摘要

Effects of two types of biochars from wheat straw (SB) and hard miscellaneous woods (WB), combined with two types of soils on the growth and yield of wheat were evaluated to identify biochar addition to suitable soils on crop yield for accelerating biochar application. Plant growth variables and yields were studied in order to assess the agronomic efficiency of biochar. Our results showed that both biochar additions to an alkaline soil had little or negative effect on plant growth and wheat yield. However, to neutral soil, addition of both biochars could improve plant growth and increase significantly the wheat yield. There were significant differences on effective spikelet, number of seeds, above ground biomass and no significant differences on total spikelet, TKW among different treatments which SB was applied in neutral soil, whereas there were no significant differences on any aforementioned index at application of WB in neutral soil. Further analysis indicated that effect of SB on yield was better than that of WB, and 6% SB and 2% WB were the best for neutral soil respectively.
