Abstract:

In order to ascertain the effects of high temperature and strong light on the young fruit growth of red cartridge kiwifruit in early May 2020 in Guizhou, we selected the real-time meteorological data from 3 national meteorological stations and 19 township’s meteorological stations in the main planting areas of red cartridge kiwifruit in western Guizhou, including the daily average temperature, maximum temperature, sunshine duration and solar radiation in the process of high temperature and strong light, the effects of high temperature and strong light on the young fruit growth of red cartridge kiwifruit in western Guizhou were analyzed. The results showed that continuous high temperature and strong light led to serious sunburn of red cartridge kiwifruit from May 3 to 9. The highest sunburn rate of red cartridge kiwifruit was 33.3% in Duge base, and the second was more than 27% in Longhe base and Xinyao base, and third was more than 22% in the base of Faer, Aga, Miluo, Jichang and Yanjiao. During the fruit growth and development period of red cartridge kiwifruit, when the daily maximum temperature≥35℃, and the total solar radiation≥41 MJ/m2 or the sunshine duration≥10 hours last for 4 days or more, the fruit of red cartridge kiwifruit is prone to sunburn, and when the daily maximum temperature≥38℃, the total solar radiation≥41 MJ/m2or the sunshine duration≥11 hours last for 3 days or more, the fruit of red cartridge kiwifruit will definitely suffer from sunburn.

Key words: high temperature, solar radiation, time of duration, fruit, sunburn, red cartridge kiwifruit
