黑龙江省八五六农场位于牡丹江东南,穆棱河下游,是三江平原的一部分。地势低平,气候湿润,土壤主要为草甸白浆土,约占全场土壤面积的3/4以上,是开垦利用的主要对象。草甸白浆土是一种低产土壤,黑土层薄(12—16厘米),下为冷、瘦、板结的白浆层,养分贮量低,理化性质不良。改良的关键是结合施肥,逐步加深耕层,疏松土壤,最终达到消灭白浆层,以创造作物生育的良 One hundred and fifty-six farms in Heilongjiang Province is located in southeastern Mudanjiang, Muling River downstream, is part of the Sanjiang Plain. Low-lying, humid climate, the soil is mainly meadow albic soil, accounting for more than 3/4 of the total soil area, is the main target of reclamation and utilization. Meadow albacore is a low-yielding soil with a thin black soil layer (12-16 cm) and a cold, thin and compacted white pulp layer with low nutrient storage and poor physical and chemical properties. The key to improvement is fertilization, and gradually deepen the topsoil, soil loosening, and ultimately to eliminate the white pulp layer, in order to create a good crop fertility
