赵光地区,位于黑龙江省中部,约当北纬48°、东经127°,北毗呼裕尔河,东接小兴安岭,南至赵光山顶,西连克山、拜泉,全区处于小兴安岭南麓之森林草原地带。本区荒地多,耕地开垦较晚,腐殖质含量高,土质肥沃。年雨量集中,土壤水份偏多,对作物生育产量影响较大。 为了进一步明确本区土壤在生产利用上存在的问题和解决办法及应采取的适宜耕作制度等,以发挥土壤的潜在肥力,提高产量。为此,特对本区土壤的利用情况、特性与分布规律进行调查,以作本区土地合理利用规划的依据。
Zhao light area, located in the central Heilongjiang Province, Jiao when latitude 48 °, longitude 127 °, north adjacent Hu Yu River, east Xiaoxing’anling, south Zhao Guang hilltop, west with Keshan, Baiquan, the region is located in the southern foot of Xiaoxing’anling The forest steppe zone. Many wasteland in this area, cultivated land reclamation later, high humus content, fertile soil. Concentration of annual rainfall, soil moisture is too much, a greater impact on crop yield. In order to further clarify the problems and solutions in the production and utilization of soils in the district and the suitable farming systems to be taken so as to bring the latent fertility of the soil into play and increase the output. To this end, special use of the area of soil conditions, characteristics and distribution of the survey to make plans for the rational use of land in the area basis.
