水稻的一生可以分为幼苗期、分蘖期、拔节孕穗期,抽穗开花期和灌浆成熟期五个生育时期。 11) 幼苗期:从秧田播种到分蘖开始称为幼苗期。稻种发芽的最低温度在10℃,以上到15℃时才比较迅速,最适宜的温度是25~30℃。幼苗期通常采用浅水灌溉或湿润秧田,以利培育壮秧。 Rice’s life can be divided into seedling stage, tillering stage, jointing booting stage, heading and flowering and filling maturity of five growth stages. 11) Seedling: Sowing from seedling to tillering is called seedling stage. The minimum temperature of rice germination at 10 ℃, more than 15 ℃ only when more rapid, the most suitable temperature is 25 ~ 30 ℃. Seedlings usually use shallow water irrigation or wet seedling, to facilitate the cultivation of strong seedlings.
