Problems solved by technology

However, the long-term use of the above-mentioned types of pesticides and fungicides will cause pathogenic bacteria to develop resistance to the above-mentioned fungicides. If this type of pesticides continue to be used, not only will the economic cost be significantly increased, but also satisfactory control effects cannot be obtained.
In addition, what cannot be ignored is that long-term pesticide application not only affects food safety, but also brings great pressure to environmental protection

Embodiment 1

[0025] The cultivation of embodiment 1 anti-dry rot hickory seedlings

[0026] 1. Selection of scions

[0027] Choose the annual vegetative growth shoots on the adult hickory trees of Zhejiang Hickory and Dabie Mountain Hickory to do the scion. The branch of the scion is 4cm, and it is better to use thick, short internodes, strong and full buds.

[0028] 2. Selection and cultivation of rootstock

[0029] The rootstock seedling raising method adopts the "strawberry type" Hunan hickory nut seeds of the Juglandaceae Carya genus to carry out seed seedling raising.

[0030] Select a strong, medium-sized mature tree of the "strawberry-type" Hunan hickory of the Juglandaceae hickory, and collect a large number of naturally falling fruits after white dew as seeds. After the seeds are germinated, the seeds with strong radicle growth are picked for sowing. Fertilization follows the principle of giving priority to organic fertilizers, supplemented by chemical fertilizers, applying suf...

Embodiment 2

[0034] Embodiment 2 The dry rot pathogenic bacteria inoculation test of the grafted seedlings obtained with Zhejiang hickory as scion and "strawberry type" Hunan hickory as rootstock

[0035] 1. Test site, materials and sources

[0036] Source of pathogenic bacteria inoculation materials: The dry rot pathogenic bacteria "L 1 ".

[0037] Test site and materials: The test site is located in Huangshan Pingshan Walnut Forest Base, Linkeng Village, Longgang Town, Lin'an City. The soil is red-yellow soil prone to pecan dry rot, and the pecan tree is 6-7 years old. Adopt the cultivating method of the grafted seedling described in embodiment 1, take Zhejiang hickory as scion, " strawberry type " Hunan hickory as rootstock, 30 strains of Hunan root hickory Zhejiang hickory obtained, make susceptibility testing material, take 10 strains Zhejiang Anvil walnut was used as the inoculation control.

[0038] Second, dry rot pathogen inoculation method

[0039] (1) Disinfect the surface ...

Embodiment 3

[0050] Embodiment 3 The dry rot pathogenic bacteria inoculation test of grafted seedlings with Dabie pecan as scion and "strawberry type" Hunan pecan as rootstock

[0051] Adopt the cultivating method of the grafting seedling described in embodiment 1, take Dabieshan pecan as scion, " strawberry type " Hunan pecan as rootstock, 28 strains of the Hunan root Dabieshan pecana obtained, make susceptibility testing material, with 10 strains Dabie Mountain pecans were used as inoculation control. The exact same inoculation test as in Example 2 was used to test the resistance of different types of seedlings to dry rot. The test results are as follows:

[0052] The results of the vaccination trials in September 2013 are as follows:

[0053]

[0054]

[0055] The results of the vaccination trials in May 2014 are as follows:

[0056]

[0057] The test results show that: compared with the conventional Dabieshan pecans, the grafted seedlings of the Hunan root Dabieshan pecans ...

Abstract

The invention discloses an anti-dry rot hickory nursery stock grafting cultivation method. According to the method, hickory susceptible to dry rot is used as the scion, and strawberry type Hunan hickory is used as the stock. The hickory nursery stock obtained through grafting cultivation with the method is capable of resisting dry rot, the morbidity of dry rot is near zero, pesticides for resisting dry rot are not needed basically, and in this way, planting cost is reduced, economic benefits are improved, and improvement of drug resistance of pathogenic bacteria and the influence of bactericides on the environment caused by excessive application of bactericides can also be avoided.

Description

technical field [0001] The invention relates to the field of plant protection and cultivation, in particular to a method for grafting and cultivating dry rot-resistant hickory seedlings. Background technique [0002] Carya is a worldwide dry fruit, belonging to Juglandaceae (Juglandaceae) Carya (Carya), and there are 18 species in the whole genus, which are distributed throughout Asia, Europe, America and other continents. There are 5 species of natural distribution in my country, all of which belong to the bare bud hickory group, namely Zhejiang hickory (Caryacathayensis), Hunan hickory (Caryahunanensis W.C.ChengetR.H.ChangexChangetLu), Guizhou hickory (CaryakwewhoweKuangetA.M. Lu), Vietnamese hickory (Carya TonkinensisH.Lec.) and Dabieshan hickory (CaryadabieshanesisM.C.LiuetZ.J.Li). Among all 18 species, there are only two kinds of pecans in the United States and Zhejiang pecans, which are the most widely used in artificial cultivation. [0003] The Zhejiang hickory, the...
