Postharvest management technology of strawberry

Ploughing and loosening the soil.

After harvest, the soil was trampled many times, resulting in hardening and grass shortage, which seriously affected the growth of strawberries. Therefore, it is necessary to plough and weed in time. The depth of intertillage is 3cm to 4cm, which should not be too deep to prevent damage to the root system. Intertillage can remove weeds and disease and withered leaves in loose soil, improve ventilation and light transmission conditions, promote robust plant growth, and efficient strawberry planting techniques to prevent diseases. Before the occurrence of a large number of new roots in autumn, it is appropriate to cultivate the fine soil around the roots to expose the seedling heart, so as to promote the occurrence of new roots and improve the ability of cold resistance and drought resistance.

adequate manuring.

Apply fertilizer in time after harvest to supplement the nutrition loss caused by the result and reinvigorate the root system. Strawberry has higher requirements for fertilizer. Reasonable fertilization can make the plant develop healthily, the flower bud is full, the fruit is large, the sugar content is high, and the flavor is colorful. In the case of sufficient base fertilizer, topdressing should control the amount of nitrogen fertilizer according to the plant growth, so as not to affect the overwintering. After strawberry harvest, it can be combined with watering and topdressing compound fertilizer, 22.5 kg per mu, which can promote plant nutrition accumulation and flower bud differentiation. Overwintering fertilizer can be ditched and applied once mature human feces and urine before freezing to improve the overwintering ability of plants. After strawberry harvest, watering times and irrigation should be reduced to prevent the consumption of a large amount of nutrients due to the vigorous growth of stolons.
