To keep strawberries safe through the summer, the following methods can be used:
Irrigate to retain moisture, shade to lower the temperature. Strawberry roots are relatively shallow and have weak drought resistance, and the leaf area is relatively large, so evaporation is vigorous. If the plants are not watered frequently to keep the soil moist, the stems and leaves can easily wilt and die. Therefore, when the ground surface turns white and cracks, furrow irrigation should be carried out at night. For plots with no irrigation conditions, water should be sprinkled every morning and evening to keep the soil moist and lower the surface temperature. It is best to build a shade shed about 1 m high over the ridge surface and cover the top with some straw. Tall-stem crops such as corn can also be planted along the edges of the ridge, but they must not be too dense, so as to avoid poor ventilation and insufficient light, which would affect the normal growth of strawberries.
Directional runner pressing. During the summer and autumn growth period after fruit harvest, runners will produce 3-5 times of daughter plants. If new plants are not being propagated, they should be removed in time to avoid consuming the nutrients of the mother plant and reducing the strawberry yield the following year. In strawberry nurseries used for propagating seedlings, in order for each batch of daughter plants to grow into strong seedlings, during the plantlet-producing period the runners should be promptly straightened in a fixed direction and lightly pressed with soil to promote new root growth.
Intertillage and earthing up. The new root zone of strawberries has the growth characteristic of moving upward year by year. Therefore, after new plants have grown for 1 year, attention should be paid to earthing up around the base, mainly carried out in time from after fruit harvest to before the large-scale emergence of new roots. The thickness of the earthing should be such that the crown of the seedling is exposed. Intertillage can be carried out together with topdressing and earthing up, and weeds should be removed.
Pest and disease control. At this time the main pest is white grubs, which can be controlled by watering the roots with 800-fold trichlorfon solution or 1000-fold dichlorvos solution. The adult of the white grub, the scarab beetle, often lays eggs on piles of undecomposed fertilizer. Using fully decomposed organic fertilizer can reduce the damage.
