摘　　要：通过劳模示范田栽培调查，分析了偏高秆、偏大穗粳爪交组合优８１４２的栽培特性，并总结以大垅双行稀植为中心的高产配套技术。Through two years of demonstrative cultivation by model farmers,the high-yielding cultur-al characteristics of the early japonica hybrid rice Sasanishiki A/C8142 were analyzed and summarized as fol-lows:(1)strong tillering ability to approach easily 3.3～3.6 million panicles/hm￣2;(2)high blomass due tolargcand durable functional leaves;(3)odging resistance for a short basal internode;(4)medium fertilizertolerance with an appropriate amount of pure nitrogen less than 173.3 kg/hm2 Based on the characteristics,the main cultural practices are recommended as :(1)adopting aternated wide rows with narrow rows;(2)raising vigorous seedlings by sparse sowing;(3)applying N in the early growth stage to improve tilleringfor enough tillers,controlling culm elongation in the middle stage for stiff straw,applying P and K fertiliz-ers in the late stage for earlier maturity.
