摘  要:
通过小区试验研究了白三叶草和翦股颖草两种草坪的蒸发蒸腾导致的土壤含水量变化,以及和灌溉后天数之间的相互关系。结果表明,两种常见的绿化用草中,翦股颖的蒸发蒸腾速率明显高于白三叶。翦股颖种植区0~20和20~40 cm土层中水分变化趋势吻合,而白三叶草种植区土层含水量为20~40 cm,低于0~20 cm,说明三叶草土壤水分损失以植物蒸腾作用为主,而翦股颖叶片较小,水分损失以土壤的蒸发作用为主。本研究形成的精细灌溉制度,将全年的灌溉定额合理分布在全年各个月份,有效提高水分利用效率。

摘  要:
The relationship between plants transpiration and water content in soil and days after irrigation were studied with plants of white clover and agrostis bentgrass through plots trial in field.The results showed that the transpiration rate of agrostis bentgrass was higher than that of white clover.Tendency of soil water content in the layers 0-20 cm and 20-40 cm with agrostis bentgrass was same while with white clover soil water in layer 20-40 cm it was lower than in layer 0-20 cm.The main reason was that the leaf area of white clover was larger than that of agrostis bentgrass.This research would help to form a accurate irrigation system distributing the water to every month in a year,increasing water using efficiency.
