Permeable shelf-shaped cultivation method for passion fruit

Abstract

The invention discloses a permeable shelf-shaped cultivation method for passion fruits, which comprises the following steps: (1) a permeable shelf-shaped fruit shed is built; (2) the passion fruit seedlings are fixedly planted below the longitudinal beams along the length direction of the longitudinal beams, the planting row spacing is at least 1.3 meters, and the planting spacing is at least 4 meters; (3) before the main trunk of the passion fruits is arranged on the shed frame, the lateral buds are all removed, and only the main buds are reserved for growth; when the main trunk reaches the length of the upper frame, the upper frame is wound on the longitudinal beams, so that the main trunk grows into a main vine along the wiring of the longitudinal beams; (4) combing and pulling down thefruiting branches and vines grown on the main vine to make the fruiting branches naturally droop, and then pruning the fruiting branches according to the growth of the passion fruits and the formation of flower buds to induce the formation of the fruiting branches; (5) pruning the fruiting branches and vines with picked fruits and reduced flower forming capacity; (6) continuously repeating the steps (4) and (5) in the process of planting the passion fruits so as to continuously induce the formation of the new fruiting branches and vines and increase the yield. According to the permeable shelf-shaped cultivation method, the permeability of fruit shed is improved, the utilization rate of light energy is improved, and the yield and quality of the passion fruits are improved.

Description

technical field [0001] The invention relates to a kind of fruit tree cultivation, in particular to a method for cultivating passion fruit in a transparent frame form. Background technique [0002] Passion fruit, also known as egg fruit and love fruit, scientific name: Passiflora, Latin name: Passiflora edulisSims., is a herbaceous vine of Passiflora genus Passiflora. Originally produced in the Antilles, it was widely planted in tropical and subtropical regions, and then introduced to China. It is mainly cultivated in Guangdong, Guangxi, Hainan, Fujian, Yunnan, Taiwan and other regions. In the early days of introduction, although passion fruit has a strong fruity aroma, its juice is very sour and has a bad taste, which is not acceptable to the public, so it has not been planted on a large scale. After the variety was improved, the moderately sweet and sour fruit juice was favored by the public, thus forming a large-scale plantation in the past 10 years and bringing considera...

AI Technical Summary

Problems solved by technology

[0004] 1. The plane of the leaf curtain layer receives light, the light energy utilization rate is low, the fruit yield is low, and the quality is poor

[0005] 2. Passion fruit branches and tendrils grow freely, disorganized, intertwined with each other up and down, left and right, and the upper and lower branches and tendrils overlap seriously, causing adverse effects:

[0006] 2.1 The upper leaves cover the lower branches and leaves, and the lower branches are weakened and lose the ability to bear fruit or even die

The fruit setting period cannot be pruned reasonably, and ordinary workers have no way to start. However, if the passion fruit branches are not properly renewed and pruned, it will greatly affect the subsequent fruit setting, affect the yield and quality

[0007] 2.2 Due to the overlapping and winding of branches and tendrils, it is chaotic and disorderly. Even if a skilled worker prunes, it is difficult to judge where to start pruning. The trend of social development is that the labor force is becoming more and more scarce

Although some fruits can still hang on the top branches and tendrils, the amount of fruit hanging will be reduced due to the impact of permeability, and it will be difficult to harvest some fruits, which will affect the labor efficiency of harvesting
