  3. 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。

  7. 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
