1) soil moisture movement
土壤水分运移
1.
Based on the principle and general momentum equilibrium equation of soil moisture,a realistic model of soil moisture movement in SPAC system is established in this paper.
基于土壤水动力学原理,建立了内陆河流域山前农田绿洲SPAC系统土壤水分运移的子模型。
3) water and nitrogen transport
土壤水分、氮素运移转化
4) soil water and salt transport
土壤水盐运移
1.
The soil water and salt transport were studied under 3 crop planting condition.
在田间试验条件下,采用正常灌溉定额和淋洗灌溉定额2种灌溉水平,对小麦、葵花、玉米3种作物进行了不同灌溉水浓度处理的灌溉试验,对3种作物种植条件下土壤水盐运移规律进行了研究。
5) soil water and nitrogen dynamics
土壤水氮运移
1.
A water and nitrogen management model(WNMM) was used to simulate the soil water and nitrogen dynamics in fluvo-aquic soil,with a view to establishing a scheme to optimize soil water and nitrogen in light of local climate and soil properties.
利用田间试验对WNMM模拟结果进行了校验,结果表明该模型能较好地模拟潮土地区的土壤水氮运移过程,农田蒸散量、土壤含水量和硝态氮含量的模拟值与实测值在α=0。
6) salt movement in soil
土壤盐分运移
1.
Experimental study on salt movement in soil under saline and fresh water alternate leaching;
咸淡水交替淋溶下土壤盐分运移试验
