摘要
【目的】揭示长期以来镁肥施用对作物产量及矿质元素吸收影响的综合效应。【方法】利用收集已公开发表的文献数据,获得符合要求的43篇文献,采用Meta-analysis定量分析施镁对作物产量及矿质元素吸收的综合效应。【结果】与不施镁肥相比,施镁能够提高水稻、烤烟、小白菜、玉米、马铃薯、番茄等作物的产量,其综合效应均值为0.063 4;施镁能普遍促进作物对N、P、K、Mg等矿质元素的吸收,其综合效应均值分别为0.021 1、0.079 4、0.007 6、0.165 1;对Ca吸收的整体影响效应为负值,综合效应均值为-0.106 9。【结论】酸性至微碱性土壤上镁肥的施用对于提高作物产量,促进作物对矿质元素的吸收具有重大意义。
【Objective】To reveal the long-term effects of magnesium fertilizer application on crop yield and mineral element absorption.【Method】This study collected published literature data and 43 articles that meet the requirements were obtained. Meta-analysis was used to quantify the combined effect of mag-nesium application on crop yield and mineral element absorption.【Result】The results show that magne-sium application can increase the yield of rice,flue-cured tobacco,pakchoi,corn,potato,tomato and other crops compared with no application of magnesium fertilizer. The average of the combined effect of the magnesium application is 0.0634. Magnesiumcan generally promote the absorption of N,P,K,Mg and other mineral elements in crops. The average of the combined effect of the magnesium application is 0.021 1,0.079 4,0.007 6,0.165 1. However,the overall effect of magnesium application on Ca absorp-tion is negative,and the combined effect average is -0.106 9.【Conclusion】The application of magnesium fertilizer on acidic to slightly alkaline soil has great significance for increasing crop yield and promoting the absorption of mineral elements by crops.
