Land selection and treatment
Strawberries in four seasons like light, fat and fear waterlogging, so we should choose the land with high terrain, loose soil and fertile soil to build gardens. Before planting, the land should be ploughed 30cm~40cm, and the land should be planted in a flat border, with the general ridge width 1.2m~ 1.5m and the ridge height 15cm~20cm. After ridging, a small amount of water can be poured to make the soil sink.
Seedling selection and planting
Seedling selection and planting are the key to the harvest of strawberries in four seasons. Generally, it is required to choose large seedlings with 4~6 large leaves, strong roots and stems and no pests and diseases. Seedlings are usually planted from mid-March to early April in spring, and from late August to mid-October in autumn.
Fertilizer and water management
Strawberries in four seasons bloom and bear fruit continuously in a year, and the demand for fertilizer is very high, and topdressing is needed 4~6 times a year. Nitrogen, phosphorus and potassium compound fertilizer is selected as the fertilizer, and the amount of fertilization per 100 square meter is about 10 kg. Pay attention to watering in time after fertilization. Pay attention to drainage in rainy season to prevent strawberry from rotting roots and stems.
extermination of disease and insect pest
The common gray mold of strawberry in four seasons should be prevented, planted reasonably close, with the spacing of 40cm~50cm, and cultivated in triangle, so as to avoid flooding and strengthen the ventilation in the park. Chemical control should also be done well, and 50% aqueous solution of botrytis cinerea 1000 times can be sprayed evenly every/kloc-0 ~15 days from the inflorescence exposure to the harvest period.
