| 摘 要： | 对滴灌条件下新乡青茄全生育期的棵间蒸发规律进行了试验研究,结果表明,茄子在整个生育期相对土壤蒸发的变化曲线均呈脉冲状。相对土壤蒸发强度与表层土壤含水率和作物叶面积指数之间均呈现良好的指数函数关系,灌溉后3 d内相对土壤蒸发强度较大,受大气蒸发力影响明显。综合考虑气象因子的影响程度,太阳辐射是棵间土壤蒸发的主要影响因素。 |

| Abstract: | The experiment on top soil evaporation disciplinarian of eggplant under drip irrigation was carried out.The results showed that the daily variation of relatively soil evaporation presented pulse curve in whole in growth period.There was a good exponential function relationship between relatively soil evaporation intensity and surface soil water content and leaf area index.Relatively soil evaporation intensity was comparatively great within 3days after irrigation,and it was evidently influenced by atmosphere evaporation intensity.Results from the experiment indicated that the change of surface soil evaporation was positively related to solar radiation in the greenhouse. |
