Problems solved by technology

Grafting propagation needs to cultivate the black locust more than biennial as the rootstock first, and then graft the black locust as the scion on the rootstock, so it needs a long nursery stock cultivation period, which increases the seedling cost; the promotion and promotion of the black locust in landscaping is limited. application

Embodiment 1

[0018] Mix perlite, vermiculite and peat at a volume ratio of 1:1:1 to make a cutting substrate, dilute it with 50% carbendazim wettable powder 800-1000 times and spray it for disinfection before use; dissolve 200 mg of indole butyric acid In 40-50ml of 95% ethanol, add 4.0mg of ammonium molybdate, vitamin B 1 After 2.0 mg, add water to 1 kg, mix well and set aside; in the early morning or cloudy day in early June, select Robinia golden leaf branches that are healthy and free from diseases and insect pests. Cut the branches with a length of 8-12cm and a diameter of 0.3-0.8cm as cuttings. The upper and lower cuts of the cuttings are cut flat, and the distance between the upper cut and the cut bud is 1.0-1.5cm. For 2-4 leaflets in the leaves, after cutting off the rest of the leaves, dip the base of the cuttings in 0.1% potassium permanganate solution for 1 minute for disinfection, then soak in the rooting agent for 2 hours. Insert the prepared cutting matrix and water thorough...

Embodiment 2

[0020] Mix perlite, vermiculite and peat at a volume ratio of 1:2:1 to make a cutting substrate, dilute it with 50% carbendazim wettable powder 800-1000 times and spray it for disinfection before use; dissolve 400 mg of indole butyric acid In 40-50ml of 95% ethanol, add 5.0mg of ammonium molybdate, vitamin B 1 After 4.0 mg, add water to 1 kg, mix well and set aside; in the early morning or cloudy day in mid-June, select robust branches of Robinia aureus aureus that year, free of diseases and insect pests. Cut the branches with a length of 8-12cm and a diameter of 0.3-0.8cm as cuttings. The upper and lower cuts of the cuttings are cut flat, and the distance between the upper cut and the cut bud is 1.0-1.5cm. For the 2-4 leaflets in the leaves, cut off the remaining leaves, dip the base of the cuttings in 0.1% potassium permanganate solution for 1 minute for disinfection, and soak in the rooting agent for 1 hour. Insert the prepared cutting matrix and water thoroughly; in a ful...

Embodiment 3

[0022] Mix perlite, vermiculite and peat at a volume ratio of 1:1:1 to make a cutting substrate, dilute it with 50% carbendazim wettable powder 800-1000 times and spray it for disinfection before use; dissolve 500 mg of indole butyric acid In 40-50ml of 95% ethanol, add 6.0mg of ammonium molybdate, vitamin B 1 After 4.0 mg, add water to 1 kg, mix well and set aside; in the early morning or cloudy day in late June, choose robust branches of Robinia aureus aureus that year, free of diseases and insect pests. Cut the branches with a length of 8-12cm and a diameter of 0.3-0.8cm as cuttings. The upper and lower cuts of the cuttings are cut flat, and the distance between the upper cut and the cut bud is 1.0-1.5cm.

Abstract

The invention discloses a shoot cutting propagation method of robinia pseudoacacia aurea. The shoot cutting propagation method comprises the following steps of: (1) selecting appropriate cutting time; (2) preparing a cutting matrix; (3) preparing a rooting agent; (4) preparing cutting slips; and (5) performing management and (6) transplanting after cuttage. The cutting propagation method provided by the invention is capable of remaining excellent fancy points of the stock plant of robinia pseudoacacia aurea; and the cutting propagation method is high in propagation coefficient, and simple and convenient to operate, and the plants grow strong and tidily; therefore, the shoot cutting propagation method of robinia pseudoacacia aurea has great practice and popularization significance in propagation production of ornamental nursery stocks of robinia pseudoacacia aurea.

Description

technical field [0001] The invention relates to a method for asexual propagation of plants, in particular to a method for cutting propagation of black locust acacia twigs. Background technique [0002] Robinia pseudoacacia 'Frisia' is a deciduous broad-leaved tree of the family Papilionaceae (Papilionaceae) Robinia L., with a cylindrical crown, thorny branchlets, and odd pinnate compound leaves. Turns yellow-green, orange-yellow in autumn, blooms in early summer, white flowers, flowering period from May to June. This species is native to North America and was introduced to my country at the end of the 19th century. This species is light-loving, resistant to drought and barrenness, has strong adaptability to soil, strong germination ability, and fast growth. Robinia pseudoacacia is an ornamental species with colorful leaves, which can be used as shade trees, street trees and other landscape greening applications. [0003] The asexual reproduction of plants can maintain the...
