| 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... |
