Spring is the period of strawberry vegetative growth and reproductive growth. Strengthening management during this period is extremely important for improving strawberry yield and improving quality.
Pay attention to timely uncovering the film and refining: When the average temperature of the day is stable at around 10 °C, the overwintering cover should be removed. After uncovering the cover, the dead leaves, diseased leaves and old leaves should be removed in time to improve the light transmission conditions and prevent the occurrence of diseases.
Pay attention to weeding and weeding loose soil: timely weeding and weeding in the spring, we must be shallow, so as not to hurt the root system and prevent the soil from pressing the seedlings; timely clean up the drainage ditch, waist ditch, ditch, etc., to eliminate waterlogging.
Pay attention to the timely topdressing and watering: it should be combined with watering to apply once the fertilizer, 10-15 kg per mu or 20-30 kg of compound fertilizer; before the flowering in mid-April, chase the pre-flower fertilizer, and use compound fertilizer 10 -15 kg; in addition, spraying 2-3 times of 0.3% potassium dihydrogen phosphate solution on the foliar surface during the flowering period is beneficial to increase yield and quality.
Pay attention to sparse flowers and buds: the flowers on the strawberry inflorescences have good results, and the fruits are large and mature. Therefore, after the strawberry is bud, the thin flower buds should be removed to reduce the nutrient consumption, so that the fruits are large, mature, early, and of good quality, and 20%-25% of the late weak flower buds are eliminated.
Prevention and control of pests and diseases: Shallow shovel in early spring, effectively eliminating eggs and larvae of weeds and soil. For leaf spot, gray mold, blight, powdery mildew and other diseases, timely prevention in early spring, can be sprayed with 50% carbendazim or 70% methyl thiophanate 500-800 times, the main disease is caused by Aphids are transmitted with poison, and can be sprayed with 40% omethoate 800 times as early as possible. It is forbidden to apply chemical pesticides during fruit ripening.
Anti-rotten fruit: Strawberry plants are short and the fruit is easy to hang to the ground, causing contamination and decay, which has a great impact on yield and quality. It can be placed around the plants with hay after flowering so that the fruit does not come into contact with the ground.
