Greenhouse cultivation method of dragon fruit

Abstract

The invention discloses a greenhouse cultivation method of dragon fruit. The method includes: building a greenhouse on a land having pH of from 5.5 to 6.5, and providing a first insulation layer; applying organic fertilizer in the greenhouse to make ridges; laying mulching film and pillars; from March to May, after the application of the fertilizers, planting dragon fruit saplings; after the planting of the dragon fruit saplings, setting up arches over the ridges; after the setting-up of the arches, performing irrigating once three to four days for 20 to 35 days on the whole; during planting of the dragon fruit, applying compound fertilizer once a month; clipping off weeds, and covering the roots of the dragon fruit plants with the weeds; after branches of the dragon fruit plants grow to 1.3 to 1.5 m in length, performing cropping; after the dragon fruit is in a fruiting phase, performing artificial pollination and thinning flowers and fruits.

Problems solved by technology

[0003] Pitaya belongs to tropical and subtropical fruits. It likes warmth and humidity. The optimum temperature for growth is 25-35 degrees Celsius. According to data records and practice, dragon fruit stops life activities and even leads to death in an environment of 5 degrees Celsius or below. Therefore, it cannot be widely planted in most areas of our country, and the quality and output of dragon fruit planted in Jiangsu, Zhejiang and Shanghai are not very satisfactory.
