《新疆农垦科技》编辑部: 我连地处柳沟地区,0—30厘米土层含盐量一般在2—5％,以硫酸盐为主,部分为氯化物硫酸盐。盐分在剖面上分布较均匀,地表化冻后常见盐结皮,一般无盐结壳。近几年来,这里土壤次生盐渍化逐年加重。我连靠近一家化工厂,该厂生产排出的糠醛渣堆积如山,职工们在肥源缺乏的情况下,想把这些糠醛渣当肥料施入承包地里,但我们这里从未有人用过。不知糠醛渣能否当肥料用?特向贵刊请教,望能给予答复。
“Xinjiang Agricultural Reclamation Science and Technology” Editorial Department: I was in the area of Liu Gully, 0-30 cm soil salt content is generally 2-5%, mainly sulfate, part of the chloride sulfate. Salinity distribution in the profile is more uniform, surface saltification after freezing common crust, salt-free crusts. In recent years, soil secondary salinization has been increasing year by year. I even came close to a chemical plant where the furfural residue produced by the plant was piling up. The workers wanted to put these furfural dregs as fertilizer in the contracted land in the absence of a fertilizer source, but none of us used it here. I do not know furfural residue can be used as fertilizer? Special to ask your advice, hope to give a reply.
