“…When applying drip irrigation systems to wheat production, the required horizontal distance of water supply for one drip tube is related to the number of wheat rows and wheat row spacing [9,12]. Appropriately narrowing wheat row spacing could reduce the water supply distance of drip tube, shorten irrigation cycle, and effectively reduce the difference in water and fertilizer between wheat rows [11,29]. In addition, some studies suggest that planting wheat in wide-narrow rows could improve the growth space of plant, increase ventilation and light transmission of plant populations, and fully utilize the marginal advantage, which was beneficial for improving yield [23,55,56].…”

“…Drip irrigation technology has been rapidly promoted in wheat production in Xinjiang since 2008 because of its advantages of water saving, yield increasing, and labor saving [7,8]. However, due to the whole drip irrigation system is transplanted from cotton [9,10], the relevant theoretical basis is weak, and its mechanism research is not mature enough [11,12], which makes it difficult to achieve the goal of efficient resource utilization and sustainable income increasing when drip irrigation system were used to wheat production. Therefore, it is necessary to carry out scientific and systematic research on drip irrigated wheat, especially to study the changes of yield and population quality under different drip irrigation patterns, and to find out the characteristics of stem and tiller dynamics and dry matter accumulation of wheat plant in the key water demand period.…”

“…Some studies hold the opposite views; the LAI under equal row spacing planting pattern were significantly higher than that under wide-narrow row planting pattern [37], the lodging rate significantly increases, which is caused by the increases of length in the first and second internodes under narrow row spacing planting conditions, and as the row spacing increases, the lodging rate decreases [38][39][40]. At present, the spacing of drip tubes and wheat row spacing in wheat drip irrigation systems are still in the exploratory stage [11]. The existing one tube serving four rows of wheat pattern was difficult to achieve highly efficient wheat production [9,10].…”

A suitable population structure is the foundation for a high yield of wheat. Studying the changes in yield and population structure of different wheat rows under drip irrigation conditions can provide a theoretical basis for optimizing wheat drip irrigation pattern. In a two-year field experiment, two different water- and fertilizer-demanding spring wheat varieties (XC22 and XC44) were used to study the changes of stem and tiller dynamics, dry matter accumulation, canopy photo-synthetically active radiation (PAR) interception, and canopy apparent photosynthesis rate (CAP) under one tube serving four rows of wheat drip irrigation pattern (TR4, drip lateral spacing (DLS) = 60 cm, wheat row spacing (WRS) = 15 cm) and one tube serving six rows of wheat drip irrigation pattern (TR6, DLS = 90 cm, WRS = 15 cm; TR6L, DLS = 90 cm, WRS = 10 cm and TR6S, DLS = 80 cm, WRS = 10 cm). The results showed that under the condition of equal row spacing of 15 cm, after increasing the number of wheat rows serving by one drip irrigation tube from four (TR4, control) to six (TR6), the yields (water use efficiency) of XC22 and XC44 were lower by 11.19% and 8.63%, respectively. The reduction of yield was related to uneven population growth, specifically as follows: compared with the first wheat row (R1), at flowering stage the leaf area index (LAI) and PAR interception in the third wheat row (R3) of XC22 and XC44 were significantly decreased by 30.02%, 18.69%, 9.59%, and 14.74%, respectively. At the maturity stage, the biomass, plant height, and panicles number of tiller (TPN) in R3 were significantly decreased by 22.15%, 12.34%, 15.46%, 5.24%, 65.07%, and 42.11%, respectively. At the jointing, flowering, and milk-ripening stage, the CAP were significantly decreased by 24.65%, 22.85%, 17.06%, 14.02%, 42.14%, and 32.27%, respectively, the decrease of XC22 were all higher than that of XC44 (except for PAR interception). After the TR6 pattern was processed to narrow the wheat row spacing from 15 cm to 10 cm under the condition of the same drip tube lateral spacing (TR6L) and under the condition of shortening drip tube lateral spacing by 10 cm (TR6S), the yields in R3 of XC22 and XC44 were significantly increased by 20.07%, 18.43%, 30.39%, and 23.80%, respectively, and the increase in yields were related to the improvement of LAI, biomass, plant height, TPN, PAR interception, and increased population photosynthesis. Among the four drip irrigation patterns, for both XC22 and XC44, the yield of TR6S was the closest to that of TR4, and the yields of them were significantly higher than that of TR6 and TR6L.

