The invention relates to a gobi grape field hard branch grafting method which comprises the following steps that (1) a place where terrain is flat and the diameters of sand stones are smaller than 5cm in gobi is selected for building of a vineyard; (2) the vineyard is built, namely first, ditching is carried out in the vineyard, then surface soil is padded, cow and sheep manure is mixed, subsoil or sandy soil covers the manure, finally flattening is carried out to form a shallow ditch; second, a cement frame column row is inserted on one side of the shallow ditch, 3-4 iron wires are used for being pulled on the cement frame columns; third, grape stock seedlings are processed and then are fixedly planted in a fix-planting hole; fourth, stock management is carried out according to a conventional method, stocks which need grafting are obtained; (3) grafting time is selected; (4) pinching processing is carried out on the stocks which need grafting; (5) branches full with annual bud eyes are used as scions and are stored for a winter, then scion nursery stocks are obtained; (6) the scions are activated, then the scions which need grafting are obtained; (7) grafting is carried out; (8) field management is carried out; (9) planting management is carried out according to the conventional method. According to the method, grafting time can be prolonged, and under the situation that the anti-freezing stocks are used, the phenomena of root freezing of grape planting are avoided.

The invention discloses a method for the high square bud grafting of Juglans sigllata Dode. The method comprises the following steps: selection of the appropriate grafting period, collection and storage of scions as well as the grafting, and management after grafting. According to the invention, a summer high square bud grafting method is adopted to reduce the erosion to a grafting bud caused by the bleeding sap of the Juglans sigllata Dode, so that the high grafting optimization for Juglans sigllata Dode low yielding trees is successfully realized, the grafting survival rate reaches 78 to 92 percent, in addition, wounds can be healed up quickly, the operation is simple, and the grafting efficiency is high and a tree crown can recover quickly, so that the breed improvement problem of Juglans sigllata Dode in Guizhou mountainous area is solved. The method for the high square bud grafting of the Juglans sigllata Dode is simple and low in cost, and has a good using effect and a broad prospect for industrialization application.

The invention discloses a novel aging mulberry rejuvenation and improvement method capable of allowing the yield to be increased in the same year after the half-year grafting time, and belongs to the technical field of gardening mulberry cultivation. The method is characterized in that ear buds are inserted in the same direction; winter bud grafting and spring bud grafting are used simultaneously; and sawed pile multi-bud grafting is performed. An improved spring sawed pile bud grafting (ear bud inserting in the same direction and multi-bud grafting) is applied by the method, and a winter skin cutting and bud grafting method is successfully applied to winter and early spring sawed pile bud grafting by using a method of skiving a rough bark of a stock, so that the grafting time is prolonged to half a year during which ear strips are not required to be stored; the number of grafted ear buds of each mulberry is increased from 2-3 to 5-10 by adopting the multi-bud grafting, so that the yield can be increased by 50-200% in the same grafting year, and mulberry tree type cultivation can be accomplished on time; and a grafting body and a stock tree body can be healed tightly and firmly by adopting the ear bud inserting in the same direction, so that the long-term survival rate of the graft body is high. According to the method, the ear bud survival rate is not less than 97%; the mulberry survival rate is not less than 99%; and the method can be widely applied to renewal rejuvenation and variety improvement of aging trees of various mulberry fields, four-edge mulberries, daxing mulberries, coriaria sinia and arbor mulberries.

The invention belongs to the technical field of idesia polycarpa grafting, and discloses an idesia polycarpa seedling sleeve grafting method. Idesia polycarpa seeds are sown and true stocks are cultivated; the idesia polycarpa stock seeds are sown 20 days before germination of female plants of idesia polycarpa; a PC hollow-board greenhouse is used for idesia-polycarpa plug seedling production; resting-bud tender leaves with two leaves and one heart and terminal-bud tender leaves with two leaves and one heart are collected to serve as scions; sleeve pipes with the diameter of 3.0 mm are used for grafting. A large amount of female scions are obtained, and the problem that the scions are not enough in the production is solved; plastic sleeves are adopted, moisture is retained, water loss is prevented, invasion of bacteria is prevented, and the survival rate can reach 95% or above; the plastic sleeves are adopted for grafting, the grafting speed is high, operation is simple, most labor issaved, the cost is low, the idesia polycarpa grafting speed is largely improved, and the number of idesia polycarpa grafting seedlings can be significantly improved; the grafting time is early, the goal of idesia polycarpa for sell in those years can be achieved, and the time required for idesia polycarpa for sell is shortened by one year.
