How about planting hazelnuts in 2020? What are the planting techniques?

Hazelnut is a common nut, is a nutrient-rich precious dried fruit, welcomed by the market, so how about planting hazelnut in 2020? What are the planting techniques? Let's take a look.

How about planting hazelnuts in 2020?

Hazelnut nutritional value is very high, containing oil, protein, carbohydrates, vitamins, minerals, sugar fiber and antioxidant carbolic acid and other special components as well as eight amino acids and trace elements needed by human beings, while cultivated hazelnut taste, shape and color are excellent and other economic characteristics far more than wild hazelnut has extraordinary market competitiveness, in addition to it or set health care, nutrition and other food resources.

The market price of hazelnut in 2019 is about 25-30 yuan per catty, which will vary according to the origin and variety, such as Heilongjiang oval hazelnut in 25~35 yuan per catty, Liaoning hazelnut in 30~35 yuan/catty. Sales prices are relatively expensive. At present, hazelnut fruit market is almost very small, is in the early stage of development, there are more extensive planting prospects.

II. Hazelnut planting technology

1. Planting density

If you want to make hazelnut tree to achieve the desire of high yield, then hazelnut tree planting density should have a rationality, reasonable selection of hazelnut tree planting density is closely related to many factors such as species, varieties, rootstocks, cultivation techniques, tree shape, terrain, soil and climate conditions, so in the selection of hazelnut tree planting density to consider a variety of factors, so that hazelnut tree robust growth.

2. Planting density

The planting distance of hazelnut trees should be larger in fertile soil and flat terrain, and the planting spacing of hazelnut trees in mountainous hazelnut gardens with large slope and poor soil should be smaller. The planting spacing of hazelnut trees with vigorous growth and open crown should be larger, and the planting spacing of hazelnut trees with weak growth and upright and compact crown should be smaller. The different planting densities should also be different according to the cultivation purposes. Some of them can be planted in a planned manner for early high yield. After early dense planting, thinning can be used when the garden is closed.

3. Cultivation depth

Planting depth roots should not be buried too deep or too shallow, after planting root neck and ground surface or slightly lower than the ground surface 5cm, to root buried soil depth 6- 10cm is appropriate, if the soil loose in the hole to prevent watering after planting soil sinking too much and difficult to control the planting depth, should be properly watered before planting or slightly firm with feet in the hole soil.

4. Reasonable watering

The diameter of the tree tray is up to 1m, which is convenient for irrigation and water storage. After planting, irrigation should be carried out immediately and sufficient irrigation should be required. After water infiltration, the soil should be sealed to preserve moisture and the tree tray should be covered with plastic film to keep moisture and increase temperature to promote the root system activity of hazelnut tree and improve the survival rate.

5, timely pruning

A trunk is reserved, and then a reasonable skeleton is formed by shaping and pruning according to the growth and development characteristics of the hazelnut tree. Generally, there are three kinds of tree shapes adopted: less trunk cluster shape, single trunk shape and more trunk cluster shape. In the form of less trunk cluster shape, 3-4 basal branches are reserved as main branches and obliquely extend to different directions. The main branches of hazelnut tree have lateral branches, and the vegetative branches and fruit mother branches form a whole still open tree shape. In the form of single trunk, one trunk should be reserved. 3-4 evenly distributed main branches are selected on the trunk, lateral branches are selected on the main branches, and auxiliary branches and fruiting mother branches are attached on the lateral branches to form short trunks.

6. Fertilization and drying

Apply decomposed farm manure at the beginning of May, apply compound fertilizer in the middle of July, project additional fertilizer around the hazelnut crown in the second year of planting, but do not chase too deep. After planting, the hazelnut tree is divided into single stem shape and cluster shape. The plot with good soil, fertilizer and water conditions should be single stem tree shape with fixed stem height of 60-70 cm. Otherwise, it should be cluster tree shape with fixed stem height of 30-40 cm. The seedlings planted in the same year should strengthen water and fertilizer management to make them grow healthily and sprout a certain number of branches. Good degree of lignification to prevent excessive growth of hazelnut trees, autumn leaves after the cultivation of soil cold, soil up to 1/2 of the plant can be removed in the next spring cold soil, generally from the second year do not need to cultivate soil cold.
