摘要:

以丹粳17、丹粳21、中丹4号为试验材料,研究了不同氮肥水平条件下生物菌肥对丹东地区水稻品质的影响。结果表明,不同氮肥水平下,施用生物菌肥能够提高稻米籽粒的长宽比,显著降低垩白粒率和垩白度,增加稻米的胶稠度、粗脂肪含量和直链淀粉含量,提高了稻米的食味值,改善了稻米的食用品质。

Abstract:

The effects of biological fertilizer on the quality of rice was studied under different nitrogen levels in Dandong area using Dangeng 17, Dangeng 21 and Zhongdan 4 as materials. The results showed that biomass fertilizer could improve the length-width ratio, significantly reduce the chalky rice rate and chalkiness degree, increase the gel consistency, crude fat content and amylose content of rice, and improve the taste value and eating quality of rice under different nitrogen levels.

Key words: biomass fertilizer, rice, yield traits, quality
