A kind of litchi high-crown happy-shaped tree crown and its cultivation method

Abstract

The invention discloses a litchi high open-center shape crown and a culture method thereof. The distance between branching points of all levels is 60 to 90 centimeters. The branching is uniform in each level. The branches extend to the periphery of the crown. The crown is opened, the top is recessed, the bearing shoots are distributed uniformly and staggeredly arranged in the vertical direction, and the crown is in a open-center shape. Through the litchi pruning method, the obtained high open-center shape crown has the advantages that the branch distribution is reasonable in all levels, the branches are staggeredly arranged in the vertical direction, the crown is open, the shortages of a conventional litchi tree shape are overcome, the crown is lowered, the ventilation and light transmittance are improved, the leaves can better receive sunlight and better accumulate organic substances through photosynthesis, the yield is increased; moreover, the pesticide spraying and fruit picking become convenient; the disease control, pest control, and fruit picking are convenient; the using amount of pesticide is greatly reduced, the pesticide spraying frequency is reduced; the management of alitchi orchard is simplified, and the cost is reduced at the same time. Furthermore, the method is simple and is easy to perform, the incomes of farmers are increased, the application value is high and the method is worthy to popularize and use in a large scale.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation, in particular to a litchi high crown and happy-shaped crown and a cultivation method thereof. Background technique [0002] In recent years, most orchards have carried out closed orchard transformation technology, reducing the planting density and tree crown height through thinning, retraction pruning, etc., and the ventilation and light transmission conditions of the orchard have been improved. Litchi generally adopts a "natural round-headed" tree shape. After picking the fruit, it is short-cut to cultivate the fruiting mother branch of the next year. This will directly cause the fruiting part to move outward year by year, and eventually lead to a tall tree, closed canopy, large branches, The bore is bare and the output is too low. Simultaneously, because the tree body is too high, it is time-consuming and labor-intensive to harvest, and the situation of falling and injuring peop...

Problems solved by technology

At the same time, due to the high tree body, it takes a lot of time and labor to collect fees, and it often happens that people are injured or even killed.
