水稻空气整根营养钵秧苗移栽后生长发育特性及产量的研究

采用空气整根营养钵育苗方法研究了身苗移栽后的生长发育特征及产量表现。结果表明：用该方法培育的秧苗移栽后不缓苗，植株生长健壮，叶面积指数大，干物质积累量大，分蘖发生早，分薛数多，根系发达，根体积大，根系数量多，活力高。群体穗数增加，每穗粒数和千粒重有所提高，产量比普通秧苗增加5.75%。

Study on the Growth Characteristics and Yield Manifestations of Air-Pruning Pot Rice Seedlings after Transplanting

Rice seedlings were grown in air-pruning pots and their growth characters and yield manifestations after transplanting were studied. The results show that instead of needing a period of revival, such seedlings develop strong growth with larger leaf area index and dry matter accumulation. Seedling tiller takes place early and in a large amount. Roots are of great growth power, large quantity, large volume and high vitality. Number of panicles increases for population. Number of grain in each spike increases. So does thousand-grain weight. Yield can increase by 5.75 percent.
