Embodiment 1

[0031] In Dongguan City, Guangdong Province, a pitaya farm with an area of ​​40 mu adopted a cultivation method to induce off-season flowering of pitaya in 2014-2015. The specific steps are as follows:

[0032] 1. Soil treatment:

[0033] (1) After the saplings are planted, in July, October and March of the following year, a single plant is applied with a mixture of chicken manure, mushroom dregs, rice straw powder (mass ratio 2:1:1) and 0.3% (accounting for bio-organic Fertilizer mass percent example) Bacillus subtilis (20 billion / gram of effective viable bacteria) mixed fermentation bio-organic fertilizer 5kg, the surface covers 1-2cm shallow soil.

[0034] (2) Cover the area within 50cm of the tree tray with straw, and cover the drainage ditch between the rows with agricultural grass-proof cloth.

[0035] 2. Fertilization: Young trees (1-2 years) apply compound fertilizer to a single plant every month (N:P 2 o 5 :K 2 O=15:8:10; mass ratio) 25-40g; Mature trees (3 years ...

Embodiment 2

[0044] Nanning City, Guangxi Province, with an area of ​​20 mu. In 2014-2015, a cultivation method for inducing dragon fruit to flower out of season was adopted. The specific steps are as follows:

[0045] 1. Soil treatment:

[0046] (1) After the saplings are planted, in July, October and March of the following year, a single plant is applied with a mixture of pigeon manure, mushroom dregs, rice straw powder (mass ratio 2:2:1) and 0.2% (accounting for bio-organic Fertilizer mass percentage example) 4kg of bio-organic fertilizer formed by mixed fermentation of Bacillus subtilis, and then the surface is covered with a layer of 1-2cm shallow soil.

[0047] (2) Cover rice husk and mushroom slag (mass ratio: 1:1) within 70 cm of the tree tray, and cover agricultural grass-proof ground cloth with drainage ditches between rows.

[0048] 2. Fertilization: mature trees (4 years old) are in the vegetative growth period, and the first compound fertilizer (N:P) is applied to each plant...

Embodiment 3

[0059] Yuanmou County, Yunnan Province, with an area of ​​20 mu. In 2015, a cultivation method for inducing dragon fruit to flower out of season was adopted. The specific steps are as follows:

[0060] 1. Soil treatment:

[0061] (1) After the saplings are planted, in July, October and March of the next year, a single plant is applied with a mixture of chicken manure, cow dung, mushroom slag, rice straw powder (mass ratio: 1.5:1.5:1:1) and 0.25 % (accounting for the mass percentage of biological organic fertilizer) 4.5kg of biological organic fertilizer formed by the mixed fermentation of Bacillus subtilis, and then cover the surface with a layer of shallow soil of about 2cm.

[0062] (2) Mushroom slag shall be covered within 60cm of the tree tray, and the drainage ditch between rows shall be covered with agricultural grass-proof ground cloth.

[0063] 2. Fertilization: mature trees (3 years old) are in the vegetative growth period, and the first compound fertilizer (N:P) is...

Abstract

The invention discloses a cultivation method for inducing pitaya out-of-season flower formation. The method includes the steps that after saplings are planted, 4-5 kg of organic fertilizer is applied to each sapling in July and October every year and March of the next year, and 40-50 g of first compound fertilizer is applied to each of mature association trees of 3 years old or older every month in the vegetative period; 50-60 g of second compound fertilizer is applied to each tree every month in the flowering and fruit bearing phase; light replenishing is carried out at 20:00 to 22:00 from the last ten days of September to the last ten days of October, and the light replenishing duration is 2 hours; light replenishing is started at 20:00 on November, and the light replenishing duration is 3 hours or longer; light replenishing is started from 19:00 on December, and the duration is 5 hours or longer. Irrigation and pruning are carried out in seasons, different light replenishing means are adopted in autumn and winter to achieve the purpose that the flowering phase of pitaya is prolonged to the last ten days of December, fresh fruits can appear on the market from the last ten days of December to March of the next year, the moment is just the slack season of the fresh fruits, and the price can be 3-5 times or above that of the full fruiting phase.

Description

technical field [0001] The invention relates to pitaya cultivation, in particular to a cultivation method for inducing off-season flowering of pitaya, belonging to the technical field of fruit tree cultivation. Background technique [0002] Pitaya originated in Central and South America and belongs to tropical and subtropical fruit trees. In recent years, due to the good planting efficiency, it has risen rapidly in mainland China. It is mainly distributed in Guangdong, Guangxi, Fujian, Hainan, Yunnan and Guizhou. There are also many areas in the north that use greenhouses for cultivation. [0003] Tropical fruit trees have the characteristic of blooming multiple times a year. The key to production period regulation is to synchronize the growth, maturity, flower bud differentiation, and flowering and fruiting of multiple batches of shoots, especially to inhibit vegetative growth in time to promote flower bud differentiation. Different types of fruit trees have different flow...
