Management Technology of Guiwei Litchi

There are many places where litchi is produced, but only Lingnan is famous; there are many varieties of litchi, but there are only Feizixiao, Nuomici and Guiwei. Lingnan sweet-flavored litchi is famous for its sweet core and a little fragrance of sweet-scented osmanthus. So how do you grow delicious cinnamon-flavored litchi?

Management Technology of Guiwei Litchi

1. Timely fertilization

After hanging a large number of fruits, Guiwei litchi consumes a lot of nutrients, and the leaves are easy to turn light yellow, which will of course affect photosynthesis. The autumn shoots extracted for the first time will appear irregular, and even affect the germination and timely ripening of the second and third autumn shoots. Therefore, it is very important to increase the yield by topdressing and watering at the right time, improving the tree potential and ensuring that the last autumn shoot can be produced in the middle of October.

2. Moderate pruning

Guiwei litchi tree shape is relatively loose, after fruit picking, it is necessary to moderate retraction and pruning, slightly cut off the top section of the fruiting branch, cut off the bibcock, to the middle and lower part of the fruiting branch last year. And cut off some falling branches. The buds and branches were thinned when 5~10cm was extracted from autumn shoots, 2 shoots were left for each basal branch of autumn shoots in the first time, and 1 branch for other autumn shoots. This can promote the germination of new shoots.

3. Protect flowers and fruits

Guiwei litchi is easily affected by low temperature in the early stage of flower ear growth, which affects the flowering rate and fruit setting rate. Spraying nucleotides can not only effectively enhance leaf photosynthesis, but also enhance the ability of resistance to low temperature, overcast and rainy weather, which is helpful to improve the rate of flower formation and fruit setting. Spiral ring peeling technology can also be adopted, which can not only prolong the flowering period, but also reduce fruit drop.

4. Tip control and tip protection

If the last autumn shoot is too late and too early, corresponding measures need to be taken. It is easy to grow too early in the last autumn, so it is necessary to spray paclobutrazol timely to restrain its growth, or to use spiral girdling technique to peel the trunk and main branches. If the last autumn shoot is drawn too late, it is necessary to use the combination of organic and inorganic foliar fertilizer to spray the foliar surface 1 or 2 times to promote it to mature as soon as possible. The surplus winter shoots should be removed manually or eliminated with insecticide.

Pruning methods of Guiwei Litchi trees

1. Shaping and pruning of young trees

The shape of the round head of the main branch is often used in the shaping of young trees, which is completed within 2-3 days after planting. Pruning and shaping of young trees were carried out at the same time. Coring, truncation, thinning and wiping buds were used to inhibit shoot growth and promote branches before shoot germination. Should be light rather than heavy, mainly cut off cross branches, over-dense branches, curved branches, weak twigs, and ears of flowers that do not let them bear fruit, so that nutrients can be effectively used to expand the crown, and after pruning, the wound can be smeared with healing film to make the wound heal quickly.

2. Shaping and pruning of result tree

Autumn shoots are the fruiting mother branches of litchi, which are usually cultured only once or twice. The first shoot should be in mid-late July, and the second shoot should be in late September. Reasonable watering and fertilization according to plant needs, spraying new high-fat film to protect fertilizer and soil moisture.

3. Post-harvest pruning

After fruit picking, cut off the fruit stalk, dry branches, withered branches and non-ideal branches damaged during fruit picking, as well as late autumn shoots after the End of Heat; try to retain sunny branches, strong branches and well-growing horizontal branches. After pruning, clean the countryside in time, concentrate on harmless treatment, apply healing film to the wound after pruning, make the wound heal quickly, spray tree protection general, and survive the winter safely.

What is Guiwei litchi?

Guiwei, also known as Guizhi, gets its name because it contains the fragrance of sweet-scented osmanthus. It is one of the best varieties, and it is the best in the suburbs of Guangzhou and Lingshan County in Guangxi. Guiwei has two strains: all red and duck head green. The fruit is round, the shell is light red, thin and brittle; the protuberances of the lobes are small and pointed, and there are deep ring grooves around the top from both sides of the pedicel, both of which are characteristic of cinnamon; soft and full to yellow and white, small stone, sweet taste, ripe in early July.

How to distinguish between Guiwei litchi, Feizixiao and Nuomici

1. Guiwei is relatively small, and even the branches above the fruit are more tied. The nail on the skin is very sharp and the buttocks are sharp. The meat is juicy, crisp, delicious and small.

2. The skin of the concubine's smile is generally green, and the nails on the skin are very dense, the size is relatively large, and the shape looks like strawberries to me. The meat is sweet and sour, and the nucleus is small.

3. Nuomi is bigger than cinnamon, the fruit is shaped like a small tomato, the buttocks are round, and the skin is smooth and there are no nails. The meat is thick and juicy, but not as crisp as cinnamon and small in core.

In addition to the taste of cinnamon, Feizixiao and Nuomici are also good products in litchi. There are many things hanging sheep's head and selling dog meat in the market, so we must keep our eyes open when buying lychees. In addition, planting Guiwei litchi is also a good choice, but we must pay attention to the ways and means of management.
