Embodiment 1

[0024] A kind of greenhouse planting method that improves pitaya sweetness, comprises the following steps:

[0025] A. Shed columns: Select the saline-alkali land, build a greenhouse, and insert a column in the shape of a hexagonal column with a distance of 2-2.5m between two columns in the greenhouse. The height of the column is 2.4 meters, and the part buried in the soil is 0.4 meters. The side length of the top hexagon is 6cm;

[0026] B, planting: in March, plant 3 dragon fruit saplings at 6 corners of each pillar in the mode of two or two intervals;

[0027] C. Growth period: apply the first liquid fertilizer 2000kg per mu every 15-20 days;

[0028] D, flowering and pollination period: after dragon fruit saplings bloom, pour the second liquid fertilizer and spray foliar fertilizer respectively every 2 weeks, the second liquid fertilizer is applied in the mode of circular furrow application, and pour the second liquid with a week Fertilizer, the method of spraying foliar...

Embodiment 2

[0032] On the basis of embodiment 1, the described greenhouse planting method of improving the sweetness of dragon fruit, in February, select the stem node that grows abundantly to cut into the segment that length is 15cm, and engraved at least 3 successively upwards at distance lower part 2cm place. interlaced but non-overlapping semicircular wounds, and smear moss liquid on the wound, insert it in the sand bed after air drying, and wait for the roots to grow to 3-4cm to obtain dragon fruit saplings for planting, and the moss liquid is moss and volume Bamboo vinegar with a fraction of 3% is obtained after grinding with a mass ratio of 1:1.

Embodiment 3

[0034] On the basis of embodiment 1, the described greenhouse planting method of improving pitaya sweetness, after Xie Hua, take the pillar center as the center of a circle at interval pitaya sapling 10cm periphery, dig a wide 20cm, deep 10cm annular ditch Groove, evenly laying a moss layer with a thickness of 3-3.5cm in the groove, the moss layer is washed by fresh moss, dried to a moisture content of less than 20%, and then evenly spread 1-2cm on the moss layer thick water-retaining agent, and then lay a slag heap mixed with sugarcane bagasse and Flammulina velutipes at a ratio of 1:2 on the top of the water-retaining agent to cover until the groove is full.

Abstract

The invention discloses a greenhouse growing method capable of improving sweetness of dragon fruit. The method includes step A of putting up a greenhouse and erecting columns; step B of planting; stepC of a growing period: applying 2000 kg of first liquid fertilizer every 15-20 days per mu; step D of a flowering and pollination period: applying second liquid fertilizer and spraying foliar fertilizer every 2 weeks after flowering of dragon fruit saplings respectively, applying the second liquid fertilizer in a mode of circular furrows, and alternately applying the fertilizer in a mode of applying the second liquid fertilizer in one week and then applying the foliar fertilizer in next week; step E of a fruiting period: performing one-week variable temperature treatment after 15 days after the blossom fall, wherein the variable temperature treatment is concretely as follows: 0 DEG C low-temperature treatment is performed for 1 h from 9:00 AM to 10:00 AM every day, 0 DEG C low-temperaturetreatment is performed for 1 h from 5:00 PM to 6:00 PM every day, and the temperature in the greenhouse is kept at 20-30 DEG C at other periods of time. The dragon fruit greenhouse growing method hasthe advantages of promoting the conversion of pulp glucose into fructose to improve sweetness and sugar uniformity.

Description

technical field [0001] The invention relates to the technical field of dragon fruit planting. More specifically, the present invention relates to a kind of greenhouse cultivation method that improves pitaya sweetness. Background technique [0002] Pitaya is a perennial tropical plant, with one-time investment and multi-year income, and less pests and diseases, thick and easy to grow, low growth cost, and large market demand. Dragon fruit is rich in anthocyanins, plant-based albumin and water-soluble dietary fiber. It has dual effects of beauty and health care, and has increasingly become a well-received fruit in recent years. However, due to the low sweetness of the entrance of dragon fruit and the uneven distribution of sugar, its taste has been affected to a certain extent, and a part of the market has been reduced. Contents of the invention [0003] It is an object of the present invention to solve at least the above-mentioned problems and to provide at least the adva...
