Effects of 4 factors,i.e.,method of rearing seedling,sowing rate,fertilization mode and water management,were studied on the super-rice.The results showed that(a)pan-rearing was superior to water-rearing,(b)transplanting in 25 days after sowing gave the best results,(c)75-150kg per hm2 was the best sowing rate,and(d)deep-in-soil fertilization was best for the seedling growth.In addition,over supply of water was detrimental to root development,while maintaining no-water-coverage-over-the-ground promoted root growth,increased root/shoot ratio and improved seedling quality.
