Mountain german oak, cork oak biomass energy forest planting method

[0045] Example 1:

[0046]A method for afforestation of Quercus quercus and Quercus cork biomass energy forests in mountainous areas, selecting the excellent Quercus quercus and Quercus cork that are more than 15 years old with strong direct dryness and robust growth as the seed-collecting forest, and collecting the seeds of Quercus quercena and Quercus cork in September seed. On the day when the seeds were collected, soak the Quercus quercus seeds or Quercus cork seeds with 15% Camellia oleifera bran water for 30 minutes to kill insects and weevil; spread the Quercus hemp and Quercus cork seeds after the insecticidal treatment. In a cool place, the dried seeds are used for seedling afforestation.

[0047] In the areas where the freezing is not severe in winter, the seedlings should be cultivated within 3 days of seed treatment; in the areas with severe freezing, the seeds should be stored in layers with fresh, clean and moist river sand.

[0048] The concrete operation method of described strong seedling cultivation is as follows:

[0049] Choose sandy loam soil and light loam soil with flat terrain, good drainage and irrigation conditions as seedling beds, and plough and harrow the ground. Use fresh, clean and moist river sand for germination in sand storage, keep the river sand moist, keep the temperature at 18-26°C, cut off the root tips when the germ grows 2-3cm, and then move it to a 8×12cm room with a matrix. Planting in a non-woven container bag, obtaining container seedlings of Quercus quercus and Quercus cork container; wherein, the preparation method of the substrate is to excavate aseptic loess soil, pulverize and sieve, and mix in 3% calcium superphosphate with a weight concentration of 3%. Base fertilizer, made by mixing evenly. Place the container seedlings of Quercus oak and the container seedlings of Quercus cork on the nursery bed with 25 rows of each border evenly and close to each other. The borders are spaced by 30 cm of footpaths. The edge of the border is covered with soil to the same height as the non-woven container bag. After one year of protection, the nursery will be planted.

[0050] The concrete operation method of described seedling afforestation is as follows:

[0051] Select the plots with good site conditions, thick soil layers, and high survival rate of afforestation for planting seedlings; 25 days before afforestation, according to the plant-row spacing of 1 × 1.5m, the length, width and depth of 40 × 40 × 30 cm specifications, dig pits for soil preparation , and fill the pit and cover with soil; in the rainy seasons of autumn and winter, choose the oak oak container seedlings and cork oak container seedlings that grow robustly, have no branches, no pests and diseases, annual, soaked water, and plant them in the center of the afforestation pit preparation. For a planting pit of the same width and depth, vertically place the container seedlings of oak oak and the container seedlings of oak cork into the planting pit, cover the soil for 2-3 times and step on it, then cover with a layer of loose soil, and cover the surrounding area with weeds.

[0052] After planting seedlings, weeding and soil loosening are mainly done; the time for weeding and soil loosening is three years after planting seedlings and afforestation, and weeding and soil loosening are carried out twice a year. The first weeding and soil loosening time is from May to June, and the second time The time of weeding and loosening is from September to November; the method of weeding is to remove tall grass and vines, and cut down saplings with poor growth, low branches or damage by diseases and insect pests within 5 cm above the level ground to cultivate their buds Growth; the method of loosening the soil is to loosen the soil in a range of 50 cm around the planting pit.

[0053] When the young forest is 8-10 years old after planting, some plants have a diameter of more than 8cm at breast height and a tree height of more than 7m, that is, they have reached the technological maturity stage, and can be used according to 30% of the number of preserved plants. Within the range of 5 cm, 30% of the number of preserved plants will be selected and cut once every three years. At the same time, the trees with poor growth and those damaged by diseases and insect pests will be cut down. The tail diameter of 4 cm or more is used for centralized charcoal burning and thermal power generation, and the branches and forks below 4 cm are used. In the cultivation of mushrooms, fungus and other edible fungi.

[0054] This method is also used for replanting and tending transformation of existing inferior and low-efficiency forests.

[0055] Example 2:

[0056] A method for afforestation of Quercus quercus and Quercus cork biomass energy forests in mountainous areas, selecting the excellent Quercus quercus and Quercus cork trees that are more than 15 years old with strong direct drying and robust growth as the seed-collecting forest, and collecting the seeds of Quercus quercena and Quercus cork in October seed. On the day when the seeds were collected, soak the Quercus quercus seeds or Quercus cork seeds with 15% Camellia oleifera bran water for 30 minutes to kill insects and weevil; spread the Quercus hemp and Quercus cork seeds after the insecticidal treatment. In a cool place, the dried seeds are used for seedling afforestation.

[0057] In areas with less severe freezing in winter, the seedlings should be cultivated within 5 days of seed treatment; in areas with severe freezing, the seeds should be stored in layers with fresh, clean and moist river sand, and the seedlings should be cultivated after the soil is thawed in spring.

