First, pay attention to control germination temperature. In summer, due to high outside temperature and difficulty in germination, it can be adapted to local conditions. The germination ambient temperature is controlled at 15 to 20 degrees Celsius and germination occurs after about 10 days. Second, prevent continuous cropping or soil consolidation. Continuous cropping or soil compaction is often caused by two reasons: on the one hand, poor bed soil quality; on the other hand, insufficient bottom water and low humus content. Therefore, it is necessary to select soil-rich, fertile, soil organic matter-rich plots to build seedbeds. Third, scientific fertilizer. Excessive application of nitrogen fertilizer, resulting in leggy seedlings, thin pale leaves, less root system. When the temperature is too high, the respiration of the seedlings is enhanced, more nutrients are consumed, weak seedlings are easily formed, and dead seedlings are caused. Fourth, shade and rain. Summer heat, light, heavy rain environment is not conducive to the emergence of celery, so it is necessary to shade rain seedlings. Fifth, pay attention to the prevention and control of underground pests. In order to prevent earthworms and other underground pests, bran can be fried in a pan, and 90% trichlorfon powder is added to mix and make baits and sprinkled around the seedbed. These are some of the masks, and masking practices, that I and other WIRED staff members are using to keep ourselves and our families safe. I've also highlighted sustainable options, ones from diverse and small manufacturers, as well as companies donating to worthy causes. Try a few, but remember to keep washing your hand regularly, staying at home when possible, and maintaining at least a 6-foot distance from others in public (preferably outdoors). medical 3-ply face masks, anti-dust face mask,3 ply earloop for kids face masks Suzhou Xuanweicheng Biotechnology Co., Ltd , https://www.xwc-medical.com
