High-yield cultivation method for custard apple having high trunk, four main branches, and open-center-shaped crown

Abstract

The invention belongs to the technical field of plant cultivation, and discloses a high-yield cultivation method for custard apple having a high trunk, four main branches, and an open-center-shaped crown. The method mainly comprises the following four steps: determining optimal plant spacing, pruning and shaping open-center-shaped crowns, fixing shapes of the open-center-shaped crowns, and controlling and pruning branches. According to the cultivation method, the defects that, in the prior art, the planting density is unreasonable, tree shapes are disordered, branches and tendrils excessively grow, the biomass of vegetative shoots is large, and the proportion of bearing branches is low, are overcome, the number of fruits can be increased by 10-20, the yield of custard apple can be increased by 15-25%, and the labor cost can be reduced by 30%; by means of the custard apple cultivation method, the yield of custard apple can be increased, the cultivation mode is simplified, production operations such as artificial pollination, artificial pruning, bagging, and picking are facilitated, labor consumption is greatly reduced, and good economic benefits can be generated.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and relates to a high-yield cultivation method for a pineapple sakura with a high main trunk and four main branches with a happy-shaped crown. Background technique [0002] Pineapple custard apple is a cross-bred variety of sorrel custard apple and soil variety custard apple used in the Florida Agricultural Experiment Institute. It is an improved species obtained from Taiwan, China and cultivated and domesticated. This variety has unique flavor, excellent quality, and rich nutrition. Favored by consumers, it has developed into the most important cultivated variety in Yunnan, and the cultivated area accounts for more than 80% of the total cultivated area of ​​Yunnan custard apple. Pineapple Sakyamuni has high economic benefits. Generally, after planting and management, it can bear fruit in the second year and produce economic benefits. It can be harvested continuously for more than 20 ye...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to solve the technical defects of tree shape confusion, unreasonable pruning, excessively long branches, more vegetative branches, low proportion of fruiting branches, and inconvenient artificial pollination and fruit picking in the prior art. After the comparative study of the pineapple custard cultivation techniques, a high-yield cultivation method for the pineapple custard tree with a high trunk and four main branches in a happy-shaped crown is proposed, which can simplify the cultivation tree shape, increase the pineapple custard yield, reduce labor costs, and improve economic benefits
