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, ...

Embodiment 2

[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...

Abstract

The invention provides a large-scale breeding and afforestation method for Chinese chestnuts, and relates to the technical field of forest cultivation. The breeding and afforestation method comprises the four stages of seed treatment, seedling raising, transplanting and young forest management for large-scale breeding and afforestation. According to the breeding and afforestation method, planting seeds with the high survival rate are obtained by selecting the seeds and conducting sand storage with the plant ash, the coarse sand and the fine sand, planting is conducted after disinfection and germination acceleration are conducted, seedlings are cultivated, and at the moment, the growth condition of the seedlings is good. The cultivated seedlings are transplanted to a land parcel with the relative humidity of 25%-30%, the plant spacing is 2 m * 2 m, and it is avoided that the chestnut trees shield each other in the growth process, and the photosynthesis of the chestnut trees is affected. After the seedlings grow in the adaptive period, regular watering, fertilization, impurity removal, soil loosening and pest management are conducted on the seedlings, so that the seedlings grow healthily to be adult, and then the effect of increasing the yield is achieved.

Description

technical field [0001] The invention relates to the technical field of tree cultivation, in particular to a large-scale breeding and afforestation method for chestnuts. Background technique [0002] Chestnut is also known as chestnut, hair chestnut, wind chestnut, cone chestnut and Kui chestnut. In addition to being rich in starch, it is also rich in monosaccharides, disaccharides, carotene, thiamine, riboflavin, niacin, ascorbic acid , protein, fat, inorganic salts and other nutrients. It can not only be eaten raw or cooked, but also can be processed into canned chestnut chicken, chestnut soup, chestnut preserves and other flavor foods, and can also be made into cakes of various tastes. It can be seen that while the edible value of chestnut is higher, the economic value is higher, therefore, large-scale planting and breeding have greater economic value. [0003] However, when the chestnut is planted, the seedlings do not grow well, so that the production status of the che...
