    遼寧沿海鹽土中鹽分每年隨水移動如下：春季為凍融-蒸發-鹽化期， 5 ~ 9月為灌溉-淋洗-脫鹽水稻種植期，晚秋為蒸發-鹽化期，冬季為相對穩定期。
  2. During wheat and barley bred in winter in sanya, some technological characteristics concerned must be wielded according to the ecological conditions there. 1 ) carefully select materials and avoid planting the materials that can not head in sanya. 2 ) cultivated measure : spread lime before ploughing ; and make furrows during soil preparation. spread funandan in sowing furrows. after every irrigation and heavy rains, surplus water must be drained off immediately and soil must be intertilled in time. it is also a key measure in breeding in winter to prevent and eliminate the plant disease, pest and mice during plant growing period. 3 ) the flowering period of parent for hybridization must be adjusted. 4 ) the criterion for each trait selection to breeding materials should be soften to different degrees

    在三亞冬繁麥類時，應根據當地生態條件掌握好有關技術特點：慎重挑選冬繁材料，盡量避免攜帶可能在三亞不抽穗的材料；栽培措施應注意耕翻前撒施石灰，整地需開廂起壠，播種溝先撒呋喃丹，灌水及大雨後要排除余水，及時鬆土，生育期間注意防治病蟲鼠害；雜交親本應注意調節花期；對育種材料各性狀的選擇標準都要不同程度地放寬。
  3. Under the filtration irrigation, the water content could remained a fit range from 14 to 22 percent in the layer of 20 to 70 cm deep, however, the general irrigation could reduce the moisture utilization during the growing period of the maize. ( 4 ) filtration irrigation could well adjust the soil temperature so that the root system made a sufficient absorption of the moisture and mineral nutrinents

    從土壤含水量測定分析看，在20 70cm土層，滲灌水分含量一直維持在玉米正常所需的14 22范圍內，而漫灌分兩次灌水，在每次灌水前一段時間水分含量要下降到14以下，出現水分脅迫，尤其影響到玉米的前期生長。
  4. 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。
  5. At the same time, using the results of model, the paper provides the optimization irrigation quota and the aim of high yield and high benefit based on the principle that the net benefit of unit water is highestusing the model, we can reasonably distribute the irrigation water for spring - wheat during growing period on the condition of different irrigation quota. through evaluating the comparative yield by the model, the paper gains that the reduction of spring - wheat output is biggest when the irrigation quote is between 100 and 200. the thesis also gains that the corresponding economic irrigation quota is 170 - 120m3 / 667m2. above results can provide scientific reference for irrigation water optimization distribution for crops in the individual irrigation area and the programming of irrigation district

    在現有的生產條件下，可以利用模型在不同的灌溉定額下對春小麥生育期灌水進行合理的分配，並可以利用模型進行作物相對產量的評估，得出當灌溉定額在100 m 200范圍內時，春小麥的產量下降幅度較大，最後得出相應的經濟灌溉定額為170 120m ~ 3 667m ~ 2 ，為今後河套灌區各灌域多作物灌溉水量最優分配以及灌區的規劃設計方面提供了科學參考依據。
