摘要

采用田间调查、土壤盆栽和大田试验相结合的方法

研究山西省主要类型土壤镁素供应状况及镁肥施用效果。结果表明

山西省主要类型土壤耕层(0-20cm)交换性镁含量在78.1～641.8mg/kg范围内

平均含量为255.1mg/kg。不同类型土壤交换性镁含量高低依次为潮土>褐土>栗褐土>石灰性褐土>黄绵土>褐土性土。土壤交换性镁含量与土壤主要化学性质密切相关。生物消耗试验表明

褐土和石灰性褐土的镁生物有效性较高

其次是褐土性土和黄绵土

栗褐土和潮土的镁生物有效性最低。与不施镁肥相比

施镁大豆增产2.77%～9.04%

玉米增产2.98%～10.21%;大豆籽粒粗蛋白含量提高4.56%～7.52%

玉米籽粒粗蛋白、总淀粉和总糖含量分别提高9.96%～15.36%

2.41%～6.42%和8.52～12.50%。相关分析表明

大豆籽粒中镁含量与籽粒产量、粗蛋白和粗脂肪含量呈显著线性正相关;玉米籽粒中镁含量与籽粒产量呈显著线性正相关

与粗蛋白含量呈曲线关系

而与粗脂肪含量呈现显著线性负相关。研究表明

山西省主要类型土壤交换性镁含量处于较高水平

不同类型土壤交换性镁含量及生物有效性存在显著差异

籽粒中镁与籽粒蛋白质和脂肪含...

Abstract

Experiments were conducted with the field investigation

pot and field experiments to study the magnesium supply status of main soil types and effects of Mg fertilizer on yield and quality of crops in Shanxi province.The results showed that the average content of exchangeable Mg in top soils(0-20 cm) of main types of soils in Shanxi province was 255.1 mg/kg

varied from 78.1 to 641.8 mg/kg.The order of exchangeable Mg content in different type soils was fluvo-aquic soil >cinnamon soil >chestnut-cinnamon soil ...
