摘要

New technology of dry distillation under hypoxia condition was used for made biochar (biomass-derived black carbon).The effects of biochar application on rice were studied by pot experiment. Before rice transplant, soil were treated with three different weight levels of biochar and no biochar as control (CK).The results show that biochar amendments in rice soil could boost height of rice, and also increased the dry matter accumulation of leaf, stem and root at various growth stage. The rice net photosynthetic rates of biochar treatments were higher than control. Transpiration rate of biochar treatment was increased at the tillering stage and filling stage, declined at the jointing stage and heading stage as well. Rice yield per hill of biochar treatments were higher than control for the main reason of the panicles per hill and spikelets per panicle increased. The rice yield of C2 (20g·kg-1 biochar amendment) was the highest which significant difference compared with other treatments. Rice milling and appearance quality of biochar treatments were better than control with brown rice rate, milled rice rate and head rice rate were increased while the chalky grain rate and chalkiness were decreased. Rice protein and fatty acid content of biochar treatments were decreased, but the rice cooking quality was significantly increased.
