玉米秸秆生物炭对盆栽花生生长的影响

Effects of Corn Straw Biochar on the Growth of Potted Peanut

选用玉米秸秆为原料,通过水热法制备生物炭,在腐植酸复合肥施用量一定的条件下,利用花生盆栽试验,验证增施生物炭及其复配产品对花生生长指标及产量的影响。结果表明,单独增施生物炭能显著提高花生叶片叶绿素相对含量,可提高11.1%,且对产量有明显的促进作用,增幅达22.3%,但对花生株高生长无明显效果。

With a certain amount of humic acid compound fertilizer,the effect of biochar and its compound products on growth index and yield of peanut was studied with potted plant test to verify the role of biochar on peanut growth and production by biocarbon made with corn straw by pyrolysis.The results showed that adding biochar could significantly increase the SPAD value of leaf by 11.1%,and promote the yield by 22.3%,while not on plant height.
