摘  要:
在豫东潮土研究施肥对甘薯产量、生产情况的影响,分析不同施肥处理的产量及经济效益。结果表明,甘薯应不施或少施N肥,补施P、K肥;单施P、K肥分别比对照增产2.23%和1.16%,单施N肥比对照减产0.02%;N、P、K配合施用最佳配方是N_5P_9K_(10),其效益最高,为44 251.0元/hm~2,比对照增收355.3元/hm~2,鲜产量为30 713.9 kg/hm~2,比对照增产4.96%,分别比单施N、P、K增产4.98%、2.67%和3.75%。

摘  要:
The effects of fertilizer on growth,yield of sweet potato are studied,the yield and economic benefitof difficult fertilizer treatment are analyzed. The results show: for sweet potato,the dosage of nitrogen fertilizershould be controlled, the proportion of phosphorus and kalium fertilizer should be increased properly;the yieldincrease rates of applying N, P, K to contrast are respectively- 0.02%,2.23%,1.16%;the best N, P, Kapplication proportion is N_5P_9K_(10), which has the highest benefit of 44 251.0 RMB Yuan/hm~2, benefit is increasedby 355.3 RMB Yuan/hm~2,the fresh yield is 30 713.9 kg/hm~2 with the increase by 4.98%,2.67%,3.75% to Ntreatment, P treatment, K treatment,contrast treatment respectively.
