摘要
采用裂区试验设计,对高产优质杂交稻N优2号进行密肥试验。分析结果表明:在中等肥力的稻田条件下,N优2号适宜的栽植密度为16.5 cm×28.4 cm,适宜的氮肥施用量为6 kg/667 m2;其再生能力强,适宜留桩高度为40 cm。
Different combinations of planting density and fertilizer rate were used in a field experiment to select the optimal combination for realizing high yield and good quality of a new mid - season rice variety N You 2. The results showed that the optimum planting density and N rate were 16.5 × 28.4 cm and 6 kg/667 m^2 , respectively. This variety proved to have great ratooning capacity and the optimum stubble height for it was 40 cm.
