Embodiment 1

[0019] Embodiment one: a kind of southern yew grafting cultivation method, comprises the following steps:

[0020] (1) Preparation of grafting tools: Prepare budding knives, pruning shears and plastic film; budding knives must be sharp, otherwise it will affect the operation and slow down the speed, and due to uneven cutting, the contact between the budding and the rootstock wound will not be good; plastic The film adopts polyvinyl chloride film, the width is 1cm, and the length is 20cm;

[0021] (2) During the grafting period, choose rootstock buds that germinate, expand, and have not yet germinated; at this time, the temperature rises, the sap flows, the roots absorb water, and nutrients are transported upwards, but no nutrients are lost due to germination. Grafting at this time is conducive to survival, so Grafting is generally selected between March and April in spring;

[0022] (3) Specific operation method of grafting:

[0023] a. Take buds: choose robust southern yew ...

Embodiment 2

[0027] Embodiment two: a kind of southern yew grafting cultivation method, comprises the following steps:

[0028] (1) Preparation of grafting tools: Prepare budding knives, pruning shears and plastic film; budding knives must be sharp, otherwise it will affect the operation and slow down the speed, and due to uneven cutting, the contact between the budding and the rootstock wound will not be good; plastic The film is made of polyvinyl chloride film with a width of 1.5cm and a length of 30cm;

[0029] (2) During the grafting period, choose rootstock buds that germinate, expand, and have not yet germinated; at this time, the temperature rises, the sap flows, the roots absorb water, and nutrients are transported upwards, but no nutrients are lost due to germination. Grafting at this time is conducive to survival, so Grafting is generally selected between March and April in spring;

[0030] (3) Specific operation method of grafting:

Embodiment 3

[0035] Embodiment three: a kind of southern yew grafting cultivation method, comprises the following steps:

[0036] (1) Preparation of grafting tools: Prepare budding knives, pruning shears and plastic film; budding knives must be sharp, otherwise it will affect the operation and slow down the speed, and due to uneven cutting, the contact between the budding and the rootstock wound will not be good; plastic The film is made of polyvinyl chloride film with a width of 1.2cm and a length of 25cm;

[0037] (2) During the grafting period, choose rootstock buds that germinate, expand, and have not yet germinated; at this time, the temperature rises, the sap flows, the roots absorb water, and nutrients are transported upwards, but no nutrients are lost due to germination. Grafting at this time is conducive to survival, so Grafting is generally selected between March and April in spring;

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.

Description

technical field [0001] The invention relates to a method for grafting and cultivating southern yew, belonging to the technical field of tree planting. Background technique [0002] Yew is an evergreen tree, the branchlets turn yellow-green or light reddish-brown in autumn, the leaves are strip-shaped, dioecious, the seeds are flat and round, the seeds are used to extract oil, and can also be used as medicine; it is a shallow-rooted plant, its main root is not obvious, Well-developed lateral roots, 30m high, 1m trunk diameter; leaves spirally alternate, base twisted into two rows, strips slightly curved, 1-2.5cm long, 2-2.5mm wide, leaf margins slightly recurved, leaf tips acuminate, There are 2 wide yellow-green or gray-green stomatal belts on the back of the leaves, densely growing small bumps on the midrib, very narrow green belt on the leaf edge, dioecious, male cones are solitary in leaf axils, and ovules of female cones are solitary in flowers The top of the lateral sh...
