Embodiment 1

[0021] A kind of golden locust tree grafting breeding technique, mainly comprises the following several steps:

[0022] Select the big seedling of Chinese pagoda tree that diameter is 6cm, trunk is straighter as Zhe Mu; Select annual growth length to be 10cm, diameter is the golden pagoda tree hard branch of 0.8cm as scion, and scion wax seal, be placed in and store in cool and cool leeward place, because the weather is relatively cold For reasons such as heat, wax sealing the scion after harvesting can avoid excessive time, reduce water loss, and improve survival rate.

[0023] After the Chinese pagoda tree germinates, cut a 5cm incision on the opposite side of the growth lower end of the above-mentioned wax-sealed golden pagoda tree scion and the upper end bud, and cut a small slope on the back side, and the length of the cut will exceed the pith center of the scion; separate the above-mentioned Chinese pagoda tree seedlings A small incision was cut vertically in the epiderm...

Embodiment 2

[0027] A kind of golden locust tree grafting breeding technique, mainly comprises the following several steps:

[0028] Select the big seedling of Chinese pagoda tree that diameter is 10cm, trunk is straighter as Zhe Mu; Select annual growth length to be 15cm, diameter is the golden pagoda tree hard branch of 1.2cm as scion, and scion wax seal, be placed in and store in cool and cool leeward place, because the weather is relatively cold For reasons such as heat, wax sealing the scion after harvesting can avoid excessive time, reduce water loss, and improve survival rate.

[0029] After the Chinese pagoda tree germinates, cut an 8cm otch on the opposite side of the growth lower end of the above-mentioned wax-sealed golden pagoda tree scion and the upper end bud, and cut a small inclined plane on the back side, and the length of the cut will exceed the pith center of the scion; A small incision was cut vertically in the epidermis at 3m from the ground. The kerf is required to b...

Embodiment 3

[0033] A kind of golden locust tree grafting breeding technique, mainly comprises the following several steps:

[0034] Select the big seedlings of Chinese pagoda tree with a diameter of 8cm and straight trunk as Zhemu; select the hard branch of golden pagoda tree with an annual growth length of 13cm and a diameter of 1cm as the scion, seal the scion with wax, and place it in a cool and leeward place for storage. For other reasons, sealing the scion with wax after harvesting can avoid excessive time, reduce water loss, and improve survival rate.

[0035] After the Chinese pagoda tree germinates, cut a 6cm otch on the lower end of the growth of the above-mentioned wax-sealed golden pagoda tree scion and the opposite side of the upper bud, and cut a small inclined plane on the back side, and the length of the cut will exceed the pith center of the scion; A small incision was cut vertically in the epidermis at 2.5m from the ground. The kerf should be smooth and not damage the co...

Abstract

The invention discloses a grafting and breeding technology of sophora japonica 'Winter Gold'. The grafting and breeding technology of the sophora japonica 'Winter Gold' mainly comprises the followingsteps: selecting rootstock and storing a scion, namely selecting sophora japonica with an appropriate thickness as rootstock, selecting a hardwood branch with an appropriate length as a scion, and storing the scion; carrying out grafting, namely inserting the scion into an upper end of the rootstock, and fixing a joint with a plastic strip; carrying out post-grafting management, namely observing germination condition at an incision on the rootstock after the grafting, and timely removing seedlings; and then, carrying out preventing, treating and top dressing, namely appropriately spraying a pesticide or applying a top dressing according to growth situation. The sophora japonica 'Winter Gold' grafted according to the grafting and breeding technology is robust in growth, free of diseases, insects and pests, relatively high in survival rate, and relatively high in ornamental values.

Description

technical field [0001] The invention relates to the field of planting seedlings, and more specifically, relates to a technique for grafting and breeding golden locust trees. Background technique [0002] Golden locust tree, also known as Jinzhi locust tree, Jinzhi national locust tree, etc., is a deciduous tree of the Fabaceae locust tree. It grows in Shandong, Hebei, Baoding Dahan Oasis Garden, Shanxi, Henan, Shaanxi and other places. It is one of the varieties of national locust tree. The branches are golden yellow, especially in winter, this golden yellow is thicker and more gorgeous, with a unique style, quite rich in the style of garden woody flowers, and has high ornamental value. It is one of the commonly used tree species in landscaping. [0003] Because the planting of golden locust trees mostly adopts grafting rootstock grafting and breeding technology, but at present in the nursery stock planting industry, many farmers have insufficient grafting technology and a ...
