Hazelnut Tree Planting Methods and Precautions, and Which Regions Are Suitable for Growing Them?
When it comes to hazelnuts, everyone should be familiar with them. They are one of the nuts we commonly eat in daily life, with a hard and crisp texture and a delicious taste, and they are rich in nutrients, deeply loved and sought after by food lovers. In fact, growing hazelnut trees is also a relatively profitable planting project, and at the same time they have strong vitality and are very easy to grow. So how should hazelnut trees be planted? Let's find out together with the editor below!
Hazelnut Tree Planting Methods and Precautions
1. Soil
Hazel trees have strong adaptability to soil and can grow, develop and bear fruit on light sandy soil, loam, light clay soil and light saline-alkali soil, but the most suitable soil is sandy loam. The soil layer should be more than 50 cm thick. They have strong adaptability to soil acidity and alkalinity, and can grow and bear fruit normally within a pH range of 5.5-8.0.
Planting depth: The root system cannot be buried too deep or too shallow. After planting, the root collar should be level with the ground or slightly lower than the ground by 5 cm. A burial depth of 6-10 cm above the root collar is appropriate. If the soil in the hole is loose, in order to prevent the soil in the hole.
2. Land preparation
Before planting, level the land and remove miscellaneous trees, weeds, stones and other objects. Plow and turn the soil to a depth of more than 20 cm. Planting hole specifications
hazelnut, diameter 70-100 cm, depth 60-70 cm. When digging planting holes, the surface matured soil and subsoil should be kept separate. When backfilling, mix the subsoil with organic fertilizer, stir evenly, and return it to the lower half of the planting hole, then return the surface matured soil to the upper part of the planting hole. Land preparation and hole digging are best completed in the autumn of the year before planting.
3. Timing
To improve the survival rate, autumn planting is recommended. Generally in October-December; in the Yellow River and Yangtze River basins, it is suitable in late February to early March, and at the latest no later than mid-March. Hazelnut tree planting must be completed before bud break. If the seedlings have already sprouted before planting, the survival rate decreases.
4. Planting
According to the variety planting plan, place the seedlings into the prepared planting holes so that the root system spreads out, and at the same time pay attention to firming the soil so that the root system and soil are closely combined. Then fill in moist soil. When filled to half, gently lift the seedling upward, while filling soil and pressing it firm, so that the root system and soil are closely combined. Then build an irrigation tree basin around the seedling, with a diameter of 1 cm, to facilitate irrigation and water storage. After planting, irrigate immediately, and irrigate fully and thoroughly. After the water seeps down, cover the tree basin with plastic film to retain moisture and increase temperature, promote root activity of the seedlings, and improve the survival rate.
5. Precautions
It should be determined according to tree age, shrub size, soil fertility and the type of fertilizer. Poor sandy soil should be given more organic fertilizer, while soil with deep soil layers and high humus content can be given an appropriate amount less.
Generally, for basal fertilizer application, 2-3 year old trees are given 7-10 kg of manure per plant, 4-5 year old trees are given 30-40 kg per plant, 6-7 year old trees are given 50-60 kg of organic fertilizer per plant, and later, as tree age and yield increase, the amount can be appropriately increased.
Where Hazelnut Trees Grow
Hazelnut trees grow in mountain shady-slope shrublands at an altitude of 200-1000 m. They have strong cold resistance and like a humid climate.
Hazelnut trees are distributed in China (Heilongjiang, Jilin, Liaoning, Hebei, Shanxi, Shaanxi, etc., and are cultivated in Jiangsu), Turkey, Italy, Spain, the United States, Korea, Japan, eastern Siberia and the Russian Far East, and eastern Mongolia.
How Many Years Until Hazelnut Trees Bear Fruit
Hazelnut trees generally begin to bear fruit after 3-4 years from sexually propagated seedlings, and asexually propagated hazelnut seedlings begin to bear fruit after 2-3 years, entering full fruiting stage after more than 7 years, and the lifespan of the shrub can reach more than 50 years.
Growing Conditions for Hazelnuts
1. Temperature: Different types of hazelnut trees have different temperature requirements. European hazel prefers a warm and humid climate. It is suitable for areas with an average temperature of 13-15°C, an absolute minimum of -10°C, and an extreme high temperature of 38°C. Ping'ou hybrids are more cold-resistant than European hazel and are suitable for cultivation in areas with an average annual temperature of 7.5-13°C and a minimum temperature that can reach -30°C.
2. Light: Hazelnut trees are light-loving plants and generally require annual sunshine hours of more than 2100 hours; otherwise, flower bud formation is reduced and yield is low.
3. Soil: Hazelnut trees like to grow on fertile, well-aerated sandy loam. Ping'ou hybrids in particular have high soil requirements. Dry sandy soil, heavy clay soil, swamps, saline land and low-lying land are all unsuitable for establishing hazelnut orchards. Ping'ou hybrids require a soil pH of 6.5-7.5, while European hazel requires 5.5-7.
If you are still considering planting as a startup, you might consider growing hazelnut trees. Hazelnut trees have strong adaptability and can be planted by riversides, in mountainous areas and on hilly land. Under artificial cultivation, they generally bear fruit in 2-4 years, which means that in about 3 years you can generally see obvious returns!
