Abstract:

Using the meteorological observation data from 1987 to 2022 of Kashi National Reference Climate Station and the growth data of Pistacia vera phenology and temperature in the same period in Shufu County, the suitable planting area of Pistacia vera in Shufu County was analyzed by using the correlation and regression analysis. And through analyzing the spatio-temporal distribution of frost in spring, frost damage in winter, high temperature stress in summer during the Pistacia vera growing time, the meteorological disasters that affecting Pistacia vera growth were determined. The results showed that the growth period of Pistacia vera from bud germination to dormancy was about 270 d in Shufu County, the average temperature increase from late February to mid-April was 0.8-1.2℃/10 a, and the bud swelling, bud opening, leaf spreading and flowering stage advanced 4.5, 5.9 and 4.6 d/10 a, respectively, indicating that the climatic warming advanced the spring phenology of Pistacia vera in Shufu County. We should pay attention to the diseases caused by overwinter, high temperature and humidity.
