No, litchi and longan should grow in hotter places with more Rain Water, and the climatic precipitation in the north does not match.

Construction of litchi plantation

1. Choose the garden. For high-yield cultivation of litchi, hills or slopes with open terrain, slope below 30 degrees, loose and fertile soil and water source should be selected as ideal for the development of plantations.

2. do a good job in planning. For the selected garden, it is necessary to conscientiously do a good job in the planning of variety selection, zoning, roads, drainage and irrigation systems, fertilizer bases, shelterbelts and auxiliary buildings, so as to facilitate the standardized management of orchards.

3. Determine the planting density reasonably. In general, the reasonable density is that the row spacing is 3.5 × 3.5 meters or 3.5 × 4 meters and planting 50-60 plants per mu.

4. Dig a big hole and put down enough base fertilizer. For those who reclaim and build orchards on hilly land, they shall be opened into equal height terrace belts or equal height trenches according to the row spacing specifications of planting. However, the planting hole is dug according to the selected plant distance, and the specification of the hole is 1 meter long, wide and deep, and 40 kilograms of garbage manure, green manure, barnyard manure and pig and cow manure under each hole are used as base manure.

5. Careful planting. When planting, take the seedling in one hand, gently return to the fine soil in the other hand, return to the soil to cover it to about 2 cm above the root, drench the root water, then continue to return to the mud, and when the return soil is about 10 cm above the ground, form a tree plate, then cover with thatch or stem Osmunda grass to moisturize, stand up next to the seedling, prevent wind and shake pine seedlings to cause dead seedlings, drench water every 3 days after setting, and pay attention to drainage and waterproofing on rainy days. The survival rate was checked and replanted in time after 30 days.

Growth habits of Litchi

Litchi prefers high temperature and humidity, light to yang, and its heredity requires a relatively low temperature during flower bud differentiation, but the minimum temperature will suffer frost damage at-2 ℃. It is most favorable for sunny and warm weather rather than dry and hot during flowering, too low humidity, continuous rain, dry and hot weather or strong north wind are disadvantageous to flowering and pollination. The adverse weather during the flowering and fruiting period will lead to the drop of flowers and fruits, and even the loss of harvest.

It can be seen that litchi is a sunny plant that likes high temperature and humidity, so it is not suitable to be born in the cold north, so it is very necessary for friends who grow litchi to understand the growth habits of litchi. Otherwise, it takes a lot of effort to grow good lychees.
