水稻旱育秧由日本专家原正市等开发，首先推广于日本北海道，后引入我国。1993年，在安徽省宣州市丁店乡进行水稻旱秧试验，至1997年，旱育秧田达万亩以上。由于水稻旱育秧具有秧亩素质好、早熟、抗病性强等优点，其产量比水育秧平均每亩可增产～伦g。现总结如下。l早熟，扩大 Upland rice cultivation by Japanese experts Harajuku and other developed, first promoted in Japan Hokkaido, after the introduction of our country. In 1993, Dian Dian Township, Xuanzhou City, Anhui Province, carried out experiments on paddy rice cultivation. By 1997, the number of dry seedlings reached more than 10,000 mu. As a result of rice dry nursery seedlings have good quality seedlings, early maturity, disease resistance and other advantages, the output of seedlings per hectare than the average water yield can increase ~ Lun g. Now summarized as follows. l precocious, expanded
