The temperature range of celery seed germination is 5~25℃, germination is hindered above 30℃. When celery is planted in summer and autumn, the temperature is relatively high, and low temperature treatment on the seeds can make it emerge early and evenly.
For low-temperature treatment, first wrap the seeds with gauze, and soak them in well water. The water temperature is lower than 25°C. The seeds are soaked for 10 hours, and then the germination is accelerated at low temperature. There are 3 kinds of germination methods, which can be selected according to the actual situation. One is to wrap the seeds with gauze and put them in a cold storage at -5°C to -3°C for 24 hours, then put the frozen seeds indoors and let them melt, and they will germinate in 2 to 3 days. The second is to place the seeds wrapped in wet gauze in the fresh-keeping room of the refrigerator and keep them at 15-20°C for 3 to 5 days to germinate. The third is to wrap the seeds with wet gauze and hang them in the well, 30 cm away from the water surface in the well, and they will germinate in 3 to 5 days. In the process of accelerating germination, water should be added in time, the seeds should be washed at least once a day, and the seeds should be properly exposed to light in the middle. After accelerating germination, it is suitable for seeding, and after sowing, cover with straw curtain to keep moisture. If possible, set up a 1-meter high awning to facilitate the emergence of seedlings.

Sun-Shading Net is a series of colored shade nets with special optical properties which improve the utilization of solar radiation by agricultural crops. This technology promotes differential stimulation of desirable physiological responses, which determine the commercial value of each crop. This is an economical and environmentally friendly alternative to current labor-consuming methods (such as pruning and thinning) and intensive use of growth regulators and other chemicals. ChromatiNet enables growers to control vegetative growth characteristics, such as leaf size, branch length and plant height in plants, as well as the rate of maturation and flowering. This enables adaptation to market preferences, with clear economic advantages.
Greenhouse Sun-Shading System can reduce solar load, and cool down the inside temperature and create a comfortable environment for the plants.
