摘要
进行甘薯不同氮肥施用量试验,结果表明:每667 m2施N 9~12 kg能较好的协调甘薯地上部与地下部的生长,甘薯经济性状较优,鲜薯产量最高。
An experiments on applying different rates of nitrogen fertilizer to sweet potato was carried out. The results showed that the fertilizer-applying amounts of N was 9 - 12 kg/667 m2 ( 135 - 180 kg/hm2 ) could better coordinate the growth both of up-ground part and underground part of sweet potato plants, and get better economic characters, thus their fresh tuber yields were the highest.
