胶东水库灌区果树灌溉效益分摊系数试验研究

在灌溉工程项目经济效益分析和评估中 ,通常应用灌溉效益分摊系数法 ,对粮食作物如冬小麦、夏玉米、水稻方面有一些研究成果 ,但对果树的灌溉效益分摊系数研究较少。山东省胶东地区是国内享有盛名的果树种植区 ,自然条件优越 ,果树种植面积大 ,效益高 ,产业化发展前景好 ,对果树生产效益方面的研究具有实际和很好的代表性。基于上述原因 ,龙口市北邢家水库所在其灌溉试验站对果树灌溉效益分摊系数进行 3年的试验研究 ,主要研究了长把梨、苹果、黄杏 3种主要果树的灌溉效益分摊系数 ,为灌溉水在果树生产中的作用作了定量分析 ,为灌溉工程的经济评价提供了科学依据。

Experimental Research on Allocation Coefficient of Irrigation Effectiveness for Fruit Trees in Beixingjia Irrigation Region

Allocation coefficient method of irrigation effectiveness is usually applied in analysis and assessment of economic benefits of Irrigation project. There are some research results of allocation coefficient for grain crops, such as winter wheat, summer corns and paddy rice, but few results have gained for fruit trees. Jiaodong region of Shandong province is one of main fruit production areas in China and is enjoying a great prospect for fruit industrial production and high economic returns. A field experiment for study the optimal allocation coefficient of irrigation effectiveness for three fruit crops, as pear, apple and apricot, was conducted for three years in management station of Beixingjia reservoir irrigation region in Longkou city of Shandong province. The effects of irrigation water in fruit tree production also are analyzed quantitatively in this paper.
