农田灌溉模式的优化路径选择

Optimal Path Selection of Farmland Soil Irrigation Mode

目的:探讨不同灌溉模式对棉花生长的影响。方法:通过对5种处理模式下土壤电导率、离子浓度以及评价棉花生长状况关键指标的测定,选取对棉花生长影响最为显著的5种离子(K^(+)、Na^(+)、Cl^(-)、HCO3-、SO_(4)^(2-)),在应用小波去噪进行数据清洗的前提下,构建回归模型。结果:SO_(4)^(2-)与Cl^(-)浓度过高会对棉花生长起抑制作用,在5种处理模式,模式4不仅节水,而且能保证土壤中SO_(4)^(2-)与Cl^(-)浓度在合理的浓度范围内,该处理模式的总体效果最佳。结论:模式4总体效益最佳,是最优的灌溉模式。

Objective:In order to explore the effects of different irrigation modes on cotton growth.Method:Through the determination of soil electrical conductivity,ion concentration and key indicators for evaluating cotton growth under five treatment modes,selection of cotton The 5 most significant ions(K^(+),Na^(+),Cl^(-),HCO3-,SO_(4)^(2-)),on the premise of ap⁃plying wavelet denoising for data cleaning,construct a regression model.Result:The results showed that too high con⁃centrations of SO_(4)^(2-)and Cl^(-)would inhibit the growth of cotton.In the case of 5 treatment modes,mode 4 not only saved water,but also ensured that the concentrations of SO_(4)^(2-)and Cl^(-)in the soil were reasonable.Within the concentration range of,this treatment mode has the best overall effect.Conclusion:Mode 4 has the best overall benefit and is the opti⁃mal irrigation mode.
