摘要

试验研究表明

煤矸石沙障对沙地土壤有明显的改良作用

使沙地土壤中细粒物质增加

土壤水分含量提高

土壤结构发生改变 ;土壤中有机质、全 N、速效 P、速效 K含量显著增加

分别是流沙对照地的 2 .6 5

1.2 4倍。同时

分析结果表明

障蔽规格对土壤养分、水分的影响较显著

而矸石粒径影响不显著。

Abstract

The results showed that coal gangue obstruction can greatly improve the soil properties of sandy land

such as the silt content and soil moisture can be sharply increased

the soil structure can be improved. The soil organic matter

total N

available P

K can be increased by 2.65

2.66

1.30 and 1.24 times of the control respectively. In addition

the size of the coal gangue has notable effects on the soil fertility and moisture.
