摘  要:
依据阿拉尔垦区1961~2005年的降水量、气温、风速、日照时数等气象资料,采用作物生长动态统计模型,分别对该垦区光合、光温、光温水、光温土生产潜力进行了估算。结果表明:垦区光温生产潜力为现实生产力的225.68%,光温资源丰富;光温水生产潜力为现实生产力的21.55%,水分是限制玉米高产的主要因子;光温土生产潜力为现实生产力的108.30%,土壤肥力是限制玉米高产的关键因子。

摘  要:
Based on the meteorological data of the precipitation,temperature,wind speed and sunshine hours from 1961 to 2005 in Alar Irrigated Area,the photosynthetic potential productivity,photo-temperature potential productivity,photo-temperature-water climatic potential productivity and photo-temperature-soil potential productivity were estimated according to the revised model of farm crop growth.The results showed that photo-temperature potential productivity is as 225.68% as realistic productivity;photo-temperature-water climatic potential productivity is as 21.55% as realistic productivity;photo-temperature-soil potential productivity is as 108.30% as realistic productivity.It showed that water and soil fertility are most key factors to restrict the realization of climate productive potential.
