不同镧肥施用量对香稻产量及糙米香气含量的影响

Effects of Different Applications of LaCl_3 on Yield and Aroma Contents of Aromatic Rice

以常规香稻品种桂香占为材料,采用盆栽试验,研究了不同镧肥施用量对香稻产量及糙米香气含量的影响.结果表明,基施LaCl380、100 mg.kg-1处理能够提高香稻的有效穗数和结实率,从而提高其实际产量;LaCl3亦能提高香稻糙米的香气含量,其中以基施LaCl3180 mg.kg-1的糙米香气含量最高,基施LaCl3100 mg.kg-1糙米香气含量次高;协同提高香稻产量和香气含量的最佳LaCl3基肥施用量为100 mg.kg-1.

Effects of different applications of LaC13 as base fertilizer on yield and aroma contents of aromatic rice were studied in pots by using one conventional aromatic rice cultivar, Guixiangzhan. The results showed that applications of 80,100 mg·kg^-1 LaCl3 improved the yield and increased aroma contents of aromatic rice. The application of 180 mg· kg^-1 LaCl3 had the highest aroma content,and the application of 100 mg · kg^-1 LaCl3 had the second high aroma content. The optimum application coordinating high yield and aroma contents of aromatic rice was 100 mg· kg^-1 LaCl3.
