Breeding method for further optimizing wild improved variety of dendrobium huoshanense

Abstract

The invention discloses a breeding method for further optimizing a wild improved variety of dendrobium huoshanense. The method comprises steps: (1) building a base; (2) planting plants; (3) managing after planting; (4) performing artificial pollination; (5) performing management after pollination; (6) and harvesting fruits. In the method, artificial pollination is performed by mutual pollination between each two clusters of plants, so as to maintain good hereditary stability, and improve stress resistance and growing speed of the plants. Arranged umbrella-type protective screens further ensure activities of insects would not conduct pollens among different plants in the same cluster and among plants in different clusters or damage pollination. Applied organic fertilizer is prepared according to natural growth laws of dendrobium, and the organic fertilizer is rich in nutrient, and is natural organic matter, and would not cause any damage to the dendrobium or cause drug residue, thereby ensuring quality of the dendrobium and security. Germination rate of seeds bred by the method is high, seedlings are in order and stable in property, and are good in stress resistance, and vigorous in growth vigor.

Description

technical field [0001] The invention belongs to the field of planting, and in particular relates to a further optimized breeding method for wild fine varieties of Dendrobium huoshanense. Background technique [0002] Dendrobium huoshanense (scientific name: DendrobiumhuoshanenseC.Z.TangetS.J.Cheng), commonly known as rice dendrobium, is a herbaceous plant of the genus Dendrobium orchidaceae. Stem erect, fleshy, unbranched, with 3-7 nodes, light yellow-green, sometimes with lavender spots, light yellow when dry. Leaves leathery, 2-3 alternate on the upper part of the stem, obliquely protruding, tongue-shaped oblong. Racemes 1-3, issued from the upper part of the old stems with fallen leaves, with 1-2 flowers; flowers light yellow-green, spreading; petals ovate-oblong, apex obtuse, with 5 veins; lips nearly Rhombus, approximately equal in length and width. China National Geographical Indication Products. It is mainly produced in Huoshan County, Anhui Province in the Dabie ...

Problems solved by technology

At present, the benefits of cross-pollination have also been reported, but the inventors have found in a large number of experiments that the seedlings still have unevenness and large performance differences, which cannot meet the needs of optimizing provenance.
