- Abstract:
-
The photosynthetic productive potential, light-temperature potential productivity and light-temperature-water potential productivity were calculated and analyzed by using the data of annual average sunshine hours, temperature, precipitation and evaporation from 1971 to 2000 in Hu County of Shaanxi Province. The results showed that:(1)The photosynthetic productive potential, light-temperature potential productivity, which showed a decreasing tendency and the light-temperature-water potential productivity, which showed an increasing trend with in 30 years; (2) The photosynthetic productive potential, maximum appeared in July, from March to October, it is an important period in the crop production.(3)The contour line of monthly mean light-temperature productive potential change greatly in Hu County, the water factors were the more controllable than temperature. (4) Using greenhouse technology in winter and supplying water resources in summer are effective measures of improving climatic potential productivity in Hu County of Shaanxi Province.
