| 摘 要： | 试验结果表明,平均1 kg N素增产鲜芋6.77 kg,平均1 kg K2O增产鲜芋8.0 kg。磷钾配合优于氮磷配合,氮磷钾配合最好。1 hm2施N量216 kg、施K2O 280 kg时,鲜芋产量最高。氮钾配合与磷钾配合都能提高魔芋生产的经济效益,但差于氮磷钾配合。1 hm2配合施用N 122 kg、P2O572 kg、K2O 147 kg的经济效益最佳。种植魔芋后各处理的土壤养分状况发生了重大变化,土壤有机质、碱解氮各处理均降低,施用钾肥较多的处理速效磷和速效钾增加。 |

| Abstract: | The results of experiment showed that nitrogen per kilogram increased production of 6.77 kg konjac corms,and K_2O per kilogram increased 8.0 kg.The assortative applying with P,K was superior to that with N,P,and that with N,P,K was the best.When fertilizing N 14.44 kg,K_2O 18.72 kg per 666.7m~2,the yield of konjac was the highest.The assortative applying with N,K and that with P,K all promoted the economic benefits of konjac production,but the effect was less than that of the assortative applying with N,P,K.As the fertilization was N 8.14 kg,P_2O_5 4.80 kg,K_2O 9.80 kg per 667m~2,the economic benefit was the highest.The soil nutrient conditions of each treatment varied largely after planting;both the soil organic matter and alkali nitrogen of each treatment decreased.The contents of available P,K increased in the treatments fertilized more K. |
