白浆土分岗地白浆土、平地白浆土和低地白浆土,是低产土壤。白浆土剖面构造分三层:第一层表土是黑土,厚十多厘米,土质较好;第二层心土是白浆层,厚二十多厘米,有机质和养分含量低,是瘠薄土层;第三层底土是蒜瓣土,土质硬,叫做“铁板泥”。白浆土性质不好,土质粘重,不渗汤,浆冷,不发小苗;怕旱、怕涝、养分低,缺少速效磷。岗地水土流失,低地易出现内涝。 一、施草炭。经过腐熟的草炭粉碎后直接施用,亩施一至二万公斤,增产显 Albite sub-post white soil, white ground and lowland white soil, is a low-yielding soil. The structure of albic soil is divided into three layers: the first layer of topsoil is black soil with a thickness of more than 10 cm and the soil quality is better; the second layer of earth is a white pulp layer with a thickness of more than 20 cm and low organic matter and nutrient content, Layer; the third layer of soil is clover soil, soil hard, called “iron mud.” The quality of albacore is not good, the soil is sticky, the soil does not penetrate the soup, the pulp is cold and no seedlings are found; afraid of drought, fear of waterlogging, low nutrient content and lack of available phosphorus. Gangti soil erosion, low waterlogging prone. First, the grass charcoal. After the maturity of charcoal crushed directly applied, Mushi Shi one to twenty thousand kilograms, increase significantly
