| 摘 要： | 本文主要论述了以肇州县为代表的松嫩平原地区喷灌小麦土壤耗水规律及喷灌轮喷期的确定问题．通过大量实测资料分析、归纳、得出这一地区喷灌小麦土壤深度不同，耗水率也不一样，其规律是，随土层加深，耗水率递减。对喷灌轮喷期的研究，国内外研究甚少，本文以独特方法，主要以作物适宜含水率的上限、下限差为基本理论依据，导出轮喷期的半经验公式，得出这一地区小麦轮喷期可在６－８天．

| Abstract: | The problem of determination about the law of soil consuming moisture of sprinkling irrigation wheat and sprinkling irrigation-Rotation-Rotation spraying on Son-Nen plain embodied in Zhao Zhou county is illustrated. According to a lot of practical data, we analyze, reason and conclude that the soil of sprinkling irrigation wheat has different depth, it has different weter consumption rate, and the law is, the deeper soil is, the lower water consumption rate is. It is seldom studied about this problem of sprinkling irrigation -rotation spraying at internal or external Using unique methods, basing on the theory between the different figure of high hot and low limit, which are suitable for water content rate of crop growth. We conclude the semi-experienced formula or rotation spraying, that is to say, which can last 6-8 days for the wheat rotation spraying in this area. |
