The invention provides a
dwarfing, close planting and early fruiting culturing method for lychees with the shape of a chicken
beak. The culturing method comprises the following steps:
grafting, namely selecting Sapindaceae
dwarfing rootstocks and adopting scion
grafting method to perform cleft
grafting; field setting, namely arranging the planting holes in rectangle or staggered different line manner;
nutrient and water management, namely primarily adopting the method of frequent and low-amount fertilization, applying phytocide, and utilizing a mulching film; shaping and trimming, namely controlling each tree crown to be an expanding heart shape with two
layers and seven leader branches through
trunk fixing,
bud carving and
branch trimming, and controlling tree height through
cutting the
trunk in a
ringing manner, trimming in a retractable manner in the winter, and promoting growth of new buds through
cutting main branches and side branches in a
ringing manner;
drug spraying, namely applying
growth regulation substances;
insect disease prevention. The culturing method adopts the
dwarfing rootstocks which is in the same family as the lychees with the shape of the chicken
beak to complete grafting; the tree height and tree crown shape are controlled through trimming; the seedlings of lychees with the shape of the chicken
beak is shortened through applying drugs; the
fertility is reserved through utilizing the mulching film; the
sunlight utilization ratio is increased, and early fruiting and high yield of the lychees with the shape of the chicken beak are obtained; the culturing method provided by the invention is quick in bringing production, early in fruiting, high in yield, and good in fruit quality.
