[目的]为提高机插钵苗专用秧盘利用率,降低育秧成本.[方法]用同一批秧盘在同一育秧季节先后育再生稻秧苗、一季中稻和麦茬稻秧苗,研究并比较其秧苗素质、产量及产量构成.[结果]同一批秧盘先后育出的3批秧的秧苗素质好、分蘖正常、产量高.且“一盘三用”将秧盘投入成本从787.5元/hm2降到262.5元/hm2,比正常机插毯苗育秧成本还低.[结论]机插钵苗“一盘三用”在信阳地区是可行的,能达到节本增效的目的,并且播期提早能够提高产量.%[Objective] To increase the utilization rate of pot seedling tray and to reduce the cost of seedling raising.[Method] The same batch of trays were used to cultivate ratoon rice,single-season Indica rice and rice after wheat in the same seedling cultivation season.Seedling quality,yield and its composition were researched and compared.[Result] The three batch of seedlings had good seedling quality,high yield,and normal tillering.Cost of using one tray for three times decreased from 787.5 yuan/hm2 to 262.5 yuan/hm2,which was even lower than carpet seedlings.[Conclusion] Using one special tray for three times for rice pot seedling in Xinyang region was feasible,could save cost and improve efficiency.And early sowing date could enhance the yield.
