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 from pests and diseases and the required disinfection will kill the arbuscular mycorrhiza fungi.
The litchi botany production and uses. They are also very slow to bear, usually 10 years or more Menzel, and because of this are not appropriate for commercial plantings and are only used as rootstocks for grafting and for research and breeding purposes.
Plant production at the nursery The litchi plants must be planted in an appropriate bag, as it may remain in this container for many months before its transplantation onto the orchard.
The outside of the fruit is pink-red, roughly textured and inedible, covering sweet flesh eaten in many different dessert dishes.
In this method the mother plant can be used year after year. Irrigation facilities should allow frequent water application to the pots which permit to keep substrata humidity at the right level avoiding flooding of it. As a result, the scion cultivar is multiplied. On single branch system, the crown is removed 60 to 80 cm above the rooted ball and potted.
Retrieved 5 April After grafting, the conjunction and the budstick must be well protected with soft polyethylene film or parafilm. To reach this size, the scion should have undergone at least two cycles of flush growth.
China Agriculture Press, Archived from the original PDF on The raw sphagnum moss should be washed with tap water to remove excess of salts and kept in basket filled with water for hydration before use and the excess of water removed just by hand compression. Criteria for selection of aerial part scion and plant Scion materials are taken as budwoods from source trees of the to-be-propagated cultivar. Second, the grafted seedlings should not be with an incompatible joint reflected by tissue swelling above the joint.
Handbook of environmental physiology of fruit crops. Lychee young roots in the air layer are very sensitive to chemical fertilizers and raw manure or compost; so, add if necessary with caution to avoid root burning.
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 instance. Effect of growth regulators and boric acid on lychee cuttings. They are also grown as an ornamental tree as well as for their fruit.
The scion used in this method can be a short budstick with only one bud.
Preliminary study on different rootstock-scion combinations in ‘Shuangjianyuhebao’ litchi. To reduce ljtchi due to transpiration, the seedlings should be pruned to a height around 50cm removing most of the leaves leaving 3 chniensis 4 compound leaves each with 2 small leaves. Science and Culturev. Florida’s Best Fruiting Plants: Although it is advisable to establish the fertilization in the nursery according with a chemical analysis of the substrate, slow release fertilizers at the dosage of g of NPK chinnesis similar can be recommended.
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. Shoots in full sun rooted better When the young plants had reached a height of 15cm they should be transplanted into individual bags.
Criteria for selection of rootstocks Rootstocks contributes to the root system and exert strong effect on the vigor of the propagated litchi trees. This is best done by providing bottom heat medico thermostatically controlled electric heating cables or hot water pipes under the rooting frames.
The mixture that is obtained must ensure a good draining of the irrigation water, a good growth of the roots and so on. The same NPK fertilization can be used in the case of fertigation but always taking care of not increasing much the electrical conductivity. Indian Journal HorticultureDehra Dun, v. It is also desirable that greenhouses have an adequate ventilation system mexiico that be provided with cooling system and nebulization chinensiss to avoid extremes of high temperature and low humidity.
Methods of grafting Various methods of grafting are available. Revista Brasileira de Fruticultura, Jaboticabal, v. Treatment with indole butyric acid IBA produces a fibrous root system both at lower and higher concentrations. A source of clean water must be used for watering the plants.

The propagation site must have on its proximity an independent place for storage of propagation substrata and preparation of mixtures close to the propagation general structure. Therefore, after taken from the fruit, they should be placed in wetted sand as soon as possible to force germination.
The nursery must be provided with adequate installations for irrigation and fertilization the more automatically regulated as possible according to technical and hand labour availability and cost. The same cultivar grown in different climates can produce very different fruit. Time required from potting to transplanting to the field depend also on type of nursery plant raised. Further, making the cut immediately below a node results lihchi a greater concentration of roots at the more basal parts of the cuttings.
When the stem diameter at ground height grows to around 6 cm, they are ready for grafting.
A tall evergreen tree, the lychee bears small fleshy fruits. Therefore, a large number of scion pieces can be collected from one mature tree. If the tree must remain in the bag for a long period, the size of containers must be bigger: The lychee bears fleshy fruits that mature in 80— days depending on climate, location, and cultivar.
Lychee – Wikipedia
Cuttings are usually cm in length and mm in diameter. Chemical fertilization can be applied straight to the pot but chemical fertilizers should be placed at an appropriate separation from the plant stems. Unless in greenhouses, avoid grafting operation in times when heavy rain or abrupt temperature fluctuations may occur within 5 days after grafting.
A good nursery plant has a straight stem with branches future framework branches that branch horizontally at about mm high.
In case of air-layering, the branches to be girdled and later cut off as layers are mostly medium-size branches 2 to 3 cm in diameterwhich are much fewer than smaller shoots for grafting budwood in a source tree.
