水稻抛秧是一项国家重点推广的新型水稻高产高效栽培技术,具有省工、省力、高产、高效的显著特点。1997年承德市推广面积2067hm~2,平均667m~2产658.4kg,比常规插秧稻平均667m~2节约生产成本85.90元,667m~2增产32.6kg,纯增收益140.67元,收益1077.01元,但这项技术在实际应用中必须把好“四关”,才能保证高产、高效,获得较好的经济效益。 一是育苗关。抛秧育苗采取塑料软盘旱育苗技
Rice seedling throwing is a key new high-yield and high-efficient cultivation technique promoted by the state, which has the obvious features of saving labor, saving labor, high yield and high efficiency. In 1997, Chengde City had an area of 2067 hm ~ 2 with an average of 667 m ~ 2 and an output of 658.4 kg. The average production cost was 85.90 yuan and 667 m ~ 2 respectively, an increase of 32.6 kg compared with conventional rice transplanting. The net gain was 140.67 yuan and the profit was 1077.01 yuan. In the practical application of this technology, it is necessary to have a good “four-off” to ensure high output, high efficiency and good economic benefits. First, nursery clearance.
