Special Issue Information

Dear Colleagues,

Plants is launching a new Special Issue titled "The Role of Irrigation in Mitigating the Effects of Climate Change on Crop Production". Climate change is associated with an increasing frequency of extreme weather events, such as heavy rainfall, droughts, and heatwaves, that exacerbate abiotic stresses and plant diseases, challenging global crop productivity. Drought stress has become one of the greatest constraints on global agricultural and ecosystem productivity. Under drought conditions, plants typically face soil and atmospheric water deficits at different growth stages of their life cycle, thereby reducing the harvestable yields. Irrigation is an important strategy to improve the adaptability of crops to global climate change. Especially in areas with limited water resources, irrigation has a significant impact on the physical and chemical properties of soil, such as temperature and humidity, salinity, and the micro-ecological environment, thus changing the growth status of irrigated farmland soil and crops, which plays a vital role in maintaining crop production. At the same time, irrigation will change the humidity and temperature in the air of the local area, resulting in the cooling of farmland evapotranspiration, thereby reducing the heat stress of crops. However, the growth and yield of crops are significantly influenced by the quantity, method, and duration of irrigation water supply, as well as the extent of the water deficit and soil water fluctuation during the growth process. An in-depth discussion of the response mechanism of the farmland soil environment, crop physiological growth, farmland microenvironment, or irrigation area ecosystem to agricultural irrigation events is the theoretical basis for the scientific and rational regulation of irrigation water management. It is very important to better understand how irrigation alleviates the impact of climate change on farmland crop production or the irrigation area of the ecological environment. Therefore, this Special Issue will cover a wide range of crop drought resistance and efficiency enhancement areas, aiming to contribute to the overall knowledge of efficient agricultural water use under climate change conditions.

An appropriate water supply strategy is imperative for obtaining tomatoes of a high yield and quality; the lack of one has caused resource wastage and quality deterioration. To determine the suitable irrigation amount and simulate daily transpiration under these optimal irrigation conditions, a two-year greenhouse cultivation experiment was conducted over 2022–2023. Commencing at anthesis, three distinct irrigation gradients were triggered and designated as irrigation controls with the lower limits set at 80% (T1), 70% (T2), and 60% (T3) of the substrate water-holding capacity. We determined the optimal irrigation amount by ranking the treatments using the TOPSIS method, balancing the tomato yield and quality. A segmented daily transpiration model under optimal irrigation conditions driven by crop and environmental factors was established using the Marquardt method and data from 2022, and the model was validated using data from 2023. The results indicated that T2 was the optimal irrigation amount, with the water use efficiency increased by 18.0%, but with a 10.9% decrease in yield, while the quality indices improved significantly. The R2 values of the segmented model in the flowering and fruit-setting stage and the picking stage were 0.92 and 0.86, respectively, which could provide support for optimized water management for tomato planting in greenhouse substrate cultivation.

The improvement of the simulation accuracy of crop models in different greenhouse environments would be better applied to the automation management of greenhouse cultivation. Tomatoes under drip irrigation in a greenhouse were taken as the research object, and the cumulative evaporation capacity (Ep) of the 20 cm standard evaporation dish was taken as the basis for irrigation. Three treatments were set up in the experiment: high water treatment without mulch (NM-0.9 Ep), high water treatment with mulch (M-0.9 Ep), and low water treatment with mulch (M-0.5 Ep). AquaCrop and DSSAT models were used to simulate the canopy coverage, soil water content, biomass, and yield of the tomatoes. Data from 2020 were used to correct the model, and simulation results from 2021 were analyzed in this paper. The results showed that: (1) Of the two crop models, the simulation accuracy of the greenhouse tomato canopy coverage kCC was higher, and the root mean square errors were less than 6.8% (AquaCrop model) and 8.5% (DSSAT model); (2) The AquaCrop model could accurately simulate soil water change under high water treatments, while the DSSAT model was more suitable for the conditions without mulch; (3) The relative error RE of simulated and observed values for biomass B, yield Y, and water use efficiency WUE in the AquaCrop model were less than 2.0%, 2.3%, and 9.0%, respectively, while those of the DSSAT model were less than 4.7%, 7.6%, and 10.4%, respectively; (4) Considering the simulation results of each index comprehensively, the AquaCrop model was superior to the DSSAT model; subsequently, the former was used to predict 16 different water and film coating treatments (S1–S16). It was found that the greenhouse tomato yield and WUE were the highest under S7 (0.8 Ep), at 8.201 t/ha and 2.79 kg/m3, respectively. Full article
