Grafting cultivation method for taxus chinensis

Abstract

The invention relates to a grafting cultivation method for taxus chinensis. The grafting cultivation method is characterized by comprising steps of a, selecting taxus chinensis saplings with required characters, selecting healthy and plumb scion buds on scion branches where leaves are removed and only leaf stalks are remained, transversely cutting the upper side of each scion bud once, cutting the lower sides of the scion buds from bottom to top, connecting each cut opening with the bottom of a corresponding transverse cut opening to form a big-end-up bud slice and taking off the bud slices; b, selecting common taxus chinensis seedlings as rootstocks, transversely cutting each rootstock once, and longitudinally cutting a transverse cut opening of each rootstock downwardly once to form a 'T'-shaped cut opening on the rootstock; c, performing cutting grafting on the buds, in other words, holding each bud sheet by the left hand of an operator, holding a scion bud knife by the right hand of the operator, blocking bast of the rootstocks by the aid of a handle of the scion bud knife, inserting the bud sheets into the open 'T'-shaped cut openings, pressing the leaf stalks of the bud sheets by hands of the operator and tying the leaf stalks of the bud sheets by plastic films; (4), removing branches of the rootstocks straightaway after cutting grafting is performed on the buds, and timely removing sprouts and coppice shoots of the rootstocks. The grafting cultivation method has the advantages of good bud grafting effect, high survival rate and capability of quickly cultivating large quantities of seedlings.

Problems solved by technology

[0004] During the growth and reproduction of yew, some of the traits we need cannot be maintained. For example, in the cold winter, the surface of most of the leaves of yew in the south will turn red and purple, but a few of them remain emerald green; During the season, the southern yew will be covered with red beans, but there are a few special trees that will be covered with yellow fruits
