Abstract
Few studies of nutrient absorption and utilization were conducted in rape and faba bean intercropping system.A field experiment of rape and faba bean intercropping was carried out to study the effects of the intercropping on crops' yields and N,K absorptions and utilizations under different N application levels.The results show that there is a remarkable intercropping yield advantage in the rape and faba bean intercropping system,and the increased rape yield(15.6%-44.5%) is higher than that(12.1%-26%) of faba bean.In different N levels,land equivalent ration(LER) values range from 1.14 to1.67.The maximum LER value is under the N112.5 level,while the maximum yield is under the N225 level.The N absorptions in lower N levels are increased,and the trend of the amounts of N uptake by rape is in the order: outer raw of intercropping rape inter raw of intercropping rapethe raw of mono-cropping rape.Under both mono and intercropping systems,the amounts of N uptakes by rape are improved under the application of N fertilizer.The maximum N absorption and K absorption of rape seed are under the N225 level.In different N levels,the intercropping could not increase K absorption,however the N transfer from shoots to seeds is improved.
