A kind of photoautotrophic air rapid propagation method of Bulgarian damascena rose

Abstract

The invention relates to a quick Rosa Damascena Bulgaria breeding method capable of generating air through photoautotrophy. The method comprises the steps of treatment of a seedling bed, treatment ofin-vitro branches, cutting and management after cutting, wherein according to treatment of the seedling bed, a medium prepared from agricultural waste straw, vermiculite, perlite and ferric oxide hydrate is put into inverted seedling pots, and then the inverted seedling pots are fixed to horizontal tube type or tank type or box type air seeding culture solution cycle supply devices with through holes reserved in the upper portions, all the air seeding culture solution cycle supply devices are erected in a three-dimensional tread shape, water pumps are connected with a water storage tank with aheater and an agent feeding inlet, and an LED cold light source is arranged above the seedling bed; according to management after cutting, after cutting is finished, a seedling solution is circularlyand alternately injected into or drawn out of the air seeding solution cycle supply devices by using the water pumps, and root promoting and sterilization are conducted by using the seedling solutionand dry air. By means of the method, the production time is greatly shortened, the seedling production efficiency is improved, the application range is wide, the method is less affected by environment intervention, the yield per unit area is high, and the seedling quality is high.

Description

technical field [0001] The invention relates to a rapid photoautotrophic air breeding method for Bulgarian Damask roses, and belongs to the technical field of nursery stock propagation. Background technique [0002] Bulgarian Damascus Rose, also known as Turkic Rose, Rosaceae Rosa, native to Syria, was introduced to China in 1981 by the inspection team of the Ministry of Agriculture from Kazanlak Oil Rose, Spice and Medicinal Plant Research Institute. It is a world-recognized precious Rose variety, pure and delicate floral fragrance makes it crowned and fragrant, and becomes the top grade of oil roses. It has important economic and ecological benefits. Due to its complex ecological characteristics and no seeds, grafting cannot maintain the good genes of the female parent, and the layering efficiency Low quality, many seedlings with leggy branches and poor quality, the domestic Damask rose industry is developing slowly. [0003] In order to ensure the purity of the strain an...

Problems solved by technology

[0007] The purpose of the present invention is to overcome the existing technologies such as full-illumination micro-mist, suspension seedling cultivation, etc., which occupy a large area and have poor seedling-raising benefits, are difficult to avoid soil-borne and water-borne diseases, substrate hardening, rot caused by long-term immersion, and poor stress resistance. It is difficult to manage the humidity of the substrate after transplanting and cannot meet the needs of isolated branches in a timely manner. It provides a substrate prepared from agricultural waste straw, which uses the plant's own regulation and capillary action to absorb on demand, and uses LED cold light sources to supplement the spectral energy required by plants. The photoautotrophic air rapid breeding method that uses the stepped three-dimensional seedling rack to increase the output per unit area can greatly reduce the cost and shorten the time, reduce the time and space constraints brought by the light conditions, and improve the rooting rate and survival rate of the isolated branches;
