Problems solved by technology

However, during the cutting propagation process, the upper and lower incisions caused physical and mechanical damage to the cuttings when the cuttings were cut, and the exposure of the incisions to the air would easily lead to the oxidation of tannins in the cuttings to form quinones, hindering the rooting of the cuttings, and even causing the cuttings to brown and rot , affecting the survival rate of hazelnut cutting propagation

Embodiment 1

[0030] In mid-June 2016, select robust plants free from diseases and insect pests as the objects of ear picking, collect robust 1-year-old branches with a high degree of lignification at the base of the tree, and cut the middle and upper parts of the branches where the color changes from green to gray. The lower 15cm, the length of the branches is 50-60cm, spray water to moisturize immediately after picking the ear; cut the cuttings in a cool place, cut the top, middle and lower sections separately, avoid mixing varieties, and each ear has 3-4 internodes , length 8-10cm, first remove the top tip and keep the top growth point, keep 2 young leaves, keep the upper 2 leaves in the middle and base sections, cut off half of the leaves, keep the stem section above the first bud 0.5cm flat, cut the lower part of the cuttings Cut obliquely, wrap the lower part of the obliquely cut cuttings with silk fabric, make the silk fabric close to the incision, and then immediately immerse in the ...

Embodiment 2

[0032] In the first ten days of July, 2016, we selected robust plants free from diseases and insect pests as ear picking objects, and collected robust 1-year-old branches with a high degree of lignification at the base of the tree, and cut the middle and upper part of the branches where the color changed from green to gray. The lower 15cm, the length of the branches is 50-60cm, spray water to moisturize immediately after picking the ear; cut the cuttings in a cool place, cut the top, middle and lower sections separately, avoid mixing varieties, and each ear has 3-4 internodes , length 8-10cm, first remove the top tip and keep the top growth point, keep 2 young leaves, keep the upper 2 leaves in the middle and base sections, cut off half of the leaves, keep the stem section above the first bud 0.5cm flat, cut the lower part of the cuttings Cut obliquely, wrap the lower part of the obliquely cut cuttings with silk fabric, make the silk fabric close to the incision, and then immed...

Embodiment 3

[0034] In the last ten days of June 2016, select robust plants without pests and diseases as the ear-picking objects, collect robust 1-year-old branches with a high degree of lignification at the base of the tree, and cut the parts where the color of the upper part of the branches changes from green to gray. The lower 15cm, the length of the branches is 50-60cm, spray water to moisturize immediately after picking the ear; cut the cuttings in a cool place, cut the top, middle and lower sections separately, avoid mixing varieties, and each ear has 3-4 internodes , length 8-10cm, first remove the top tip and keep the top growth point, keep 2 young leaves, keep the upper 2 leaves in the middle and base sections, cut off half of the leaves, keep the stem section above the first bud 0.5cm flat, cut the lower part of the cuttings Cut obliquely, wrap the lower part of the obliquely cut cuttings with silk fabric, make the silk fabric close to the incision, and then immediately immerse i...

Abstract

The invention discloses a filbert shoot cutting seedling raising method. The filbert shoot cutting seedling raising method comprises, from middle June to early July, choosing robust, pest and disease-free plants as objects to cut, collecting one-year-old branches robust in growth and high in degree of lignification from the base of a tree, clipping out tender parts of the middle and upper portionsof the branches, performing scion cutting and immersion treatment and then planting the clipped parts in a nursery bed with a temperature of 25-28 DEG C, an air humidity higher than 90% and a substrate moisture content higher than 50%-60% for seedling raising. According to the filbert shoot cutting seedling raising method, tannin molecules can enter into amorphous regions of silk fibroin fiber and settle inside the fiber by being bonded with the silk fibroin fiber via hydrogen bonds, Van der Waals' force and the like, and are in multi-point bond in forms of hydrogen bonds with peptidyl-OH, -NH-CO-, -NH2 and-COOH of proteins of sericin to immobilize the sericin; immersion in acetic acid aqueous solution can extrude a large amount of tannin inside scion cells and absorb the tannin onto silks to reduce the content of tannin inside scions as well as the browning amount of tannin, to avoid browning and rotting of cuts of the scions due to oxidation of tannin, to promote rooting of the scions and further to improve the cutting survival rate.

Description

technical field [0001] The invention relates to the technical field of fruit tree seedling raising, in particular to a method for raising seedlings by cuttings of hazelnut twigs. Background technique [0002] Hazelnut, also known as mountain chestnut, sharp chestnut, and beetle, belongs to the plant of the genus Corylus in the family Betaceae (corylaceae). It is an excellent tree species with both fruit and material. Its fruit looks like a chestnut, with a hard shell, fat white and round kernels, aroma, and a large oil content. It tastes particularly delicious and has a lingering aftertaste. Therefore, it has become the most popular nut food. Appellation, together with almonds, walnuts, and cashews, is called "the four major nuts". Hazelnuts are rich in nutrients. In addition to protein, fat, and sugar, the nuts are also rich in carotene, vitamin B1, vitamin B2, and vitamin E; the 8 kinds of amino acids needed by the human body are all available in hazelnuts, and their con...
