Abstract
The invention discloses an acer palmatum twig grafting propagation method, which belongs to a plant vegetative propagation method. The method comprises the following steps of: (1) determining grafting time; (2) preparing rootstock; (3) pinching; (4) cutting scion; (5) cutting the rootstock; (6) joining; and (7) managing grafted seedlings. According to the method, the superior ornamental feature of the acer palmatum can be kept; the rootstock and the scion on which twigs of the acer palmatum are grafted are crisp and tender, and operation such as rootstock cutting and scion cutting is quick, easy and convenient; and thus, the efficiency is increased by over 30 percent compared with hardwood grafting.
Description
Technical field
The present invention relates to a kind of woody plant asexual reproduction method, specifically relate to a kind of Acer palmatum grafting of tender branch propagation method.
Background technology
Acer palmatum (Acer palmatum) is Aceraceae (Aceraceae) Acer (Acer) deciduous tree or dungarunga, its tree performance is graceful, leaf, leaf look peculiar, view seeds in important township, world-renowned foliage tree Zhong，Ye Shi China Yangtze river basin.In order to keep the good characteristic of Acer palmatum gardening fancy breed, generally with asexual reproduction methods such as graftings, breed propagation by grafiting
In take the scion grafting of season in spring as main, because affected by arid in spring, cold in the late spring etc., graft survival rate is only 70% left and right: grafting of tender branch is to carry out in the season of growth in summer, high owing to making the vitality of semi-lignified branch of stock and scion, graft survival rate is higher through document Investigation, has no the propagation method of Acer palmatum grafting of tender branch.
Summary of the invention
Goal of the invention: the object of the present invention is to provide a kind of can protect keep the good fancy points of Acer palmatum propagation method.
Technical scheme: for achieving the above object, a kind of Acer palmatum grafting of tender branch propagation method of the present invention, is characterized in that it is comprised of the following step:
(1) grafting time: summer;
(2) preparation of stock: early spring by life in 2～4 years without damage by disease and insect, the Acer palmatum seedling do not sprouted. according to the dry high target of cultivating of wood, at liftoff 30～100cm place, wipe out branch, it is regerminated and only retain a healthy and strong young sprout after sprouting and let alone growth and make graft stock;
(3) pinching: wipe out spire or the young shoot on stock and scion branch top, impel the lignification of wish row grafting twig;
(4) cut and get scion: the branch of the Acer palmatum tree crown middle and upper part robust growth that clip ornamental value is high, below branch opposite leaf, respectively cut a bevel, on opposite leaf, a distance is cut off branch and is done scion, leaves petiole, wipe out blade, the scion shearing is wrapped with wet cloth;
(5) cut anvil: choose the stock roughly the same with scion thickness and cut off, in the vertical rip cutting in stock cross section, about equally or slightly short, stock bottom retains blade for manufacturing nutrient to the long bevel of the degree of depth and scion according to scion rugosity;
(6) grafting: the scion shearing is inserted immediately to the mouth of splitting of stock, make both both sides or form layer on one side to aim at, then with plastic strip, graft union is all tied up sternly together with clip in scion, only expose a pair of petiole;
(7) connect rear management: after connecing, pour water immediately, about 10 days, will keep earth moistening.Check and survive after 2 weeks, allly budder bud greenly, or petiole one touches to fall to being and survives, and after within 3 weeks, rear port heals completely, can lighten restrictions on.Strengthen water and fertilizer management, prevention and elimination of disease and pests in time.When scion young sprout grows to 30cm left and right, need slotting lush to protect and tie up, prevent windbreak.Graft survival rate reaches 85～95%
Wherein, step (1) is that described grafting time is bright evening of weather eyeball ten days in June to mid-August, avoids high temperature and rainy day at noon;
The described pinching of step (3) is to carry out for 20～30 days before grafting:
Described in step (4), cutting and getting scion is in branch opposite leaf lower end, respectively to become the wedge shape of face length 2.0～2.5cm, and 1.0～1.3cm place straight snips, one cutter above opposite leaf cuts off leaf and retains petiole.
Beneficial effect: adopt grafting seedlings-growing method of the present invention can keep Acer palmatum good view and admire characteristic; In the Acer palmatum season of growth, carry out grafting of tender branch, the callus of grafting joint easily heals, and it becomes with rate up to more than 85%; Stock and the scion of grafting of tender branch are tender and crisp, cut anvil and scion etc. easy and simple to handle fast, compared with stiff wood grafting efficiency, improve more than 30%; Acer palmatum grafting of tender branch reproduction coefficient is high, and the breeding cycle is short.