[0058] The concrete operation method of described strong seedling cultivation is as follows:

[0059] Choose sandy loam soil and light loam soil with flat terrain, good drainage and irrigation conditions as seedling beds, and plough and harrow the ground. Carry out germination in sand directly on the border surface, cut off the root tip when the germ grows 2-3 cm, and then move it to a non-woven container bag with a size of 8 × 12 cm with matrix for planting to obtain the container seedlings and Quercus cork container seedlings; wherein, the preparation method of the substrate is to excavate sterile yellow loam soil, crush and sieve, mix in superphosphate base fertilizer with a weight concentration of 5%, and mix evenly to prepare. Place the container seedlings of Quercus hemp and Quercus cork on the nursery bed, evenly and close to each other in 30 rows, with 40 cm intervals between the borders, and the edge of the border is covered with soil to the same height as the non-woven container bag, and the container seedlings are sprayed with water and weeding pipes. After one year of protection, the nursery will be planted.

[0060] The concrete operation method of described seedling afforestation is as follows:

[0061] Select the plots with good site conditions, thick soil layers and high survival rate of afforestation for planting seedlings; 45 days before afforestation, according to the plant-row spacing of 1 × 1.5m, the length, width and depth of 40 × 40 × 30 cm specifications, dig pits for soil preparation , and fill the pit and cover with soil; in the rainy seasons of autumn and winter, choose the oak oak container seedlings and cork oak container seedlings that grow robustly, have no branches, no pests and diseases, annual, soaked water, and plant them in the center of the afforestation pit preparation. For a planting pit of the same width and depth, vertically place the container seedlings of oak oak and the container seedlings of oak cork into the planting pit, cover the soil for 2-3 times and step on it, then cover with a layer of loose soil, and cover the surrounding area with weeds.

[0062] After planting seedlings, weeding and soil loosening are mainly done; the time for weeding and soil loosening is three years after seedling planting and afforestation. Weeding and soil loosening are carried out twice a year. The soil loosening time is in November; the weeding method is to remove tall grass and vines, and cut down the saplings with poor growth, low branches or damage by diseases and insect pests within 5 cm above the level ground to cultivate their budding growth; The method is to loosen the soil in a range of 50 cm around the planting pit.

[0063] When the young forest is 8-10 years old after planting, some plants have a diameter of more than 8cm at breast height and a tree height of more than 7m, that is, they have reached the technological maturity stage, and can be used according to 30% of the number of preserved plants. Within the range of 5 cm, 30% of the number of preserved plants will be selected and cut once every three years. At the same time, the trees with poor growth and those damaged by diseases and insect pests will be cut down. The tail diameter of 4 cm or more is used for centralized charcoal burning and thermal power generation, and the branches and forks below 4 cm are used. In the cultivation of mushrooms, fungus and other edible fungi.

[0064] This method is also used for replanting and tending transformation of existing inferior and low-efficiency forests.

[0065] Example 3:

[0066] A method for afforestation of Quercus quercus and Quercus cork biomass energy forests in mountainous areas, selecting the excellent Quercus quercus and Quercus cork that are more than 15 years old with strong direct dryness and robust growth as the seed-collecting forest, and collecting the seeds of Quercus quercena and Quercus cork in September seed. On the day when the seeds are collected, soak the Quercus quercus seeds or Quercus cork seeds with 15% Camellia oleifera bran water for 30 minutes to kill the weevil; spread the Quercus quercus seeds and Quercus cork seeds after the insecticidal treatment in a cool place , the dried seeds are used for direct seeding afforestation.

[0067] In areas with less severe freezing in winter, the seeds are sown in the planting pits for direct seeding afforestation on the day of seed treatment; in areas with severe freezing, fresh, clean and moist river sand is used to stratify the seeds for germination, and then the soil is thawed in spring before direct seeding afforestation. .

[0068] The concrete operation method of described seedling afforestation is as follows:

[0069] Select the dry barren and rocky desertification planting seedlings with low survival rate or difficult to survive as the direct seeding afforestation. Thirty days before the seeds are harvested, according to the plant-row spacing of 1×1.5m, and the length, width and depth of 40×40×30cm, dig the planting pit for soil preparation, and fill the pit with soil.

[0070] Put 3-4 seeds of Quercus hemp and Quercus cork after insecticidal treatment, lay horizontally in triangle or square, cover soil 2-3 cm, and cover weeds without seeds. In the four years after direct seeding, weeding and loosening the soil twice a year. The first weeding and soil loosening is from May to June, and the second weeding and soil loosening is from September to November. The weeding method is to remove tall grass and soil. For vines, cut down young trees with poor growth, low branches or damage by diseases and insect pests within 5cm above the level ground to cultivate their budding growth; the method of loosening the soil is to loosen the soil within a range of 50cm around the planting pit;

[0071] When the young forest is 8-10 years old after planting, some plants have a diameter of more than 8cm at breast height and a tree height of more than 7m, that is, they have reached the technological maturity stage, and can be used according to 30% of the number of preserved plants. Within the range of 5 cm, 30% of the number of preserved plants will be selected and cut once every three years.
