post-sowing irrigation-
The method of close water test has been used for a long time, so richer experience has been achieved. however, it not only takes pains and time, but also consumes raw materials during the close water test because of miscellaneous working procedures such as bricklaying in the two ends of pipe, water - repellent layer plastering, maintaining and water offletting, brick - block backouting after the test, especially in the region short of water and some drainage pipe with prop - pipe construction. in order to satisfy the fast development of municipal construction, new detection methods should be developed
閉水試驗方法因其應用時間較長，目前已積累了較豐富的經驗，但在閉水試驗時，管道兩端砌築磚堵、抹防水層、養護、灌水浸泡，以及試驗后的放水、磚堵拆除等繁雜工序，不僅費工、費時，而且消耗原材料，尤其是在缺水的地區以及頂管施工的無壓管道，這些矛盾更加突出；因此，為滿足迅速發展的市政建設需要，有必要探索新的檢測方法，閉氣試驗就是其中一種，但是閉氣試驗目前還不完善，有待于進一步深入研究。Rice, one of the three major crops in the ningxia irrigation area of yellow river. is widely planted. the traditional irrigation techniques of rice are flood irrigation and deep storage. which need more water consumption and have higher application volumes. with the increase in population, the development of industrial and agricultural production and the uniform catchment agreement for the water resource of yellow river, the supplying and demand contradiction of the water resources in ningxia is more evident, then drang is presented for developing water - saving and efficient agriculture

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。The main issues of the research are put as following : firstly, with the international comparing of market sharing rate and trading competitive index, it was revealed that wheat in china has inferior international competitiveness with a bit rising during current years, however, which is still behind that of the main wheat export countries. secondly, after the international comparing of the main factors that affect the international competitiveness of wheat, it was discovered that chinese wheat has the obvious cost advantage on unit product, while because of the high circulation fee, it results in inferior advantage on the price ; low and unstable quality is another factor which leads to inferior wheat competitiveness ; the input of fertilizer and labor makes little impact on the productivity of chinese wheat, while the input of seeds, irrigation and machine makes a strong impact, so it should be more invested in seeds, irrigation and machine to reduce wheat ' s unit cost. the assistant industries of the wheat, such as breed, production materials and processing industries, have inferior international competitiveness and lagged development
其次，通過對影響小麥國際競爭力的主要因素的國際比較發現：中國小麥單位產品生產成本具有明顯優勢，但由於較高的流通費用，導致在價格上不具有優勢；小麥質量較差、品質不穩定是導致中國小麥國際競爭力較低的主要因素；生產要素中化肥和勞動力投入對中國小麥生產力水平的影響程度較小，而種子、灌溉和機械投入對小麥生產力水平的的影響程度較大，因此小麥生產投入要以增加種子、灌溉和機械的投入為主，代替大量的化肥和勞動力投入，進一步降低小麥單位產品成本，增強中國小麥國際競爭力；中國小麥的上下游輔助產業（包括品種資源、生產資料和加工業）的國際競爭力較弱，發展較為滯后；中國小麥生產者的組織化程度較低嚴重製約了中國小麥質量的提高、流通費用的降低和加工業的發展；小麥生產經營活動本身的特點決定了在充分發揮市場機製作用的基礎上，必須通過政府的宏觀調控來克服其市場機制的失靈，保障市場機制有效運行，但通過國際比較研究發現：中國政府在生產者支持、市場體系建設和國際貿易政策上對小麥的支持水平較低，與提高中國小麥國際競爭力的要求有較大差距，尤其是較低的生產者支持水平和市場體系建設程度制約了中國小麥國際競爭力的提高。Fabrication of the box beam is divided into such parts as reinforcement, formwork, concreting, prestressing, moving and storing of beam, pipe grouting under pressure, end sealing of the beam, water - proof layer on the bridge surface system, protective coating etc. the paper makes description of effective box beam construction technology and workmanship which can be adopted in other projects, such technologies as : manufacturing and fixing of reinforcement, steel reinforcement fixing baseplate, web plate and top plate respectively and lifting the steel skeleton into form, requirements of design and manufacturing and way of utilization for dismantling - erection type formwork and hydraulic formwork, optimization of concrete ratio, concrete pouring process of two ends of beam in priority over the middle, in sequence of first baseplate followed by web plate and top plate at last, concrete pouring in inclined section and in horizontal layer, concrete vibration mainly by external vibrator in assistance with internal vibrator, methods and regulation for steam curing of concrete, dual controls over stress and strain to ensure quality of prestressing workmanship, construction method of effective beam moving by heavy - weight special moving facility, some regulations and key notes about construction of grouting under pressure, beam ends sealing, water - proof layer on the bridge surface system, protective coating
