Résumé partiel
Ridge and furrow rainwater harvesting planting system is gradually implemented in semi-arid areas because it can effectively improve the soil water temperature environment,promote crop growth,and have the effect of stabilizing production and increasing production.It has great practical significance to improve the light energy utilization rate of winter wheat and improve the ridge and furrow rainwater harvesting planting technology through reasonable fertilization.The study set four fertilization gradients(N0P0,N 0 kg hm-2:P2O5 0 kg hm-2 ;N90P60,N 90 kg hm-2:P2O560 kg hm-2 ;N180P120,N 180 kg hm-2:P2O5120 kg hm-2 ;N270P180,N 270 kg hm-2:P2O5 180 kg hm-2)under the rainwater harvesting planting mode(conventional flat as the control)in a typical semi-arid area(Pengyang County,Ningxia)from 2017 to 2019.We analyzed the effects of fertilization amount on the photosynthetic physiological characteristics of winter wheat leaves,light energy utilization of canopy,yield composition,fertilizer utilization and economic benefits.
