| 摘 要： | 利用卡庆斯基制、美国制、中国制3种土粒分级标准对张家口葡萄产区的30个采样点进行土壤质地命名,并通过对比分析得出中国制是该区最适的土壤质地分类方法。现对吸湿水含量与土壤各粒级微粒百分含量的关系做了探测性研究,得出吸湿水和土壤中小于0.01 mm的粒径含量之间拟合曲线方程为:Y=20.272e0.207x,可根据此方程应用卡庆斯基制确定土壤质地;吸湿水和土壤中1~0.05 mm0、.05~0.002 mm粒径含量的拟合曲线方程分别为:y=22.018x2-105.323x+156.381,y=-18.304x2+86.495x-49.536,又可根据这2个方程利用美国制确定土壤质地名称。这些为用简易方法鉴定土壤质地类型提供科学依据。

| Abstract: | Using the system of Kachinsky classification,American and Chinese of soil texture,the author named the soil texture of 30 sampling points in grape producing area of Zhangjiakou.Through the contrastive analysis,the author found Chinese system was the most suitable soil texture for this area.This article had also done the survey research to hygroscopic water content and the soil various grades particle percentage's relations,obtains the fitted curve equation between hygroscopic water and particle smaller than... |
