Detailed Explanation of Key Strawberry Cultivation and Management Techniques

Because strawberries are rich in carotene and aspartic acid, they have a certain nourishing and regulating effect on the body, and have become a fruit and vegetable product that people love. Now the editor of Tuliu.com will talk about the key management techniques for strawberries.

1. Earthing up: In late September, carry out a thick earthing up together with loosening the soil and weeding, so as to promote more roots on the seedlings and prevent the roots of old seedlings from being exposed.

2. Flower thinning: The flowers on the 3rd and 4th level branch stems of the strawberry inflorescence are often sterile. Before flowering, when the flower buds begin to separate from each other, these buds should be thinned out, no later than the opening period of the first flower.

3. Disease and pest control: The main diseases are gray mold and powdery mildew, and the main pests are aphids and red spiders. High-efficiency, low-toxicity pesticides should be used for control, but they are strictly prohibited during the fruit harvest period.

4. Mulching for overwintering: By late October, as the temperature gradually drops, a greenhouse should be built as soon as possible to prevent freezing damage. From late March to early April of the following year, as the temperature rises, begin to uncover the film on both sides of the greenhouse. Afterwards, as the temperature rises, gradually remove the film to lower the temperature inside the greenhouse and improve ventilation.

5. Topdressing: When strawberries enter the flower bud development stage and the flowering and fruit-setting stage, plant growth is large and fertilizer demand also increases. Therefore, generally no topdressing is done before fruit harvest. After fruit harvesting begins, each time a batch of fruit is picked, apply topdressing once together with irrigation. If topdressing is not done in time, premature aging is likely, affecting yield. Generally, apply 5~10kg of 15% ternary compound fertilizer per 667 sq m, once every 15~20d, for 3~4 consecutive applications.

6. Careful picking: Harvesting begins in early December, once every 1~2d, and the harvest period can generally continue until the end of May. The suitable time for picking is in the morning. When picking, the action should be gentle, pinch the fruit stalk with the hand, and pick it with the stalk attached. Do not damage the strawberry, otherwise it is prone to rot and the strawberry quality will be affected.
