近年来,日本为了适应机械化插秧的需要,推广一种箱育小苗的育秧方法,将育秧过程分为三个阶段,即催芽期、绿化期和硬化期。整个过程在能调节温度的室内进行。机插小苗虽有带土、带胚乳养分、根系机能保持好和成活迅速等特点,但是,苗期管理不善,生长过茂,秧苗细弱不壮,也会延迟成活,
In recent years, Japan in order to meet the needs of mechanized planting, popularize a method of seedling seedlings nursery, the seedling process is divided into three stages, namely germination, greening and hardening period. The whole process can be carried out in the room temperature can be adjusted. Although the machine inserted seedlings with soil, with endosperm nutrients, root system to maintain good and rapid survival characteristics, however, poor management at seedling stage, overgrown Mao, seedling weak and weak, will delay the survival,
