概括
对于番茄作物,土壤水分 (SM) 灌计划比蒸发透气 (ET) 方法更节水,节约了18.2%的水. 这使得SM调度对于水域有限的地区是理想的.
科学领域:
- 农业科学 农业科学
- 农业学是一种农业学.
- 水资源管理 水资源管理
背景情况:
- 有效的灌计划对农民至关重要,尤其是在水资源稀缺的地区.
- 基于土壤水分 (SM) 和蒸发透气 (ET) 的灌策略的比较对于优化番茄种植的资源使用至关重要.
研究的目的:
- 严格比较基于SM的灌计划与基于ET的灌计划下的番茄作物的产量和用水效率.
- 为了确定不同的灌策略下的西红产量的最佳水应用水平.
主要方法:
- 使用了一个随机的完整块设计 (RCBD),并进行了三次复制.
- 在100%,75%和50%的水位上测试了水需求.
- 用ReplogleBos-Clemmens (RBC) 管道进行灌,用于SM的总水量为229.1毫米,用于ET的总水量为280毫米.
主要成果:
- 两种方法之间没有观察到产量,产量属性或农学特征的显著差异.
- 净收益率优势最高为75%的SM,最低为25%的SM.
- 基于SM的方法显示,与基于ET的方法相比,大约节省了18.2%的水.
结论:
- 基于土壤水分的灌时间表对于像西红这样的水密集型作物,特别是在水资源有限的环境中,优于基于ET的灌时间表.
- 基于SM的灌提供了显著的节水,而不会影响作物产量.
- 通过SM监测优化灌时间表,提高了农业的可持续性.

Adaptations that Reduce Water Loss
25.5K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Design Example: Design of an Irrigation Channel
95
Trapezoidal channels are widely used in irrigation systems due to their cost-effectiveness and efficiency in conveying water. Trapezoidal channels feature a flat bottom and sloping sides, making them stable and easier to construct compared to other shapes. The bottom width and side slope ratio are determined based on the required flow capacity and site conditions. The side slope is kept gentle for unlined channels to prevent soil erosion.Hydraulic parameters in channel design include the flow...
