At the same time the study analyse the structural system of the index and it ' s weight with the ahp, and choose soil quality, soil thickness, the content of organic matter, terrain, elevation and the ration of irrigated guarantee as gradation index and choose soil quality, soil thickness, the content of organic matter, terrain, elevation, the ration of irrigated guarantee, the condition of traffic, the distance from the central city, the scatter degree of field, the neat degree of field, loss of water and erosion of soil and land contamination as classification index. at the same time the study emphasize the effect of the condition of ecological condition and environmental contamination
採用層次分析法對該區域農用地分等定級的指標體系及其權重進行了研究，選擇表層質地、土層厚度、有機質含量、地形、海拔、灌溉保證率等6項指標參與分等評價，選取表層質地、土層厚度、有機質含量、地形、海拔、灌溉保證率、對外交通狀況、距市中心距離、田間道路狀況、田塊分散度、地面平整度、水土流失、土地污染等13個因子分指標區進行定級評價，強調了生態條件及其環境污染狀況在農用地分等定級中的作用。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。Factors such as soil texture, landscape, climate, irrigation, crop type, and nitrogen management influence intensity of no3 - loss through leaching
土壤質地、地貌、氣候、灌溉、作物類型和氮素管理等因素影響到淋失的強度。Water application intensity - calculation principles and measurement methods
灌溉強度.計算原理和測量方法According to the correlativity between stomatal conductance and soil moisture, root system distribution and soil water profile, these greenbelt should irrigate when soil moisture is high, and their scheming wetted soil layer depth is shallow in slow consumption stage ; irrigate when soil moisture is low, and their scheming wetted soil layer depth is deep in quickest consumption stage ; irrigate when soil moisture is higher, and their scheming wetted soil layer depth is deeper hi slower consumption stage
在草坪弱、泡桐中耗水期時，土壤高含水量時即須淺層灌溉補水，以滿足其萌發需要；中、強耗水期，可低土壤含水量時深層灌溉補水；微耗水期，為安全越冬，又需中深層灌溉補水。最大灌水定額由灌溉飽和點、補償點和計劃濕潤深度確定。There are many urgent unsolved problems in spray irrigation, such as the influence of wind, uniformity of spray irrigation, degree of atomization, intensity of spray irrigation, structure of sprinkler, etc. especially, how to decrease the engineering investment is the most primary issue
噴灌中急待解決的問題很多，諸如風力影響、噴灌均勻度、霧化程度、噴灌強度、噴頭構造等的問題，噴灌工程實踐表明：降低噴灌工程投資等問題是節水灌溉工程中的首要問題。Takes tugou in yanchi county as an example, according to the water resources of tugou, with the implementation of farmland irrigation developments and water irrigating system and adjustment of the agriculture plants, the carrying out of technigues of the agriculture multi - plants, making tugou village a good model of water using efficiently, which provides theoretical basis for the same dry sandy area
以鹽池縣土溝村為例，根據土溝村水資源的條件，通過加強農田水利建設、推行節水灌溉制度、調整農業種植結構以及多相農業節水種植技術的實行，使土溝村在高效用水方面具有一個良好的用水優化模式，為乾旱風沙區同類地區的井灌節水利用方面提供一定的理論依據。分享友人
