Strawberries covered with mulch are cold and cold-tolerant plants. When the ground temperature is 2 °C, the roots begin to move; when the temperature is 5 °C, the shoots begin to grow. According to meteorological data, the soil layer was 5-10 cm in February, the average ground temperature was around 2 °C, and the average temperature in March was around 8 °C. At this time, although the strawberry has begun to grow, but the ground temperature and temperature are low, the strawberry grows slowly. If the strawberry is cultivated in the open field in February, the ground temperature and temperature can be greatly improved, and the growth and development of the strawberry plant can be promoted. The suitable ground temperature for strawberry root growth is 15-20 °C, and the suitable temperature for the aboveground part is 20-25 °C. Therefore, in the early spring, on the basis of the strawberry covered mulch film cultivated in the open field, if there are conditions, the small arch shed can be covered. Under suitable temperature conditions, the strawberry began to grow from the roots 7 days after the roots began to move. The buds began to bloom after one month of growth, the buds reached flowering for 15 days, the flowers matured for 30 days, and the flowering period was 20 days. After the strawberry is budded, a hole is made in the mulch, and the plant is thrown out of the hole to allow it to grow naturally. Frequent cold currents in early spring, high temperature and low temperature, this period of time should pay special attention to strengthen management, pay attention to weather changes, if there is a cold current, a layer of mulch on the open floor should be covered with a layer, after the cold current to remove the upper mulch. The thermometer should be hung in the small arch shed. If the temperature in the shed exceeds 25 °C, the hole should be opened at the two ends or in the middle of the arch shed, and the air should be ventilated and cooled.
Clean up the plots of the pastures that cover the mulch before winter or cover the mulch in the early spring. When the temperature rises in the spring, the dry leaves and weeds in the garden should be removed to facilitate ventilation and increase the ground temperature.
Loose soil, weeding and spring should be loosened in time, but should not be too deep, so as to prevent the soil from pressing the seedlings. The temperature under the mulch is high, and it is easy to grow weeds. The top of the thick wire can be bent into thin slices; the base of the strawberry is inserted into the film and the grass is lifted out of the ground.
When watering begins to sprout and spread leaves, water is poured in time, and the amount of water is not too large. From the flowering period to the fruit expansion period, the water demand is gradually increased. It should be noted that the watering is repeated 2 to 3 times to keep the soil moist.
Fertilization generally 667 square meters of urea 5 - 7.5 kg, compound fertilizer 1O - 15 kg. During the flowering period to the fruit expansion period, the leaves were sprayed with 0.2% potassium dihydrogen phosphate solution 3-4 times.
The flowering and thinning strawberry plants generally have 2 to 3 inflorescences, and each inflorescence has 3 to 30 flowers. The flower buds formed in the late stage often become ineffective flowers, and the flower buds are excessive and consume a lot of nutrients. Therefore, when the first flower is opened, the high-grade flower buds are removed to concentrate the nutrients.
The fruit bedding is applied to the strawberry garden without mulching, and the grass or plastic should be laid under the ear within 2-3 weeks after flowering.
