What fruit trees are most suitable for planting in Guizhou?

The growth, flowering and fruiting of citrus fruit trees are closely related to environmental conditions such as temperature, sunshine, moisture (humidity), soil, wind, altitude, topography and slope direction, among which temperature has the greatest influence. Even if the temperature difference is 0.5℃, sometimes there will be completely different results. The growth and development of citrus need a temperature of 65438 02.5 ~ 37℃.

The day and night temperatures of flower bud differentiation in autumn are about 20℃ and 65438 00℃, respectively, and the soil temperature of root growth is roughly the same as the ground temperature. If the temperature is too low, oranges will be frozen. When the sweet orange is at -4℃ and the satsuma orange is at -5℃, the branches and leaves will be frozen. When the sweet orange is below -5℃ and the satsuma orange is below -6℃, the plants will freeze to death.

Most persimmon varieties began to bear fruit in 3-4 years after grafting, and reached the full fruit stage in 10- 12 years, while the seedlings began to bear fruit in 5-7 years, and the fruiting period exceeded 100 years.

Persimmon is widely planted in China, and it is planted in most provinces except Heilongjiang, Jilin, Inner Mongolia and Xinjiang in the north. Guangxi, Hebei, Henan and Shaanxi are the four main persimmon producing areas, accounting for about half of the country's output.
