大棚黄瓜连作导致生长发育不良，产量降低，尽管原因较多，但主要原因是来自土壤，作者曾对产生连作障碍的土壤理化性状［１］、土壤微生物区系［２］进行过研究，结果认为，土壤微生物和土壤盐渍化分别是连作障碍的主要因素之一。关于土壤生物学因素（包括土壤微生物）对连作 The cucumber continuous cropping resulted in poor growth and yield reduction, though the reasons were mostly due to the soil. The authors studied the soil physical and chemical properties [1] and the soil microbial flora [2] Soil microorganism and soil salinization are respectively one of the main factors of continuous cropping obstacle.
