Method for improving butterfly orchid seed germination rate and shortening germinating time

Abstract

The invention belongs to the technical field of flower seed treatment, and particularly discloses a method for improving butterfly orchid seed germination rate and shortening germinating time. The method specifically comprises the following steps: (1) carrying out freezing treatment on butterfly orchid seeds, taking out the treated butterfly orchid seeds, carrying out stir-frying at constant temperature, taking out the butterfly orchid seeds after stir-frying, soaking the butterfly orchid seeds into a ferric nitrate solution, and taking out a filter liquor; (2) carrying out magnetizing treatment, soaking the seeds in seed soaking solution, fishing out the seeds from the filter liquor, and carrying out microwave drying, wherein the seed soaking solution is prepared from the following raw materials: erythritol, polygahatous polysaccharides, lycium barbarum polysaccharide, robiniae, Chinese toon sprouts, purslane, copper chloride and water. Rapid germination of butterfly orchid seeds is effectively promoted, so that the germination rate reaches 88% or more, the butterfly orchid emergence rate and seedling survival rate are effectively improved, the abloom rate of butterfly orchid seedpropagation can also be improved effectively, the flowering period is prolonged, the occurrence of diseases in the growth period of butterfly orchid can be reduced effectively, the cold resistance isstrengthened, vigorous growth at low temperature can also be realized, and the method is easy to manage.

Description

technical field [0001] The invention belongs to the technical field of flower seed treatment, in particular to a method for improving the germination rate of phalaenopsis seeds and shortening the germination time. Background technique [0002] Phalaenopsis belongs to the genus Phalaenopsis of the family Orchidaceae, native to subtropical rainforest areas, and is an epiphytic orchid. Phalaenopsis white thick aerial roots are exposed around the leaves. In addition to absorbing nutrients in the air, it also has growth and photosynthesis. In the new spring, the Phalaenopsis plants pull out long flower stalks from the leaf axils, and bloom flowers shaped like flying butterflies. They are deeply favored by flower fans and are known as the "Queen of the Orchids"; Phalaenopsis generally require specific Seeds can only be produced by insect pollination. Since many Phalaenopsis are artificially cultivated varieties, there are no corresponding insects that can pollinate in nature. Only...

[0002] Phalaenopsis belongs to the genus Phalaenopsis of Orchidaceae. It is native to subtropical rainforest area. It is an epiphytic orchid. Phalaenopsis white and thick aerial roots are exposed around the leaves. In addition to absorbing nutrients in the air, it also has growth and photosynthesis. In the Spring Festival, the Phalaenopsis plants pull out long flower stalks from the leaf axils, and bloom flowers in the shape of flying butterflies. Seeds can only be produced by insect pollination. Since many Phalaenopsis are artificially cultivated varieties, there are no corresponding insects that can pollinate in nature. Only artificial pollination can be used for family breeding. However, it is particularly difficult for Phalaenopsis seeds to germinate. The seeds of Phalaenopsis and The seeds of other orchids have no endosperm, and they cannot germinate by their own savings, so the reproduction of Phalaenopsis seeds is greatly inhibited; although there are methods for improving the germination rate of butterfly seeds in the current prior art, it does not Did not obtain desired effect, so be badly in need of inventing a kind of method that improves the germination rate of Phalaenopsis seed
