摘要
对赣南18个县的脐橙园立地自然条件和种植现状进行调查。结果表明:82.1%的土壤为红壤;85.2%的海拔在100～300 m之间;83.5%的坡度在30°以下,其中主要在10°～30°之间,比例达69.3%。另外,赣南脐橙种植面积最大的品种是纽荷尔脐橙,比例达到85%以上;定植时间为2000—2005年的脐橙园比例达到69.3%;种植密度为55～83株/667 m2占59.7%。这表明赣南地区脐橙园建园时间较短,密度合理,增产潜力较大。
The environmental conditions and planting actuality of navel orange orchards in 18 counties in Southern Jiangxi were investigated.The results showed that the soils of 82.1% of the orchards are red and the altitudes of 85.2% of the orchards are 100 to 300 m above sea level.The slope of 83.5% of the orchards are less than 30 degrees,and 69.3% of them are between 10 and 30 degrees.Then principal cultivar is Newhall navel orange,which accounts for more than 85%.Most of orchards were planted during 2000 and 2005,accounting for 89.33%.The planting densities are mostly between 55~83 trees/ha,accounting for 59.7%.It was concluded that the navel orange orchards in Southern Jiangxi are relatively young and reasonably planted in terms of tree density,and thus have great production potential..
