1. Site selection

For planting octagonal trees, the northern slopes of hills and mountains with undulating terrain and shelter from the wind should be selected, and the soil should be deep, fertile and loose, and the plots should be more convenient for drainage and irrigation. .

2. Timely planting

The best time for planting octagonal trees is before and after the Great Cold. Generally, the row spacing for planting is 4 meters × 5 meters or 3 meters × 4 meters, and the planting density is 750 plants/hectare. Dig a hole 30 cm deep and 40 cm wide and apply compound fertilizer. In order to improve the survival rate of afforestation, it is best to carry out afforestation on cloudy and rainy days.

3. Scientific fertilization

The best time to fertilize anise is February and June every year. Spring fertilizer can promote the growth of shoots, and summer fertilizer can promote the vigorous growth of anise. Fertilization is mainly nitrogen fertilizer, and compound fertilizer can be applied to young forests that are three years or older. For one to two-year-old trees, urea is applied every year.

4. Weeding

Weeds easily consume nutrients and water in the soil, so the octagonal garden should be cultivated and weeded at least 1-2 times a year. Weeding can be carried out manually. For large forest areas, glyphosate can be used directly for chemical weeding.

5. Prevention and control of pests and diseases

Effective control of anise anthracnose can reduce the source of the disease. If the disease is found, the infected branches and leaves can be completely removed and burned intensively. Spray 0.5% Bordeaux in the early stage of the disease. For prevention and control, in order to improve the disease resistance of the anise tree itself, more phosphorus and potassium fertilizers or farmyard manure should be applied.
