摘要: 为了研究不同改良物料(脱硫石膏、草碳、腐殖酸)单一施用与不同配比在盐碱土壤上对作物产量与土壤理化性质的短期改良效果,于2014—2015 年在山东乐陵地区进行了8 处理3 重复的随机区组试验。结果表明:第一季小麦相比未改良处理,脱硫石膏、有机物料单一施用及不同配比均没有显著增加小麦产量。玉米季时,脱硫石膏与腐殖酸单一施用与其1:2 组合与未改良处理在玉米产量上没有显著性差异,但脱硫石膏与腐殖酸1:1 组合实现玉米增产40%。改良物料1:1 组合措施显著提高了玉米籽粒的氮与钾浓度,同时降低土壤pH 0.5 个单位。土壤中的速效钾含量显著提高,交换性钠的含量显著降低,维持了土壤溶液中钾钠比的平衡。因此,盐碱土短期的改良过程中,脱硫石膏与腐殖酸1:1 组合施用,对于改良土壤盐碱具有一定的应用前景。

Abstract: In order to study the short- time improvement effect of different application models (single and combination) of different materials (desulfurization gypsum, grass carbon and humic acid) on crop yield and grain nutrient content in saline-alkali soil, a randomized block experiment with eight treatments and three repeats was conducted in Laoling, Shandong from 2014 to 2015. The results showed that compared to the treatment without improvement of the first season wheat, single application or different combinations of desulfurized gypsum and organic materials did not significantly increase wheat yield. Compared to the treatment without improvement of maize, single application or 1:2 combination of desulfurized gypsum and humic acid did not significantly increase maize yield, while 1:1 combination increased maize yield by 40%. 1:1 combination treatment increased N and K contents in maize kernel significantly, decreased pH value by 0.5 unit, increased available K content and decreased exchangeable Na content, which could maintain the balance of K/Na in soil solution. 1:1 combination of desulfurized gypsum and humic acid has application prospect in short-time improvement of saline-alkali soil.
