Price and planting method of large hazelnut seedlings

Hazelnut is a woody grain and woody oil tree species, also known as Corylus, Corylus, mountain chestnut, etc., for the birch family Corylus deciduous shrubs or small trees, its comprehensive utilization value is very high, a wide range of uses. In northern China, the slopes, terraces and flatlands below 750 meters above sea level are most suitable for the growth of hazelnuts. Let's take a look at the price and planting method of big hazelnut seedlings.

How much is a big hazelnut seedling?

The price of large hazelnut seedlings is about 580 yuan, but the price varies greatly due to the specification, quality, origin and quantity of the seedlings. Hazelnut is distributed in the temperate zones of Asia, Europe and North America, and has a long history of cultivation in China. At present, there are 22 regions of Corylus in China, which are very rich in resources. in particular, there are large areas of hazelnut forests in Northeast China, Shanxi, Inner Mongolia, Shandong and Henan.

Planting conditions of big hazelnut

1. Temperature: big hazelnut has strong cold resistance, which is suitable for annual average temperature of 7.5-13 ℃. It can be cultivated in areas where the lowest temperature reaches minus 30 ℃.

2. Lighting: big hazelnut is a light-loving plant, which generally requires annual sunshine hours of more than 2100 hours, otherwise the flower bud formation is less and the yield is low.

3. Soil: big hazelnut has high requirements for soil, dry sand, clay, swamp, saline land and low-lying land are not suitable to establish hazel garden.

The propagation method of big hazelnut

1. Sowing and propagation: in the hazel forest, the plants with high yield, large fruit and no diseases and insect pests are selected as the mother tree, and the hazelnuts with large grains, full kernels and no diseases and insect pests are selected for sowing, and the seed germination power is maintained for one year, and the sowing time is suitable for spring, usually in the middle and last ten days of April.

2. Ramet propagation: there are two methods of ramet propagation: one is to dig up all the mother plants and divide them into several clumps or individual plants, each of which has roots and 2 branches, and the other is to dig up roots and tillers around the mother plant cluster and separate several plants, and the mother plant is still retained.

3. Root tiller propagation: there are two methods of root tiller propagation: one is to excavate the root tillers around the existing clumps to obtain seedlings, and the other is to propagate in a special mother garden. The mother plants to be propagated should be flat stubble in spring to promote the occurrence of root tillers.

4. Striping propagation: striping can be divided into horizontal crimping and bow crimping, either in autumn or spring, but it is the most suitable in spring. Bowed striping is divided into hardbranch crimping and twig crimping, which is carried out in early spring and twig crimping in the first and middle of June.

Planting method of big hazelnut

1. Site preparation and hole digging: the land is leveled before hazelnut trees are planted, weeds, stones and so on are removed. When digging holes, the topsoil should be separated from the subsoil, the subsoil should be mixed with organic fertilizer and then backfilled, and the topsoil should return to the upper part of the planting hole, it is best completed in the autumn of the previous year.

2. Planting time: in order to improve the survival rate, hazelnut trees should be planted in autumn, generally from October to December, the Yellow River and Yangtze River basins should be from late February to early March, no later than the middle of March, but they must end before budding, otherwise the survival rate will decrease.

3. Planting density: the planting density of hazelnut trees is determined by species, varieties, rootstocks, cultivation techniques, tree shape, topography, soil, climatic conditions and so on. Many factors should be considered in order to make hazelnut trees grow healthily.

4. cultivation depth: the root system of hazelnut tree should not bury the soil too deep or too shallow. it is required that the root neck and the surface of the ground should be slightly lower than 5 cm, and the depth of buried soil above the root system should be 6-10 cm.

5. Reasonable watering: irrigation tree plates are built around the hazelnut tree to facilitate irrigation and water storage. Immediately after planting, water should be irrigated. After water infiltration, the soil should be sealed to preserve soil moisture, and the tree plate should be covered with plastic film to maintain moisture and increase temperature, promote the activity of hazelnut root system and improve the survival rate.

6. Weeding and loosening soil: under the condition of loose soil and good ventilation, hazelnut tree has developed root system, strong tillering ability and exuberant growth, which is beneficial to growth and fruiting. Weeding and loosening soil should be carried out 2 or 3 times a year from the end of April to June.

7. Rational fertilization: pay attention to fertilization after the hazelnut tree is planted, usually apply rotten farm manure at the beginning of May, topdressing the compound fertilizer in the middle of July, and in the second year of planting, you can project the fertilizer around the hazelnut crown, but not too deep.

8. Timely pruning: hazelnut trees generally leave a trunk, and then trim them according to their own growth and development characteristics to form a reasonable skeleton. There are usually three kinds of tree shapes, namely, less trunk cluster shape, single trunk shape and multi-stem cluster shape.
