“…The evaporation amount was measured at 08:00 AM for each irrigation frequency; the irrigation was initiated after the measurement. The irrigation amount (W) was calculated according to formula (1) [23,40]. The irrigation times and amounts were recorded (see Table 1), taking k cp = 1:0 as an example to draw the irrigation time and irrigation amount (see Figures 4 and 5].…”

“…The selection of the distance between orifices in the capillary and the irrigation amount has a direct impact on soil water and heat, ventilation, mineralization and decomposition rate of organic matter, nitrogen transformation, microbial biomass, activity, etc. [23,24]. Therefore, the study on the emission of greenhouse gases in greenhouse tomato farmland and the formation mechanism of tomato yield is of great significance to obtain the best balance point of water saving and yield increase of greenhouse tomato and to formulate measures to reduce greenhouse gas CO 2 emissions in vegetable fields of MSPF.…”

“…Previous studies have found that reducing the irrigation amount can reduce the soil respiration rate, and excessive irrigation will also inhibit the increase of the soil respiration rate [34,35]. In tomato and maize under drip irrigation, the irrigation amount was positively correlated with yield and soil CO 2 emission [36][37][38] and negatively correlated with water use efficiency [23].…”

Microsprinkler irrigation under a plastic film in the greenhouse (MSPF) is a water-saving way which adopts the porous discharge form of a pipe under the plastic film. The effects of different micropore group spacings (L1:30 cm, L2: 50 cm) and irrigation amounts [I1: 0.7 Epan; I2: 1.0 Epan; and I3: 1.2 Epan (Epan is the diameter of 20 cm standard pan evaporation, mm)] of the MSPF on the soil respiration and yield of tomato were studied. A completely randomized trial design was used, and drip irrigation under plastic film (CK1) and microsprinkler irrigation (CK2) were also used as controls. The results showed that under the same irrigation amount, the soil respiration rate, tomato yield, and water use efficiency (WUE) of MSPF in spring and autumn are 8.09% and 6.74%, 19.39% and 4.54%, and 10.03% and 2.32% higher than those of CK1, respectively; they are significantly increased by 31.02% and 20.46%, 49.22% and 38.38%, and 58.05% and 34.66% compared with those of CK2, respectively, indicating that MSPF increased the amount of CO2 emission, but tomato yield and WUE were effectively improved, and a dynamic balance was reached among them. Compared with the 50 cm micropore group spacing, the spring and autumn tomato yields and WUE under the 30 cm micropore group spacing were significantly increased by 16.00% and 13.01% and 20.85% and 14.25%, respectively, and the micropore group spacing had no significant effect on the soil respiration rate in both root and nonroot zones. When the I increased from 0.7 Epan to 1.2 Epan, the soil respiration rate and yield in the root and nonroot zones of the spring and autumn tomatoes increased at first and then decreased, and the WUE showed a decreasing trend. The relationship of soil respiration rate between the nonroot and root zones obeys a logarithmic function, and the soil respiration rate in the nonroot zone has a quadratic curve relationship with the yield of tomato. This study can provide data support for the development of water-saving irrigation and yield increase of facility agricultural tomato and the analysis of the soil carbon cycling mechanism.

“…(3) Economic policy: an increasing number of studies have found that economic policy (including subsidy policies, water price policies, and water use restrictions) can affect the preferences and behaviors of peasant households, and provide them with incentives to use water-saving irrigation technology and to change their crop planting structure, which leads to changes in the water use efficiency of agricultural irrigation [36][37][38]. In addition, some scholars have found that other factors such as geographic spatial distribution [30,39], irrigation strategies and planting patterns [40][41][42], and crop types [9,43] have an impact on the water use efficiency of agricultural irrigation.The diversity and complexity of influencing factors make it difficult to predict irrigation water use efficiency and, to our best knowledge, there are few predictive studies on irrigation water use efficiency. Most studies take a biological perspective and measure the water use efficiency of specific crops under different irrigation conditions [44][45][46] or predict the irrigation water demand for a period of time in Sustainability 2019, 11, 7103 3 of 19 Sustainability 2019, 11, 7103 4 of 19of technological diffusion mechanism, the conditional convergence model, is the core tool to predict irrigation water use efficiency.…”

