Can litchi be planted in Luodian, Guizhou?

Litchi can be planted in Luodian, Guizhou. Choose the right place and pay attention to management.

Analysis and explanation:

Luodian county belongs to subtropical monsoon climate, with the characteristics of early spring, long summer, late autumn and short winter, with sunshine 1350- 1520 hours.

The annual average temperature is 20℃, the extreme maximum temperature is 40.6℃, and the extreme minimum temperature is -3.5℃.

The average annual rainfall is 1335 mm and the frost-free period is about 335 days, so it is called "natural greenhouse".

The annual average temperature of litchi is 20 ~ 30℃, which limits its cultivation and distribution.

Growth and development need high temperature and high humidity, and the optimum growth temperature is 23 ~ 29℃, and 10 ~ 12℃ grows slowly.

Therefore, litchi can be planted in this area.

Training points:

Litchi is mostly planted on hills and slopes. These soils usually have low organic matter content, shallow soil layer and poor water and fertilizer conservation ability. If soil management is not paid attention to, the growth and development of litchi will be seriously affected.

Litchi mycorrhiza is aerobic, and weeding and loosening soil can help loosen soil and promote root development.

Young trees can be combined with management in intercropping crops to weed and loosen soil.

It is hot and rainy in summer and autumn, weeds grow fast, the soil is easy to harden, and weeding and loosening the soil are more frequent; Low temperature in winter and spring, drought, slow growth of weeds, less weeding and loosening the soil.

Young roots are shallow, so according to the range, the loose soil should be shallow, 8 ~ 10 cm, and the depth outside the rhizosphere can reach 15 cm.

Litchi has a long-term unstable fruiting phenomenon, which is common every other year or even several years.

In addition to the influence of climatic conditions, the main reason is poor management.

For scientific management of litchi fruit trees, we should first pay attention to soil management, create a soil ecological environment conducive to the growth and development of litchi roots, make the roots develop vigorously and have strong absorption capacity, and ensure that the aboveground parts of fruit trees can blossom and bear fruit normally.

Secondly, the crown management should be carried out reasonably, and the relationship between vegetative growth and reproductive growth should be adjusted according to the growth and development law of litchi, so that the branches of the fruiting tree will be strong and mature after wintering, and sufficient nutrients will be accumulated to ensure the formation of flower buds and fruits.

Distribution range:

Litchi is mainly produced in southwest, south and southeast of China.

Guangdong, Guangxi, Fujian, Sichuan, Taiwan Province, Yunnan, Guizhou and other places.
