Method for cutting and seedling raising of vaccinium bracteaturn

Abstract

The invention discloses a method for cutting and seedling raising of vaccinium bracteaturn. Softwood cutting is adopted, wherein branch spikes of wild vaccinium bracteaturn which transplanted for 2 years and grows robustly are cut, and the branch spikes are semi-lignified and similar in maturity and have no diseases and pests; hardwood cutting is adopted, wherein vaccinium bracteaturn branches which grow robustly for 2 years and have no diseases and pests are cut; hardwood cutting is conducted in a cutting seedling bed of a greenhouse, and a small plastic arched shed is set up; softwood cutting is conducted on a full-illumination automatic intermittent spraying seedling bed, and cutting mediums are perlite, peat soil, vermiculite and river sand. Before cutting is conducted, 0.05 potassium permanganate is adopted for disinfection treatment. Rooting agents are IBA, ABT1 rooting powder and NAA. The method for cutting and seedling raising of vaccinium bracteaturn has the advantages that the problem is solved that propagation offspring of vaccinium bracteaturn seeds have big differences, excellent characteristics of parent varieties can be well kept, the operation is simple, the cost is low, the propagation speed is high, and the survival rate is high; a large number of the vaccinium bracteaturn seeds can be quickly obtained, and the method has good popularization value.

Description

technical field [0001] The invention belongs to the field of plant vegetative propagation, and in particular relates to a method for growing seedlings of black rice tree cuttings. Background technique [0002] Vaccinium Bracteatum Thunb., also known as Nanzhu, Dyeshu, etc., is an evergreen shrub or small tree of the Rhododendronaceae Vaccinium genus, widely distributed in southern my country; It is a precious tree species with equal value, and has broad prospects for development and utilization. The black rice tree has a long history of application in our country. Whether it is used as food or medicine, it is unique. Every April, in Jiangnan and other places, there is a custom of picking its leaves to cook black rice; the distribution range of the black rice tree Although it is very wide, due to human factors or the impact of bird pests, there has been a lack of effective protection of resources for a long time. The resources of wild black rice tree have been extremely damag...

The black rice tree has a long history of application in our country. Whether it is used as food or medicine, it is unique. Every April, in Jiangnan and other places, there is a custom of picking its leaves to cook black rice; the distribution range of the black rice tree Although it is very wide, due to human factors or the impact of bird pests, there has been a lack of effective protection of resources for a long time. The resources of wild black rice tree have been extremely damaged, the genetic resources have been seriously lost, and the original wild communities in some areas have even disappeared. Therefore, it is imminent to protect the germplasm resources of wild black rice tree and carry out research on the cultivation of wild black rice tree

[0003] In the past, it was mostly used for seedling breeding, but the actual reproductive seeds need to be refrigerated, and the offspring of seed propagation are highly variable, it is difficult to maintain the excellent characteristics of the variety, and it may not necessarily achieve high yield

In some places, the grafting method is tried. Although the purpose of increasing production can be achieved, the operation is relatively meticulous, requires skilled technology, and requires a lot of manpower and material resources.
