| 摘 要： | 我们确定甘肃省的景泰、皋兰和榆中县分别为滩羊的中心产区、一般产区和过渡产区,并以武威县为对照区。除对各区的土壤含硫量作了测定以外,还测定了 pH 值及 N、P 和总盐分的含量。测定结果指出,中心产区的土壤含硫量为对照区的3—4倍,一般产区为对照区的28倍。不同产区的土壤 pH 值相等,均在8.5—9.5之间。但产区间总盐分含量差异很大,而且不同产区的含硫量和总盐分含量间呈正相关。

Study of Ecology and Methods of Selection of Tan-sheep(Ⅰ)Determination of Sulphur Content and Other Items in the soil in various Areas of Tan-sheep in Gansu province |

| Abstract: | We have taken Jingtai,Gaolan,and Yuzhong counties of Gan u Province as central,general and interim producing areas of Tan- sheep respectiv-ely,and Wuwei as their contrast. Besides sulphur Content,we have also determined the pH,and N, P,and total saline content in the soil with normal methods. The results have shown that the sulphur content in the central and general areas is 3-4 and 28 times as much as that of the contrast respeetively. The soil pH in various areas is the same,with its value within s8.5-9,5.But the total saline content in different areas varies sgreatly.The total sulphur content and total saline content in variou are positively interrelated, |
