神木试区的土壤资源

本流域处鄂尔多斯台地的边缘，土壤类型有发育在黄土母质上绵沙土、硬黄土和红黄土；有发育在沙漠上的风沙土；还有淤土等。因成土母质不同，土壤物理—水分性质，化学性质和农艺特性有明显差异。据绵沙土、硬黄土、红黄土和风沙土的特性，进行农业利用，改良时主要沙掺粘和增施磷肥，微量元素等。从本流域土壤类型分布看，有交错带的特征。

The Soil Resource in the Shenmu Experimental Area

The Liudaogou watershed is located in the southern fringe of the Oerduos platform. The soil types are mein sand soil, hard loessal soil and red loessal soil on the loessal mather material, and aeolian sand soil on the desert and warp soil et al. Owing o different mather material of soil formation, soil physical-water proerty, chemical property and agromical character have obvious difference. According to characteristics of the mein sand soil, hard loessal soil, red loessal soil and aeolian sand soil, ways of soil improvement is that clay is mixed into sand and phosphatic fertilizer and micro-element etc. is applied into soil. From views of distribution of soil types in the Liudaogou watershed, the Liudaogou watershed has characteristics of transition zone.
