半乾旱區不同作物與苜蓿輪作對土壤水分恢復與肥力消耗的影響The guardian of the land of an heir who is thus under age, shall take from the land of the heir nothing but reasonable produce, reasonable customs, and reasonable services, and that without destruction or waste of men or goods ; and if we have committed the wardship of the lands of any such minor to the sheriff, or to any other who is responsible to us for its issues, and he has made destruction or waster of what he holds in wardship, we will take of him amends, and the land shall be committed to two lawful and discreet men of that fee, who shall be responsible for the issues to us or to him to whom we shall assign them ; and if we have given or sold the wardship of any such land to anyone and he has therein made destruction or waste, he shall lose that wardship, and it shall be transferred to two lawful and discreet men of that fief, who shall be responsible to us in like manner as aforesaid
未成年繼承人的監護人僅可從該繼承人的封地獲取合理的物產、合理的賦稅及合理的役務，並不得濫用空耗人力物力；如我們委託郡長或任何其他就該土地孳息對我們負責之人以監護未成年人之土地，而此人濫用監護土地，則我們必將責成其作出賠償，同時將封地委託當地兩名守法賢明之士代為管理，由該二人就土地孳息向我們或我們指定的人負責；如我們已將任何此類土地的監護授予或售與他人，而此人濫用監護土地，則立即喪失監護權，封地交由當地兩名守法賢明之士管理，如前所述向我們負責。At present, the studies about the controlled alternate furrow irrigation are focused on how it affects the water physiological indexes, water consumption and yields of crops. but, some problems suc h as the soil infiltrative parameters, irrigating water advancing, water redistribution in soil, calculation of crop water requirement and water consumption, and the upper and lower limit indexes of soil moisture, guiding a field irrigation after the controlled alternative furrow irrigation is implemented in field, have not been researched systematically and deeply. if these problems could not been solved commendably, the popularization of controlled alternate furrow irrigation will be affected
然而，目前有關交替隔溝灌溉的研究還主要集中於這種灌水方式對作物水分生理指標、耗水量和產量的影響方面，而對大田採用這種灌水式后的土壤入滲參數變化情況、作物需水量與耗水量計算、以及指導大田灌溉的水分下限控制指標等與大田生產實際密切相關的幾個問題基本上還沒有進行系統的深入研究，而這些問題如不能得到很好地解決，勢必會對這種灌水方式的推廣應用產生嚴重的影響。Abstract : problems caused in designing and management including configuring regulating devices, deciding spaces of the last pipelines, and working - out irrigation scheme in reason using drip irrigation in green houses and in covered lands are raising in recent years, theose not only affect benefits but also result in failing of projects
文摘:近幾年來溫室、大棚種植蔬菜採用滴灌技術的越來越多，但有些工程無論設計上、管理上都存在一些問題，包括調壓設備的合理配置，按土壤、作物、灌水器及滴灌總水量合理確定毛管（或滴灌帶）的間距，以及按大棚蔬菜的耗水特性合理確定灌溉制度等，上述各項確定的不合理，不但直接影響效益，嚴重時可導致工程失敗，值得重視。In order to maintain the sustainable use of land and water resource, to protect the land from desertification and to make longyangxia reservoir safe, firstly, the spatially disturbed model has been established in which includes dem - based precipitation and runoff, regional transpiration and regional water balance modules in gonghe. secondly, the model of grassland climate potential productivity and the model of grassland productivity modified by plant water demand and stocking intensity factors has been constructed in gonghe. according to the carrying capacity and the actual amount of animals on the grassland, coupled with actual grassland investigation, and by using social - economic data, the grassland productivity, species composition, biotope and the cause of desertification has been analyzed
為了做到對本區的水土資源的可持續利用、防治本區的荒漠化和保護龍羊峽水庫，所以基於dem和已有的氣象、水文長短期觀測和實測數據，首先構建了青海共和盆地降雨、徑流、蒸散和區域水分平衡的分散式模型；進一步在此基礎上，構建了青海共和盆地草地生產力的模型和基於作物水分耗散與放牧因子校正的青海共和盆地草地生產力模型；利用草地載畜能力和現有牲畜量以及社會經濟因子等統計數據，結合實地調查，分析了青海共和盆地草地生產力、物種構成、生境變化和荒漠化成因及其內在驅動因子，並對草地可持續利用做了評價。Moreover, it means improvements in fertilizer use efficiency such as a better nutrient balance to counter depletion of soil nutrients and soil acidification, better application techniques to improve nutrient uptake and to reduce nutrient losses, and overall improvements of crop husbandry
更確切地說：是要通過平衡施肥提高肥料利用率和防止土壤養分過度損耗及土壤酸化，改善施肥技術以提高養分吸收，減少養分流失，從而全面改善作物生產。分享友人
