The latest planting conditions of hazelnut trees

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

Temperature condition

Different kinds of hazelnut trees have different temperature requirements. Hazel prefers a warm and humid climate. The suitable average temperature is 13-15 ℃, the absolute lowest is-10 ℃, and the extremely high temperature is 38 ℃. Pingou hybrid is more cold-resistant than hazel, and is suitable for cultivation in the area with an average annual temperature of 7.5-13 ℃ and a minimum temperature of-30 ℃.

Light condition

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

Soil condition

Hazelnut trees like to grow on fertile, well-ventilated sandy loam, especially Pingou hybrids have high requirements for soil, dry sand, clayey soil, swamps, saline land and low-lying land are not suitable to establish hazelnut orchards. The soil pH value of Pingou hybrids is 6.5-7.5 and that of hazel is 5.5-7.

Cultivation technology

The branches of hazelnut trees are easy to root, and adventitious buds are easy to sprout roots and tillers. Therefore, seedlings are usually propagated by striping or grafting. The early spring striping uses annual robust germinating branches, and June crimping uses the same year's twigs as materials. Grafted seedlings are often used as rootstocks.
