If planting in arid areas, sufficient organic fertilizer needs to be applied in advance to ensure the nutrition of the saplings.

2. Seedling-stage management of Pinus sylvestris var. mongolica

During the early stage of seedling growth, the principle of small amounts and frequent irrigation should be followed when watering. During the rapid growth period in July-August, apply 1 thorough watering every 3-5 days. After mid-to-late August, in order to promote lignification of the seedlings and help them overwinter smoothly, watering is generally not carried out. Topdressing should be done during the vigorous growth period of the seedlings. In mid-July, thin out the overly dense and weak small seedlings. Loosen the soil in July-August, and promptly control pests and diseases.

Seedlings more than 2 years old need to be transplanted, which is done in early April in spring. When planting, the depth should be such that the seedling leaves are not buried in the soil. After planting, firm the soil and water promptly. After the transplanted seedlings survive, manage them in a timely manner to promote growth and cultivate them into specification-grade seedlings.

When planting Pinus sylvestris var. mongolica, it can be mixed in belts with larch and Siberian apricot, and mixed between rows or between plants with Ningtiao and sea buckthorn; in sandy land it can be mixed in belts or irregularly with elm; mixed between rows, in belts, or irregularly with shrubs; Pinus sylvestris var. mongolica can also be comprehensively mixed with broadleaf trees and shrubs to form mixed forests or forest belts combining conifers and broadleaves, and trees and shrubs.
