1979年以来,随着单季晚粳种植面积的恢复和发展,原来成本昂贵的工厂盘秧、工序多花工量大的稀播大秧(常规秧)和小苗条寄秧已逐步改变为成本低廉、工序简化用工少的露地小苗直栽秧。由于露地小苗直栽秧是旱播、密播、早栽,因此移栽一亩大田比常规秧可少用0.11亩秧田,用来秋播可增收小麦25公斤,少做秧田又能省工、省本,当季水稻还能增产。露地小苗保持了工厂秧播种密度高、占用秧田少、秧龄短、利于创造秧苗生长的温、湿、肥等条件和出苗整齐、成苗率高等优点,并弥补了工厂秧需要设备 Since 1979, with the recovery and development of the planting area of ​​late-season japonica rice in single season, the costly plant seedling cultivation, the large number of large planting seedlings (conventional seedlings) and the seedlings growing in the process have gradually been changed to the cost Low cost, streamlined work Less open field seedlings planted directly. As the open seedlings planted directly to the open air is dry, densely sowed, early planting, transplanting a mu of field than the conventional seedling can be used less 0.11 acres of seedling, used to increase the yield of wheat in autumn 25 kg, Provincial capital, seasonal rice can increase production. Open seedlings to maintain plant seedling planting density, occupy less seedling, seedling age is short, conducive to create seedling growth temperature, humidity, fertilizer and other conditions and emergence of neat, high rate of seedlings, and make up the plant seedlings need equipment
