After harvesting strawberries, it is the key period for nutrients to need nutrients. Strengthening the management of strawberry harvesting can achieve the goal of large fruit, high quality and high yield.
Remove the stolons. After the strawberry fruit is harvested, a large number of stolons are produced. The production of the stolons consumes a large amount of nutrients per plant, affects flower bud differentiation, and reduces the yield and quality of the strawberry in the leap year. Therefore, after picking fruit from strawberries, the stolons and dead leaves must be removed in time to prevent the plants from being too dense and poorly illuminated.
Cultivate loose soil. After the harvest, the soil was repeatedly pedaled and grassy, ​​which seriously affected the growth and development of strawberries. Therefore, it is necessary to carry out cultivating and weeding in time. The depth of cultivating is 3-4 cm, not too deep, to prevent damage to the root system, cultivating to loosen the soil to remove weeds, combined with eliminating dead leaves, improving ventilation and light transmission conditions, promoting plant growth and preventing disease. The soil is cultivated after the berry is harvested and before the new roots occur in autumn. The fine soil where the roots are exposed to the roots is suitable. Promote the occurrence of new roots and improve the ability to resist cold and drought.
Rational fertilization. After harvesting, timely fertilization can supplement the nutritional losses caused by the results, rejuvenate the production potential, strawberry requirements for fertilizers are higher than other fruit trees, reasonable fertilization can make plants grow and develop vigorously, flower buds are full, fruit is large, sugar content is high, The taste is bright. In the case of sufficient base fertilizer, the topdressing should control the application rate of nitrogen fertilizer according to the growth of the plant, so as to avoid the influence of greedy and long-lasting wintering. After harvesting, the strawberry should be compounded with 22.5 kg per mu, which can promote the nutrient accumulation and flower bud differentiation of the plant. The top dressing can be combined with watering. The wintering fertilizer can be used to open the ditch before the freezing to apply the decomposed human excrement to improve the wintering ability of the plant. Generally, after the strawberry is harvested, the number of watering and the amount of watering should be reduced to prevent the stems from growing vigorously and consuming a large amount of nutrients.
Control pests and diseases. For red spider, it can be controlled with 20% dicofol and 600-1000 times liquid mixture. For leaf spot, 70% chlorothalonil WP 500-700 times solution or 70% mancozeb WP can be used for prevention and treatment. For gray mold, 25% carbendazim WP 300 times solution, or 50% captan WP 800 times solution, or 50% thiram 600 times solution, or 75% chlorothalonil 600 solution, or 70 % methyl thiophanate 1500 times liquid spray control.
