A kind of cultivation method that can make passion fruit mature in batches and high yield

Abstract

The invention provides a cultivation method capable of enabling passion fruit to mature batch by batch and realize high yield. The cultivation method is characterized by including that a canopy frame is composed of two rows of oppositely-arranged uprights, cross rods on the uprights, steel wire layers on the cross rods, nylon nets and plastic thin films, the nylon nets and the plastic thin films are arranged on the steel wire layers, the uprights and the cross rods form the canopy frame in the shape of a Chinese character 'men', and the cross rods include upper-layer cross rods and lower-layer cross rods. Shaping and pruning refer to topping when a main vine grows to be higher than 9-12cm of the lower-layer cross rods of the canopy frame, enabling the main vine to be branched out side vines and selecting and reserving 5-6 branches as first-stage side vines, topping for the second time when the first-stage side vines grow to be 45-55cm, and adopting the method for the first-stage side vines to the side vines from second stage to fourth stage. Fertilizer and water management refers to adopting water-fertilizer drop-irrigation-type fertilizing. The cultivation method is high in yield, capable of enabling passion fruit trees to basically realize unified flowering, unified maturing and unified picking and harvesting, and beneficial to large-scale production.

Description

technical field [0001] The invention relates to a planting method of fruit trees, in particular to a cultivation method capable of making passion fruit mature in batches with high yield. Background technique [0002] Passion fruit is a tropical vine evergreen fruit tree. The growth of branches and vines has the characteristics of continuous growth. The life span is as long as eight to ten years. The different flowering seasons cause the passion fruit to have non-uniform flowering period, non-uniform fruiting period, and non-uniform harvest period, which is not conducive to large-scale production, and the yield is low, and the fruit is sour. In order to improve the yield and quality of passion fruit, Zhang Lizhu published a summary of "Passion Fruit High Yield Technology" in Volume 22, Issue 7 of China Fruit Industry Information, and mainly disclosed the following content: Tree management: (1) Introducing vines to shelves: After the seedlings resume growth after planti...

Problems solved by technology

This method can keep flowers and fruits in the orchard, but it cannot form batch results, which is not conducive to large-scale production. In addition, artificial spraying, spreading, and foliar spraying use a large amount of fertilizer, and the effect is not good
