摘  要：
应用高吸水种衣剂对水稻种子进行包衣处理，不浸种不催芽直接播入旱育苗床，考查了它对种子的出苗、病虫害及死苗的防治、秧苗素质以及抛栽后立苗速度、抗植伤能力和产量形成的影响。高吸水种衣剂包衣处理在种子周围及秧苗根部形成了18cm×1．5cm×1．2cm左右的“蓄水球囊”，不仅提高了种子出苗率、成秧率，有效地防止了多种病虫害及死苗的发生，壮大根群，提高了秧苗素质；而且实现了旱育秧苗根部带土抛植，提高了立亩速度和抗植伤能力，增加了旱育抛栽稻的产量。

摘  要：
Rice seeds were coated with high-hydroscopicity seed coating material and sowed in dry-raisingseedling bed without seed-soaking and pregermination. The treatment of high-hydroscopicity resin seed-coatingmaterial can fornl a water-stored ball of about 1. 8 cm × 1. 5 cm × 1. 2 cm around seed and root, the ball has the abilities of absorbing, keeping and providing water. As the ball containing pesticide, germicide and plant regulatorand releasing slowly, it may afford a suitable surroundings for germination and seedling growth. The procedure cannot only enhance emergence and seedling rate, prevent diseases , pests and died seedlings, strengthen root system,improve seedling qualities, but also can scatter dry-raised seedlings with more soil, improve seedling-standingspeed and resist to planting injury, increase the yield of dry-raised scattered-transplantation rice.
