Effects of Chlorine-Based Fertilizers on Tomato Growth under Soilless Culture

引用

Phyton-International Journal of experimental Botany 2025年第1期94卷 243-250页

作者： Fei Li Meili Ding Hui Yuan Siping Wang Bin Liang college of agriculture and forestry Technology Weifang Vocational CollegeWeifang262737China college of resources and Environment Qingdao Agricultural UniversityQingdao266109China

This study investigated the effects of chlorine-based fertilizers under varying nitrogen solution concentrations in a soilless culture system. The experiment included four nitrogen solution concentration levels, with nitrogen concentrations of 6 mmol/L (C1), 12 mmol/L (C2), 18 mmol/L (C3), and 24 mmol/L (C4). Each nutrient concentration level was further divided into four chloride ion treatments (R1, R2, R3, and R4), where 100%, 60%, 33%, and 0% of the NH4+ and K+ ions were derived from NH4Cl and KCl, respectively. The length, surface area and volume of root were significantly higher by 25.3%~136.9%, 40.1%~173.1%, 27.9%~178.0%, respectively, in the R4 treatment than in the R1 and R2 treatments at flowering stage. The aboveground biomass and yield in the R4 treatment were significantly higher, by approximately 15.6%~43.5% and 16.6%~28.6%, respectively, than in the R1, R2, and R3 treatments at the picking stage. The C3 and C4 treatments significantly decreased biomass and yield by 31.9%~50.2% and 20.7%~50.5%, respectively, compared to the C1 and C2 treatments at the picking stage. Besides, the higher nutrient solution increased the incidence of blossom-end rot. In conclusion, high concentrations of chloride ions in nutrient solutions, especially when the Cl− concentration exceeded 10 mmol/L, have been shown to inhibit tomato growth in soilless culture systems. Therefore, replacing sulfur-based fertilizers by chlorine-based fertilizers is not recommended for tomato production under the studied conditions.

Spatio-temporal evolution of complex agricultural land use and its drivers in a super-large irrigation district (Hetao) of the upper Yellow River Basin (2000–2021)

Journal of Geographical Sciences 2025年第2期35卷 273-301页

作者： LI Xinyi SUN Chen XIAO Xue LI Zhengzhong MA Xin WANG Jun XU Xu Chinese-Israeli International Center for Research and Training in agriculture College of Water Resources &Civil Engineering China Agricultural University Institute of Environment and Sustainable Development in agriculture Chinese Academy of Agricultural Sciences Shahaoqu experimental Station Jiefangzha Department Inner Mongolia Hetao Irrigation District Water Resources Development Center Water resources Research Institute of Inner Mongolia college of Economics & Management China Agricultural University

Accurate spatio-temporal land cover information in agricultural irrigation districts is crucial for effective agricultural management and crop production. Therefore, a spectralphenological-based land cover classification(SPLC) method combined with a fusion model(flexible spatiotemporal data fusion, FSDAF)(abbreviated as SPLC-F) was proposed to map multi-year land cover and crop type(LC-CT) distribution in agricultural irrigated areas with complex landscapes and cropping system, using time series optical images(Landsat and MODIS). The SPLC-F method was well validated and applied in a super-large irrigated area(Hetao) of the upper Yellow River Basin(YRB). Results showed that the SPLC-F method had a satisfactory performance in producing long-term LC-CT maps in Hetao, without the requirement of field sampling. Then, the spatio-temporal variation and the driving factors of the cropping systems were further analyzed with the aid of detailed household surveys and statistics. We clarified that irrigation and salinity conditions were the main factors that had impacts on crop spatial distribution in the upper YRB. Investment costs, market demand, and crop price are the main driving factors in determining the temporal variations in cropping distribution. Overall, this study provided essential multi-year LC-CT maps for sustainable management of agriculture, eco-environments, and food security in the upper YRB.
