Rice seedling raising method

The invention mainly relates to the field of planting technology and discloses a rice seedling raising method. The rice seedling raising method comprises seed selection, seed drying, seed germination, seedling tray preparation, seed plowing, after-planting management and seedling transplantation. The rice seedling raising method is simple, achieves a rice germination percentage up to 98%, shortens the processing time to 4-5 days and improves the economic income by 13.6%; rice seeds are processed through ultrasonic immersion of acetate solution to soften seed coat, to accelerate nutrient content absorption and further to promote germination; absorption of germination accelerator during germination acceleration can be facilitated after seeds are dried, and under appropriate environmental conditions, germination can be accelerated and the germination rate can be improved; nursery substrate is filled into seedling trays after being sterilized to maintain appropriate germination conditions, complex microbial inocu
