Cultivation Methods and Precautions for Spruce Trees
This article offers tips and techniques for cultivating spruce trees, including small-scale domestic cultivation experiences. The following introduction is provided by the site editor for netizens.
Spruce trees are unique to China and are also known as the Mao County Spruce. They mainly grow in Shaanxi Province, Gansu Province, and the Bai龙江 River Basin. These areas have an average altitude of over 2000 meters, with dry and cold conditions suitable for their growth. These trees are tall with few branches, and their grain is uniform and fine. This article mainly analyzes the management and cultivation techniques of spruce trees.
Spruce trees are unique to China, with straight trunks, uniform and beautiful grain, easy to process, and possess considerable economic value. They can also be used as potted plants for ornamental purposes. Nowadays, spruce trees are widely used in forestation projects in China. Due to their strong ornamental value, they are extensively utilized in urban landscape design. Given the wide use of spruce trees in daily life, China has made rapid progress in their cultivation and management, enhancing their economic and ornamental value. To cultivate high-quality spruce varieties, it is necessary to provide a suitable growing environment and continuously improve cultivation techniques.
1 Spruce Seedling and Seed Selection
1.1 Choosing Spruce Seedling Sites and Seeds
Spruce trees are cold-tolerant, shade-tolerant, and drought-resistant, with shallow root systems, generally suitable for planting in sandy soil. Therefore, when selecting spruce planting sites, it is important to choose well-drained sandy soil for seedling sites to benefit the growth of spruce seedlings. Before sowing, seeds must be selected, using methods such as water or wind selection to choose plumper seeds. Then, the seeds are soaked in ferric sulfate solution until they turn black, followed by placing them in warm water to induce germination until the seeds crack open before sowing.
1.2 Spruce Sowing
Spruce sowing is usually done in mid-April. Sowing at this time can improve the germination rate of spruce and reduce the cost of seedling care. On a windless day, ensure the distance between seeds and the space between ridges and beds. After sowing, use a mixture of sandy soil and sawdust to evenly cover the soil, improving its permeability and aeration.
1.3 Management of Spruce Seedlings
Since spruce trees are shade-tolerant, it is essential to provide shading and prevent excessive shade for spruce seedlings. Ensure regular and measured sunlight for their growth. Pay attention to disease prevention during the seedling stage and be prepared for sudden temperature drops and drought conditions to effectively improve the survival rate of spruce seedlings.
Cultivation Methods and Precautions for Spruce Trees
2 Spruce Transplanting
2.1 Methods of Transplanting Spruce
Spruce trees have very shallow root systems, so transplantation is usually done with soil. Excavate around the root system according to the growth characteristics of spruce roots, then use moist grass ropes to tie the soil ball and roots. The tying should not be too tight or too loose to avoid root damage and reduce the survival rate of transplanted spruce.
2.2 Moderate Pruning
Regular pruning of spruce seedlings not only reduces water loss during transportation but also improves the survival rate of spruce seedlings and their ornamental value. When pruning, start from the bottom and work upwards, ensuring that the growth and appearance of the spruce are not affected.
2.3 Packaging and Transportation of Spruce
Due to the shallow roots of spruce, they can be easily damaged during packaging and transportation, reducing the survival rate. Effective management is required during these stages. Use grass ropes and grass sheets to wrap the roots of the spruce and ensure moisture during transportation, especially during long-distance transport. Stop along the way to water the spruce in shaded areas to ensure sufficient moisture.
3 Management of Spruce Planting
3.1 Planting Spruce Trees
Spruce trees should be planted at the right time, usually on windless and overcast days. Avoid planting during high temperatures. When planting spruce, pay attention to the distance between seedlings and plant according to the requirements. Ensure that the seedlings are upright and stable. In addition to the distance between seedlings, pay attention to the depth of planting. Thoroughly water the soil after the first watering, then water again after one or two days when the soil settlement cracks appear, tamping the soil to make sure the roots are in full contact with the soil and can absorb moisture effectively.
