cultivation techniques

1, timely colonization

It can be planted from February to June in spring and from September to 65438+February in autumn every year. Before planting, dig a pit according to the plant spacing 1 m and row spacing 1.5 m, with a depth of 30-50 cm and a diameter of 30 cm. After spreading a layer of base fertilizer in the hole, cover it with a layer of fine soil, each hole species 1 plant. After covering the soil, properly compact and pour water.

Topdressing nitrogen fertilizer again in August, using urea 15 kg per15 hectare, ditching and sowing beside plants, and covering with soil. When there are many weeds in summer, pay attention to weeding.

3, plastic pruning

When cutting in winter, 4-5 stout branches on the trunk are selected as the main branches, and the rest are used as flower cuttings.

The main diseases are powdery mildew and anthracnose, which can be controlled by 70% thiophanate-methyl and triamcinolone acetonide.

5. Harvest and processing

When it blooms, it should be harvested in time. The method is to pick the buds from outside to inside and from bottom to top before they open. After harvesting, it should be processed and dried in time.
