soil particle size meaning in Chinese
土粒大小
Examples
- A preliminary study was carried out on the method of acquiring parameters for soil dual - porosity model and the analysis for the simulation of soil nitrate leaching by dual - porosity model . the feasibility and experimental conditions of soil particle size analyzing by the laser particle - size analysis was discussed , based on the comparison results of nine soil samples by the laser particle - size analysis and traditional pipette and sieve analysis
本文初步探讨了土壤两域模型的参数获取方法及两域模型应用于土壤硝酸盐淋洗的模拟分析,为进一步研究优先流以及分形理论在土壤溶质(包括养分)运移研究中的应用打下基础,以更准确地模拟和预测农田土壤硝酸盐的淋洗,为农田水肥优化措施提供依据。 - Knowledge and conclusions educed from the study are following : firstly , actual behaviors of soil erosion on affecting soil quality have been described . comparisons of landform measurements on the spots , and results of physical and chemical analyzing indicated that micro - iandform , proportions of soil particles sizes , and contents of soil carbon and nutrient have differences of spatial distribution under different conditions of fertilization development , cultivation , slope , and soil erosion management , which are closely related to intensities of soil erosion and sediment deposition
研究中,在前人基础上紧跟研究前沿,主要得出如下成果和创新点:一、明确了侵蚀作用影响土壤碳和养分含量的具体表现:经过实地测量、采样颗粒分析和养分分析,结果表明,在不同培肥、不同耕作、不同坡度以及不同侵蚀控制条件下,受侵蚀及堆积作用强弱的影响,微地形形态、土壤颗粒组成、碳和养分含量在空间上都可能出现较大的分布差异。
