Based on the observation made on the main crops such as wheat, corn, cotton etc., the observed data from the limited irrigation test for three years are obtained, and then the test data are analyzed with the theory of soil moisture movement and the model of farm crop ' s evaporation is established under the condition of insufficient irrigation
摘要通過對小麥、玉米、棉花等主要農作物的分階段受旱試驗,獲得了三年的限額灌溉試驗觀測數據;採用非充分灌溉條件下的土壤水分運動理論分析試驗數據,建立了限額灌溉條件下的作物蒸發蒸騰模型。Facing to the reduction of the water diversion from the yellow river for hetao irrigation district inner mongolia autonomy, and giving attentin to agriculture production and improvement of salinization, this paper researches optimization model of district water - saving irrigation water management. the paper also quests for the optimization model of crop irrigation system and the optimization irrigation strategy aiming at the short of water for agriculture. in order to save water and use water high efficiently, this paper researches the change regulation of irrigation system of spring - wheat that is the important crop in the irrigation districted establishes the multidimensional dynamic model of irrigation rules of spring - wheat. lt also makes the simulation model of salt leaching of fall irrigation rules during non - growing period, and sorts the elements influencing water - saving of irrigation system
在內蒙古河套灌區的引黃水量減少又要兼顧灌區的農業生產和土壤鹽漬化向良性發展的形勢之下,本文針對灌區內區域灌溉水管理的現狀,對灌區內區域節水灌溉水管理優化模型進行了研究。研究針對農業水資源短缺的現狀,在節水灌溉條件下,對作物的灌溉制度進行優化模型探索,尋求最優灌溉策略。全文圍繞節水與高效用水,綜合應用了系統分析、灌溉排水及節水灌溉的原理和知識,研究了灌域內主要作物春小麥的灌溉制度的變化規律,建立了春小麥灌水制度的多維動態優化模型;建立了非生育期的秋澆制度的鹽分淋洗模擬模型;對節水灌溉水管理的影響因素的重要性進行了排序研究。In field study, the expenment on nitrogen transport and transformation in soils with different irrigation ( with both ground water and sewage effluent ) and fertilization levels has been conducted. with considenng the n - uptake, nitrification and demtrification processes, a model for describing no2 - - n transport and transformation in unsaturated soil has been applied. results show that, the n03 + - n accumulating in soil is contributed more by fertilization but lees by irrigation with sewage effluent, and the model can be used to simulate no3 - - n transport in soils
在室外進行了不同清污水灌水量與施肥條件下氮素遷移轉化試驗,同時進行了考慮根系吸收,硝化和反硝化的田間非飽和no _ 3 ~ - ? n遷移轉化模型的數值模擬,研究結果表明與施肥相比,污水灌溉對土壤中no _ 3 ~ - ? n累積的貢獻較小,所建立模型可用於模擬no _ 3 ~ - ? n在土壤中的遷移。In this paper, based on the tracing field infiltration tests into frozen and unfrozen soils with three species of soil texture and eight species of soil structure in seasonal frozen soil regions during three overwinters, the basic infiltration characteristics, reduction infiltration mechanism and major factors influencing soil infiltration characteristics are studied all - sidedly and systematically. to master frozen soil infiltration characteristics and supply scientific directions for winter irrigation
本文基於季節性凍土區田間三種質地、八種結構歷時三個越冬期的凍土、非凍土入滲跟蹤試驗,全面、系統地研究了凍融土壤的入滲特性、阻滲機理和影響凍融土壤入滲特性的主要因素,掌握凍融條件下土壤水分入滲特性,為冬灌及農業節水灌溉提供科學依據。Deep pipe irrigation can be especially useful on slopes and in crusty soils where surface applied water will run off
描述:深度管道灌溉在斜坡和硬質土壤環境中非常適用,因為在那些地方地表灌溉浪費水資源。Because of the unreasonable restriction of actual models, soil water content at the end of the stage that its sensitivity parameter is small is always close to the wilting coefficient, this makes planting risk. to deal with the planting risk of inadequate irrigation schedule, this paper develops a new multi - objective model for inadequate irrigation schedule programming, and uses the staged multi - dimensional fuzzy optimization method to get the decision - making
針對現行非充分灌溉制度優化設計模型中約束的不合理性,致使作物在敏感性指數小的階段末土壤含水率易趨于凋萎系數,生產中存在風險的不足,本文提出了考慮作物種植風險指標情況下,非充分灌溉制度的多目標優化模型;並採用本文提出的多維多目標動態規劃方法進行模型求解。分享友人
