Planting conditions of hazelnut tree

Hazelnut tree is a shrub or small tree belonging to the genus Hazelnut of Betulaceae. It is one of the four dried fruits. It has a high planting prospect. It is usually wild in the shady slope shrubs of mountains at an altitude of 200~1000 meters. It has strong cold resistance and likes humid climate. It is more like light. Sufficient light can promote its growth and development. Let's take a look at the planting conditions of hazelnut tree.

temperature conditions

Different types of hazelnut trees have different temperature requirements. Hazel loves warm, humid climates. Suitable for average temperature 13~15℃, absolute minimum-10℃, extreme high temperature 38℃ area. Compared with Corylus heterophylla L., the hybrid is cold-resistant and suitable for cultivation in the area with annual average temperature of 7.5~13℃ and minimum temperature of-30℃.

lighting conditions

Hazelnut trees are light-loving plants, generally requiring annual sunshine hours of more than 2100 hours, otherwise flower bud formation is less, low yield.

soil conditions

Hazelnut trees like to grow in fertile, well-ventilated sandy loam soil, especially flat European hybrid soil requirements are high, dry sand, clay heavy soil, swamp, saline land and low-lying land are not suitable for the establishment of hazelnut garden. The soil pH value of the hybrid is 6.5~7.5, and that of Corylus heterophylla is 5.5~7.

cultivation technology

Hazelnut tree branches easy to root, adventitious buds easy to sprout roots. Therefore, seedlings are usually cultivated by layering or grafting. For layering in early spring, use annual healthy budding shoots, and for layering in June, use current year's shoots as material. Grafting seedlings, mostly using Corylus heterophylla seedlings as rootstock
