Problems solved by technology

[0003] The seeds of horse chestnut are edible, but they taste bitter and astringent when eaten directly. They need to be boiled in alkaline water before they can be eaten. The taste is like chestnut
[0004] Aesculus tree species, such as Lancang Aesculus, multi-veined Aescin, and large-leaf Aesculus, all grow slowly and have poor natural renewal ability. High, the vitality of seeds is difficult to maintain, so the survival rate of sowing seedlings is low

Embodiment 1

[0025] Respectively with Lancang horse chestnut, big-leaf horse chestnut as scion, horse chestnut as the grafting seedling raising method of rootstock, comprises the following steps:

[0026] (1), rootstock selection and processing: select the 1-2 year old horse chestnut seedlings with strong growth and well-developed root system to do the grafting rootstock; 25 days before grafting, the rootstock is cut horizontally at 15-20cm on the ground, and the rootstock treatment liquid is applied Afterwards, tie the cut surface tightly with plastic wrap for subsequent use; the rootstock treatment liquid is: a mixed solution of natural VE and sesame oil; the ratio of natural VE and sesame oil is 1:25.

[0027] (2), scion selection and processing: select the middle part of the annual branch with strong growth, good lignification, full buds and even distribution, and no damage by diseases and insect pests to make the scion; the length of the picking strip is 30-50cm, and the length of the ...

Abstract

The invention relates to a method for grafting seedling culture of a new horse chestnut variety. The method mainly comprises a step (1) of selecting 1-2-year horse chestnut seedlings as grafting stocks; in 20-30 days before grafting, transversely cutting off the stocks at the positions of 15-20 cm on the ground, coating the stock with a stock treating liquid, and then using a preservative film to tighten sections; a step (2) of selecting middle parts of annual branches growing robustly and having good growth vigor as scions, wherein collected scion lengths are 30-50 cm, the scion lengths are controlled to be 3-5 cm, and the thickness is controlled to be 0.6-0.7 cm; dipping the scion treating liquid, and performing grafting while performing dipping; a step (3) of performing grafting: cutting off 0.1-0.2 cm of the upper portions of the stock sections and then instantly performing grafting with the scions through a tongue grafting method; a step (4) of performing wax sealing of the scions; and a step (5) of performing graded temperature management after the grafting. The method has the advantages that the seedling culture period is short, the grafting survival rate is high, the new variety grows quickly after grafting, and the stress resistance is high.

Description

technical field [0001] The invention relates to the technical field of horse chestnut seedling raising, in particular to a method for grafting seedling raising of a new horse chestnut variety. Background technique [0002] Horse chestnut (scientific name: Aesculus chinensis Bunge): It is a deciduous tree, up to 25 meters, with dark brown or taupe bark, branchlets, cylindrical, yellowish brown or taupe, with light yellow lenticels. The winter buds are large and resinous. Palmately compound leaves, composed of 5-7 small, dark green, glabrous above, and glabrous below except that the bases of the middle ribs and lateral veins are sparsely pubescent when young. The inflorescence is cylindrical, the total axis of the inflorescence is puberulent, and the inflorescence is usually composed of 5-10 flowers, extending flat and obliquely, with puberulent. Flowers polygamous, male and hermaphroditic, calyx tubular-bell-shaped, petals 4, white, oblong-obovate to oblong-oblanceolate. F...
