Embodiment 1

[0028] The grafting breeding method of the present embodiment golden leaf catalpa comprises the following steps:

[0029] S1, the selection of rootstock: select the juniper cypress of plant height 1.5 meters as rootstock;

[0030] S2, the selection of scions: in March, select the branches with full buds on the golden leaf catalpa, and cut them off as scions;

[0031] S3, treatment before scion grafting: soak the scion cut in step S2 with a treatment agent for 10 hours, the treatment agent consists of 10 parts of yellow vinegar, 5 parts of magnesium nutrient, 8 parts of ammonium sulfate, 8 parts of potassium chloride, naphthaleneacetic acid 10 parts and 80 parts of deionized water are mixed;

[0032] S4, grafting: use a knife to cut the root of the scion into a wedge-shaped inclined plane, cut out a "T"-shaped grafting joint at the grafting place of the rootstock with a knife and insert the scion into the grafting joint of the rootstock, then tie it tightly with a plastic film...

Abstract

The invention provides a grafting breeding method for catalpa bignonioides, and relates to the technical field of ornamental tree planting. The grafting breeding method includes the steps of stock selecting, scion selecting, treating before scion grafting, grafting, unbundling, unwanted sprout removing, shaping and pruning, plant-transpiration-inhibitor and rooting-agent periodical spraying, nutrient and water managing and disease and pest controlling. According to the grafting breeding method for the catalpa bignonioides, the method is easy to operate and high in grafting survival rate, and the bred catalpa bignonioides is high in growth speed, hairchested in branch and trunk and dense and bright in leaf, and has the quite-high viewing value.

Description

technical field [0001] The invention relates to the technical field of ornamental tree planting, in particular to a grafting and breeding method of catalpa japonica. Background technique [0002] Golden Leaf Catalpa, Bignoniaceae, Catalpa. Native to the southeastern United States, it is now cultivated in southern Liaoning, Beijing and Shandong. It is a deciduous tree with a height of 15 meters and a wide crown.
