| 摘 要： | 寻求行之有效的盐渍化土壤改良措施,对于农业可持续发展具有重要理论和实践意义.采用盆栽试验,探讨了施用硫磺和喷施ALA对碱性盐土上冬小麦(Triticum aestivum L.)和玉米(Zea mays L.)幼苗生长发育及土壤性质变化的影响.结果表明,无论施用石膏、硫磺还是喷施ALA,对于小麦生长均有明显促进作用,其中硫磺效果更为明显;施用硫磺显著提高了后一茬玉米的出苗率,同时土壤中SO42-、Ca2+、Mg2-含量显著增加,但施硫降低土壤pH的作用较为有限;而施用ALA对土壤pH和盐分均无明显影响.这表明施加硫磺可以使盐渍化土壤的性质发生明显改变;ALA的效果则必须在作物苗期生长良好的前提下,通过提高作物自身的抗盐性来实现.

| Abstract: | The development of sustainable agriculture requires increased theoretical and practical knowledge about how to ameliorate saline soils. The objective of these short-term pot experiments was to investigate the effects of 5-aminolevulinic acid (ALA) and sulfur on soil properties and on the growth and development of winter wheat and maize. The experiment consisted of six treatments (1) sulfur added to the soil; (2) gypsum added to the soil; (3) ALA added to the soil; (4) foliar application of ALA to wheat and ... |
