What is a good variety of litchi seedlings? What are the methods of raising seedlings?

Litchi is evergreen Qiobu, the pericarp has scaly protruding, sweet taste, whether fresh pulp or dried litchi, there are a lot of friends like to eat. Fruit growers who want to grow litchi should first choose their own litchi seedlings reasonably, so which varieties of litchi seedlings are better now?

What is a good variety of litchi seedlings?

1. March red

Because the variety matures in the late March of the lunar calendar, it is named Sanyuehong, which is the earliest mature species. The fruit of this variety is heart-shaped, upper and lower sharp; tortoise lobes vary in size, irregular arrangement, suture line is not obvious; skin thick, light red; flesh yellow and white, micro-tough, rough tissue, large core, sweet and sour taste, and residue after eating.

two。 The concubine smiled.

Feizixiao is a variety of litchi, alias Luotangpu, jade purse. Du Mu, a poet in the late Tang Dynasty, wrote: "as soon as you ride the concubine of the world of mortals, no one knows that it is litchi." This is how Feizixiao got its name. The variety has large fruit, thick meat, beautiful color, small kernel, sweet taste and excellent quality and flavor. Mainly distributed in Guangdong, Guangxi and other areas, this variety is one of the mid-early-maturing and high-quality varieties.

3. Number one Red

No. 1 Red Litchi is a mid-ripe litchi variety. There are a small amount of distribution in Shitan, Licheng, Xiancun, Zhu Village and other places. The meat is white and waxy, crisp and juicy. It tastes sweet only when it is fully ripe, with an edible rate of 70%.

2. Methods of raising litchi seedlings

1. Fertilizer application

Fertilization can be started one month after planting. In two or three years, it is mainly to increase the number of roots, promote shoots and strengthen shoots. Master "one shoot, two fertilizers" or "one shoot three fertilizers", that is, when the shoot top buds sprout, apply quick-acting fertilizer based on nitrogen fertilizer to promote the rapid growth of new shoots and grow leaves; when the growth of new shoots basically stops and the leaf color changes from red to green, apply the second fertilizer to make the new shoots quickly turn green and thicken the branches.

The third fertilizer was applied after the new shoots turned green to speed up the ripening of the new shoots. In the first year after planting, there were few roots and small trees, and each plant was mixed with 25 grams of compound fertilizer, 15 grams of urea, 10 grams of potassium chloride and 50 grams of superphosphate. Young trees have few roots and weak ability to absorb fertilizer, and foliar fertilizer can be sprayed 5-6 times a year.

two。 Watering

Irrigation and drainage: water is an important part of litchi trees. The roots of young litchi are few and shallow, which is greatly affected by the change of surface soil moisture. Under the condition of dry soil and dry atmosphere, attention should be paid to watering and moisturizing. In the rainy season, the accumulation of water in the planting hole should be prevented, and the sunken plant should be raised properly to facilitate normal growth.

3. Weed

Litchi mycorrhiza is good for air, weeding and loosening soil help to loosen and aerate the soil and promote the development of root system. Young trees can be combined with inter-crop management to weed and loosen the soil. In summer and autumn, the temperature is high and rainy, the weeds grow fast, the soil is easy to harden, and the times of weeding and loosening soil should be more; the temperature in winter and spring is low, drought, weeds grow slowly, and the times of weeding and loosening soil are less. The roots of young trees are shallow, so according to the scope of loosening the soil should be shallow, 8-10 cm is appropriate, and the depth outside the rhizosphere can be about 15 cm.

4. Shaping

The top is picked when the main pole is 30-60 cm high, leading to 3-4 primary branches with uniform azimuth distribution (main branches). When the primary branches are 40-50 cm long, they are cut off again, resulting in 2-3 secondary branches (secondary main branches). One of the front end is not truncated, so that it extends outward, and the next two branches are picked (cut) to form a third-order branch (lateral branch).

The main branches and many large lateral branches form the skeleton of the crown, so they are called backbone branches. Third-order branches and then pick (truncate) the top, giving birth to fourth-order branches. Do this for another 2-3 times to form a compact tree and increase the number of fruiting mother branches.

5. Pruning

The shaping and pruning of young litchi requires that the young trees can cultivate 30-40 cm high trunk and 3-4 evenly distributed main branches to make them grow at a suitable angle, so the objects of pruning are: cross branches, overdense branches, weak branchlets, and flower ears that do not let them bear fruit. Pruning can be done by pruning, coring, pulling, hanging, stretching and other methods, and the branches that can be cut but not cut can be retained temporarily, so that nutrients can be effectively used to expand the crown.

Pruning should be carried out once a year in winter to cut off overdense shade branches, cross branches, overlapping branches, disease and insect branches, weak branches and withered branches, so that nutrients can be effectively used to expand the crown, ventilation and light in the crown, and reduce diseases and insect pests. After each new shoot is ripe and before the next shoot germinates, leave the overgrown and erect branches 20-30 cm for short cutting.

To sum up, it is the whole content of litchi seedlings. If you also want to plant litchi seedlings, you can consider and choose them according to your local geographical and climatic environment.
