Abstract:
In order to improve the quality of typical saline-alkali soil with plastic shed in the middle of Shaanxi,routine management (S0),biological organic fertilizer (S1),farm soil manure (S2),and corn stalk mulch (S3) for winter jujube in plastic shed of typical saline-alkali soil with plastic shed in Dali were established.Integrated fertility index (IFI) was adopted to assess soil fertility.In order to improve the quality of typical saline-alkali soil with plastic shed in the middle of Shaanxi.The results showed that improvement measures could decrease soil alkaline and salinity to different degrees.Bio-organic fertilizer (mushroom residue) and farm manure significantly reduced soil pH while corn straw mulching had no significant difference on soil pH.The desalinization rate was highest after corn straw mulching.Improvement measures overall increased soil nutrients and soil IFI,with different effects on various soil nutrients and fertility index.Bio-organic fertilizer (mushroom residue) and farm manure significantly increased soil nutrients and fertility.Take the depth of 0-20 cm as an example,cation exchange capacity (CEC),available nitrogen,soil organic matter,available phosphorus,available potassium,and IFI increased by 29.1%，262.4%，35.9%,596.8%,91.9% and 71.5%,respectively.Corn straw mulching increased to a certain degree soil fertility index in plough layer.However,the increasing of soil fertility in deep layer was limited.Therefore,the reasonable application of bio-organic fertilizer in the comprehensive improvement process of saline-alkali land of greenhouse in Guanzhong has a significant improvement effect on the overall soil quality.
