| 摘 要： | 【目的】研究生物炭的施入对玉米生长及植株不同部分磷吸收的的影响。【方法】采用盆栽试验,以玉米为供试作物,通过施用不同量的生物炭,研究不同施肥条件下,生物炭对玉米生长和磷吸收的影响。【结果】在不施氮肥的条件下,生物炭对玉米干物质积累量具有抑制作用,但提高植株磷吸收总量;在施氮条件下,生物炭能明显增加玉米的生物量(P<0.05),显著提高茎秆、叶片、籽粒磷吸收总量(P<0.05),明显降低根部磷吸收总量(P<0.05);随着炭施入量的增加,单株磷吸收量明显增加(P<0.05);生物炭处理能明显提高磷肥利用效率(P<0.05),利用效率变幅为20.73%~24.66%,相对于不施炭增幅达7.99%~30.76%。【结论】生物炭与氮肥、磷肥配施能够促进玉米生长,提升磷肥利用效率。

| Abstract: | 【Objective】 To study the effect of biochar application on the growth of maize and phosphorus absorption of different parts of the plant. 【Methods】 Pot experiment was used to study the effects of biochar on maize growth and phosphorus absorption under different fertilization conditions. 【Results】 Under the condition of no nitrogen application, biochar inhibited the accumulation of dry matter in maize, but increased the total amount of plant phosphorus absorption; under the condition of nitrogen application, biochar could significantly increase the biomass of Maize (P< 0.05), the total amount of stem, leaf and grain phosphorus absorption (P< 0.05), but significantly reduce the total amount of root phosphorus absorption (P< 0.05); with the increase of carbon application, biochar could significantly increase the total amount of plant phosphorus absorption (P< 0.05). In addition, phosphorus absorption per plant increased significantly (P< 0.05); biochar treatment could significantly improve the utilization efficiency of phosphorus fertilizer (P< 0.05) and the utilization efficiency range was 20.73%-24.66%, which was 7.99%-30.76% higher than that without carbon application. 【Conclusion】 The application of biochar combined with nitrogen and phosphorus can promote the growth of maize and improve the utilization efficiency of phosphorus. |
