摘 要：We conducted a pot experiment to examine the feasibility of applying a reaction-finished solution of hydrochar(HRFS)to enhance rice production in a saline *** this purpose,HRFS was applied(0,10,20,40,60,80 and 100 mL/pot)and rice yield and nitrogen(N)use efficiency(NUE)were *** application significantly(P0.05)increased rice grain yield by 19.6%-30.0%compared to the control treatment(CKU,with N but without HRFS addition).Moreover,HRFS application promoted plant height and straw biomass of *** of rice yield were mainly achieved by increases in the number of panicles and grains per *** with the CKU treatment,the NUE of HRFS amendments significantly(P0.05)increased by 56.3%-71.7%.This indicated that the improvement of NUE was one of the mechanisms to improve rice grain yield with HRFS *** results of regression analysis showed that there was a positive relationship(R^(2)=0.8332)between rice yield and HRFS application rate within an appropriate *** highest rice yield was recorded with the HRFS application of 40 mL/pot,but a further increase in HRFS application rate appeared to reduce rice *** on the results of this pot study,HRFS application can increase rice yield in a saline soil by regulating its yield components and enhancing ***,impact of HRFS on these variables showed a“dose effect.
