What fruit trees are most suitable for planting in Guizhou?

1. Citrus

The growth, development, flowering and fruiting of citrus fruit trees are closely related to environmental conditions such as temperature, sunshine, water (humidity), soil, wind, altitude, terrain and slope aspect. These conditions affect the maximum number of temperatures. Even a difference of 0.5°C in temperature can sometimes produce completely different results. The growth and development of citrus requires a temperature of 12.5 to 37°C.

Flower bud differentiation in autumn requires day and night temperatures of about 20°C and 10°C respectively. The soil temperature for root growth is roughly the same as that of the aboveground part. If the temperature is too low, the citrus will be frozen. Sweet oranges will be frozen at -4℃. Wenzhou satsuma mandarins will freeze their branches and leaves at -5℃. Sweet oranges will be frozen below -5℃. Wenzhou satsuma mandarins will be frostbitten below -6℃. Sweet oranges - Below 6.5℃, Wenzhou mandarin oranges below -9℃ will freeze the plants to death.

The main citrus producers are 10 provinces (cities and districts) including Zhejiang, Fujian, Hunan, Sichuan, Guangxi, Hubei, Guangdong, Jiangxi, Chongqing and Taiwan, followed by Shanghai, Guizhou, Yunnan, and Jiangsu It is also grown in other provinces (cities), Shaanxi, Henan, Hainan, Anhui and Gansu.

2. Dragon fruit

Dragon fruit is a tropical and subtropical fruit that likes light and tolerates shade, heat and drought, and likes fertilizer and tolerates barrenness. It grows rapidly in a warm, humid and well-lit environment. When cultivated in the open field in spring and summer, it should be watered more often to keep the root system in a strong growth state. In rainy weather, it should be drained in time to avoid infection by bacteria and causing stem rot. Its stems can grow even when attached to rocks. The plants are extremely wind-resistant and can withstand typhoons as long as the supports are firm.

Dragon fruit is resistant to low temperatures of 0℃ and high temperatures of 40℃, and the optimal temperature for growth is 25-35℃. Dragon fruit can adapt to a variety of soils, but neutral soil and weakly acidic soil that contains a lot of humus and retains water and fertilizer is better.

Origin: Costa Rica, Guatemala, Panama, Ecuador, Cuba, Colombia and other places in Central America. Later it was introduced to Southeast Asian countries such as Vietnam and Thailand, Taiwan Province of China, and Hainan, Guangxi, Guangdong, Fujian, Yunnan and other provinces and regions in mainland China.

Loquat likes light and is slightly tolerant of shade. It likes warm climate and moist, well-drained soil with fertilizers and water. It is slightly tolerant of cold, but not tolerant of severe cold. It grows slowly, with an average temperature of 12~ It can grow well in areas with temperatures above 15 degrees Celsius, no lower than -5℃ in winter, and no lower than 0℃ during flowering and young fruit stages.

Produced in Gansu, Shaanxi, Henan, Jiangsu, Anhui, Zhejiang, Jiangxi, Hubei, Hunan, Sichuan, Yunnan, Guizhou, Guangxi, Guangdong, Fujian, and Taiwan.

4. Persimmon

Persimmon tree is a deep-rooted tree species and a positive tree species. It likes warm climate, sufficient sunshine and deep, fertile, moist and well-drained soil. It is suitable for growing In neutral soil, it is more tolerant to cold, but more tolerant of barren soil, strong drought resistance, and intolerant to saline-alkali soil. Most varieties of persimmon trees begin to bear fruit 3-4 years after grafting, and reach peak fruiting period in 10-12 years. The fruit trees begin to bear fruit at 5-7 years old, and the fruiting period is more than 100 years.

Persimmon is widely grown in my country. It is grown in most provinces and regions except for the cold areas in the north such as Heilongjiang, Jilin, Inner Mongolia and Xinjiang. Guangxi, Hebei, Henan and Shaanxi are the four main persimmon producing areas, accounting for about half of the country's output.

5. Sweet carambola
