Film hole irrigation under muddy water conditions is a new and effective water-saving irrigation technology. In order to determine the influence of multiple factors on the infiltration process of film hole irrigation under muddy water conditions, 12 sets of indoor infiltration tests were conducted to investigate the effects of four key influencing factors (muddy water sand content, hole diameter, soil bulk density, and infiltration time) on the infiltration characteristics of irrigation with film holes under muddy water conditions, in this study. Based on the experimental data, accurate and effective soil water infiltration and vertical and horizontal wetting front transport models were constructed.

Agricultural drainage significantly affected the changes of soil moisture and salinity in ditch wetlands. These changes can profoundly impact the spatial distribution and evolution of ditch wetland vegetation, thereby affecting the ecological environmental effects of these wetlands. Consequently, it is imperative to investigate the response of typical plant growth to drainage and soil salt in ditch wetlands in arid regions.

Reasonable water and light management technology can improve economic benefits, coffee yield, and quality. We used cluster analysis and principal component analysis to evaluate and optimize the water and light management technology with high coffee yield, quality, and economic benefits in a subtropical monsoon climate region of China. The experiment was arranged in a randomized complete block design with two factors (3 irrigation levels × 4 shade cultivation treatments) replicated four times during 2016-2017.

The purpose of this study was to know the controlling effects of water and nitrogen coupling on the yield, quality, and water-nitrogen utilization effectiveness of mountain apples under surge-root irrigation in the Loess Plateau. In order to optimize the water and nitrogen irrigation systems of superior quality and high yield, 7 years was selected for the mountain apple test material. The trial was designed with four tiers of irrigation, i.

Taking 7-year-old apple trees (Hanfu) as the test material, an experiment with three irrigation levels including high water (W, 85%-100%, was the field water holding capacity), medium water (W, 70%-85%) and low water (W, 55%-70%), and three nitrogen application levels, high (N, 600 kg·hm), medium (N, 400 kg·hm) and low (N, 200 kg·hm), was conducted to investigate the effects of water and nitrogen coupling on photosynthetic characteristics, yield and water and nitrogen utilization of apple trees in mountainous areas under surge-root irrigation (SRI). The results showed that the net photosynthetic rate (), transpiration rate (), stomatal conductance (), intercellular CO concentration (), leaf instantaneous water use efficiency (WUE) of apple trees leaves decreased with decreasing nitrogen application rates under the same irrigation amount, but increased. Under the same nitrogen application rate, foliar , , and WUE decreased with decreasing irrigation amount, but increased.

Water shortage has become a serious problem for the sustainable development of irrigated agriculture in arid regions. In these areas, the scale and planting structure of agriculture suitable for local water resources is particularly important. Irrigation water demand is a crucial indicator of water requirement in irrigation districts.