Technological changes in water use efficiency directly influence regional sustainable development. However, few studies have attempted to predict changes in water use efficiency because of the complex influencing factors and regional diversity. The Chinese Government has established a target of 0.6 for the effective utilization coefficient of irrigation water, but it is not clear how the coefficient will change in different provinces in the future. The purpose of this study is to predict irrigation water use efficiency changes using a conditional convergence model and combined with the shared socioeconomic pathways (SSPs) scenario settings and hydro-economic (HE) classification to group 31 Chinese provinces by their different economic and water resources conditions. The results show that the coefficient exponentially converges to 0.6 in half the provinces under SSP1 (sustainability), SSP2 (middle of the road), and SSP5 (conventional development) by 2030, whereas SSP3 (fragmentation) and SSP4 (inequality) are generally inefficient development pathways. HE-3 provinces (strong economic capacity, substantial hydrological challenges) achieve the greatest efficiency improvements (with all coefficients above 0.6), and SSP1 is a suitable pathway for these provinces. HE-2 provinces (strong economic capacities, low hydrological challenges) have relatively low efficiency because they lack incentives to save water, and SSP1 is also suitable for these provinces. For most HE-1 provinces (low economic capacity, low hydrological challenges), the coefficients are less than 0.6, and efforts are required to enhance their economic capacity under SSP1 or SSP5. HE-4 provinces (low economic capacity, substantial hydrological challenges) would improve efficiency in a cost-efficient manner under SSP2. utilization efficiency of natural resources, is a possible way to solve the current dilemma of sustainable development [3,4], because it has a direct impact on the total scale of natural resource utilization, and thus directly influences whether the regional social economy is in a sustainable development state [5,6]. Technological change in agriculture irrigation water use efficiency is of fundamental significance for solving water scarcity and increasing crop productivity, and achieving highly efficient irrigation is crucial to balancing water resources input and sustainable agricultural economic growth [7][8][9].The theory of technological change generally distinguishes two types of technological change: technological catch-up and technological diffusion. Technological catch-up concerns the knowledge production function and occurs through the mechanism of learning by doing. It requires continuous additional capital inputs and manufacturers, and the labor force must constantly learn and master new skills in the production process, which brings about extensive progress in social productivity [3,[10][11][12]. Technological diffusion is brought about by technological transmission and is mainly realized through open trade, technology transfer,...

BACKGROUND: Water shortage is the main factor affecting agricultural production in the vast arid and semi-arid areas of northern China. Using proper irrigation methods can optimize the efficiency of water use and improve the quality of agricultural products. This study investigated the effect of different irrigation levels on the quality of 'Honeycrisp' apples grown in the Loess Plateau of northern China. RESULTS: Different irrigation levels were applied to the 'Honeycrisp' apple trees via root irrigation using ceramic emitters that provide saturation levels of 75-90% ⊔ f (S1, where ⊔ f is the field capacity), 60-75% ⊔ f (S2), 45-50% ⊔ f (S3) and no irrigation treatment (CK). Compared to the apples from the CK group, the water content, transverse diameter, individual fruit weight and titratable acid content of S1 and S2 group apples increased significantly. However, their hardness, soluble solids and total sugar content decreased significantly. The phenolic acid content of apples also changed with the irrigation levels. The chlorogenic acid content of apples increased with increased irrigation volume, while the hyperoside, protocatechuic acid and caffeic acid content decreased. Total phenolic and flavonoid contents of fruits were the highest in S2 group apples. They also had the strongest ABTS and DPPH free radical scavenging capacities.CONCLUSION: The volume of irrigation applied through ceramic emitters significantly impacted the quality of 'Honeycrisp' apples grown in loess areas. Considering water conservation and improving fruit quality, the most suitable ceramic root irrigation level was observed to be 60-75% ⊔ f (S2).
