摘要

坡耕地是土壤侵蚀发生的主要策源地,有效控制坡耕地的土壤侵蚀才能控制面源污染,促进土壤结构的优化。分析了应用水土流失防治新材料W-OH固化剂后,土壤的抗蚀效果及对大豆和玉米2种农作物植株高度、净光合速率和气孔导度的影响。结果表明:大豆和玉米对W-OH的响应存在差异,且同种作物的生长在不同浓度W-OH溶液处理下也存在差异。总体表现为:喷施W-OH溶液后土壤的抗蚀能力增强,低浓度W-OH溶液处理下作物生长较好,高浓度处理下的作物生长受抑制或死亡。因此,在W-OH的应用过程中应结合具体作物设计合理的喷施浓度。研究成果将为后续新材料在坡耕地水土流失防治中的应用提供参考依据。
        Slope farmland is the main source of soil erosion. Non-point source pollution will be reduced and soil structure will be improved if soil erosion of slope farmland is controlled effectively. In this study, the performance of soil against erosion and the growth indexes of soybean and maize(plant height, maximum net photosynthetic rate and stomatal conductance) under different W-OH concentrations were investigated. Results showed that the response to W-OH solution treatment was different between soybean and maize; soybean and maize growth varied depending on the concentration of W-OH. In general, W-OH solution treatment enhances the resistance of soil against erosion. In the presence of low W-OH concentration, soybean and maize grew better; while in high W-OH concentration, the growth of soybean and maize were inhibited or they even died. Therefore, reasonable concentration should be designed when W-OH solution is applied to slope farmland. The research finding will provide reference for the follow-up application of new materials to water and soil erosion prevention.
