Abstract:In order to study the influence of reduced chemical fertilizer with commercial organic fertilizers and bio-organic fertilizers on the yield and quality of high-quality indica rice, a field experiment was conducted in which six high-quality indica rice varieties and 4 fertilizer treatments were designed, including no fertilization (CK), chemical fertilizer (CF), apply commercial organic fertilizer and chemical fertilizer according to 1︰1 nitrogen content (SF), and apply bio-organic fertilizer and chemical fertilizer according to 1︰1 nitrogen content (WF). The results show that: 1) Fertilization significantly improves the yield of high-quality indica rice. Compared with CF, the combined application of organic fertilizer significantly decreases the yields of all varieties, whereas the rice yield in combined application of bio-organic fertilizer is slightly higher than that of commercial organic fertilizer. 2) Compared with CF, the combined application of organic fertilizer improves rice processing quality and reduces the appearance quality by increasing rice milling rate, chalkiness rate and chalkiness degree, and a few varieties reach the significant level. 3) Compared with CF, the combined application of organic fertilizer increases rice gel consistency, and the combined application of bio-organic fertilizer reaches the maximum. However, the protein contents of most varieties are significantly lower than CF, thereby improving the palatability of rice. 4) Compared with CF, combined application of organic fertilizer increases the peak viscosity and breakdown, decreases setback and pasting temperature, while the RVA profile characteristics of rice is close to the level of no fertilization treatment. In conclusion, the combined application of organic fertilizers can improve the taste quality of rice, especially the combined application of microbial organic fertilizers.
