摘　　要：为了筛选培育适龄壮实大钵体毯状苗的最佳育秧基质与营养土配比,研究了5种育秧基质与营养土配比处理对水稻秧苗素质、分蘖动态、叶面积指数和产量等的影响。结果表明,A_(1)B_(2)处理(66.7%育秧基质+33.3%营养土)培育的大钵体毯状苗的出苗率、地上部形态、地下部形态、根系盘结力最好,秧苗素质优于其他处理;A_(1)B_(2)处理的水稻分蘖强度、叶面积指数均大于其他处理,且产量最高。因此A_(1)B_(2)处理的育秧基质与营养土配比(66.7∶33.3)是最佳的。In order to explore the optimal ratio for cultivating suitable-age and sturdy large-bowl blanket seedlings,the effects of 5 different ratios of seedling substrate and nutrient soil on seedling quality,tillering dynamic,leaf area index and yield components were studied.The results showed that the A_(1)B_(2)treatment(66.7%seedling substrate+33.3%nutrient soil)had the best seedling emergence rate,aboveground morphology,underground morphology and root binding ability.The seedling quality was better than those of other treatments.At the same time,the tillering intensity and leaf area index were higher than those of other treatments,and the yield was the highest,indicating that A_(1)B_(2)treatment(66.7∶33.3)was the best ratio of seedling substrate and nutrient soil.
