摘要
采用直播和机插两种栽培模式,研究不同用量有机肥配施化肥氮对早籼稻金早47主要农艺性状及产量的影响。结果表明:直播方式施用250 kg/667m2有机肥产量最高,机插方式施用500 kg/667m2有机肥最为适宜,其产量水平分别达到422.92 kg/667m2和402.08 kg/667m2。
The effects of combined application of different fertilizer rates of organic fertilizer with N fertilizer on main characters and yield of Jinzao47 （early indica rice） under two sawing patterns （direct sowing or machine sowing） were studied. The results showed that when applied organic fertilizer with 3 750 kg/hm2 under direct sowing pattern and applied organic fertilizer with 7 500 kg/hm2 under machine sowing pattern, the Jinzao47 had the highest yield with 6 343.8 kg/hm2 and 6 031.2 kg/hm2, respectively.
