In the most ration of water supplying, yield of crop was enhanced when irrigation ration was increased no matter what planting pattern was applied
無論哪種種植方式，在最大供水量的范圍之內，灌溉定額大，作物的產量水平就高。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。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。
