Hazelnut cultivation techniques wild hazelnut recovery management

Third, wild hazelnut recovery management

1, the selection of the target

The hazelnut forest with thicker soil, fertile soil, well-drained sunny slopes, semi-sunny slopes, and concentrated lower parts, with a purity of more than 40%, was selected as the target for restoration. Any slope with a gradient below 15 degrees can be used.

2, recovery time

In general, it should be done in combination with firewood in autumn or winter or early spring.

3, method of recovery

1 division

According to the determined natural conditions such as the Yamagata Park Road, it is divided into a number of communities, each of which is 2-3 acres, and a 1-meter-wide operation road (Shunshan) is left between the communities.

2 impurity removal and stripping

In combination with the banded rakes, the non-purpose tree species and weeds in the hazel orchard are removed to make it a pure hazelnut forest. Leveling and thinning are carried out along the contour line (Yokoyama), with a bandwidth of 1 to 1.5 meters, and a bandwidth of 4 to 6 meters. This is a year-round rotation. There are harvests every year.

3 adjust the density of hazel forest

In combination with the strip-shaped flat boring operation, the internal dense strains, disease-damaged strains, mechanically damaged strains, and new germination strips of the retained filberts are cut out to achieve excellent quality, ventilation, light transmission, and promotion of sturdiness. Generally 2 years old hazel branches retain 20-25 plants per square meter, 8893-11116 strains per acre; 3 years old hazel forests retain 11-15 strains per square meter, 4891-6669 strains per acre.

4 replanting

The uneven distribution of wild hazelnuts is a common phenomenon. Seedlings can be taken on site for replanting. In other words, they are dug out from dense places and replanted into open space or overly sparsely populated areas to achieve uniform growth and distribution.

5 flat update method

It is advisable to use a guillotine knife or a branch cutter, or to use a small-sized machine to cut off the flat ground. The guillotine should be as low as possible, generally not exceeding 10 cm. Elevation of the mouth is not conducive to the growth of newborn buds.

6 except for the cut grass

In addition to sprouting, it is necessary to remove the germinating branches between bands and plexuses to ensure normal space, and at the same time to remove germinating twigs in the bands and plexuses in order to reduce the consumption of water and nutrients. 2-3 times a year. For the first time from late April to mid-May, the main stems of the last year were cleaned up and the newly emerged shoots were removed. Combine the grass later each time.

Mowing the grass is to control weeds and reduce the competition for moisture and nutrients with the hazel tree. Gradually remove the grass from the slope above 10 degrees, and keep the grass; if you want to remove the big grass above 10 degrees, leave 10-15 centimeters and keep the grass. 2-4 times a year. It can generally be conducted in the middle or late May, mid-June, or mid-July.

Veterinary medicine is informally as old as the human/animal bond but in recent years has expanded exponentially because of the availability of advanced diagnostic and therapeutic techniques for most species.

Veterinary drugs used properly, medications are a safe way to keep animals in good condition while preventing the spread of disease to other animals and neighbouring herds or flocks. They help to prevent costly losses to agricultural producers.
