Viveros Forestales - Test 11

• Abonos orgánicos: Applied based on plant nutritional requirements; a foliar analysis is one method. Excessive application can negatively affect plants by promoting damping-off. Optimal organic matter content is between 2% and 4%.

• Mineral Fertilizers: Purpose is to promote overall plant growth and encourage root development for better anchoring.

• Seedling Depth: For a 0.5 centimeter (cm) diameter seed, the ideal planting depth is 1 cm.

• Pinus Radiata Planting Season: Suitable planting time is in October, not in March, November, or June.

• Sprinkler Irrigation: Benefits include less water consumption and lower installation costs; good for precise water distribution, and good for plants.

• Weed Control / Herbicides: Total herbicides are used to eliminate weeds, preferably before seed germination and are not typically used on forested areas.

• Repotting (Repicado): Stimulates root development and delays aerial growth.

• Repotting Quercus Petrea: Repotting depth is 10 to 15 cm, and post-repoting, irrigation is essential.

• Conifer Repotting: Timing can be early or late and depends on the species.

• Sandy Soil: A concern related to root-ball extraction and extraction through mechanical methods.

• Damping-off: A fungal disease that can affect seedlings and is a consequence of issues with organic fertilizers or soil pH issues.

• Aviveramiento (Nursery): The goal is to increase the time span between the extraction process and planting time in the field. This method promotes the growth of the plant's root system.

• Advantages of Bare-root Plants: Compared to container-grown plants, bare-root plants are easier to handle in the forest.

• Organic Fertilizer Application: Timing of application is crucial for optimal growth. Don't use them during planting.

• Plant Spacing (Pinus radiata): For planting in parallel rows, space should be between 10 and 15 cm.

• Planting Depth (Seedling Diameter): For a seed with a maximal diameter of 6 mm, the planting depth must be 12 mm.

• Quercus Robur Planting: The appropriate planting time is between late winter and early spring.

• Irrigation for Root-ball Damage: Certain irrigation methods, such as sprinkler irrigation, may increase the chance of forming soil crusts near the base of the roots.

• Repotting Recommendations: Repotting depths should generally fall between 20-30 cm. The objective behind repotting is to slow down aerial growth. Watering immediately after repotting is not recommended.

• Root Nematode Treatment: Best time for treatment is between planting and seedling emergence.

• Plant Acceptance Rate: Max 10% of plants can be considered unacceptable/defective.

• Nursery Purposes: Used for both bare-root and container-grown plants; it extends the time before planting in the field.
