生化黄腐酸土壤改良剂对菜田盐碱土壤理化性质的影响

Effect of Biochemical Fulvic Acid Soil Modifier on Physical and Chemical Property of Saline Soil in Garden

菜田盐碱土壤施用一定量的生化黄腐酸土壤改良剂不仅具有较明显的改碱效果,而且可以明显改善盐碱土壤的结构,降低盐分含量。其最佳施用量为2%左右,对盐渍化程度高的土壤,施用量适当加大效果更好。施用时间越长,碱性菜田土壤的改良效果越好。

Biochemical fulvic acid soil modifier not only could improve not only component but also structure of saline soil obviously. The best proportion was 2 % but the effect was better when the dosage was increased to high degree saline soil. The effect of improving was better if the time of using the modifier was longer.