“…This may be explained by the fact that in wide and narrow row planting, underground irrigation pipes are mostly laid in the middle of the narrow rows and arranged in two rows with one pipe, so that the irrigation water is closer to the crop, allowing the crop to make better use of the irrigation water and thus increasing IWP. Studies on pipe layout are now mostly focused on the comparison of the effects of different pipe-to-row ratios on surface drip irrigation [60,61], while few studies have been conducted on subsurface irrigation. In this meta-analysis, a comprehensive analysis of different pipe layout methods in the literature revealed a significant positive effect on crop yield, WP, and IWP, with an effect of one pipe for one row > one pipe for three rows > one pipe for two rows.…”

Problems such as population growth and climate change have led to a reduction in the use of water for irrigated agriculture, constraining the growth of crops. Subsurface irrigation, as a widely used and efficient water-saving irrigation technology, varies in its effect on increasing yields and saving water under different environmental, management, and other conditions. To investigate the effects of subsurface irrigation on yield, water productivity (WP), and irrigation water productivity (IWP) of three typical crops (wheat, maize, and cotton), this paper conducted a meta-analysis of 528 pairs of studies from 64 papers worldwide to quantify the response of crop yield, WP, and IWP to subsurface irrigation. Overall, the yield, WP and IWP increased by 5.96%, 21.62%, and 27.72%, respectively, with subsurface irrigation compared with surface irrigation. Compared with other conditions, the greatest rate of change was observed at around 200–500 m above sea level, 10–15 °C average annual temperature, 1.45–1.55 g/cm3 soil bulk density, alkaline soil, and when the crops were planted with equal row spacing. Meanwhile, the amount of irrigation water, as well as the subsurface pipeline arrangement and burial depth, had significant effects on crop yield, WP, and IWP. The maximum increase in crop yield, WP, and IWP was favored when the irrigation volume of the subsurface irrigation was reduced by 50–100% compared with surface irrigation or when both had the same volume of irrigation but a mild water deficit. In addition, the yield, WP, and IWP were also affected by fertilization factors. The recommended fertilizer application rates were ≤90 kg P ha–1 (phosphorus) and <150 kg N ha–1 (nitrogen). Compared with surface irrigation, subsurface irrigation showed the greatest yield increase when fertilizer was applied in a one-time application, and the WP and IWP increased significantly when the number of fertilizer applications was <3.

“…In addition, NL treatment exhibited the highest water use efficiency (WUE) and nitrogen fertilizer productivity (PFP N ). WUE is the key indicator of balance between crop water demand and artificial water input in irrigation management [39]. It is closely related to maize yield and water consumption, and is an important indicator to measure whether the water absorbed by maize from the soil is fully utilized [16].…”

Drip tape layout and flow rate are crucial variables that impact the effects of drip fertigation. To investigate the influence of drip tape layout and flow rate on the soil water and nitrogen transport in summer maize in sandy tidal soil, field experiments were conducted for two years. Two drip tape layouts were set: one tape serving for two crop rows (N) and one tape serving for each crop row (E), with two levels of drip flow rate, i.e., high (2 L/h; H) and low (1.3 L/h; L). The results show that under the same drip tape layout, the lower the drip emitter flow rate, the more upright the shape of wetted soil volume. The maximum vertical and horizontal water transport distance under NL treatment was higher than that under NH, EH, and EL treatments. After surface drip fertigation, nitrate nitrogen accumulated near and at the edge of the wetted soil volume. In 2020, under NL treatment, nitrate nitrogen transported to a 55 cm soil layer, which was 22.22%, 71.42%, and 57.14% deeper than that under NH, EH, and EL treatments, respectively. In 2021, nitrate nitrogen could transport to a 60 cm soil layer in both NL and NH treatments. The maximum concentration of ammonium nitrogen was nearby the emitter. Under NL treatment, ammonium nitrogen was transported to 48 and 60 cm soil layers below the emitter in 2020 and 2021, respectively, which was deeper than that observed under NH, EH, and EL treatments. The soil inorganic nitrogen residue of the NL was lower than that of the NH, EH, and EL treatments. Compared with NH, EH, and EL treatments, the two-year maize yield under NL treatment increased by 11.09%, 13.47%, and 8.66% on average, respectively. NL treatment exhibited the highest water use efficiency and nitrogen fertilizer productivity. Therefore, NL treatment (one drip tape serving for two rows with 1.3 L/h flow rate) could promote the absorption of water and nutrients, reduce inorganic nitrogen residue, and to obtain high maize yield in sandy tidal soil.
