新疆奇台县中葛根流域小麦不同节水技术经济效果研究

Study on economic effects of different water saving techniques in wheat in Zhonggegen valley of Qitai county of Xinjiang

通过对新疆奇台县中葛根流域小麦利用大首部自压、塘坝加压、自动化3种滴灌技术及地面灌处理(对照)后的产量、水分利用效率及成本收益率进行对比分析。结果表明,小麦在运用3种节水技术后产量均显著高于地面灌处理,其中自动化滴灌技术产量显著高于大首部自压及地面灌,水分利用效率自动化滴灌技术也显著高于其他两种节水技术,但是从成本收益率而言,塘坝加压滴灌技术优于自动化滴灌技术。采用高效节水技术对于保障昌吉州奇台县小麦稳产增收具有重要意义。

The yield,water use efficiency and cost-benefit ratio of wheat under the use of large head self-pressure,pond dam pressurization and automatic drip irrigation technology and ground irrigation(CK)in Zhonggegen valley of Qitai county,Xinjiang were compared.The results showed that the yield of wheat after using three water-saving technologies was significantly higher than that of ground irrigation.The output of automatic drip irrigation technology was significantly higher than that of large head self-pressure and ground irrigation.The automatic drip irrigation technology of water use efficiency was also significantly higher than the other two.However,in terms of cost-benefit ratio,pond dam pressurization drip irrigation technology is superior to automatic drip irrigation technology.The use of high-efficiency water-saving technology is of great significance for ensuring stable wheat yield and income increase in Qitai county,Changji prefecture.
