大豆是鹤岗市农业生产的主要作物之一,大豆属低产作物,单产较低,近年来受市场价格的影响,效益差,大豆种植面积逐年缩减。本次试验根据鹤岗市地力评价结果,评价出适宜种植大豆的区域。从大豆不同适宜性耕地的地力等级的分布特征来看,耕地等级的高低与地形部位、土壤类型及土壤质地密切相关。高中产耕地从行政区域看,主要分布在中部、南部的乡镇,这一地区土壤类型以暗棕壤、草甸土、黑土为主,地势较平缓低洼,坡度较小;低产土壤则主要分布在西北部、北部的一部分地区,这些地区的耕地土层薄,质地差,地势起伏较大或者低洼,行政区域包括东方红乡、蔬园乡,土壤类型主要是白浆土,沼泽土等土壤类型。 Soybean is one of the main crops for agricultural production in Hegang City. Soybean is a low-yielding crop and has a low yield. In recent years, soybean market has been affected by market price, resulting in poor efficiency and a reduction in soybean acreage. The test according to Hegang City evaluation results to evaluate the appropriate planting soybean area. From the distribution characteristics of soil fertility levels of different suitability cultivated land of soybean, the level of arable land is closely related to topography, soil type and soil texture. High-yielding arable land from the administrative region, mainly in the central and southern townships, the soil types in this area are dark brown, meadow soil, black soil dominated, relatively flat low-lying, slope is small; low-yielding soil is mainly distributed in In the northwestern part and the northern part of the country, the cultivated land in these areas is thin and poorly textured with large or low topography. The administrative areas include Dongfanghong and Vegetable Townships. The soil types are mainly white soil and marsh soil .
