Reasonable planting density is a prerequisite for yield assurance. Reasonable planting density and species, varieties (strains), rootstocks, cultivation techniques, the use of tree shape, terrain, soil and climatic conditions and other factors. In fertile soil, flat terrain, planting distance should be larger; slope, thin soil mountain hazelnut garden, planting row spacing can be smaller. Growth of vigorous, open crown varieties, planting plant spacing should be larger; growth of weak, upright crown compact varieties, planting plant spacing can be smaller. According to the different purposes of cultivation, cultivation density should also be different. Some for the early yield, can be used to plan dense planting, early dense planting, later garden can be deforested when the depression. Later production does not need seedlings, can be converted to production garden. Such as the use of single stem form dense planting, row spacing of 2 meters × 3 meters, every 667 square meters can be planted 111 plants. After the tree is old, it can be felled or transplanted on the line to 4 meters × 3 meters.

Because of its tall crown, the bush is weak, and the dryness is slightly strong, cultivation of more than a single stem shape and less dry bush shape, so the cultivation density is smaller than the flat European hybrid hazelnut, row spacing is larger. According to different varieties in order to seek early high yield, planting spacing is getting smaller and smaller, the new hazelnut plant spacing 3 meters × 4 meters, 3 meters × 5.5 meters, 4 meters × 5 meters, 5 meters × 5 meters, than 20 years ago narrowed down 1/2.

Planting method to determine the hazelnut tree groups and leaf curtain layer in the hazelnut garden in the form of the configuration of the economic use of the land and field management has an important impact. Under the premise of determining the planting density, can be combined with the local natural conditions and the biological characteristics of hazelnut, to determine the cultivation method. Whether it is flat European hybrid hazelnut or European hazelnut, the commonly used cultivation methods include rectangular planting, square planting and triangular planting. When building the garden, the planting rows should be north-south rows on the flat land, which is conducive to the uniformity of light to the tree. The mountains are planted along the contour.

1. rectangular planting This is a widely used planting method in China. It is characterized by row spacing greater than the plant spacing, good ventilation and light, to facilitate mechanized operations and harvesting. The formula for calculating the number of plants planted is: the number of plants planted a planted area / (row spacing × spacing)

2. Square planting This planting is characterized by equal spacing between rows and spacing, good ventilation and light penetration, easy to manage. If densely planted, the canopy is easily closed, poor lighting, intercropping is inconvenient, so the application is less. The formula for calculating the number of plants planted is: the number of plants planted a planted area / (planting distance)2

3. triangular planting triangle planting is greater than the spacing between rows, two rows of hazelnut trees staggered each other into a triangular arrangement of the planting method. This way can increase the number of plants per unit area, more than square planting 11.6% of the plants. However, due to the small row spacing, not easy to manage and mechanical operations, the application is less. Cultivation of the number of plants is calculated as follows: the number of plants planted a planted area / [O.86 × (planting distance) 2]

4. Equal height planting This planting is suitable for sloping land and the construction of terraces and rousing trenches in the orchard, which in fact is a rectangular planting in the sloping orchard applications. Planting, should master the "big bend on the potential, small bend to take the straight" method, adjust the contour, and too wide, too narrow in the appropriate increase or decrease in planting line, planting in the line according to the spacing. The formula for calculating the number of cultivated plants is: the number of plants planted a planted area / (row spacing × spacing)

5. Band planting, also known as double row planting, hedge planting. Generally two rows for a band, the band spacing for the row spacing of 2 to 3 times. The band can be rectangular planting, row spacing should not be too small.
