Select the wind to the south, good drainage and irrigation and loose soil to build a garden, suitable for spring planting, plant spacing with 2 × 3 meters. The planting hole should be layered with about 0 3 kg of lime, 30 kg of waste soil fertilizer and 0 5 kg of phosphate fertilizer, composted livestock manure 10-15 kg, calcium, magnesium, phosphate fertilizer 1 0 kg, 0 2 kg of compound fertilizer. After planting, young trees should be fertilized diligently thin Shi, generally every training 1 new shoots fertilizer 2 times, in the new shoots sprouting period and new shoots grow to 40cm each Shi 1 time. Fertilizer to fast-acting nitrogen-based, per plant each time you can apply bran water 2 5-5kg plus urea 0 3%, or urea 50g plus potassium chloride 25g. winter combined with the soil change to increase the application of organic fertilizers once, per plant to apply chicken manure 15kg. winter and spring, per plant to apply lime 0 5kg. fruit tree fertilization around the promotion of the development of strong spring and summer tips, to promote the first fruit and the second fruit of the flower buds differentiation, the fruit and fruit, soil improvement and root development and so on. It is a very good idea to have a good time with the program, and it is a good idea to have a good time.
To pay attention to the increased application of organic fertilizers and lime, nitrogen, phosphorus, potash fertilizer ratio and control in the climatic period, late-acting fertilizers and fast-acting fertilizers with the matching, 6 times a year fertilization.
Pan Lychee taboo drought and fear of water, the rainy season to pay attention to the timely removal of stagnant water, stagnant water easily infected with root rot; such as drought, leaf curl wrinkles, to immediately drenching, fruiting period to pay attention to maintaining a balanced soil moisture, so as to avoid long drought rain caused by cracking and fruit drop. In order to lay the foundation for the early knot yield, AP Fan Lychee should be planned to cultivate the tree shape, young tree pruning is mainly shaping, the use of centering and leaf plucking methods to promote branching, as soon as possible to develop into a dwarf, branching, branching, distribution of evenly rounded head-shaped crown.
In the main trunk height of 40-50 centimeters at the top of the cut, and remove the trunk in the upper leaves 3-4, to promote the main branch 3-4, in the same way in the main branch to promote the main branch to stay 2-3 secondary branch, secondary branch to promote the stay of the third level of branches, too much too weak branch tips in a timely manner to thin out.
The pruning of fruit-bearing trees in the annual harvest of the fruit after pruning once, time about the middle of March, when most of the buds of deciduous branches began to sprout.
Methods are: the periphery of the crown of the large branches retracted pruning to the third or fourth branch, retracted to leave a stake in the head of the length of 20-30 centimeters, and require the head of the stake in the crown was an umbrella-shaped uniform distribution; crown bore diameter of more than 0.5 centimeters of the branches, generally retained 2-4 nodes retracted pruning; the rest of the weak branches, overcrowding, is from the base of the thinning out.
After spring pruning, pay attention to the shoots 5-10 centimeters long in time to thinning, each branch stakes to stay 2-3 evenly distributed new shoots; in the new shoots fruiting branches or nutrient branches up to 30-40 centimeters long in time to plucking, should also be combined with the production period adjustment for summer pruning.
The method of removing the tops and leaves can promote the growth of the new shoots and the formation of flowers, which can be used to regulate the flowering and fruiting period.
In the Zhanjiang area, the AP litchi in April that need to be pollinated, and strive to hang fruit early, in the afternoon at about 5:00 pm, take the other flowers in full bloom, with a soft brush will pollinate on the stigma of the micro-open or semi-open flowers, can significantly increase the amount of fruit, increase the shape of the fruit number of fruits, improve the quality of the fruit. 6 months, need to be cut short to remove the leaves, to promote the flowering of the various phases of the work.
According to the need, arranged in different months to promote flowering, pollination, can achieve the purpose of production period adjustment, so that the fruit production period from September to extend the following year in March.
