目前大部分水稻产区在早稻催芽时采用人工催芽,出芽率一般只有70—80%,根芽整齐度差,有时会发生烧芽和闷芽现象,既浪费了稻种,又耽误了农时。湖州市农机研究所参考了日本稻种催芽器,研制成功CY—81型恒温稻种催芽器,并进行了早稻育秧 At present, most rice producing areas use artificial germination during germination of early rice. The germination rate is generally only 70-80%, and the uniformity of root and sprouts is poor. Sometimes, the phenomenon of burning and stuffy buds occurs, which is not only a waste of rice seeds but also a delay of farming time. Huzhou City, Agricultural Machinery Research Institute reference to the Japanese rice germiculator, the successful development of CY-81-type thermostat rice seed germination, and early rice seedlings
