摘要
研究了中粳稻“9404”适宜栽培密度和施肥技术,结果表明:该品种的适宜栽插密度为:45万穴/ha,2-3本基本苗/穴。KCl:基肥和返青肥各75kg/ha;尿素:基肥150kg/ha,返青肥150kg/ha,促花肥、保花肥及齐穗肥各75kg/ha。产量可达8081.25kg/ha。
The optimum planting density and fertilization techniques of semilate Japonica rice “9404” were studied . The optimum combination of cultivation measures was as follows:0.45 million hills/ha. 2-3 seedlings /hill;75kg/ha kcl as base fertilizer and as top dressing in return green stage, respectively ; 150kg/ha urea as base fertilizer and 150kg/ha urea in return green stage,75kg/ha each in tillering stage. heading stage and flower stage, rspectively. The high yield over 8081.25kg/ha was obtained by the combination of the cultivation measures.
