生育期灌水 meaning in English

irrigation in growing period

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
在现有的生产条件下，可以利用模型在不同的灌溉定额下对春小麦生育期灌水进行合理的分配，并可以利用模型进行作物相对产量的评估，得出当灌溉定额在100 m 200范围内时，春小麦的产量下降幅度较大，最后得出相应的经济灌溉定额为170 120m ~ 3 667m ~ 2 ，为今后河套灌区各灌域多作物灌溉水量最优分配以及灌区的规划设计方面提供了科学参考依据。
