通过田间试验,验证各类腐殖酸肥料抑制次生盐渍化效果,研究不同土壤和气候条件下盐分在土壤中的分布规律为抑制博州棉区次生盐渍化提供科学依据。施用腐植酸后土壤速效磷增加幅度达到2.43%-53.84%,腐殖酸含量18%的有机肥,腐殖酸含量6%的氨基酸肥料,黄腐殖酸含量15%的水溶肥分别比对照增产21.9%,14.7%,3.6%。
Field experiments were conducted to verify the effect of various types of humic acid fertilizer on secondary salinization and to study the distribution of salinity in soil under different soil and climatic conditions in order to provide a scientific basis for the suppression of secondary salinization in Boshu cotton area. After application of humic acid soil available phosphorus increased by 2.43% -53.84%, humic acid content of 18% organic fertilizer, humic acid content of 6% amino acid fertilizer, yellow humic acid content of 15% of water-soluble fertilizer, respectively, than the control 21.9%, 14.7%, 3.6%.
