黄瓜是塑料大棚蔬菜生产的最主要品种之一,它们生长的好坏与产量的高低,受综合条件的影响,但温度起主导作用。所以在黄瓜生长中保持棚内的适宜温度,是黄瓜栽培中一项极为重要的措施。 第一,要知道黄瓜在不同时期对温度的不同要求。播种至出苗,白天气温保持在30℃左右,夜间气温和地温,均要在18C～20℃之间;定植期,要求10厘米地温在10℃以上,气温白天在20℃～ Cucumber is one of the most important varieties of vegetable production in plastic greenhouse. The quality of their growth and yield are affected by the comprehensive conditions, but the temperature plays a leading role. Therefore, maintaining the greenhouse cucumber in the appropriate temperature is cucumber cultivation is an extremely important measure. First, we must know the cucumber in different periods of different temperature requirements. Sowing to emergence, the temperature during the day to maintain at about 30 ℃, night temperature and ground temperature, should be between 18C ~ 20 ℃; planting period, 10 cm above ground temperature required at 10 ℃, temperature during the day at 20 ℃ ~
