June is a critical time for nurturing and propagating strawberry runners. Proper management during this period is essential for ensuring healthy growth and high yields. Here are some key tips for June management of strawberries:
-
Disinfection: It's important to disinfect the greenhouse, soil, and substrate to kill harmful bacteria and nematodes. This helps alleviate consecutive cropping obstacles and reduces the likelihood of disease and pest infestations. Methods such as chlorinated lime disinfection, lime nitrogen disinfection, and Weibaimu disinfection can be used in areas with high risks.
-
Temperature and Humidity Management: As runners grow abundantly in June, strawberry mother plants enter a vigorous growth stage. To maintain optimal conditions, open the vents on the greenhouse's top and sides to ensure air circulation and reduce the temperature. Consider adding shading nets outside the greenhouse to further reduce temperature. It's ideal to keep the greenhouse temperature between 24 to 28 degrees Celsius to promote seedling growth.
-
Water and Fertilizer Management: During this period of vigorous growth, strawberries have high water and nutrient requirements. Water and fertilize them according to the principle of applying small amounts frequently to avoid over-fertilization. Water in the morning or evening on sunny days, avoiding midday watering to prevent root damage. Fertilize every 7 to 10 days with a balanced water-soluble fertilizer, avoiding nitrogen fertilization alone.
-
Disease and Pest Control: June's higher temperatures make it a peak period for aphids and mites. For aphids, use a 5% avermectin emulsion at 1500 times dilution combined with a 26% chlorfluazuron water dispersible granule at 750 times dilution. Regularly remove old and yellow leaves to reduce pest habitats. For diseases like anthracnose and root rot, use appropriate fungicides at recommended dilutions for effective control.
