“…Irrigation increases crop evapotranspiration, while soil water consumption has a negative relationship with irrigation 22 . In this study, the irrigation amount was determined by the water content of different soil layers, which was used in our previous studies 21 , 23 . The mean irrigation amount from the W3 treatment was 95.2 mm, significantly higher than that of the W2 treatment but lower than that of the W1 and W4 treatments, the crop evapotranspiration from W3 was higher than that of W2 but lower that of W1 and W4, however, the mean soil water consumption from the W3 treatment was higher than that of the W1 and W4 treatments by 27.2 and 26.8 mm, respectively (Fig.…”

“…No account was taken of capillary rise, runoff and drainage. When the groundwater table is lower than 2.5 m below the soil surface, as it is at the experimental site, the capillary rising of groundwater is negligible 47 ; runoff can be ignored because of the terrier around the border in the North China Plain, including this experimental site 46 ; the drainage is very little in this study, we assumed that the irrigation and precipitation was absorbed by winter wheat completely, therefore, the drainage was ignored here 21 , 23 .…”

“…In this study, we adapted a method using SI to recharge soil water at critical developmental stages to determine the irrigation amount 21 , a target relative soil water content of 65% of the field water-holding capacity (FC, FC: the maximum hanging capillary water content that soil can be maintained) at jointing and 70% FC at anthesis in three soil layers (0–20, 0–40 and 0–60 cm) were designed. The objectives of this study were, therefore, (1) to investigate the soil water use and crop evapotranspiration of winter wheat to SI, (2) to determine the responses of the winter wheat LAI and PAR capture ratio to SI by measuring soil water content, and (3) to clarify the effect of SI by measuring soil water content on the chlorophyll content, chlorophyll fluorescence, and winter wheat flag leaves senescence.…”

Water shortage threatens agricultural sustainability in China, effective water-saving technologies urgently need to be developed. In this study, five treatments were conducted: rainfed (W0), a local supplemental irrigation (SI) practice (W1), and three treatments in which soil water content was tested prior to SI, specifically at 0–20 (W2), 0–40 (W3) and 0–60 cm (W4) soil layers. Soil water consumption in W3 had no differ with W2 but was higher than W1 and W4. Crop evapotranspiration in W1, W3 and W4 treatments were higher than that in W2. W3 treatment had higher leaf area index than W1 and W4 at later grain filling stages. The mean photosynthetically active radiation capture ratio in W3, especially at 20, 40 and 60 cm plant heights, were significantly higher than those in W1, W2 and W4. The chlorophyll content index, actual photosynthetic activities, catalase and superoxide dismutase activities of flag leaves from W3 were the highest after the middle grain filling stages. W3 treatment obtained the highest grain yield (9169 kg ha−1) and water use efficiency (20.8 kg ha−1 mm−1) in the two seasons. These benefits likely accrued through created a suitable soil moisture environment in W3 treatment.

“…SDI can be used for uniform and frequent water application in many soil and topographic conditions 9,19 . MHI is advantageous, and because of low investment cost, good anti-clogging performance and simple installation, it has been gradually adopted in the NCP in recent years 20 . Therefore, these three irrigation treatments (BI, SDI and MHI) were the focus of this study.…”

In the North China Plain (NCP), the utilization efficiency of cultivated land can be improved by transplanted cotton after winter wheat harvest (TCWWH). To understand the growth, water consumption and economic benefit of TCWWH under different irrigation methods, an irrigation experiment was carried out during 2013–2015 to explore the effects of border irrigation (BI), surface drip irrigation (SDI) and micro-sprinkling hose irrigation (MHI) on the plant development, water use efficiency (WUE) and economic benefit of TCWWH. The results showed that the survival rate of cotton seedlings in the SDI treatment was 12% and 7% larger than that in the BI and the MHI treatments, respectively. SDI increased plant height by 19% and 8% and increased leaf area index (LAI) by 24% and 17%, compared with BI and MHI, respectively. The highest seed cotton yield and better fibre quality were obtained in the SDI treatment, compared to the BI and the MHI treatments. Compared with BI and MHI, SDI reduced the soil evaporation and evapotranspiration (ET) in the field, and resulted in the largest WUE. The net profit generated by the SDI treatment exceeded that of the BI and the MHI treatments by 183% and 23%, respectively. Therefore, SDI can promote the growth of TCWWH and can increase the WUE and the economic benefit of TCWWH, compared with BI and MHI.

“…However, other studies found a quadratic equation between grain yield and evapotranspiration [ 43 – 47 ]. Moreover, Man et al [ 48 ] found that winter wheat grain yield decreased linearly with increasing evapotranspiration. Kang et al [ 47 ] reported that grain yield required a minimum evapotranspiration of 152 mm for winter wheat.…”

The North China Plain is one of the most important grain production regions in China, but is facing serious water shortages. To achieve a balance between water use and the need for food self-sufficiency, new water efficient irrigation strategies need to be developed that balance water use with farmer net return. The Crop Environment Resource Synthesis Wheat (CERES-Wheat model) was calibrated and evaluated with two years of data which consisted of 3–4 irrigation treatments, and the model was used to investigate long-term winter wheat productivity and water use from irrigation management in the North China Plain. The calibrated model simulated accurately above-ground biomass, grain yield and evapotranspiration of winter wheat in response to irrigation management. The calibrated model was then run using weather data from 1994–2016 in order to evaluate different irrigation strategies. The simulated results using historical weather data showed that grain yield and water use was sensitive to different irrigation strategies including amounts and dates of irrigation applications. The model simulated the highest yield when irrigation was applied at jointing (T9) in normal and dry rainfall years, and gave the highest simulated yields for irrigation at double ridge (T8) in wet years. A single simulated irrigation at jointing (T9) produced yields that were 88% compared to using a double irrigation treatment at T1 and T9 in wet years, 86% of that in normal years, and 91% of that in dry years. A single irrigation at jointing or double ridge produced higher water use efficiency because it obtained higher evapotranspiration. The simulated farmer irrigation practices produced the highest yield and net income. When the cost of water was taken into account, limited irrigation was found to be more profitable based on assumptions about future water costs. In order to increase farmer income, a subsidy will likely be needed to compensate farmers for yield reductions due to water savings. These results showed that there is a cost to the farmer for water conservation, but limiting irrigation to a single irrigation at jointing would minimize impact on farmer net return in North China Plain.
