Abstract:

To make full use of climatic resources and improve land utilization, this paper used the daily average temperature and daily average minimum temperature in Xianyang from 1991 to 2020, the field production data of Xunyi and Weicheng in 2020, and meteorological conditions required for the vegetative growth of cabbage, radish and Chinese cabbage, to design a three harvests a year planting pattern for vegetable production. The results showed that the daily average temperature suitable for the vegetative growth of cabbage was 15℃ to 24℃, and the number of days with the daily average minimum temperature lower than or equal to 12℃ during this period did not exceed 16 days. The daily average temperature suitable for the vegetative growth of radish was 11℃ to 25℃, and the daily relative humidity was more than 47%. The daily average temperature suitable for the vegetative growth of Chinese cabbage was 5℃ to 25℃, and the daily minimum temperature was higher than or equal to -2℃. The cabbage-radish-Chinese cabbage planting pattern could have three harvests a year in northern Xianyang, and the climate conditions of southern Xianyang are not suitable for cold vegetable growth due to high summer temperature.
