摘　　要：以Y两优900为材料,在使用和不使用麻育秧膜的情况下,进行了不同播种量田间育插秧试验。结果表明,高播种量处理的秧苗纤细,而秧盘垫铺麻育秧膜处理使得秧苗更壮实;低播种量(55.0 g/盘)导致严重的漏丛,并降低了每丛苗数,从而降低了基本苗数,使用麻育秧膜可以显著降低漏丛率;麻育秧膜处理在较低播种量(55.0 g/盘)条件下仍达到了536.1 kg/667 m^2的产量,高于无膜条件下82.5 g/盘播种量的处理,接近110.0 g/盘播种量的处理。麻育秧膜通过促进秧苗地下部生长发育,调和了秧苗个体素质和群体素质,在相同产量目标下,使用麻育秧膜可以降低播种量。由于杂交稻自身的特性,麻育秧膜尤为适宜用于杂交稻的机插育秧。In order to study the effects of bast fiber seedling film and sowing rate on quality and grain yield of machine-transplanted rice, a field experiment was carried out. The results indicated that the seedling with high sowing rate was slender, while rice seedling raised with bast fiber seedling film was strong. Low sowing rate led serious miss-planting, reduced plant number per hill and the number of basic seedlings, while the application of bast fiber seedling film significantly reduced miss-planting. The treatment of bast fiber seedling fihn reached a grain yield of 536.1 kg/667 m^2 in low sowing rate （55.0 g/tray）, which was higher than that of sowing rate of 82.5 g/tray without bast fiber seedling film, and near to the sowing rate of 110.0 g/tray without bast fiber seedling film. The employment of bast fiber seedling film reconciled the individual quality and group quality of rice seedling by promoting root growth of rice seedling, and had a potential to reduce sowing rate. It would be particularly suitable for machine-transplanted hybrid rice.
