丛枝菌根真菌与化肥共施对水稻品质的改善作用

Effect of interaction between inoculation with arbuscular mycorrhizal fungi and fertilization on rice quality

为探讨化肥施加与丛枝菌根真菌(AMF)接种的共同作用对水稻品质的影响,在大田条件下分别对施肥条件下和不施肥条件下的水稻进行AMF接种,并在收获后测定稻米品质.结果表明:不施肥条件下AMF接种降低了稻谷的加工品质和外观品质,对蒸煮、食味及营养品质无显著影响;化肥的施加提高了稻谷的加工品质和蒸煮品质,但降低了稻米的外观品质、食味品质和营养品质;AMF接种和化肥共施改善了稻谷的外观品质、蒸煮食味品质,并保证了稻米中铁和锌的质量分数.AMF接种和施加化肥单独都不能显著改善水稻品质,但二者共同作用能够达到改善水稻品质的目的.

The aim of our study is to estimate the effects of inoculation with arbuscular mycorrhizal fungi and fertilization on rice quality. Rice quality was estimated for inoculated and non-inoculated rice grown in both fertilized and non-fertilized paddy fields. It was found that in non-fertilized paddy fields there was a negative effect of inoculation on rice processing and appearance quality but no significant effect on cooking,tasting and nutrition quality. In addition,fertilization improved rice processing and cooking quality whereas no significant effect was found on appearance,tasting and nutrition quality. Finally,the interaction between inoculation and fertilization improved appearance,cooking and tasting quality and guaranteed the Fe and Zn content of rice. In conclusion,interaction between AMF inoculation and fertilization plays a vital role in improving rice quality.
