1990年我省水稻栽培面积已突破1100万亩,居东北三省之首。水稻旱育稀植技术在我省推广以来,由于秧苗素质好,抗逆性强,能充分发挥水稻分蘖特性,对寒地稻作生态环境有较强的适应性等特点,栽培面积不断扩大,到1988年旱育稀植栽培面积已达700多万亩,成为我省水稻主要种植方式。但是,由于旱育苗需调酸、消毒、施肥等,作业程序繁杂和用工量大,在生产上常因操作不当,技
In 1990, the rice cultivation area in our province exceeded 11 million mu, ranking the first among the three northeastern provinces. Since the popularization of rice germplasm cultivation technology in our province, due to the good quality of seedlings, strong resistance, can give full play to the tillering characteristics of rice in the cold paddy ecological environment has strong adaptability and other characteristics of the growing area continues to expand, By 1988, the area of dry cultivation and sparse planting reached more than 700 million mu, becoming the main planting mode of rice in our province. However, due to drought nursery need to adjust the acid, disinfection, fertilization, operating procedures complicated and laborious, often due to improper operation in the production, technology
