摘要

通过田间调查取样和室内分析，研究了水稻种植（5~30年）对吉林省西部苏打盐碱土的改良和培肥效果。结果表明：与种稻前的荒地土壤相比，种稻后土壤的pH、全盐量、交换性钠、碱化度、CO32-、HCO3-、Cl-、Ca2+、Na+和<0.053 mm粉黏粒含量显著降低，而SO42-、总有机碳、水溶性有机碳、胡敏酸碳、富里酸碳、碱解氮和2~0.25 mm大团聚体含量显著增加）同时，有机碳组成中的烷基碳和烷氧碳含量增加，而芳香碳和羰基碳含量降低，脂族碳/芳香碳比值增加，而烷基碳/烷氧碳和疏水碳/亲水碳比值降低）随种稻年限的延长，以上变化规律通常表现的更为明显。上述结果表明，种稻不仅能够降低土壤碱性和盐分含量，而且有助于提高土壤有机碳的含量和品质，以及改善土壤结构性，因此是改良和培肥苏打盐碱土的有效方式。

Abstract

The ameliorative effects of rice cultivation (5~30 years) on soda saline-alkali soil in western Jilin Province of northeast China were studied through field survey and laboratory analysis. The results showed that compared with the virgin soil before cultivating rice

the pH value and the contents of total salt

exchangeable sodium

alkalization degree

the contents of CO32-

HCO3-

Cl-

Ca2+

Na+ and silt plus clay (<0.053 mm) fractions of soil decreased significantly after rice planting

while the contents of SO42-

total organic carbon

water soluble organic carbon

humic acid carbon

fulvic acid carbon

alkali-hydrolyzable nitrogen and large aggregates (2~0.25 mm) in soil increased significantly. At the same time

the contents of alkyl carbon and alkoxycarbon in organic carbon increased whereas those of aromatic carbon and carbonyl carbon decreased in soil

resulting in an increase of the ratio of aliphatic carbon/aromatic carbon and a decrease of the ratios of alkyl carbon/alkoxycarbon and hydrophobic carbon/hydrophilic carbon. The above changes were usually more obvious with the extension of the rice planting years. The results indicated that rice planting could not only reduce soil alkalinity and salt content

but also increase the content and quality of soil organic carbon and improve soil structure. Therefore

rice planting was an effective way to ameliorate soda saline-alkali soil.
