Seedling raising technique of softwood cuttings of European spruce
European spruce is an excellent tree species introduced from northern Europe in China. The tree grows fast. Because of its straight stem shape, wide adaptability, especially strong cold resistance, it has become not only an excellent timber tree species, but also an ornamental tree species for urban greening because of its beautiful tree shape and dense evergreen branches. Due to the direct introduction of seeds, the seedling growth is slow, it takes 5 years to get out of the nursery, and a large amount of foreign exchange is needed to introduce seeds, so the development is very slow. In order to speed up the promotion of this tree species and meet the needs of rapid development of forestry construction and urban and rural greening, I

Cultivation and afforestation techniques of Picea koraiensis
Picea koraiensis is shade-tolerant, drought-resistant, cold-resistant and fast-growing. It is not only the main tree species in the forest from Changbai Mountain to Xiaoxinganling in Northeast China, but also a common garden seedling. The cultivation and afforestation techniques of Picea koraiensis are introduced below. Breeding of improved varieties 1. Select a good stubble. Pinus sylvestris var. mongolica and larch stubble are suitable for red-bark spruce sowing land. for the bed stubble of these two kinds of trees, if the working area is small and the stubble can not be adjusted, a large amount of organic fertilizer and base fertilizer should be applied and disinfected carefully. Second, seed sprouting. Snow storage is the best treatment.

Seed collection, budding and seedling raising techniques of Picea koraiensis
Red skin spruce (PiceakoraiensisNakai), alias red skin smelly and white pine, is an important timber forest tree species and landscaping tree species in China. It is mainly distributed in Xiaoxing'an Mountains, Zhang Guangcai Mountains and Changbai Mountains, and a small amount is also distributed along the river valleys in the east and north of Daxing'an Mountains. 1 Biological characteristics and economic value of Picea koraiensis is a large evergreen tree with dense branches and leaves, strong shade and cold tolerance, slightly saline-alkali and drought tolerance. It is a shallow-rooted tree species, which is easy to be blown down by the wind and has a higher requirement for soil quality.

Transplantation of Picea koraiensis trees
Red spruce, alias tiger tail pine, Korean spruce, etc., is an evergreen tree of Pinaceae spruce. Originating in Northeast China and Korea, it is widely planted in Beijing and Qingdao, as well as in Northwest China. The tree species has graceful posture, steeple-shaped crown, spreading or slightly oblique branches, strong adaptability, shallow root distribution, well-developed lateral roots, and easy to survive after transplantation. 1. The best time for transplanting big trees is spring. Under the condition of perfect technical measures, the survival rate can reach more than 98% after transplantation in late November and late May. II. Transplant accuracy

Picea koraiensis: management techniques at seedling stage
(1) shading: red spruce seedlings like shade and dampness. after the seedlings are unearthed, the seedling preservation rate of proper shading is 30% 40% higher than that of full-light seedlings, the seedling height increases by 32%, and the tender leaves are bright green. Generally, when 50% of the seedlings emerge, they begin to set up day-covering curtains to cover the shade until they are removed in the early and middle of July. If it is difficult to cover and obtain materials, you can also plant tall crops (such as corn) along the bed instead of Reed curtains. In some areas, there are sufficient water sources and convenient irrigation. Watering with a small amount of water 2 or 4 times a day and mastering timely and appropriate watering can also make full-light seedling cultivation successful. (2) topdressing

Sagittarius sagittarius
Before seed collection, select high-yield fields with pure varieties, strong growth, light diseases and insect pests, and few flowering plants. Harvest when the upper part of the ground is completely dead. After harvest, the corms conforming to the characteristics of the variety, larger, heavier and more curved terminal buds are selected as seeds. Because the terminal bud is bent, it is beneficial to accumulate nutrients and is not easy to germinate. The terminal buds of the selected seed balls should be broken off, and a part of the upper part of the bulb should be taken slightly, that is, the terminal buds of the arrowhead should be poured, soaked in 50% carbendazim 600 times solution for disinfection for 20-25 minutes, and then taken out.

High-quality and High-yield cultivation techniques of Pleurotus ostreatus
Pleurotus ostreatus has thick body, crisp, tender and delicious stalk, rich in nutrition, and contains eight kinds of amino acids necessary for human body, among which the contents of lysine, arginine and glutamic acid are high, and it has certain medicinal value. The following key techniques should be mastered in its high-yield cultivation. The seedlings of fine strains were white, dense, sturdy, vigorous and uniform. Where found that there are yellow, green, black, orange and other colors are miscellaneous bacteria infection, such strains should be prohibited. The optimum temperature for the emergence of Pleurotus ostreatus in the best cultivation period is 16 ℃ ~ 3.
