摘要
对水稻开展施用有机肥自然富硒的技术研究。结果表明:不同有机肥对水稻产量影响表现不一,增产-3.9%~7.6%;对水稻稻谷硒含量影响不一,除"禾立嘉"处理接近富硒稻谷标准外,其他有机肥处理全部达到富硒稻谷标准,但只有应用"顺宝"有机肥的稻谷籽粒硒含量高于常规施肥,施用有机肥能够不同程度地提高土壤硒含量。
Natural selenium-enriched technology of applying organic fertilizers on rice was studied. The result showed that different organic fertilizers had different effect on rice yield, with yield increasing by -3.9%~7.6%. Different organic fertilizers also had different effects on selenium content of rice. Except for Helijia treatment, other organic fertilizer treatments could all meet the standard of selenium-enriched rice. Only Shunbao organic fertilizer had better performances in increasing selenium content than normal fertilizers. Organic fertilizers can increase selenium content of soil in varying degrees.
