Mexicl layering the lychee. First, it possesses all the advantages of vegetative propagation methods, such as maintenance of the wanted traits of the to-be-propagated varieties, and early bearing due to no juvenile phase is present as scions are taken from plants in adult phase.

Litchis are particularly suited to this method of propagation, since they have stiff branches, which do not bend easily and are capable to produce several shoots each year Menzel, Handbook of fruit science and technology: Girdling or cinturing the stem before taking cuttings, block the downward translocation of carbohydrates, hormones, and other possible root promoting factors and can result in an increase in root initiation.
The cuttings should have at least three nodes lengthwise so that one can be in the rooting medium and the two can give rise to shoot growth. In terms of sanitary prevention the nursery man must watch the quality of the equipment used for maintenance works the shears must be well sharpened and regularly washed with water and chlorine, for chinensos.

Criteria for selection of rootstocks Rootstocks contributes to the root system and exert strong effect on the vigor of the propagated litchi chinensi. As many diseases and the nematodes are spread by irrigation water, the water used must be treated with chemical products or come from a clean source a drill for instance.
According to folklorea lychee tree that is not producing much fruit can be girdledleading to more fruit production.
Semi-hardwood and softwood cuttings are also rooted easily under favorable rooting environment and with auxins. Wikimedia Commons has media related to Litchi chinensis.
Acta HorticulturaeThe Hague, v. Handbook of environmental physiology of fruit crops. Criteria for selection of budwoods are based on several factors that may influence grafting success: It is essential that during this period the rooting medium be kept moist as the root primordial are extremely succulent and should be favoured with an adequate supply of water in the early development. The incorporation of soil from old plantations to the substrate has been recommended because of the potential benefit of soil mycorrhizae present Higgins, ; Kadman and Slor, but soil must be free chineensis pests and diseases and the required disinfection will kill fhinensis arbuscular mycorrhiza fungi.

Bengal prior to flower initiation in May, showed per cent rooting Paxton et al. Mother plants should be nourished with recommended doses of nutrition to encourage more vigorous shoots. This method is most commonly used mdxico propagating litchi as it needs much less skill and force to operate. A note on the propagation of litchi.
Propagation of the litchi. After examining the main morphological and developmental characteristics of the plant and the description of the structures and materials, including types of substrate required for the propagation of this species, the different methods for its propagation are discussed.
Air layer operation Before air layer operation lychee tree must be well hydrated to facilitate the bark removal. It is also desirable that greenhouses have an adequate ventilation system and that be provided with cooling system and nebulization systems to avoid extremes of high temperature and low humidity. These are eliminated by using either a constant or an intermittent mist over the propagating bed. However, up to now no universal dwarfing rootstock has been found in litchi.
Those grown from seeds either for direct planting or as rootstocks for further grafting possess a strong tap-root with a well-distributed secondary and tertiary root system.

The fruit can be dried with the rind intact, at which point the flesh shrinks and darkens. Budwoods are cut into cm sticks with buds and a sharp and clean downward basipetal angled cut is made through the internodes on the budstick. Although it is advisable to establish littchi fertilization in the nursery according with a chemical analysis of the substrate, slow release fertilizers at the dosage of g of NPK or similar can be recommended. These operations are not necessary in the case that the grafting process has been done in seedlings prepared on bags at the nursery, since almost no disturbance of the root system will occur during field transplant.
First, the grafted seedlings to be released should be true-to-type with all traits identical to their source cultivar.
