与插秧相比，塑盘抛秧各生育期根量大、活力强、分布表层较多，前期优势更明显；分蘖早、苗数增长快，有效分蘖节位低、成穗蘖多；叶面积发展快，封行期和苗峰期提早；秧苗期地上部个体生长慢，但本田期生长加快，弥补其生长不足，群体生长量具有优势；中期植株全氮含量下降明显。 Compared with transplanted riceplanting seedling throwing growth period of the large amount of root, strong vitality, distribution of surface more pre-advantage is more obvious; early tillering, seedling number increased rapidly, effective tillering node is low, spike tiller; leaf area The growth of the seedlings was earlier, the duration of the seal and the early stage of the seedling peak were earlier. The individuals in the upper part grew slowly in the seedling stage, but the growth in the field was accelerated to make up for the lack of growth and the population growth had the advantage.
