摘要
为筛选黄瓜潮汐灌溉育苗适宜的参数,以超美特为试材,采用L_9(3~3)正交试验设计,分析顶部洒水灌溉和潮汐灌溉2种方式下的基质性质、灌溉指标及黄瓜生长生理变化。结果表明,与顶部洒水灌溉相比,潮汐灌溉可节水11.6%~79.4%。对黄瓜植株生长和光合速率起主要作用的是灌水高度,对根系生长起主要作用的是浸盘时间,对基质电导率和用水量影响最大的是灌溉频率。综合来看,灌水高度2 cm、浸盘时间1 h、灌溉频率2 d·次^(-1)组合可以作为黄瓜潮汐灌溉育苗管理的参考范围。
To screen the optimum parameters for cucumber seedling with ebb and flow irrigation,Chaomeite cultivar was selected as study material,and orthogonal experimental method（L9） was adopted to explore the growth and physiological characteristics of cucumber seedlings,matrix properties,and irrigation index under either top sprinkling irrigation or ebb and flow irrigation. It was shown that ebb and flow irrigation could save water by 11. 6%-79. 4%as compared to top sprinkling irrigation. Irrigation height was the key role affecting the growth index and photosynthetic rate of cucumber,while soaking time played a key role in the growth of root,and the irrigation frequency was the most important factor affecting EC and water consumption. To summarize,the combination of 2 cm irrigation height,1 h soaking time,and 2 d per time irrigation frequency seemed reasonable for cucumber under ebb and flow irrigation.
