- Influence Factors on Soil Wetting Front under Point Drip Irrigation 滴灌点源入渗湿润锋影响因子的研究
- soil wetting front 湿润体
- The wetting front moved nearly parallel to the soil surface, and its length could be described by a power function of time, when the distribution of initial soil water was uniform. 当初始含水量分布均匀时,降雨入渗过程中湿润锋面几乎平行坡面运移,湿润锋深度与时间的关系可用幂函数描述。
- The wetting front simulated an ellipsoid in irrigation process, but it is changed hemisphere after irrigation. 在灌水过程中,湿润锋水平扩散速度总大于垂直入渗速度,湿润体为平卧的椭球体。
- It is also showed that the depth of wet front in CFI is deeper than those in AFI and FFI. 对 3种灌水方式湿润锋到达深度的研究表明 ,常规灌溉的湿润锋到达深度明显大于固定隔沟灌溉和交替隔沟灌溉。
- The results show that the movement of wetting front of slightly salty infiltration is deeper under the same time condition,or the time is shorter to move to the same depth. 研究结果表明,微咸水入渗的湿润锋在相同的时间内运移深度更大,或者湿润锋运移到相同的深度时微咸水所用的时间更短。
- I can not remember this is the severalth time in the wet front pieces of Chinese jacket of tears of instant in a trance clearly, all cannot help each time, the frightening sidelong glance each time, why does it appear so easily? 我记不清这是第几次在恍惚的刹那泪湿衣襟了,每次都是情不自禁,每一次都怕人侧目,为什么它这么轻易而出呢?
- Results showed that to compare with conventional furrow irrigation(CFI), lateral infiltration of alternative furrow irrigation(AFI)is more obvious. Due to its wet front depth is less than CFI, it can decrease water deep percolation. 结果表明 ,交替隔沟灌溉与常规灌溉相比 ,水分的侧向入渗比较明显 ,由于其湿润锋到达深度小于常规灌溉 ,因此 ,交替隔沟灌溉可以减少土壤水分的深层渗漏 ;
- During the budding time, keep the soil wetness but not over, how ml should it need is based on the soil-dryness or wetness; keep ventilation. 在种子发芽周期里需保持盆土湿润,不宜过湿,视土干湿而定浇水量;保持通风,通气。
- During the budding time,keep the soil wetness but not over,how ml should it need is based on the soil-dryness or wetness;keep ventilation. 在种子发芽周期里需保持盆土湿润,不宜过湿,视土干湿而定浇水量;保持通风,通气。
- horizontal/vertical wetting front 水平/垂直湿润锋
- The related results are close to those of IREX96. The SiB2 was demonstrated with automatic weather station(AWS) data and could be used to estimate the energy components, CO 2 flux, soil wetness and soil temperature profile. CO2 通量的模拟结果与 1 996年国际稻田试验结果相似。 该研究为利用自动气象站网的资料估计各站能量收支、CO2 通量、土壤水分平衡、以及土壤温度廓线提供了新证据
- Some plants push their roots deep into the soil. 一些植物的根深深长入土中。
- Distribution rule of soil moisture and simulation model in wetting front under non-pressure irrigation 无压灌溉土壤湿润体含水率分布规律与模拟模型研究
- Estimation Model of Soil Surface Trickle Infiltration Vertical Wetting Front Based on Horizontal Visual Wetting Front 基于地上可视湿润距离的地表滴灌入渗深度估算模式研究
- Such crops won't grow in limy soil. 这类作物不能在石灰质的土壤中生长。
- What shall we grow in this alkaline soil? 我们应该在碱性土壤里种什么?
- There are a lot of worms in the soil. 泥土中有许多蠕虫。
- Water has permeated (through) the soil. 水已渗遍那片土壤。
- There are some clods of soil on the mat. 垫子上有些土块。
