摘要: 研究了土壤水分对温室结果期嫁接和未嫁接黄瓜生长与生理特性的影响。结果表明: 适宜的
土壤水分有利于黄瓜植株生长和产量提高, 水分过高或过低均对生长发育不利; 叶片颜色、仰角与卷须可作为灌溉的形态指标; 叶片水势、细胞汁液浓度可作为灌溉的生理指标; 不同叶位叶片对土壤水分变化的敏感性不同, 可用下部功能叶片的形态与生理变化来判断灌溉时间与灌溉量; 嫁接与未嫁接黄瓜对土壤水分的反应规律相同, 但对水分的敏感程度存在明显差异。

Abstract: Effect of soil water on the growth and physiological characteristics of cucumber during fruit stage in greenhouse were studied in this experiment . The results showed that soil water status had something with the growth
and development of cucumber in greenhouse. Yield decreased and growing speed became slow due to over or deficit of soil water. Leaf color , leaf elevation and tendril appearance could be regarded as index to decide when and how much will be irrigated. Leaf water potential and leaf cytoliquid could also be regarded as irrigated index. Different leaves had different response to the change of soil water status. Grafted and non-grafted cucumber had different reaction on the same soil water conditions.
