摘要
湖南处于北半球亚热带季风气候区,季节性干旱非常严重,干旱季节8～10月是柑橘果实膨大的关键时期,此时如果不及时采取灌溉和抗旱措施,就会极大地影响柑橘的产量和品质。为此,以实地考察和现场调查的形式对湖南省柑橘主产区的灌溉现状、年降雨量、地形地势、土壤条件等进行了较深入的调查,探讨了湖南橘园灌溉方面存在的问题,并对湖南橘园的抗旱节水高品质栽培提出了建议。
Hunan located in area of subtropical monsoon climate in northern hemisphere,which has seriously seasonal drought.The drought season（from August to October） in Hunan is the key period for fruit expanding of orange.If do not apply irrigation to resist drought in time,the yield and quality of orange will be affected greatly.Therefore,the status quo of irrigation,the annual rainfall,the topography and the soil conditions of main orange production area in Hunan were investigated through field survey.Then,the problems existed in irrigation of orangery in Hunan were discussed.In the end,the suggestions for drought-resistant and water-saving cultivation in Hunan orangery were proposed.
