摘要: 进行紫色甘薯龙津薯1号种植密度试验,结果表明:每667 m2种植3500株处理地上部与地下部生长较为协调,单株结薯数较多,大中薯比例较高,群体与个体协调性最好,产量最高,每667 m2鲜薯产量3448.5 kg。Abstract: An experiment on planting density of purple sweet potato cv. "Longjinshu No.1" was carried out. The results showed that there was coordinated growth between up-ground and underground part when plant density was 3500 individual plants per 667 m2, showing more tubers per plant, higher ratio of medium-large size tubers, highest coordination relativity between population and individual, highest yield which reached 3448.5 kg fresh tubers per 667 m2.
