Can Guangdong Maoming grow durian?

Durian can be planted in Maoming, Guangdong.

Durian is one of the famous tropical fruits, which is native to Malaysia. Some countries in Southeast Asia have more crops, among which Thailand has the most. It is also planted in China, Guangdong and Hainan. Durian is the most famous in Thailand and is known as the "king of fruit". Its smell is strong, people who love it praise its smell, and people who hate it complain about its smell.

Durian is a pure tropical crop. Generally, tropical crops have higher requirements on heat conditions, which are basically frost-free all the year round when the annual absolute low temperature is above 0℃, ≥ 10℃, the accumulated temperature is above 7000 ~ 7500℃, and the annual precipitation is above1000 mm.. Durian, which originated in the tropics or has been planted for a long time, needs high heat conditions. Therefore, it can bear fruit normally in a year with suitable heat and climate conditions.

Phenological characteristics of durian The average daily temperature in the growing area is above 22℃. Frost-free areas can be planted, and parts of China, Hainan and Yunnan provinces can be developed. Because durian can only grow and bear fruit in the climate with high temperature all the year round, even in the equatorial region, the highland above 600m above sea level can not grow durian or bear fruit because of the temperature drop.

Dianbai District is located in a low-grade area south of the Tropic of Cancer and belongs to the south subtropical monsoon climate. The climate features are: the monsoon climate is particularly obvious, the climate is warm all year round, with abundant sunshine and rainfall, water and heat in the same season, little frost and no snow, and the four seasons are like spring.

So Dianbai can grow durian.

Propagation method of durian

1, bud grafting

Almost all dicotyledonous woody plants can germinate and reproduce except monocotyledonous plants and some plants with irregular cambium. The size of a pencil. Now the rootstock stem leaves the soil 10cm. Cut two slits with a width of 0.7cm and a length of 3 ~ 4 cm from top to bottom, cut a knife at the top of the two slits, and pull the skin up to the same length as the bud. Leave a little skin at the lower end of the incision to hold the bud. The process of bud taking is the same as that of anvil water cutting and lifting. After inlaying, use plastic film tape with the width of 1cm to tie it tightly. It is best not to touch the rain for two days.

Step 2 plug in

Seedlings that have not yet grown leaves or become wood are the most suitable rootstocks. Cut the rootstock at a distance of 6 ~ 7 cm, and cut a knife down in the middle of the flat rootstock pile to a depth of about 1cm to form a "V" shape; Take a branch tip with two or three buds equal to the diameter of the anvil stake as a scion, about 8 ~ 10 cm long, cut off 3/4 leaves, flatten the lower end of the scion into a wedge shape, insert it into the slit of the anvil stake, and tie it tightly with a film tape. After that, cover the whole seedling with transparent plastic bags to prevent the scion from evaporation. After about two or three weeks in the shade, if the leaves of the scion do not fall off, it will be successful.

3. Wharf

Only suitable for a small number of propagation, plastic bags planted seedlings, about six or seven months can be used as rootstocks. The branch size of scion is similar to that of rootstock, and the most ideal technology is upright nutrition.

Step 4 cut

The branches used are about 15cm long and the diameter is as big as chopsticks. There should be several leaves and buds, and two-thirds of each leaf should be cut off to prevent water from evaporating. The branch tips are obliquely cut or cut 1 cm from bottom to top, coated with a layer of hormone rooting agent, inserted into a wet sand cup, and watered in a greenhouse with poor light. After seven or eight weeks, if the leaves don't fall off and the young roots grow, they can be transplanted into plastic bags.

5. Abdominal connection of branches and tips

The size of rootstock can be arbitrary, as long as it has grown into wood, the cortex is easy to peel off, the cutting tip is arbitrary, and the cutting process is similar to bud grafting. Select 10cm long robust buds that have not yet opened leaves and are not yet mature as scions. The length of the scion is slightly shorter than that of the rootstock incision. Insert it into the rootstock incision, tie it tightly with plastic tape, then wrap it tightly with transparent plastic paper and put it in the shade. Cut off the tape after two weeks, but don't remove the tape until the branches grow out.
