Detailed Explanation of Management Techniques During the Lychee Fruiting Period
Lychee is a common summer fruit with many varieties, including early-maturing, mid-maturing and late-maturing types with different growth periods, so that the supply of lychees on the market can last longer. Lychees are deeply loved by people, and being a seasonal fruit, their economic benefits are much better than other fruits. For greater returns, high yield is needed, and for high yield, management during the fruiting period is very important. Let's learn together how to do it!
1. Reasonable Fertilization
Apply pre-flowering fertilizer in December of the first year, with nitrogen fertilizer accounting for 30% of the annual total, phosphorus fertilizer accounting for 30% of the annual total, and potassium fertilizer accounting for 40% of the annual total. This can prevent spring decline. Apply fruit-strengthening fertilizer 15 days after the flowers fade, mainly potassium, with potassium fertilizer accounting for 50% of the annual total, nitrogen fertilizer accounting for 30% of the annual total, and phosphorus fertilizer accounting for 20% of the annual total. This mainly supplements nutrients and prevents physiological fruit drop. Apply post-harvest fertilizer one week before picking the fruit, mainly to maintain tree vigor and cultivate autumn shoots. Nitrogen fertilizer accounts for 50% of the annual total, phosphorus fertilizer 30%, and potassium fertilizer 20%.
2. Reasonable Irrigation
In the late stage of flower bud differentiation, irrigate to prevent dryness and promote rapid flower bud differentiation. If it rains during the flowering period, provide shelter from the rain, and after the rain, clear the drainage ditches to drain water. Water less during the flowering period, as flowers are prone to dropping. In drought, water promptly in the evening. During the fruiting period, sufficient water is needed, watering once every two weeks. When ripening, to prevent fruit cracking, water less.
3. Intertillage and Mounding
Loosen the soil twice. The first time, around fruit harvest, to a depth of 10 cm. After the autumn shoots mature, cultivate again to a depth of 15 cm. This mainly cuts a small number of roots to inhibit the sprouting of winter shoots. Finally, before flowering, to a depth of 10 cm. Loosen the soil layer to promote root growth. After clearing the orchard, mound soil to 5 cm to keep warm and protect the roots.
4. Plant Adjustment
Cultivate fruiting branches, generally with a thickness of more than 0.4 cm; thin and weak branches should continue to be cultivated or thinned out. The length is about 20 cm. Water sprouts should be pruned off and not used as fruiting branches. Old and weak branches are not suitable for fruiting and should be renewed and replaced during the summer vigorous growth period. Branches with little remaining leaf growth and light leaf color should be thinned out. For dense branches, keep the strong ones; pendant branches cannot bear fruit and should be pruned off.
5. Artificial Pollination
During the flowering period, keep bees in the orchard to let them pollinate indirectly. Or collect pollen and pollinate with a brush on sunny days, or use a duster to spray pollen. Using a brush is precise but laborious, while dusting is slightly less precise but convenient. Boric acid can be added to the pollen solution to help preserve flowers. If it rains after pollination, re-spray.
