摘要
脱硫副产物中含有丰富的S、Ca、Si等,这些物质是植物必需或有益的矿质营养。脱硫副产物能降低土壤容重,改善土壤结构,增加土壤通透性,改善土壤水分物理性状,中和土壤碱性,降低土壤pH值和碱化度,降低土壤的全盐量,从而达到改良碱化土壤的作用。有利于土壤生物活动和作物正常生长,使得作物产量大幅度提高。
Desulphurization by - product are rich in S, Ca, Si, etc. which are essential and useful for crops. Applying desulphurization by- product properly can reduce soil bulk density, improve soil structure, increase soil permeability and improve the physical properties of soil moisture, reduce pH, ESP, TDS and improve the sodie soil physical and chemical properties. It is conducive to soil biological activity and crop growth. The crop yields will be increased greatly.
