摘要
武都白龙江河谷海拔１３００ｍ以下地带引种油橄榄，单株产果量６年生达１６－４０ｋｇ、１０年生１５８．９７－２００ｋｇ，接近或超过原产地（地中海国家）高产国标准。这里气候属亚热带季风区，空气湿度平均６１％，最热月日均温度２２－２５℃，年降水量４７４．６ｍｍ（夏雨型，６、７、８三个月占５１％），土壤属褐土类，含砂粒、粉粒８５％强，渗透性为１５０ｍｍ／ｈｒ，ｐＨ值７－８，代换性钙２６９ｍｇ／１００ｇ土，具有适应发展油橄榄的良好生态环境。
In the River Valley of Bailongjiang with an elevation of 1300meters in Wudu,olive was introduced,which fruit yield of single-plant is16-40kg in 6 ages and 158.97-200.00kg in 10 ages,and this yield approa-ches or exceeds the standard of highyield grade in the country of origin(the countries around the Mediterranean).The climate of the region is m-onsoon climate of subtropical zone,with the annual average air humidity of61%,the average diurnal temperature of 22-25℃ in the hotest month andprecipitation of 474·6mm per year.The soil group of the region is drab soil,with sand and silt content of 85%,permeability of 150mm/hr,PH value of7-8 and exchangeable calcium of 269mg/100g soil.Therefore,the regionhas a good ecological environment for suitably developing olive.
