福建省柑桔种植面积约50多万亩,大部分种植在山区,丘陵坡地,由于地形较复杂,难以进行地面灌溉,主要靠天下雨或大旱时靠人工挑水浇灌。我省雨量充沛,年均降雨1100～2000毫米,但由于年内降雨分布不均,每年9月以后一般降雨较少(主要是台风雨),而在这段时间里恰是柑桔长果最快、需水量最多的时候。若缺水,就会造成柑桔果小、质差、产量低、甚至落叶落果。发展喷灌,就可在这一段时间里给柑桔树补充所需的水分,促进柑桔生长,增加产量,提高果
Fujian Province, citrus planting area of about 500000 acres, most of the planting in the mountains, hills and slopes, due to the complex terrain, difficult to surface irrigation, mainly by the rain or drought by artificial water. Rainfall in our province is abundant with an average annual rainfall of 1100-2000 mm. However, due to the uneven distribution of rainfall during the year, rainfall generally falls below September after each typhoon (mainly due to typhoon), but during this time it is the fastest citrus fruit , When the water needs up. If the water shortage, it will result in small citrus fruit, poor quality, low yield and even falling leaves. The development of sprinkler irrigation, you can during this period of citrus trees to add the required water to promote citrus growth, increase production and improve fruit
