Strawberries are cool, not resistant to high temperatures and droughts. If the summer is poorly managed, plants will experience serious physiological disorders and even cause massive deaths. Strawberry summer management measures are as follows:
1, irrigation moisture, shade cooling. Strawberry roots are shallow, drought resistance is weak, leaf area is large, and evaporation is strong. If the ground is not watered frequently to keep the soil moist, it can easily cause the stems and leaves to wither and die. Therefore, when there is white cracking in the local area, the land with irrigation conditions should be furrowed at night. After the water penetrates the seedlings, irrigation will be stopped to eliminate the water in the ditch. For the land without irrigation conditions, it is better to splash water and drought every morning and evening. Pouring enough water to keep the soil moist and reduce the surface temperature. In addition, it is best to put a shed of about 1 meter high on the surface of the rake, cover some fireweed and other objects on the top, and plant some high stalk crops on the buckwheat noodles, such as corn, sorghum, and legume-like vegetables, etc. But can not be planted too dense, so as to avoid poor ventilation, lack of light, affecting the normal growth of strawberries.
2, directional pressure vines, take root and promote seedlings. During the growth of summer and autumn after the strawberry is harvested, the stolons will successively produce 3-5 seedlings. The strawberry nursery used for the propagation of seedlings in order to enable each seedling to grow into a strong seedling, the stem should be straightened and aligned in a timely manner during the emergence of seedlings. The new strains sent out were slightly pressed with soil to promote new roots.
3, remove weeds. Weeds can easily compete with strawberries to compete for water, affect the robust growth of strawberries, and reduce the drought resistance of strawberry plants. They must be removed frequently. Do not loosen the strawberry roots during weeding so as to avoid seedling death. While weeding, we must remove the yellow leaves and dead leaves of strawberry, reduce nutrient consumption and water evaporation, and promote ventilation.
4, pest control. During the summer and autumn, the pest that threatens the strawberry the most is the cricket, often biting bad plants, causing the whole plant to die. 800-fold dipterex or 1000-fold dichlorvos can be used to water seedlings, and can also be captured manually. Adults of common crickets often spawn on unrefined manure heaps, and the use of adequately cooked organic fertilizers can mitigate harm. In recent years, with the popularization of cultivation techniques in protected areas, the occurrence of wild grasshoppers (commonly known as snouts) in greenhouses and arch sheds has become more and more severe, which has seriously affected the yield and quality of strawberries. Attention should be paid to the timely adoption of artificial traps for prevention and control.
