Problems solved by technology

[0004] At present, there are two main problems affecting the rooting of blueberry cuttings: one is that the survival rate of cuttings is not high; the other is that after the cuttings survive, it is difficult to form adventitious roots

Embodiment 1

[0025] Five common blueberry varieties, including Yuanlan, Brilliant, Misty, Dingfeng, and Tiffan, were used as test materials to study the effects of different hormone types, different contents, different hormone ratios, and different cutting substrates on their rooting rate. Then determine the best treatment measures.

[0026] As cuttings, blueberry materials are free from pests and diseases, have uniform internode length, full buds, no mechanical damage, and grow robustly. Spray the cut cuttings with water after harvesting, store them in a foam box at low temperature to prevent water from evaporating, and then immediately trim the branches into 7-10cm cuttings with 4-5 axillary buds and 1-2 leaves on the top. Cut at 1 cm, cut obliquely at 45° at the lower cut, and treat with hormones in time, and cut into the substrate.

[0027] Specifically, the following four treatments were used to compare the effects:

[0028] 1. Variety treatment: cut 150 cuttings of the same growth ...

Embodiment 2

[0035] The influence of embodiment 2 different hormone types and concentrations on rooting rate

[0036] In this experiment, Canlan was used as the test material, and the two-factor grouping experiment of hormone type and concentration ratio was carried out. 9 treatments were set up. Each treatment was randomly divided into 3 groups, and each treatment group consisted of 50 cuttings.

[0037] The hormones are NAA, IBA, and NAA:IBA mixed hormones. Both NAA and IBA have 3 concentration gradients of 100mg / L, 200mg / L, and 300mg / L. The three ratios of mixed hormones are 1:1, 1:2, and 2. : 1, after soaking the base of the cuttings for 2 hours, cuttings were carried out, and the comparison was soaked in deionized water.

[0038] After 110 days of cutting, the rooting rate of each treatment was counted, and the root system was cut from the rhizome, scanned with a root scanner (Epson Perfection V700Photo, Japan), and the obtained image was analyzed with WinRHIZO software for its root s...

Embodiment 3

[0055] Embodiment 3 A kind of treatment measure that improves rooting rate of blueberry cuttings, the steps are as follows:

[0056] (1) Selecting branches: select green branches of the year that are free from diseases and insect pests, have uniform internode length, full buds, no mechanical damage, and grow robustly, or the side buds of the secondary branches have just germinated and have not stopped growing semi-lignified blueberry varieties that are easy to root. shoots as cuttings;

[0057] (2) Substrate compounding: mix peat, vermiculite, and perlite according to the volume ratio of 1:1:1, and pour water thoroughly, and sterilize with 1000 times carbendazim and 5% potassium permanganate solution 3 days before cutting ;

[0058] (3) Cutting treatment: take the cuttings cut in step (1) and spray them with water after harvesting, store them at low temperature to prevent water evaporation, and then promptly trim the branches to 7-10cm with 4-5 axillary buds and 1-2 leaf cut...

Abstract

The invention relates to a hormone treatment measure for increasing the cutting rooting rate of blueberries, and belongs to the technical field of cutting propagation. By selecting and trimming cutting slips, after the roots of the trimmed cutting slips are soaked with mixed hormones with the ratio of NAA to IBA being 2:1 for 2 h, the cutting slips are inserted into a mixed substrate with the volume ratio of peat to vermiculite to perlite being 1:1:1, the cutting slips are immediately placed in a small shed for conventional management after being cut, the temperature is controlled to range from 20 DEG C to 30 DEG C, the relative humidity is controlled to range from 80% to 90%, and 100-fold carbendazim is sprayed once every week for sterilization. The method is simple, easy to learn, high in operability, good in rooting effect and high in application value, the rooting rate can reach 78.67% to the maximum, and the total root length, the diameter and the root tip number of a root systemcan be remarkably increased.

Description

technical field [0001] The invention relates to a hormone treatment measure for increasing the rooting rate of blueberry cuttings, and belongs to the technical field of cutting propagation. Background technique [0002] Blueberry (Vaccinium ssp.L.) is a perennial deciduous shrub of the genus Vaccinium in the family Rhododendronaceae. It is mainly native to North America. It is a fruit tree with high economic value and great development potential. Its fruit is often rich in antioxidants, anthocyanins, flavonoids and other substances that are closely related to the scavenging of free radicals in the human body, inhibiting and reversing human aging, so it has good anti-aging, anti-cancer, improving immunity and vision effects. Therefore, it was selected as one of the "Top Ten Best Nutritious Foods" by the American Time Magazine, one of the "Five Healthy Fruits" for humans by the International Food and Agriculture Organization, and the "Best Nutritional Value for Humans" fruit b...
