Development of a new rotational irrigation model in an arid basin based on ecological zoning and sluice regulation Agric. Water Manag. (IF 6.7) Pub Date : 2024-04-02 Mengyi Li, Mingjiang Deng, Hongbo Ling, Jia Xu
Precise and efficient allocation of existing water resources is of great significance to protect and restore desert riparian forests in inland river basins. However, the lack of detailed ecological zoning in most basins hinders the optimization of the current ecological sluice regulation scheme, leading to low effectiveness in vegetation restoration and water resources management. To address this problem

The impact of global cropland irrigation on soil carbon dynamics Agric. Water Manag. (IF 6.7) Pub Date : 2024-04-01 Xiaochen Yao, Zhiyu Zhang, Fenghui Yuan, Changchun Song
Irrigation can increase crop yields and could be a key climate adaptation strategy. At present, under the background of increasing food demand and continuous expansion of irrigation cropland, there still uncertainties about the soil carbon dynamics under the change of irrigation water volume and irrigated area in view of large-scale spatial heterogeneity. Therefore, this paper uses space-for-time +

Optimizing bent branch numbers improves transpiration and crop water productivity of cut rose (Rosa hybrida) in greenhouse Agric. Water Manag. (IF 6.7) Pub Date : 2024-03-30 Xuanpeng Yin, Junji Chen, Yunyu Ye, Hongfeng Zhu, Junyu Li, Lizhen Zhang, Hao Zhang, Shuilian He, Hongzhi Wu
Bent branches are commonly utilized in cut roses to enhance commercial flower quality through increased nutrient production and biomass. However, the ideal number of bent branches concerning crop water productivity remains unknown. The experiment was conducted in Jinning, Yunnan, in 2022 with total of three growth periods with 1–3 bent branches. Sap flow of a commercial branch was measured using the

Evaluation of N nutrition and optimal fertilizer rate for ridge-furrow mulched maize based on critical N dilution curve under different water conditions Agric. Water Manag. (IF 6.7) Pub Date : 2024-03-29 Pengzhao Liu, Zhen Fan, Zinan Yan, Xiaolong Ren, Xining Zhao, Jianjun Zhang, Xiaoli Chen
Optimizing nitrogen (N) management based on the critical N dilution curve (N) has been proven a precision fertilization strategy to diagnose crop N nutrition status. However, few explorations have been done to establish a N for dryland maize under double ridge-furrow mulching, a planting system that has been widely adopted in semi-arid areas. Moreover, the influences of various rainfall conditions
