Embodiment 1

[0019] A kind of walnut ectomycorrhizal infection method of the present invention, comprises the following steps:

[0020] (1) Preparation of mycorrhizal infection substrate: at 240m covered with sunshade net 2 In a standard greenhouse, mix 3 parts of humus soil, 2 parts of vermiculite and 3 parts of edible fungus waste, the pH value is 5.5, and form a raised bed with a width of 90 cm and a height of 25 cm for later use;

[0021] (2) Seed collection: Peel and dry the walnut mother tree seeds that have early fruiting, high and stable yield, strong adaptability, high kernel yield and high oil content, then dry them in the sun for 4 days, and store them in a cold storage at 0°C with cloth bags;

[0022] (3) Seed soaking: From January to February of the following year, use 0.1% H 2 SO 4 Soak the seeds in the solution for 6 hours, then remove them for sand storage and accelerate germination. When most of the seeds swell and crack, they can be sown;

[0023] (4) Sowing: mix the c...

Embodiment 2

[0033] A kind of walnut ectomycorrhizal infection method of the present invention, comprises the following steps:

[0034] (1) Preparation of mycorrhizal infection substrate: at 240m covered with sunshade net 2 In a standard greenhouse, mix 4 parts of humus soil, 3 parts of vermiculite and 4 parts of edible fungus waste, the pH value is 6.5, and form a raised bed with a width of 100 cm and a height of 30 cm for later use;

[0035] (2) Seed collection: Peel the seeds of walnut mother tree that have early fruiting, high and stable yield, strong adaptability, high kernel yield and high oil content, then dry them in the sun for 5 days, and store them in a cold storage at 4°C with a cloth bag;

[0036] (3) Seed soaking: From January to February of the following year, use 0.3% H 2 SO 4 Soak the seeds in the solution for 8 hours, then take them out and store them in sand to accelerate germination. When most of the seeds swell and crack, they can be sown;

[0037] (4) Sowing: mix t...

Abstract

The invention discloses a method for infecting walnut ectomycorrhizae. The method comprises the steps of preparation of mycorrhiza infection substrate, seed collection, seed soaking, seeding, field management and transplantation. The method is simple in technology and easy to popularize, and the seed germination rate can be as high as 90-95% and is improved by 5-10 % compared with a conventional method. Seeds grow quickly, and the seedling heights can be 100-120 cm in a year after the seeding and are increased by 20-30 cm compared with the conventional method. Edible fungus waste is utilized as the infection substrate, the production cost can be reduced by 20%, the survival rate can be over 95% after the afforestation and is improved by 5-10% compared with the conventional method, the forest resistance after infection through self-made cantharellus cibarius liquid strains is improved by 10-20% compared with the conventional method, and the yield can be improved by 5-10%. According to the method, large-scale and industrial production of walnut mycorrhization seedlings can be achieved, and a way for becoming rich is opened for peasants in mountainous areas of Guizhou.

Description

technical field [0001] The invention relates to a walnut ectomycorrhizal infection method, which belongs to the technical field of mycorrhizal infection. Background technique [0002] Walnut( Juglansregia L.) is a plant of the genus Juglandaceae. It is an important woody oil plant and a high-quality edible dried fruit tree species. It is one of the "four major dried fruits in the world"; it is widely distributed in Guizhou and has a large planting area. It is the main characteristic economic forest in Guizhou Province , and obtained considerable ecological and economic benefits, and played a huge role in the development of the national economy and the construction of the ecological environment in Guizhou Province. Walnut trees are full of treasures. Through the processing industry, walnut fruit, walnut kernels, walnut oil, walnut oil capsules, walnut powder, walnut lozenges, walnut milk, walnut handicrafts and many other products can be produced. According to the current p...
