摘要:

为考察海泡石与生物炭复配对作物养分吸收的影响,以小麦为试验对象,开展了盆栽试验。试验共设5个处理,以复合肥(26-10-12)为对照(CK)处理,测定了不同处理的小麦干物质累积量及植株氮、磷、钾含量。结果表明:肥料中添加海泡石和生物炭对小麦氮、磷吸收具有显著的促进作用,以添加质量分数均为0.5%的海泡石和生物炭的处理效果最好,小麦植株氮含量和氮累积量、磷含量和磷累积量分别比CK处理的提高32%和16%、13%和6%;肥料中添加海泡石和生物炭对小麦钾的吸收无明显的促进作用;海泡石与生物炭复配对作物养分吸收利用的效果优于施用单一材料的,且效果随两者添加量的增加而递增。

Abstract:

To investigate the effect of the combination of sepiolite and biochar on crop nutrient absorption, a pot experiment is conducted on wheat as the experimental object. Five treatments are set up in the experiment, with compound fertilizer (26-10-12) as the control (CK) treatment, to determine the dry matter accumulation and plant nitrogen, phosphorus, and potassium content of wheat under different treatments. The results show that the addition of sepiolite and biochar to fertilizer has a significant promoting effect on nitrogen and phosphorus absorption in wheat. The best treatment effect is when sepiolite and biochar with a mass fraction of 0.5% are added. The nitrogen content and nitrogen accumulation, phosphorus content and phosphorus accumulation of wheat plants are increased by 32% and 16%, 13% and 6%, respectively, compared to the CK treatment. Adding sepiolite and biochar to fertilizer has no significant promoting effect on the absorption of potassium by wheat. The combination of sepiolite and biochar has a better effect on crop nutrient absorption and utilization than the application of a single material, and the effect increases with the increase of the amount of both added.
