Can the weather in Guangdong plant durian trees to bear fruit?

Durian is a pure tropical crop, and its phenological feature is that the daily average temperature of durian is above 22℃. It can be planted in frost-free areas, most of Guangdong province is located in tropical areas, a small part is in subtropical areas, and most areas can be planted.

Because durian can only grow and bear fruit in the high temperature climate all year round, even in the equatorial region, in the highlands above 600m above sea level, durian can not be planted or bear fruit normally because of the low temperature.

Durian tree:

Evergreen tree with long oval leaves, smooth surface and scales on the back. The fruit is spherical, with many hard thorns on the surface and delicious pulp, and it is one of the famous tropical fruits. Native to Malaysia, China, Guangdong and Hainan.

Evergreen trees, up to 25 meters high, with scales at the top of young branches. Stipules are 1.5-2 cm long, with oblong leaves, sometimes obovate oblong, short or acute, rounded or obtuse at the base, shiny on both sides, smooth at the top, scales attached on the back, and lateral veins 10- 12 pairs, with length 15 cm.

Petiole length 1.5-2.8 cm, cymes are slender and drooping, clustered on stems or big branches, with 3-30 flowers in each order; The bud is spherical; Pedicel scaly, 2-4 cm long.

Extended data:

First, the distribution range of durian trees

Origin is Brunei, Indonesia and Malaysia. Some people think it originated in the Philippines.

Durian grows all over Southeast Asia, mainly in Thailand, Malaysia, Indonesia and other places. Other durian growing areas include Cambodia, Laos, Vietnam, Myanmar, India, Sri Lanka, West Indies, Florida, Hawaii, Papua New Guinea, Polynesia, Madagascar, northern Australia and Singapore.

It is cultivated in China, Guangdong and Hainan.

Second, the planting conditions and technology

1, soil

Durian is a tropical fruit, and the choice of planting location needs to be considered in many aspects. The first thing is to consider the climate of the planting area and other fields, so soil selection is also a key point. Because durian needs more nutrients for its growth, it needs to be selected in the area with rich soil fertility.

Secondly, the permeability of soil must be better, and the irrigation and drainage system should be better, preferably the plot with loose upper soil layer and thick lower soil layer, so that the survival rate of durian planting will be greatly improved.

Step 2 diversify

There are many varieties of durian, but the best is Malaysian durian. One of the reasons is indeed Malaysia's unique geographical location, and the second is that durian varieties are resistant to its weather changes.

Therefore, it is necessary to choose varieties suitable for local seasonal changes, so that the survival rate of durian trees planted in this way is high, the yield and quality can be guaranteed, and finally the service life can be prolonged.

3. Temperature

The growth of durian needs a lot of heat, so the temperature in the planting area is relatively high. It is best that the temperature is relatively stable throughout the year, and there is no obvious seasonal change. The optimum temperature for durian growth is generally around 25 ~ 30℃, and the lowest temperature should not be lower than 10℃, otherwise durian trees will stop growing or even freeze to death.

So in some places in China, although durian is planted, the low yield and quality are mostly caused by temperature.
