摘要:

为探明油菜-早稻-鲜食秋大豆(油稻豆)新三熟轮作模式对土壤理化性质和水稻微量元素的影响,促进该轮作模式下栽培技术的完善与规范化发展,开展了田间定位试验。试验设置早稻-晚稻连作和油-稻-豆轮作2个处理,分析不同处理对土壤基本理化性质以及水稻微量元素含量的影响。结果表明,与传统连作相比,连续2 a油-稻-豆轮作后的土壤pH值显著降低,碱解氮、速效钾含量显著上升,而阳离子交换量、容重及有机质、全氮、全磷、全钾、有效磷含量无显著差异。连续2 a油-稻-豆轮作后,土壤铁、锰、锌、铜和镉总含量无显著差异,但有效态含量均显著增加。连续2 a油-稻-豆轮作后,早稻地上部稻草和糙米镉含量均显著增加。本试验条件下油-稻-豆轮作能够有效提升土壤有效养分水平,但同时会显著降低土壤pH值,并且存在引发早稻重金属镉污染的风险。

Abstract:

To investigate the effects of the new triple-cropping rotation model of rapeseed-rice-bean on soil physicochemical properties and rice trace element content, and to promote the improvement and standardization of cultivation techniques for this rotation model, a field positioning experiment was conducted. Field positioning experiment was conducted with two treatments: continuous early rice-late rice cropping and rapeseed-rice-bean rotation, analyzing the effects of different treatments on basic soil physicochemical properties and rice trace element content. The results showed that, compared with traditional continuous cropping, the soil pH value significantly decreased after two years of rapeseed-rice-bean rotation, alkali-hydrolyzable nitrogen and available potassium content increased significantly,but no significant difference was observed in cation exchange capacity, bulk density and organic matter, total nitrogen, total phosphorus, total potassium and available phosphorus content. After two years of rapeseed-rice-bean rotation, the soil alkali-hydrolyzable nitrogen and available potassium content significantly increased, and available phosphorus content increased, but the difference was not significant. After two years of rapeseed-rice-bean rotation, the total content of soil iron, manganese, zinc, copper, and cadmium showed no significant difference, but the available content significantly increased. After two years of rapeseed-rice-bean rotation, the cadmium content in the above-ground straw and brown rice of early rice significantly increased. Under the conditions of this experiment, rapeseed-rice-bean rotation can effectively improve the level of soil available nutrients, but it also significantly reduces soil pH value content, and poses a risk of heavy metal cadmium pollution in early rice.

Key words: rapeseed-rice-bean rotation, soil, physicochemical properties, available nutrients, trace elements
