- Title:
- The Application of the Neutron Probe in the Research of Farmland Soil Moisture of Dryland
- Keywords:
- the device of neutron microzone model; evaporation among plants in farmland; leaf area index; crop transpiration
- 分类号:

- 摘要:
- 采用中子微区模拟装置测量旱地玉米农田棵间蒸发的结果表明，本试验装置实用可行.晋西棵间蒸发量占降水量（510mm）的54%以上；棵间蒸发与蒸腾的比值同叶面积指数呈负相关，玉米产量与作物蒸腾呈正相关.
- Abstract:
- The device of the neutron microzone model was applied to inspect the evaporation capacity among plants in dryland corn farm land.The results showed that the device was practical.In the west ernregion of Shanxi province the evaporation capacit yamong plants accounts for more than 54% of the annual precipitation rain capacity(510mm).The ratio of evaporation to transpiration among plants was negatively correlated with leaf area index,and yield was positively correlated w ith crop transpiration.
