Seedling raising technique of Picea koraiensis
Purple fruit spruce (PiceapurpureaMast), commonly known as iron pine, is a tall coniferous tree, which likes wet, cold and dry climate, and the young forest has strong shade tolerance. Mainly distributed in Qinghai, Sichuan and Gansu. It is widely distributed in the shady slopes, semi-shady slopes and river valleys of the Bailong River forest region, Taohe forest region and Daxia River forest region at an altitude of 2800-3600m above sea level in Gannan, forming a unique forest landscape in high mountains. It plays an important role in conserving water sources and preventing soil erosion. At the same time, it is one of the excellent native tree species.

Metasequoia glyptostroboides, a precious relict tree species
Scientific name: Metasequoaglyptostroboides family genus: Taxodiaceae, Metasequoia deciduous trees, precious relict plants in China. Metasequoia glyptostroboides has the advantages of rapid growth, strong adaptability, straight stem, less diseases and insect pests and so on. Wood is light and easy to process, but its strength is weak and it is not resistant to decay, so it can be used for construction, furniture, papermaking and so on. Metasequoia glyptostroboides has strong cold resistance, which requires moist soil and can grow in light saline-alkali soil. Huge tall and straight, luxuriant branches and leaves, changeable leaf color, suitable for concentrated afforestation or cluster planting.

How to control metasequoia red blight?
Prevention and control methods of red blight of Metasequoia glyptostroboides: first, plant quarantine should be strictly carried out, diseased seedlings should be prohibited from being introduced into new areas, and diseased seedlings should be cleared and burned immediately. Second, the water for planting seedlings should be too dense. It is required to be ventilated and transparent, reduce the humidity in the air, increase the application of phosphorus and potassium fertilizer, and apply less nitrogen fertilizer to promote the healthy growth of seedlings and improve the ability of disease resistance. 3. During April to May and September to October, Bordeaux solution or 50% carbendazim wettable powder or 50% carbendazim wettable powder can be sprayed in a ratio of 1: 1 to 200 times or 50% to 1000 times.

spruce seedling transplanting method
According to the geographical location and climatic characteristics of the afforestation site, select the microclimate conditions suitable for spruce growth, especially the wet conditions. Under suitable microclimate conditions, we should focus on selecting soil with deep soil layer, loose texture and rich organic matter. In places with poor site conditions and less vegetation, we should strengthen cultivation measures to improve soil fertility. In order to ensure the shade tolerance and moisture tolerance needed for spruce growth, the traditional seedling planting method was changed in our farm in Wulasitai Township in 2002. The seedlings with height above 50 cm were selected and the holes were dug 40×40×

spruce blight
[Distribution and harm] The disease occurred in Songhua River area and Yichun forest area of Heilongjiang Province, damaging Picea koraiensis 16~21-year-old plantation. In the damaged stand, the young trees of Abiesnephrolepis and Pinus koraiensis, which were naturally regenerated, were also infected. A felt hyphae layer grows on branches and leaves, causing wilting and felting. Spread upward from the lower part of the canopy and taper along the trunk.

Techniques of Spruce Seedling
Spruce is a pine spruce, evergreen trees, up to 30 meters high, is the main species of mountain forests in our region. Spruce wood is soft and delicate, which can be used for construction, furniture, papermaking and other materials, as well as ornamental trees. A, cuttage seedling cuttage time should be in early spring after taking out new shoots, cut 15 cm long cuttings, cuttage in the plastic shed. In order to increase the ground temperature, the bottom of the bed can be padded with horse manure, keep the ground temperature at 25-35℃, and the humidity is about 90%. The plastic shed should be covered tightly and should not be opened frequently to avoid lowering.

Cone-shaped things on young spruce trees-- control of larch ball aphids
On the young trees of spruce, a round shape similar to a small cone often appears in June, which is actually a gall caused by larch aphid. In order to complete a life cycle, larch aphids need to undergo several different insect type changes in spruce and larch trees. Its life process can be seen in 156. What is the white hair on the leaves of larch? Artificial removal of galls from spruce before galls crack. Strengthen preventive measures to prevent the transportation and afforestation of seedlings with insects. Spruce and larch cannot be mixed or planted closely, isolated from each other.

Spruce bud rust
Spruce bud rust is a newly discovered disease in the northern forest region of China, which has been reported in the natural forest region of Xing'an Mountains. It is mainly distributed in the United States, Canada, Sweden and other countries abroad, harming white spruce, black spruce and European spruce, harming the terminal and lateral buds of seedlings, young trees and big trees, and seriously affecting the quality of seedlings and the normal growth of plantations. Symptoms appear when new leaves begin to grow in late May. During the same period, diseased buds grew faster and longer than healthy buds, but soon stopped growing. Diseased leaves growing from diseased buds

Spruce snow mildew
[distribution and harm] the disease occurs in North America, Northern Europe, Japan and other countries, harming fir (Abies), spruce (Picea), willow (Cryptomeriafortunei) and other tree species. In China, it is distributed in forest areas such as western Tianshan, western Junggar and Altai Mountains. The main affected areas are Gongliu, Yining, Tacheng and other places. Seriously ill nursery, the annual loss rate is 330.62%. In artificial regeneration of young forests, the disease is also very serious, especially with seedlings, weak seedlings and bands.

Control of snow blight of spruce
Snow blight harms spruce needles, which are reddish brown. Snow blight occurs under snow. Ascospores invade spruce needles covered with snow. After maturing from September to October every year, it spreads with the help of wind and Rain Water. It was observed that in the young forest after artificial reforestation, because of the high planting density in the past, the situation of "hand in hand" was formed. once the disease spread particularly seriously, 1/2 of the needles of the plant were infected and lost green and turned reddish brown, resulting in the death of the whole plant. The unclosed regeneration land of Tex Forest Farm is nearly 2666 hectares, in order to ensure that
