Dwarfing, close planting and early fruiting culturing method for lychees with shape of chicken beak

Abstract

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.

Description

technical field [0001] The invention relates to a method for cultivating fruit trees, in particular to a method for cultivating chicken-billed lychees with dwarfing, dense planting and early fruiting. Background technique [0002] Jizui lychee belongs to Sapindaceae, and it gets its name because the fruit core is as small as a chicken's mouth. In the state of natural growth, the canopy of Jizui lychee is naturally round, with a height of up to 10m. The tall canopy increases the labor input for flower thinning, fruit thinning, bagging, and harvesting, which reduces production efficiency. The traditional cultivation method of Jizui lychee has the disadvantages of small planting amount per unit, low land utilization rate, low yield, long cycle and late time to market. [0003] Dwarf dense planting refers to a cultivation method that uses biological and cultural methods to make the tree short and the crown compact, make full use of light energy and land resources, and make frui...

AI Technical Summary

Problems solved by technology

In the state of natural growth, the canopy of Jizui lychee has a natural round head shape, with a height of up to 10m. The tall canopy will increase the manual input of flower thinning, fruit thinning, bagging, harvesting, etc., and reduce production efficiency.

The traditional Jizui litchi cultivation method has disadvantages such as small planting amount per unit, low land utilization rate, low yield, long cycle and late time to market.
