一、温度温度是秧苗生长发育的基本条件,温度包括气温和土温两个方面。秧苗生长发育的不同阶段,对气温的要求有所不同。一般地说,在正常生长的情况下,果菜类蔬菜在育苗期间,最适宜的温度是白天保持20—25℃之间,夜间保持在12—18℃之间。瓜类要求比茄果类高2—3℃,即日夜温差在10℃左右。阴雪天气
First, the temperature Temperature is the basic conditions for seedling growth and development, temperature, including temperature and soil temperature in two aspects. Seedling growth and development of different stages, the temperature requirements are different. In general, under normal growth conditions, the most suitable temperature for fruit and vegetable vegetables during nursery is to maintain between 20-25 ° C during the day and between 12-18 ° C during the night. Melons require higher than the solanaceous 2-3 ℃, the temperature difference between day and night at about 10 ℃. Cloudy weather
