Water scarcity and adoption of water-saving irrigation technologies in groundwater over-exploited areas in the North China Plain
Springer Science and Business Media LLC - Tập 39 - Trang 397-408 - 2021
Kunlin Yuan, Zhihai Yang, Shuhong Wang
Water-saving technologies (WSTs) have been publicized for many years in the North China Plain. However, WSTs are not well accepted and farmers have a preference for traditional irrigation technology rather than modern ones. This paper examines determinants of adopting traditional or modern WSTs, especially effects of water scarcity. Using cross-sectional data of 267 farm households, we first categ...... hiện toàn bộ
Plant indicators for scheduling irrigation of young olive trees
Springer Science and Business Media LLC - Tập 21 - Trang 83-90 - 2002
A. Moriana, E. Fereres
The sensitivity of several water status indicators was determined in irrigated young olive trees subjected to two drought periods at Cordoba, Spain. Trunk diameter fluctuations (TDF) were monitored continuously and stem water potential (ψ), leaf photosynthesis (P n) and conductance (g l) were measured periodically on trees where irrigation was inter...... hiện toàn bộ
Benthonic fauna of the Itata river and irrigation canals (Chile)
Springer Science and Business Media LLC - Tập 18 Số 2 - Trang 91-99 - 1998
Habit, E., Bertrán, Carlos, Arévalo, Sergio, Victoriano, Pedro
Benthonic fauna and substrate in three areas of the Itata river (rhithron riffles, rhitron pools, and potamon) and three irrigation canals at the outtake and about 500 m downstream are analyzed. Benthonic fauna included 56 taxa; of these, 12 were exclusive of the river, 11 were only found in irrigation canals, and 33 were in both environments. The widest distributions were found among the Diptera ...... hiện toàn bộ
Irrigation of seed carrots on a sandy loam soil
Springer Science and Business Media LLC - Tập 12 - Trang 193-198 - 1991
J. E. Ayars, R. B. Hutmacher, J. J. Steiner, A. B. Mantel, S. S. Vail
Little research has been reported which quantifies the response of a carrot (Daucus carrota L. var sativa DC.) seed crop to water management. While the area of seed production of this crop in the United States is less than 3000ha, the return ranges from US $2000 to $ 10 000 ha−1. Because of the need to mature and dry the seed on the plant, carrot seed is generally grown in areas with negligible su...... hiện toàn bộ
The effect of different fertigation strategies and furrow surface treatments on plant water and nitrogen use
Springer Science and Business Media LLC - Tập 34 - Trang 53-69 - 2015
Jirka Šimůnek, Keith L. Bristow, Sarah A. Helalia, Altaf A. Siyal
Furrow irrigation and fertigation systems should be designed and managed to optimize the availability of water and fertilizer to plants and minimize their losses through evaporation, deep drainage and leaching. We developed a furrow irrigation submodule for HYDRUS (2D/3D) and used it to evaluate the effects of different furrow soil surface treatments and different timings of fertigation on root wa...... hiện toàn bộ
Mismatch between crop water requirements and irrigation in Heihe River Basin, Northwestern China
Springer Science and Business Media LLC - Tập 37 - Trang 95-103 - 2018
Minghong Tan
Heihe Inland River Basin is the second largest in China. Water use for agriculture in the middle section of the basin accounts for over 90% of total usage; this leads to lake shrinkage, river blanking, and desertification of the downstream basin. Crop water requirements within the Ganzhou district of the Heihe River Basin in Northwestern China were modeled using a parameter calibration of the CROP...... hiện toàn bộ
Dimensional analysis in surface irrigation
Springer Science and Business Media LLC - Tập 15 - Trang 57-82 - 1994
Theodor S. Strelkoff, Albert J. Clemmens
The surface-irrigation design process requires multiple analyses of surface irrigations to test tentative values of design parameters in the search for an optimum. Preparation of general design charts can aid the design process if the users' test cases fall within the scope of the charts. The large number of independent variables in surface irrigation preclude the generation of charts covering the...... hiện toàn bộ
Sustainability of conjunctive water use for salinity control in irrigation areas: theory and application to the Shepparton region, Australia
Springer Science and Business Media LLC - - 1994
J. Bernard Prendergast, C. W. Rose, W. L. Hogarth
Combining remotely sensed surface energy fluxes and GIS analysis of groundwater parameters for irrigation system assessment
Springer Science and Business Media LLC - Tập 32 - Trang 127-140 - 2013
T. K. Alexandridis, A. Panagopoulos, G. Galanis, I. Alexiou, I. Cherif, Y. Chemin, E. Stavrinos, G. Bilas, G. C. Zalidis
Despite being necessary for effective water management, the assessment of an irrigation system requires a large amount of input data for the estimation of related parameters and indicators, which are seldom measured in a regular and reliable manner. In this work, spatially distributed surface energy balance fluxes and geographical information systems analysis of multiple groundwater parameters we...... hiện toàn bộ
