Embodiment 1
[0058] The purpose of the present embodiment is to provide a method for afforestation of chestnut large-scale breeding, comprising the following steps:
[0059] Seed treatment: select chestnut seeds with full grains, no cracks and no pests, and mix them with plant ash, coarse sand and fine sand. The mass ratio of plant ash, coarse sand and fine sand is 1:12:8. Sand storage after the mixing is completed. And after sand storage, take out and screen to obtain planting seeds; the temperature of sand storage is 6°C-10°C, the relative humidity of sand storage is 30%-40%, and after sand storage, at an ambient temperature of 15°C-20°C Take out the filter.
[0060] Seedling raising: Soak the seeds in disinfectant for 3 hours, then dry them; choose well-drained, sunny sandy loam and light loam as the seedling land, and seal the seeds for germination at 20°C and a relative humidity of 25%. When the height of the seedlings reaches 2cm-3cm, the seedlings are planted in the nursery field, ...

[0064] The purpose of the present embodiment is to provide a method for afforestation of chestnut large-scale breeding, comprising the following steps:
[0065] Seed treatment: select chestnut seeds with full grains, no cracks and no pests, and mix them with plant ash, coarse sand and fine sand. The mass ratio of plant ash, coarse sand and fine sand is 1:15:9. Sand storage after the mixing is completed. And after sand storage, take out and screen to obtain planting seeds; the temperature of sand storage is 6°C-10°C, the relative humidity of sand storage is 30%-40%, and after sand storage, at an ambient temperature of 15°C-20°C Take out the filter.
[0066] Seedling raising: Soak the planting seeds in the disinfectant solution for 2 hours, and then dry them; choose well-drained, sunny sandy loam, light loam as the seedling breeding ground, and seal the planting seeds at 15°C and a relative humidity of 20%. When the height of the seedlings reaches 2cm-3cm, the seedlings are pla...
Embodiment 3
[0070] The purpose of the present embodiment is to provide a method for afforestation of chestnut large-scale breeding, comprising the following steps:
[0071] Seed treatment: select chestnut seeds with full particles, no cracks and no pests, and mix them with plant ash, coarse sand and fine sand. The mass ratio of plant ash, coarse sand and fine sand is 1:10:7. After the mixing is completed, carry out sand storage. And after sand storage, take out and screen to obtain planting seeds; the temperature of sand storage is 6°C-10°C, the relative humidity of sand storage is 30%-40%, and after sand storage, at an ambient temperature of 15°C-20°C Take out the filter.
[0072] Seedling raising: Soak the planting seeds in the disinfectant solution for 4 hours, and then dry them; choose well-drained, sunny sandy loam, light loam as the seedling raising ground, and seal the planting seeds at 25°C and 30% relative humidity for germination. When the height of the seedlings reaches 2cm-3c...
