摘要
[目的] 推广应用稻鳅共作种养模式. [方法] 开展大棚盆栽试验,观察稻鳅共作和水稻单作2种处理对稻田土壤性质及水稻产量构成的影响. [结果] 相比于水稻单作,稻鳅共作可使土壤的pH趋于中性,减缓土壤有机质的下降,增加碱解氮的含量,提高土壤肥力,促进水稻对于磷、钾元素的吸收,使水稻长势变好.稻鳅共作显著影响水稻生长,水稻分蘖率明显提高,水稻产量涨幅很大. [结论] 稻鳅共作种养模式具有很高的环境效益和经济效益,应用前景广阔.
Abstract
[Objective] To popularize and apply rice-loach culture system.[Method] To observe the effects of rice-loach culture and rice monoculture on soil properties and rice yield components by the greenhouse experiment.[Result] Compared with rice monoculture, the soil pH tended to neutral, the decline of soil organic matter was slowed down, the content of alkali-hydrolyzable nitrogen was increased, the soil fertility was improved, and the absorption of phosphorus and potassium was promoted, rice grew better in the technology of rice-loach culture.Rice-loach culture significantly affected the growth of rice, the tillering rate of rice was significantly improved, and the rice yield increased greatly.[Conclusion] Rice-loach culture technology has high economic and ecological benefits, with broad application prospect.
