是一种比较好的炼苗法.所谓“两早”就是每天通风要早,午后盖膜也适当提早.具体做法是,从秧苗1.5叶期开始通风炼苗,每天当气温达11—12℃时就
Rice ventilation Hardening, is based on physiological needs of seedlings, to create a more favorable conditions for its growth, to adapt to the external environment and enhance resistance, in order to expose all the film in preparation to cultivate robust seedlings. Some people think that in the rice seedlings ventilation During the tempering period, the best temperature in the bed to maintain about 25 ° C. This temperature indicator is true, but difficult to achieve. Even if the nursery seedlings do not leave the field all day, it can not be deviated .In the past two years, I used the “two early ”Ventilation Lianniao law, nurturing the seedlings healthy, disease-free, I think it is a better method of refining the so-called“ two mornings ”is the daily ventilation to early, the afternoon cover film is also appropriate early .That is, from the seedling 1.5 leaf stage ventilation Hardening, daily when the temperature reaches 11-12 ℃ on it
