Embodiment 1

[0050] A method for cultivating chestnut seedlings by bud-stock grafting in symbiosis with rhizomes, comprising the following steps:

[0051] 1) germination of stock species

[0052] In the northern part of Qinling Mountains, Shaanxi Province, in early October, after the chestnut matures, choose seeds with good maturity and no pests and diseases to soak the seeds in a potassium permanganate solution with a mass concentration of 0.5% for 2 hours, rinse them with clean water, spread them on the sand bed in layers, and cover them. The sand layer is poured with enough saturated water, and the sand layer is covered with a breathable film; the humidity of the sand bed is kept at 60%, and the temperature is controlled at 15-20°C for 15-20 days;

[0053] When the seed radicle grows to 2-3cm, cut off the radicle root tip from the root tip of 1.5cm, then soak in 50ppm naphthaleneacetic acid for 1-3s, and move it into the greenhouse to accelerate germination; cut off the root tip and soa...

Embodiment 2

[0072] A method for cultivating chestnut seedlings by bud-stock grafting in symbiosis with rhizomes, comprising the following steps:

[0073] 1) Collection and sand storage of stock species

[0074] In Baoji, Shaanxi Province, at the beginning of October, the local excellent tree species, the Chestnut tree, were selected to collect seeds, and the seeds with good maturity and no pests and diseases were selected, and the seeds were soaked in a potassium permanganate solution with a mass concentration of 2% to 3% for 30 minutes, and then the sand was taken out; Humidity is required to be held in a ball, loose or loose, and the temperature should be controlled within 15°C; turn it every 7 days.

[0075] 2) Germination

[0076] Choose the leeward sunny, convenient drainage and irrigation, and build plastic greenhouses on sandy loam soil with a width of 6m, a height of 2m, and a length of 20-30m.

[0077] Put 2cm of fine sand in the greenhouse to make a sand bed, leave a 30cm wide...

Abstract

The invention discloses a method for the bickiron inoculation of buds symbiotic to root fungi for culturing the seedlings of Chinese chestnut. The method adopts the methods of the bickiron graft of bud seedlings and the root-pruning inoculation of root fungi for breeding the container seedlings of Chinese chestnut of which the root system is symbiotic to the root fungi, prior diluted Chinese chestnut mycorhiza liquid or a prior Chinese chestnut mycorhiza agent is adopted, and inoculation is carried out after root pruning; on one hand, side roots have flourishing growth; on the other hand, the root system is symbiotic to the root fungi, and then the container seedlings are transplanted into a greenhouse for large-scale culture; and the seedlings after being cultured successfully are directly transplanted into a plowland, the seedling raising time is quick, the survival rate of the seedlings is high, and the growth of the seedlings is robust.

Description

technical field [0001] The invention belongs to the field of nursery stock cultivation, and relates to a method for cultivating chestnut seedlings, in particular to a method for grafting and cultivating chestnut seedlings with rhizome symbiosis. Background technique [0002] Chestnut (Castanea mollissima Blume) claims again chestnut, wool chestnut, is the special product of my country. Traditional medicine believes that chestnut is warm in nature, sweet and flat in taste, enters the spleen, stomach, and kidney meridian, and has the effects of nourishing the kidney and strengthening the spleen. Li Shizhen of the Ming Dynasty recorded in "Compendium of Materia Medica": "Chestnut treats kidney deficiency, weakness of the waist and legs, can unblock the kidney and replenish qi, thicken the stomach, the kidney governs stool, and chestnut can govern the kidney." Tang Sun Simiao's "Thousand Gold Prescriptions" says: "Chestnuts, salty and warm, non-toxic, nourishing qi, thickening ...
