摘要
研究了氮、磷、钾肥的用量对Yacon产量的影响．通过计算机模拟寻优，选出最佳施肥方案为：纯氮202．47～221．09kg／hm^2，磷肥96．6～143．4kg／hm^2，钾肥193．91-286．09kg/hm^2．
The effects of N, P, K on Yacon yield were studied. The simulation computer was used to select the best scheme of fertilizations, which showed that the best levels of N, P, K were 202.47- 221.09 kg/hm^2 ,96.6-143.4 kg/hm^2 and 193.91-286.09 kg/hm^2 respectively.
