针对承德稻区水稻育秧过程中出现了一系列突出问题，承德市农业技术推广站对该地区育秧技术进行试验探索，集成了“水稻双无育秧法”，结果表明，双无育秧法秧苗期温湿度容易控制，基本保持在20℃左右，适合秧苗生长；基质透气、透水性强，不携带各类病菌，避免了土传病菌的侵害；水稻秧苗根系发达，根须比常规育秧多一倍，根粗、根壮，比常规育苗根长2~3 cm；水稻苗期立枯、青枯、黄化病没有发生，秧苗株型合理、根系发达、带孽率高、插秧后缓苗快；比常规育秧增产3%~4%，效果显著。

Chengde was located in the cold area of northern Hebei planted single-cropping japonica rice. Dryland-raised in small plastic shed and wet-raised adopted in rice seedling raising appeared several problems to have no seedling to plant in the middle and late growth stage of rice seedling: complicated to control temperature and humidity, seedling weak and serious occurrence of rice seedling blight. In order to solve such questions, "double nothing" rice seedling raising method was explored. The results showed that it was easy to control temperature and humidity, rice seedling root was developed and strong, disease in rice seedling period did not occured. With reasonable canopy structure, developed root , high tiller rate and short recovering stage rice yield increased at 3% under"double nothing"rice seedling raising method.
