Planting method of white orchid

Abstract

The invention discloses a planting method of white orchid. The method comprises the steps that S1, magnolia sirindhorniae is adopted as a rootstock for grafting, and a white orchid grafting plant is grafted upon the rootstock to obtain a white orchid grafted plant; S2, the white orchid grafted plant is planted in selenium enriched laterite two years after grafting is conducted; S3, fertilizers areapplied to the white orchid grafted plant one year after the white orchid grafted plant is planted in the selenium enriched laterite; fertilizer applying is started in early April and late July, thecrown, blades, and flower buds of the white orchid grafted plant are sprayed for three times by adopting a foliar spraying agent, and spraying is conducted every eight days, wherein the foliar spraying agent comprises, by weight, 55-167 parts of foliar fertilizer, 5-10 parts of carbon dioxide sustained-release tablets and 100000 parts of water, and the foliar fertilizer is a rare earth, boron, zinc, copper, ferrous, potassium, calcium and magnesium water soluble foliar fertilizer. The magnolia sirindhorniae has stronger affinity to the white orchid, the grafting survival degree is high, the growing speed of the magnolia sirindhorniae is faster, the magnolia sirindhorniae can provide a large number of nutrients for the white orchid, the magnolia sirindhorniae is adopted and combines with the foliar fertilizer and carbon dioxide in the foliar spraying agent, and the fruit bearing in a large amount of the white orchid is promoted.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a method for planting white orchids. Background technique [0002] Bailan is native to Indonesia and is now widely planted in Southeast Asia. China's Fujian, Guangdong, Guangxi, Yunnan and other provinces and regions are very popular as common street trees. The flowers are white and very fragrant; the flowering period is from April to September and blooms in summer. At present, the main propagation method of Bailan is to use common Huanglan, Huolinan or magnolia magnolia as rootstock grafting; or use high pressure (ring branch) or cutting method. Due to the long-term asexual reproduction, the grafted plants of Bailan lack variation. At the same time, Bailan, a fast-growing tree species, has a short lifespan. After growing to a certain extent, it begins to show aging characteristics, such as centrifugal baldness, withered tops, or damage by parasitic plants. etc. In typhoon-prone sea...

Problems solved by technology

Due to the long-term asexual reproduction, the grafted plants of Bailan lack variation, and at the same time, Bailan, a fast-growing tree species, has a short life span. After growing to a certain extent, it begins to show aging characteristics, such as centrifugal baldness, withered tops, or damage by parasitic plants. etc. During the typhoon-prone season, lodging or folding techniques are prone to occur, which is extremely dangerous
