生菜是一种耐低温较强的作物,短时间能忍耐-5℃低温,而且生育期短,生长迅速,从育苗到收获50～60天,根据这一生理特点,我们在大棚主栽品种前,抢种一茬生菜,可有效的提高单位面积产量,和大棚利用率,经济效益高。这几年我们在大棚生菜栽培上积累了经验。主要栽培技术如下:
Lettuce is a low temperature resistant crops, a short time to endure -5 ℃ low temperature, and short growth period, rapid growth, from seedling to harvest 50 to 60 days, according to this physiological characteristics, we planted in the greenhouse before the species , Grab a crop of lettuce, can effectively improve the yield per unit area, and the utilization of greenhouses, high economic efficiency. In recent years, we have accumulated experience in the greenhouse lettuce cultivation. The main cultivation techniques are as follows:
