对温度的要求:厚皮甜瓜要求温暖而昼夜温差大的环境,它极不耐寒,遇霜即死。适温白天为25~30℃,夜温为16~18℃。 气温的日差大小对甜瓜的果实发育及糖分的转化积累有直接关系,气温日差在11~20℃时,有利于糖分积累。 不同品种对低温的忍耐程度不同,日光温室反季节栽培要注意选择耐低温、耐湿、早熟的品种。 对光照的要求:甜瓜植株生长发育要求每天有10~12小时的日照。在每天12小时日照的条件下,
The temperature requirements: muskmelons require warm and large temperature difference between day and night environment, it is extremely cold, frost that death. Suitable temperature during the day 25 ~ 30 ℃, night temperature 16 ~ 18 ℃. The temperature difference between the size of the melon fruit development and sugar accumulation is directly related to the accumulation of temperature difference between 11 ~ 20 ℃, is conducive to sugar accumulation. Different varieties of low temperature endurance of different degrees, greenhouse cultivation in the season should pay attention to select low temperature, humidity, precocious varieties. Requirements for light: melon plant growth and development requirements of 10 to 12 hours a day of sunshine. Under the conditions of 12 hours daily sunshine,
