一、养分现状分析乌苏市土壤在生物气候和水文地质条件下,形成了灌耕土、潮土、灰棕漠土、草甸土、盐土共5类,其中农业土壤有灌耕土、灰棕漠土和潮土3类。1.灌耕土灰漠灌耕土属,此类土熟化程度较高,在原有自然土壤灰漠土上发育起来的灌耕土,面积约1.2万公顷,占调查面积的16.7%,主要分布在甘河子镇、八十四户乡、哈图布呼镇、皇宫镇、九间楼乡等老耕地上,灌耕熟化层厚度在30厘米以上,具有良好的粒状或团块状结构。土壤养分含量:有机质平均含量
I. Analysis of Nutrient Status In soils under biological climate and hydrogeological conditions, the soil of Wusu County has formed five types of irrigated soil, alluvial soil, gray-brown desert soil, meadow soil and saline soil. Among them, agricultural soil includes irrigated soil, Soil and soil 3 categories. 1. Irrigated soil Gray desert irrigated soil belongs to this kind of soil with high degree of maturation. The irrigated soil developed on the original natural soil gray desert soil has an area of about 12,000 hectares, accounting for 16.7% of the surveyed area, mainly distributed in Ganhe Sub-town, eighty-four rural, Hatu Bughu town, Royal Palace town, nine buildings and other old land, irrigation and curing layer thickness of 30 cm or more, with a good granular or lumpy structure.
