蔬菜秧苗只有在适宜的环境条件下,才能生长健壮。这些环境条件主要有温度,光照,水分,空气和土壤等。只有了解和掌握各个环境因素对秧苗的作用,创造适宜的环境条件,满足秧苗生长的需求,才能培育出健壮秧苗。1 温度(1)气温一般地说,茄果类蔬菜在育苗期间最适宜的温度是白天保持在20-28摄氏度,夜间在12-18摄氏度,即日夜温差在10摄氏度左右。在这样的温差下,即有利于白天光合作用的需要,又防止晚间温度过高消耗过多的养分。瓜类秧苗要求的温度
Vegetable seedlings grow robustly only under suitable environmental conditions. These environmental conditions are mainly temperature, light, moisture, air and soil. Only by understanding and mastery of the environmental factors on the role of seedlings, to create the appropriate environmental conditions, to meet the needs of seedlings in order to cultivate robust seedlings. 1 Temperature (1) Air Temperature In general, the most suitable temperature for solanaceous vegetables during nursery is keeping at 20-28 degrees Celsius during the day and 12-18 degrees Celsius at night, that is, the temperature difference between day and night is about 10 degrees Celsius. In this temperature difference, which is conducive to the needs of photosynthesis during the day, but also to prevent excessive consumption of nutrients in the evening temperature is too high. Melon seedlings required temperature
