Problems solved by technology

However, because it is a newly cultivated variety, it is greatly affected by the environment, and it has not been able to achieve large-scale and industrialized planting so far.
Due to the influence of season and temperature, the grafting and breeding of Hongxia Yang is generally only carried out in spring, which leads to a low annual production of Hongxia Yang, which cannot meet the market demand

Embodiment Construction

[0017] A method for grafting and propagating Hongxia poplar, comprising the steps of:

[0018] Step 1: rootstock selection; select the red leaf poplar with a ground diameter of 5 cm or more, root length of more than 25 cm, and healthy growth as the root stock, and plant the red leaf poplar root stock in the intelligent greenhouse for nursery nursery. Wherein, the soil used in the nursery is sandy soil, and organic fertilizer is mixed therein, and the ratio of sandy soil to organic fertilizer is 5:1.

[0019] Step 2: Cutting and pre-processing the red leaf poplar described in step 1. The closer the saw cut is to the ground, the better, generally about 5-8cm from the ground, and ensure that the saw cut is flat, and try to protect the upper cortex of the stump. After felling, cover the cut with plastic film or wet soil to prevent the upper part of the rootstock from drying out. spare. During this process, the temperature in the smart greenhouse should be maintained at 15-20°C. ...

Abstract

The invention discloses a grafting propagation method of Hongxiayang poplar, comprising the steps of I, selecting rootstocks; II, felling and pre-treating Hongxiayang poplar of step I; III, selecting one-year-old Hongxiayang plantlets or shoots as scions, which grow robust, have full buds, are free of disease and pest damage, and are greater than 0.5 cm in thickness and about 15 cm in length; IV, grafting the scions of step III to the rootstocks of step II; V, after grafting, spreading to seal joints of the scions and rootstocks with mud; fixing with vertical rods to prevent lodging of the scions during growth; VI, starting to reshaping and pruning 1-3 years after grafting in order to mainly remove or control competitive shoots and base sprouting shoots; VII, transplanting the plantlets with all 2-3 grafted scions survived and with self-own roots grown on the third year. The grafting propagation method of Hongxiayang poplar has the advantages that growth time of Hongxiayang poplar is shortened, the grafting propagation success rate is up to 98.35% and above, and the effect is improved significantly.

Description

technical field [0001] The invention relates to a method for propagating plants, in particular to a method for grafting and propagating poplars, belonging to the technical field of plant propagation. Background technique [0002] Populus Hongxia is a new variety of poplar buds selected and bred by biological high-tech. It changes from bright red at the budding stage to orange-red and golden yellow, the lower leaves turn yellow-green, and orange-red at the leaf-falling stage. The leaves, petioles, veins, seedlings and branches are always bright rose red. The whole growth period can always maintain a tree with three colors, and the shape is stable, the ornamental value is very high, and the color is exactly like the morning glow, so it is named Hongxia Yang. [0003] The original poplar species, such as poplar medium and red poplar, have a single color and limited eye-catching ability, which cannot meet the needs of current consumers and colorful seedlings in scenic gardens. ...
