Efficient breeding technology for Muscadine grapes

Abstract

The invention provides an efficient breeding technology for Muscadine grapes, and belongs to the technical field of agriculture. The efficient breeding technology comprises the following steps: selecting annual branches and tendrils which are mature in tissue and high in lignification degree, and cutting the annual branches into branch sections with the length of 8-12 cm to serve as cuttage branches, wherein each cuttage branch is required to have at least one leaf; reserving about 1cm of branch sections above the leaves, wherein the sections of the ends, away from the leaves, of the cuttage branches are diagonal planes; soaking the parts, below the leaves, of the cuttage branches in rooting treatment liquid; inserting the cuttage branches soaked in the rooting treatment liquid into positioning holes, fixing the cuttage branches on side plates, and ensuring that leaves of the cuttage branches are located outside the side plates; keeping sufficient illumination of the side plates, and supplying water to branches in the side plates and leaves outside the side plates through a first spraying system and a second spraying system; and taking out the cuttage branches with the secondary roots or the tertiary roots growing completely, transplanting the cuttage branches directly or in fixed pots, and carrying out cuttage on new cuttage branches again in the free positioning holes. The efficient breeding technology has the advantages of high survival rate, high efficiency and the like.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and relates to a high-efficiency breeding technology of muscadine grapes. Background technique [0002] Due to environmental differences, the survival rate of muscadine grapes through cuttings is extremely low. Generally, it is carried out by grafting, that is, removing the branches and vines of common grape mother plants that are easy to survive, and grafting muscadine grape branches on the branches of the mother plant. The position of the fracture makes Muscadine grape fruit. This method is not only complicated in process, but also has low reproduction efficiency and needs to rely on the mother plant. The longevity of Muscadine grape is limited by the mother plant. The quality of Kading grapes. [0003] At present, the Muscadine grapes imported into China are generally divided into two subspecies, Geville and Supreme. The survival rate of Geville is higher than that of Supreme, but the o...

[0002] Due to environmental differences, the survival rate of muscadine grapes through cuttings is extremely low. Generally, it is carried out by grafting, that is, removing the branches and vines of common grape mother plants that are easy to survive, and grafting muscadine grape branches on the branches of the mother plant. The position of the fracture makes Muscadine grape fruit. This method is not only complicated in process, but also has low reproduction efficiency and needs to rely on the mother plant. The longevity of Muscadine grape is limited by the mother plant. Cardin grape quality

[0003] At present, the Muscadine grapes imported into China are generally divided into two subspecies, Geville and Supreme. The survival rate of Geville is higher than that of Supreme, but the overall survival rate is extremely lower than that of ordinary grapes. Taking Supreme as an example, It is almost impossible to survive through grape cuttings

[0004] In the prior art, there is also the practice of using perlite as the foundation bed for breeding, but there are shortcomings such as easy rot of the root, insufficient oxygen supply, and inconvenient observation of the rooting situation.
