maximum at 5 g/L among different straw concentrations. Nutrient accumulation of rice seedlings showed a similar
trend with dry weight. The difference between nitrogen accumulation was the most significant with distilled water as
additive liquid. Only on the 12th day after sowing, the nitrogen and potassium accumulation of rice seedlings at 5 g/
L straw concentration showed significant differences in nutrient solution. Compared with distilled water, N, P, K ac⁃
cumulation of rice seedlings treated with nutrient solution increased by 2.0-3.0 times, 1.0-2.0 times and 1.4-1.7
times. The accumulation of nitrogen and potassium in rice seedlings was the highest at 5 g/L straw concentration,
with no difference in phosphorus. Compared with nutrient solution, the difference in sensitivity index between rape⁃
seed and wheat straw residue leachate was greater than those with distilled water as additive liquid. In conclusion,
both rapeseed and wheat straw residue leachates could promote rice growth. Comparing with wheat straw, rapeseed
straw residue leachate promoted rice growth better.
at Jingzhou, but reduced protein at Jingzhou and Lu′an. Comprehensive score showed extremely differences among
the environments and cultivation conditions. Order of the investigated traits were followed by their comprehensive
scores from high to low: aboveground dry biomass, effective siliques per unit area, branches, 1000-seeds weight, ef⁃
fective length of main raceme, seeds per silique, and oil content.
