摘要:

为明确生物炭不同施入量对大豆生长发育及产量的影响。采用盆栽试验,生物炭施入量设6个处理。于大豆开花期观测大豆株高,茎叶、根系鲜重和干重等地上、地下部分的主要农艺性状,在大豆收获期测量各处理主要产量性状及产量指标。结果表明,施入生物炭对大豆生长前期主要农艺性状和成熟期产量性状及产量有显著影响,其中生物炭最佳土壤施入量为210.0 kg/hm2,产量比对照提高38.48%。生物炭施入量与大豆产量之间的关系符合二次函数模型(R2=0.9368,P=0.0159)。可见,在土壤中施入适量生物炭对大豆的生长发育及产量有明显的促进作用,过量施入则抑制大豆生长并导致产量降低。

Abstract:

In order to understand the effect of biochar application on soybean growth and yield, biochar with six different application amounts were applied in pot experiment. Main agronomic traits including plant height, fresh weight and dry weight (stem, leaf and root) were measured at flowering stage of soybean. Then the main yield characters and yield indexes were measured in the harvest period. The results show that the application of biochar has significant effects on the main agronomic traits in the early growth stage, even influencing yield and its traits in maturity stage of soybean obviously. The optimum application amount of biochar is 210.0 kg/hm2, under which the yield is 38.48% higher than the control. The relationship between the application amount of biochar and soybean yield is accordant with the quadratic function models: (R2=0.9368, P=0.0159). It is clear that moderate application of biochar in soil can promote the growth and yield of soybean, while excessive application can inhibit the growth and lead to the decrease of yield.
