Abstract:

To determine the effects of partial substitution of different new fertilizers for chemical fertilizer on rice yield and its components under the condition of chemical fertilizer reduction. In 2019, a multipoint field experiment was conducted in Longzhou, Xiangzhou, and Cenxi in Guangxi. Four treatments of conventional fertilization (P1), 10% reduction in conventional fertilization+partial substitution of seaweed fertilizers and microbial inoculant (P2), 20% reduction in conventional fertilization+partial substitution of seaweed fertilizers and microbial inoculant (P3), 30% reduction in conventional fertilization+partial substitution of seaweed fertilizers and microbial inoculant (P4) were set. Dry matter accumulation amount, yield, and its components of rice were measured at maturity stage. The results showed that the average dry matter accumulation amount of three experiment sites, P2 treatment was 6.06% higher than that of P1 treatment, and P3 and P4 treatments were 3.44% and 3.75% lower than that of P1 treatment, respectively. The average yield of three experiment sites, P2 treatment increased by 0.45% compared with P1 treatment, and the average yield of P3 and P4 treatments decreased by 5.40% and 4.08% compared with P1 treatment. It was found that seaweed fertilizer and microbial inoculant could replace 10%-30% chemical fertilizer, the proportion of substitution was related to the soil fertility, and the replacement ratio in different places was slightly different, the suitable replacement ratio of Xiangzhou was 10%, and that of Longzhou and Cenxi were 30%.

Key words: Seaweed fertilizer, Microbial inoculant, Chemical fertilizer reduction, Dry matter accumulation amount, Rice yield
