田间结果表明,菊芋在施氮300 kg/hm2、K2O 120 kg/hm2的条件下,施P2O5 60 kg/hm2、120 kg/hm2、180 kg/hm2与不施P2O5相比均有不同程度的增产,其中以施P2O5 120 kg/hm2处理的产量和经济效益最高,在宁夏南部山区种植菊芋最佳施肥方案为:施氮300 kg/hm2、K2O 120 kg/hm2、P2O5 120 kg/hm2.
田間結果錶明,菊芋在施氮300 kg/hm2、K2O 120 kg/hm2的條件下,施P2O5 60 kg/hm2、120 kg/hm2、180 kg/hm2與不施P2O5相比均有不同程度的增產,其中以施P2O5 120 kg/hm2處理的產量和經濟效益最高,在寧夏南部山區種植菊芋最佳施肥方案為:施氮300 kg/hm2、K2O 120 kg/hm2、P2O5 120 kg/hm2.

The field test showed that under the conditions of applying nitrogen 300 kg/hm2 and K2O 120 kg/hm2, the applica-tions of P2O5 at the dosages of 180 kg/hm2, 120 kg/hm2 and 60 kg/hm2 all had effects on the yield of jerusalem artichoke compared with that without P2O5. Among which the yield and economic benefit of the treatment P2O5 120 kg/hm2 were the best. So the optimal fertilization scheme for growing jerusalem artichoke in Southern Mountainous Area of Ningxia is applying nitrogen 300 kg/hm2, K2O 120 kg/hm2 and P2O5 120 kg/hm2.
