摘　　要：为了进一步挖掘泸优明占作再生稻的生产潜力,对其不同留桩高度、在低桩栽培下的促芽肥施用时间对再生季产量影响等进行了研究。结果表明:留桩高度为20 cm的再生稻产量最高,每667m^2为250.0 kg;割后6 d施用促芽肥的再生稻产量最高,每667m^2为323.5 kg。Effects of stubble height and fertilizer application time for bud development with low stubble on ratoon rice yield were surveyed to explore the productive potential of Luyoumingzhan.Results showed that 20cm stubble height obtained highest ratoon grain yield 250.0 kg per 667m2 and fertilizer application 6 days after main-crop harvest had the highest production 323.5 kg per 667m2.
