Abstract：The effects of alginate-derived oligosaccharides( ADO) synergistic urea on the yield and quali-ty of rice( Oryza sativa L. ) were studied under field-grown condition,in order to provide references for the industrialization of ADO synergistic urea and its application in agriculture. The results showed that the treatments of ADO synergistic urea increased the grains per panicle as well as yield significantly compared with the common urea with the same content of nitrogen. The milled rice rate,head rice rate and protein contents of ADO synergistic urea treatment were higher than those of the control without urea and common urea treatments,with the increase amplitude of 1. 82%,10. 83% and 7. 59% respectively compared with common urea treatment; the setback value was lower than those of the control without urea and common urea treatments,reduced by 36. 02% obviously compared with common urea treatment. Moreover,trans-parency,gel consistency, alkali spreading value, the maximum viscosity and breakdown values of ADO synergistic urea treatments were higher than those of the control without urea and common urea treat-ments,and chalky rice rate and chalkiness were lower. These differences with the control without urea reached significant level. Taken together,these results indicated that application of ADO synergistic urea could increase yield,and had a certain improving effects on quality.
