What are the contents of cucumber seedling temperature management?
The ground temperature is maintained above 20°C, and the temperature is maintained at 30-35°C and above 20°C at night. When 1/3 of the ground is broken, the mulch film should be uncovered so as to avoid roasted seedlings. Seedlings who wear "caps" should be removed promptly. Seedlings should be appropriately reduced in temperature within 5 days, during the day, 25 to 27°C, 12 to 15°C at night, and 20°C for the ground temperature. The first true leaf growth period must increase the temperature difference between day and night, during the day 28 ~ 32 °C, 12 ~ 15 °C at night is appropriate; during the first true leaves to two leaves and one heart, it is necessary to gradually increase the amount of air release, the temperature during the day should also reduce some 25 to 28 °C is appropriate, the maximum does not exceed 30 °C, the night temperature is still maintained 12 ~ 15 °C is appropriate to reach 6 to 7 days long a true leaf. 7 to 10 days before planting, the greenhouse grasses cover the late cover and gradually increase the ventilation and ventilation time. During the day, the temperature gradually drops to 20-23°C, gradually decreases to about 10°C at night, and requires a short period of exercise of about 5°C. To adapt it to the environment after planting Polypropylene is a thermoplastic polymer used in a wide range of applications among which we usually use it to make pharmaceutical packaging products. Each time when we receive the original Polypropylene materials we have ordered, we will do a series of modifications on them to form some useful pellets that will used in our products. One kind of these reproduced particles will be used to make caps for pharmaceutical ampoule bottles. We now have a big stable customer base in our domestic market. In future, we will do our best to serve the worldwide clients. If you are looking for a cooperator in our country, maybe we are a good choice for you. Warmly wait for your inquires!
