High activity alginate oligosaccharide synergized with urea can increase rice yield by 9.67%

Published Dec 20, 2022 



In 2016, Zhang Yunhong, Henan Academy of Agricultural Sciences, published the article "The impact of alginate oligosaccharide synergic urea on rice yield and quality". The effects of alginate oligosaccharide synergic urea on rice yield and quality were studied in field experiments. The results showed that at the same level of nitrogen application, the yield of 0.3% alginate oligosaccharide synergic urea treatment increased significantly by 9.67%.


Experimental results

1. Effect of AOS synergistic urea on rice yield

High activity alginate oligosaccharide synergized with urea can increase rice yield by 9.67%

It can be seen from the table that AOS synergistic urea treatment is the highest among the following detection indicators. The effective spike number, grain number and yield of AOS synergistic urea treatment in Suxianshi Township were significantly higher than those of ordinary urea treatment, And in Baiji town with an increase of 5.68%, 5.42% and 9.67% respectively; Ordinary urea treatment increased by 4.43% and 4.64% respectively.

2. Effect of AOS synergetic urea on rice quality

High activity alginate oligosaccharide synergized with urea can increase rice yield by 9.67%

It can be seen from the table that the polished rice rate and the whole polished rice rate of rice treated with AOS synergistic urea increased by 2.60% and 25.25% compared with the control, and increased by 1.82% and 10.83% compared with the ordinary urea treatment. The chalky grain rate and chalkiness degree of rice were significantly lower than those of the control, with a decrease of 7.96% and 16.42%, respectively, and a significant increase of 2.25% in transparency. The above results indicated that AOS synergistic urea could improve the processing quality and appearance quality of rice to a certain extent.


In summary, at the same nitrogen application level, compared with common urea treatment, the number of grains per panicle and yield of rice treated with AOS synergistic urea were significantly increased. The rice milling rate and whole rice rate of AOS synergistic urea treatment were significantly higher than those of no nitrogen fertilizer treatment (control) and common urea treatment. It can not only promote the increase of rice yield, but also improve the quality of rice to a certain extent.
