【摘要】 通过温室盆栽试验,研究了不同管理调控措施(有机肥、中量石膏、大量石膏、中量微生物菌群(EM)和大量微生物菌群以及有机肥与各调理剂的组合措施)对苏北滩涂盐碱地土壤质量改善的影响。结果表明:各调控措施均有利于滨海盐碱土壤肥力的改善、大麦的生长,并综合呈现出组合措施优于单项措施、石膏优于EM的趋势。有机肥与土壤调理剂的配合施用可有效改善滨海盐碱地土壤质量,提高作物产量。更多还原

【Abstract】 The effects of different adjustment measures on soil quality and crop growth were studied by pot experiment in greenhouse,including organic fertilizer,gypsum,effective micro-organisms(EM),organic fertilizer combined with gypsum or EM.The results showed that all the treatments improved soil fertility and barley growth,the effects of comprehensive measures were better than individual measures,and gypsum was better than EM.Therefore,new cultivation pattern of organic fertilizer combined with soil amendments is recommended for soil quality and productivity improvement of the saline-alkali soil.更多还原
