| 摘要: |
| 应用蒸发蒸腾计算原理,求算了北京地区九个县(区)的玉米生育期的潜在蒸发蒸腾量及逐旬及全生育期的需水量。计算了玉米各主要生育阶段的日耗水强度及需水量。结合需水与降水重点讨论了以顺义、通县为代表的北京平原地区和以延庆为代表的北京山区的玉米需水规律及应采取的相应的生产措施和应注意的问题。 |

| Abstract: |
| This paper presents the calculating and analysis of water require merits with corn as material conducting in Beijing region every ten days.The whole growth period was measured and treated with penman formula in the computer. Based on the results,discusson and analysis were made on the relatio- ns of the rainfull and the rule of the rater requirement of corn and rainf- ull in Beijing region.Suggestions were made accordingly on count-measures to be taken for a reasonable irrigation of the corn crop in Beijing... |
