Problems solved by technology

The asexual reproduction coefficient of Rhododendron orchid is very low and the cycle is long; due to the low natural pollination rate of sexual reproduction, the harvested capsules are very few, and the seeds can hardly germinate under natural conditions, making it difficult to achieve large-scale production

Abstract

The invention relates to an artificial pollination method of cremastra appendiculata. The method comprises the following steps: (1) choosing the cremastra appendiculata with robust scape, no pest anddisease damage and 15 to 20 flowers on each plant as pollination plants; (2) performing flower thinning treatment on the plants before pollination and keeping 10 to 15 flowers on each scape; (3) performing different-plant different-flower pollination on the flowers which have been thinned and are in a bloom period on the morning of sunny days. The method disclosed by the invention obviously improves the maturing rate and the seed germination rate of cremastra appendiculata and is an effective path to achieve rapid propagation of the cremastra appendiculata and solve resource regeneration of the cremastra appendiculata.

Description

technical field [0001] The invention relates to a method for artificial pollination of rhododendron orchids, in particular to a method for artificial pollination of rhododendron orchids with relatively high seed setting rate and seed germination rate. technical background [0002] Rhododendron orchid [Cremastra appendiculata (D.Don) Makino] is a perennial rare medicinal herb of Orchidaceae (Orchidaceae) Rhododendron orchid genus (Cremastra). Its anti-tumor effects have attracted widespread attention. Due to the high medicinal value of Rhododendron orchid, people excavate it in large quantities, coupled with the limitation of the species' own reproduction mechanism and the destruction of the growth environment, its wild resources are reduced and it is on the verge of extinction. Rhododendron orchids are often inclined to one side of the inflorescence, drooping, narrow bell-shaped, stamens and pistils are fused into stamen columns, and pollen is blocky. Due to the special str...
