增施腐殖酸及减施化肥对盐碱地粳稻品质的影响
Influence of Increasing Humic Acid and Reducing Chemical Fertilizer on Rice Quality in Saline-alkali Soil
摘要
Abstract
Based on the problem of poor soil quality in saline-alkali soil and low rice quality, this paper studied the effect of increasing humic acid and reducing chemical fertilizer on rice quality. The results showed that increasing humic acid could significantly increase the brown rice rate and polished rice rate, reduce amylose content of rice, and had not significant effect on head rice rate and protein content. The A2 ( 15. 84 g/pot) level of humic acid could significantly improve the taste score of Kenjing 7, and obviously improve the taste quality. The decremental chemical fertilization had markedly improved the taste quality of Kenjing 7, B4 ( decrease 30％) fertilization level had the highest taste score, and had not significant effect on processing quality and nutritional quality; but increased the chalky grain rate and chalkiness, leading to reduce the appearance quality of rice. The combination of humic acid ( 15.84 g/pot) and reducing chemical fertilization ( decrease 30％) significantly improved the taste quality of Kenjing7, but decreased the appearance quality of rice.关键词
