我省位于黄土高原中部,自然条件具有海拔高,光照强,昼夜温差大,土层深厚等北方果树生长的优势条件,因而生产的潜力很大。但由于降水不足和年降水分布不均所造成的干旱问题,限制了果树的发展。人工灌溉是解决这一问题的根本途径,但受到水资源的限制, The province is located in the middle of the Loess Plateau, natural conditions with high altitude, light intensity, temperature difference between day and night, soil depth and other advantages of the growth of northern fruit trees, and thus the potential for production. However, due to lack of precipitation and uneven distribution of annual precipitation caused by the drought, limiting the development of fruit trees. Artificial irrigation is the fundamental solution to this problem, but due to the limitation of water resources,
