汉中地区是我省柑桔主要产地,目前栽培面积约8万亩,本世纪末将发展到20万亩,产量预计近0.5亿公斤。据考证,该地区的柑桔栽培已有400多年的历史,平川、丘陵、浅山都有成片果园。其灌溉条件,除平川部分果园有畦灌和沟灌外,其它尚无灌溉设施。喷灌是一种先进的灌水方法,在十多年来试验示范工作中,具有节省水量、保土保肥和增产等优点,特别适合丘陵浅山区。为了进一步论证和积极推广这一先进灌水方法,1984年,在城固县柑桔育苗场开展了柑桔喷灌试验研究工
Hanzhong is the main producing area of citrus in our province. Currently, the cultivated area is about 80,000 mu. At the end of this century, it will develop to 200,000 mu. The output is expected to reach nearly 50 million kilograms. According to research, citrus cultivation in the region has 400 years of history, Hirakawa, hills, shallow mountains have into orchards. Its irrigation conditions, in addition to Pingchuan part of the orchard irrigation and furrow irrigation, there is no other irrigation facilities. Sprinkler irrigation is an advanced irrigation method. It has the advantages of saving water, preserving soil fertility and increasing yield in more than ten years of experiment and demonstration work, especially suitable for shallow hills in hilly areas. In order to further demonstrate and actively promote this advanced irrigation method, in 1984, citrus sprinkler irrigation experimental research workers in Chenggu County citrus nursery grounds
