6.温度管理 定植后最主要的问题是如何提高地温,最有效的办法是提高棚内气温。一般晴天棚内温度达到35℃～38℃,基本上不揭膜放风,几天后再放风。定植后温度管理的另一个重点是防寒防冻。晴天棚内白天温度一般可达到要求,但夜间因塑料薄膜的保温性差,棚内温度比露地一般只能高2℃。2月 6. Temperature Management The most important issue after colonization is how to improve the ground temperature, the most effective way is to increase the temperature inside the shed. Generally sunny shed temperature reached 35 ℃ ~ 38 ℃, basically do not expose the film leak, a few days before the wind. Another focus of temperature management after planting is antifreeze. Sunny daytime temperature during the day can generally meet the requirements, but due to the poor insulation of plastic film at night, the shed temperature than the general open only 2 ℃. February
