Embodiment

[0019] A method for grafting thin shell pecans with high survival rate is characterized in that, it is carried out according to the following steps:

[0020] a. Rootstock selection:

[0021] The used rootstock of grafting is the seedling stock that hickory nut seed bred, and seedling age is 1-2 year, and the processing mode of rootstock is transplanting, and the selection stock thickness is 1-1.2cm;

[0022] b. Scion selection:

[0023] In the middle of March in spring, select 1-2 year old branches with strong growth and full bud eyes on a good single plant, and collect scions with a length of 30-40cm and a thickness of 1-1.5cm. The scion has 2-4 buds, and cut them off after harvesting For the leaves, the branches are wax-sealed, and the scions are stored in a refrigerator at 4-6°C, and the scions should be picked as they are harvested;

[0024] c. Grafting method:

[0025] When grafting, cut off the rootstock at the grafting site, select the full and full buds in the middl...

Abstract

The invention discloses a high-survival-rate grafting method for carya illinoensis. The method is characterized by comprising the steps: rootstocks for being grafted are nursery-grown plants cultured from carya illinoensis seeds, and a rootstock treatment mode is transplanting; branches, which are robust in growth and plump in bud, are selected from excellent single plants and are subjected to wax sealing treatment, and scions are grafted while the scions are picked; grafted parts of the rootstocks are trimmed off during grafting, full and plump buds of middle-lower parts of the scions are selected as scion buds, grafting is carried out by adopting a bud-sticking grafting method, lower ends of the scion buds are aligned with cuts of the rootstocks, and plastic films are used for carrying out binding for moisture preserving; and in a scion and rootstock healing stage, the temperature and humidity of a greenhouse are controlled, and sunshine direct-sunning is avoided until the scions and the rootstocks are completely healed and grafted seedlings survive.

Description

technical field [0001] The invention relates to the field of planting, in particular to a method for grafting thin-shell pecans with high survival rate. Background technique [0002] Thin-shelled hickory is a plant of the genus Hickory in the family Juglandaceae. It is an ecological and economical tree species integrating high-grade thousand fruits, high-grade woody oil, high-quality hard broadwood and landscaping, and has certain economic, social and ecological benefits. Benefits, broad prospects for development, has developed rapidly in recent years. The propagation of pecan seedlings includes rootstock cultivation and grafting. Pecan has deep roots and is not prone to lateral roots. The traditional field seedling cultivation method has fewer lateral roots and a low survival rate for transplanting. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a method for grafting pecans with high survival rate, and the pe...
