摘要
采用 2因素随机区组设计 ,对华安 3号密度和施氮量的主效和互作效应进行了研究 ,结果表明 :密度、施氮量和密度×施氮量对产量的影响均达显著水平。密度 18.0万穴 /hm2 、大田纯氮 187.5kg/hm2 是最理想的处理 ,结合宽行窄株栽植法 ,可以实现高产高效栽培 。
The experiment in main effect of rice combination Huaan No.3 planting density and the application of N-fertilizer and their interaction was carried out by the randomized block design. The result indicated that the yield was significantly affected by the planting density, the application of N-fertilizer and their interaction. The best treatment was plant density: 180 thousand holes/hm 2 , the application amount of N-fertilizer: 187.5 kg/hm 2 , combining with the special cultured techniques for high yield.
