Technical explanation of non-woven container seedlings in seedling selection, land preparation, afforestation methods, etc.

The advantages of the non-woven container seedling afforestation method are mainly good air permeability, not easy to fall off, the growth of seedling roots and soil contact weight, low cost, easy to transport, less soil pollution, non-woven container seedling planting, container bag according to the seedling The size, suitable site conditions for the planting area, transportation distance, and specific small supplements will be detailed below. 1. Choose seedlings 1. Choose suitable seedlings according to afforestation requirements. Choose seedlings with complete containers, vigorous growth, no mechanical damage, no pests, and well-developed roots. 2. If the seedlings cannot be transported to the mountain for planting in a short time, they can be planted near the woodland. The planting place should be sheltered from the wind, facing the sun, and the terrain should be flat to facilitate the collection of soil, water and transportation of seedlings. Second, site preparation According to the local site conditions, adopt the fish-scale pit mixed preparation method, which is appropriately large and appropriately small. For woodlands with thick soil layers, gentle slopes and low soil erosion, large holes are used to fill the land. For woodlands with complex terrain, large slopes and poor site conditions, small holes are used for site preparation. Mixed land preparation can make full use of forest land. 3. Tree planting and afforestation Afforestation can be carried out through land preparation and direct seeding afforestation, as follows: 1. Prepare afforestation and afforestation in time. Direct seeding afforestation is planting while preparing the land. Direct seeding afforestation combines the two processes of land preparation and planting, which can save planting time and reduce labor intensity. Advantages of direct seeding afforestation: Direct seeding afforestation avoids spring drought and busy agricultural production in the rainy season; in the rainy season, the soil is soft, which is conducive to land preparation. Small fish scales (50cm×50cm×30cm or 30cm×30cm) are used for direct seeding afforestation. They have good moisture and drought resistance, can prevent water loss, and have a high survival rate. The seedlings are not easy to be chewed by the hare, which can reduce the rabbit's damage. Disadvantages of small hole direct seeding afforestation: seedlings are easily covered by shrubs and weeds after they survive. Therefore, in the second year of planting, management should be strengthened, and holes should be expanded, cut and irrigated in time. 3. Planting For planting, the site should be prepared and dig in a good place. The hole should be neat and upright, and the soil should be as little broken as possible. The bottom of the seedling bag should be broken or torn off, and then placed vertically into the hole. 4. The best time for planting From late June to early August. 5. Management, timely removal of shrubs and weeds that affect the growth of seedlings; serious seedling holes on the ridge and sides of the rabbit, use a branch tip refuge to reduce the damage to the rabbit.
