Celery planting: what should we pay attention to sowing celery in summer?

What should we pay attention to sowing celery in summer? Please give guidance that the summer temperature is high, which is not conducive to celery sprouting, and low temperature sprouting must be carried out. Soak the seeds in water for half an hour, remove them, rinse them, wrap them with wet gauze, hang them in a well 20cm above the surface of the water or put them in a refrigerator about 4 ℃. Rinse the seeds 1-2 times a day to keep the seeds moist. After 4-5 days, when the seeds begin to germinate, they can be sowed into the seedbed to raise seedlings. It takes 35-45 days from sowing to transplanting celery in summer. During this period of time, the temperature is high and there are many torrential rains. A flat-roof sunshade should be built, which is 1.5 meters away from the bed, covered with straw, or a small arch shed can be built to cover the sunshade net. When the celery seedlings grow to 10-13 cm high, the plant spacing is 10 cm and the row spacing is 15 cm. After planting, a shed was built to cover the sunshade net to reduce the temperature, make celery grow healthily and prevent bolting. Celery has a long growing period and large growth, so it is necessary to replenish fertilizer and water in time. In addition to applying sufficient farm fertilizer, base fertilizer is applied with 50kg compound fertilizer with high potassium content per mu. In the future, according to the growth situation, dung water can be applied and a small amount of urea can be added to the dung water to improve the quality of celery. Celery is prone to diseases and insect pests, especially aphids and gray leaf spot disease, because of its high population density and high field humidity in the later stage of celery growth. Aphids can be sprayed with 3000-fold solution, and gray leaf spot can be sprayed with 3000-fold methyl topiramate powder.
