如东5号大麦播量6．5～9．0kg／亩，一生总用氮基肥占50％～60％、苗肥占20％、拔节孕穗肥占20％～30％，可获得400kg／亩以上的产量水平。播量降至4kg／亩时，有效穗明显不足，难以获得高产。随着播量增加，一生总出叶数减少，有效穗增加。
Rudong 5 barley sowing 6.5 ~ 9.0kg / mu, total nitrogen fertilizer for life accounted for 50% to 60%, 20% Miao Fei, jointing booting 20% to 30%, available 400kg / mu Above the level of output. Sowing down to 4kg / acre, the effective panicles significantly insufficient to obtain high yield. With the increase of sowing, the total number of leaves in a lifetime decreased and the effective spike increased.
