example 1

[0019]Dig out a length on the ground and be 60cm, width be 50cm, the germination pit that depth is 40cm, spread the cobblestone that one deck thickness is 3cm at the bottom of the pit, spread the fine sand that one deck thickness is 8cm again on the cobblestone, will thin shell mountain Mix walnut seeds and water in a mass ratio of 1:5 and soak for 1 day. After soaking, filter and separate to obtain soaked hickory seeds. Weigh 1 kg of soaked hickory seeds and 3 kg of sand and mix them into the germination pit On the fine sand layer, cover the sand until it is flush with the edge of the germination pit, cut 3 reeds with a length of 20cm, extract the hollow reed core, insert the reed core evenly into the germination pit, and make the bottom of the reed core go straight to the pebbles layer, after leaving standstill for accelerating germination for 1 week, screen and separate the hickory seeds after obtaining accelerating germination, take by weight 5 parts of rapeseed cake, 10 pa...

[0021] Dig out a length on the ground and be 60cm, width be 50cm, the germination pit that depth is 40cm, spread the cobblestone that one deck thickness is 4cm at the bottom of the pit, spread the fine sand that one deck thickness is 9cm again on the cobblestone, will thin shell mountain Walnut seeds and water are mixed at a mass ratio of 1:5 and soaked for 2 days. After soaking, filter and separate to obtain soaked hickory seeds. Weigh 1 kg of soaked hickory seeds and 5 kg of sand and mix them into the germination pit On the fine sand layer, cover the sand until it is flush with the edge of the germination pit, cut 4 reeds with a length of 25cm, extract the hollow reed core, and insert the reed core evenly into the germination pit, so that the bottom of the reed core reaches the pebbles layer, after leaving standstill for accelerating germination for 1 week, screen and separate the hickory seeds after obtaining accelerating germination, take by weight 8 parts of rapeseed cake,...

Abstract

The invention discloses a thin-shell pecan grafting method, and belongs to the technical field of pecan planting. The method includes the steps: firstly, cultivating thin-shell pecan seedlings, and taking the seedlings as grafted branches by the aid of high cell division ability of seedling stage; secondly, collecting terminal buds and first side buds of the seedlings with most auxin, mashing the terminal buds and the first side buds into slurry, mixing the slurry, peach gum and potassium nitrate to obtain concentrated solution with the auxin and film-forming ability, coating graft unions with the concentrated solution to form cell active layers, breaking through diaphragms generated by dead cell of the graft unions to form callus tissues, further differentiating the callus tissues to form new inward xylem and new outward phloem, performing sieve tube communication on the xylem and phloem of grafted seedlings, and communicating dredge tissues to improve graft healing ability. A film forming matter in the concentrated solution can form uniform protection film layers at grafted gaps, sap and water loss is prevented, infestation of germs on grafting wounds is avoided, and grafting survival rate is further increased.

Description

technical field [0001] The invention discloses a method for grafting thin-shell pecans, belonging to the technical field of pecan grafting. Background technique [0002] Thin-shelled hickory, also known as American hickory, belongs to the Juglandaceae family. Native to the United States and Mexico, it is one of the most important oil-bearing dried fruit tree species in the world. Its shell is thin and easy to peel, its kernels are thick and fleshy, and it has a delicious taste and high nutritional value. The trunk is straight, the tree shape is beautiful, the roots are deep and the leaves are luxuriant, and it is an excellent tree species for greening and gardening around. At the same time, the wood is tough and dense, the core material is dark red, the sapwood is yellow-white, elastic, and not easy to deform and crack. It is an excellent timber tree species for construction and high-end furniture. Therefore, pecan is an excellent economic tree species with wide applicatio...
