Example Embodiment

[0020] Example 1

[0021] A method for cultivating thin-shell pecan nutrient bag seedlings includes the following steps:

[0022] (1) Mix 4kg of perlite, 11kg of wood chips, 1kg of slow fertilization and 2kg of field mud to obtain a substrate;

[0023] (2) Fill the seedbed with water, add sterilization and insecticide in the water, put the substrate in a nutrient bag and soak in the water of the seedbed for 3 days, take out and remove the water to a relative humidity of 45-55;

[0024] (3) Select pecan seeds with good quality harvested that year, soak pecan seeds with 400ppm gibberellin for 5-8 days, and store the soaked seeds in sand for 6-8 days;

[0025] (4) Sow the sand-stored seeds into a nutrient bag, cover with arch film, and the temperature of the seed position does not exceed 48 degrees. When the emergence rate reaches 45% to 50%, remove the arch in the morning or evening when the temperature is low. After removing the arching film, watering, weeding, spraying, and fertilizing...

[0029] Example 2

[0030] A method for cultivating thin-shell pecan nutrient bag seedlings includes the following steps:

[0031] (1) Mix 5kg of perlite, 9kg of wood chips, 1kg of slow fertilization and 4kg of field mud to obtain a substrate;

[0032] (2) Fill the seedbed with water, add sterilization and insecticide in the water, put the substrate in a nutrient bag and soak in the water of the seedbed for 3 days, take out and remove the water to a relative humidity of 45-55;

[0033] (3) Select pecan seeds with good quality harvested that year, soak pecan seeds with 400ppm gibberellin for 5 days, and store the soaked seeds in sand for 8 days;

[0034] (4) Sow the sand-stored seeds into a nutrient bag and cover with arch film. The temperature of the seed part should not exceed 48 degrees. When the seedling rate reaches 45%, remove the arch film in the morning or evening when the temperature is low. After filming, watering, weeding, spraying, and fertilizing are carried out. When the gr...

[0038] Example 3

[0039] A method for cultivating thin-shell pecan nutrient bag seedlings includes the following steps:

[0040] (1) Mix 6kg of perlite, 10kg of wood chips, 1kg of slow fertilization and 3kg of field mud to obtain a substrate;

[0041] (2) Fill the seedbed with water, add sterilization and insecticide in the water, put the substrate in a nutrient bag and soak in the water of the seedbed for 3 days, take out and remove the water to a relative humidity of 50;

[0042] (3) Select pecan seeds with good quality harvested that year, soak pecan seeds with 400ppm gibberellin for 8 days, and store the soaked seeds in sand for 7 days;

[0043] (4) Sow the sand-stored seeds into a nutrient bag, and cover with arch film. The temperature of the seed part does not exceed 48 degrees. When the emergence rate reaches 50%, remove the arch film in the morning or evening when the temperature is low. After filming, watering, weeding, spraying, and fertilizing are carried out.

Abstract

The invention provides a carya illinoensis nutrition bag seedling cultivation method. The method includes: mixing perlite, wood flour, slow release fertilizer and field mud according to a mass ratio of (4-5):(9-11):1:(2-4) to obtain a matrix, removing water to keep the relative humidity of 45-55 after the matrix is subjected to sterilization and deinsectization in water, soaking carya illinoensis seeds in gibberellin with the concentration of 400ppm for 5-8 days, storing the soaked seeds in sand for 6-8 days, then sowing the seeds stored in sand into a nutrition bag and covering the nutrition bag with arched film, removing the arched film when the rate of emergence reaches 45%-50%, watering, weeding, spraying insecticide and fertilizing after the arched film is removed, and grafting after the ground diameter of nursery stocks reaches more than 0.4cm. Cultivated carya illinoensis nutrition bag seedlings are complete in roots, survival rate of afforestation is high, land for seedling cultivation can be effectively saved, and seedling cultivation period is shortened, so that seedling cultivation cost is reduced, annual seedling cultivation can be realized, and seedling cultivation scale is larger.

Description

technical field [0001] The invention belongs to the technical field of seedling cultivation, and in particular relates to a method for cultivating thin-shell hickory nut nutrition bag seedlings. Background technique [0002] Thin-shelled hickory has well-developed taproots and fewer lateral fibrous roots. The afforestation survival rate of bare-root thin-shelled hickory seedlings is only 20% to 40%, and the survival rate of thin-shelled hickory nut seedlings in nutritional bags can be increased by more than 40% compared with bare-rooted seedlings in winter and spring, and can be used for annual afforestation. But for now, also do not have a kind of method that can cultivate thin-shell hickory nut nutrition bag seedlings on a large scale. Contents of the invention [0003] The object of the present invention is to provide a method for cultivating nutrient bag seedlings of pecan with thin shells, aiming at solving the problem that the existing nutrient bag seedlings of peca...
