Problems solved by technology

[0002] At present, chestnut orchards are still planted directly in the field. This method usually leads to high seed rot rate, low emergence rate, slow seedling growth, low graftability rate, irregular garden appearance, and late fruiting period. and other issues, affecting the cultivation efficiency

Embodiment 1

[0033] ⑴ Germination: on April 22, 2014 (5 consecutive days, the average temperature throughout the day is 12 ℃). The seeds are chestnuts stored in cold storage, which are required to be basically the same size, free from rot and insects. After the seeds are taken out, they are naturally placed for 2 days, and then mixed with clean wet sand at a ratio of chestnut: wet sand=1:2 (volume ratio). The humidity of the wet sand is no water dripping, and the wet sand can be loosened slowly after the wet sand is gripped tightly by hand. When mixing chestnuts and wet sand, add a small amount of carbendazim to the wet sand, about 200g per cubic meter of sand, to prevent infection by fungal diseases. After mixing the chestnuts and wet sand, store them in a warm place outside and cover them with wet sacks. When the surface of the sand is dry, you can properly spray water on the sacks. Chestnut begins to germinate in about 8-10 days, and when the radicle grows to 0.5cm, cut off the growth...

Embodiment 2

[0040] ⑴The seeds are chestnuts stored in cold storage, which are required to be basically the same size, free from rot and insects. On April 22, 2014 (5 days in a row, the average temperature throughout the day was 12°C), the seeds were taken out and placed naturally for 2 days. Then soak the chestnut seeds with 25% carbendazim wettable powder 400 times liquid for 2 hours, take them out and dry them in the air.

[0041] ⑵ Preparation of nutrient soil: The nutrient soil is sandy loam and decomposed sheep manure, and the ratio of the two is loam: sheep manure = 4:1 (volume ratio). Before mixing, the sandy loam is sieved to remove stones and coarse sand. After the sandy loam is sieved, it is fully mixed with sheep manure, and the mixed nutrient soil is put into paper cups. The paper cups are commercially available, degrade within 2-3 months, thicken, and have a size of 20cm×16cm. After installation, the surface soil layer of the paper cup is required to be 2cm away from the m...

Embodiment 3

[0047] (1) Acceleration of germination: on April 22, 2014 (same as Example 1) (for 5 consecutive days, the average temperature throughout the day was 12°C day). The seeds are chestnuts stored in cold storage, which are required to be basically the same size, free from rot and insects. After the seeds are taken out, they are naturally placed for 2 days, and then mixed with clean wet sand at a ratio of chestnut: wet sand=1:2 (volume ratio). The humidity of the wet sand is no water dripping, and the wet sand can be loosened slowly after the wet sand is gripped tightly by hand. When mixing chestnuts and wet sand, add a small amount of carbendazim to the wet sand, about 200g per cubic meter of sand, to prevent infection by fungal diseases. After mixing the chestnuts and wet sand, store them in a warm place outside and cover them with wet sacks. When the surface of the sand is dry, you can properly spray water on the sacks. Chestnut begins to germinate in about 8-10 days, and when...

Abstract

The invention relates to a chestnut seedling cup cultivation technology and belongs to the technical field of seedling cultivation. The technology includes sowing chestnut seeds, after pregermination, to cups filled with soil; performing pregermination for 8 to 10 days at the daily average temperature ranging from 10 to 15 DEG C after mixing the chestnut seeds and wet sand at the volume ratio of 1 :2; during pregermination, when radicle grows till 0.5cm, removing the growth point by 0.1 to 0.2cm. According to the technology, the pregermination and sowing are performed in opened fields, and the seedling cultivation environment and the growth environment after transplantation are the same; after the transplantation, the survival rate is high, the slowness is avoided, and the growth tendency is fine. The technology is simple and easy to learn, the operability is high, the germination rate can be increased effectively, the germination is uniform, and farm appearance is neat; the seedling quality is high, and the grafting rate of one-year seedlings can be 96% above; the cups are adopted, the environment can be protected, and the chestnut root growth can benefited.

Description

technical field [0001] The invention relates to a technique for raising chestnut seedlings in paper cups, and belongs to the technical field of seedling raising. Background technique [0002] At present, chestnut orchards are still planted directly in the field. This method usually leads to high seed rot rate, low emergence rate, slow seedling growth, low graftability rate, irregular garden appearance, and late fruiting period. And other issues, affecting the cultivation efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a chestnut paper cup seedling raising technique which is different from direct sowing in the field. [0004] A paper cup seedling raising technique for chestnuts, comprising the step of sowing chestnut seeds in paper cups filled with soil after germinating; [0005] The germination: when the daily average temperature is 10-15 ° C, the chestnut seeds and wet sand are mixed according to the volume ratio of 1:2...
