| 摘 要： | 采用盆栽种植实验及淋溶试验方法,研究了纳米碳及其与沸石、保水剂等材料复合对油菜生长和土壤氮素淋溶情况的影响.结果表明,在各处理中,纳米碳与沸石和保水剂复合材料处理(N4)对油菜的株高和干重影响最明显,较空白对照组(CK)分别增加21.12%和16.51%;在土壤淋溶试验中,各处理的土壤总氮淋出量较CK减少25.00%~39.21%,其中,累积淋溶中NH+4-N量占总氮量的4.44%~6.73%,各处理间无显著差异,NO-3-N量占总氮量的49.33%~60.05%,但各处理间差异显著;纳米碳和沸石复合处理能有效延缓NO-3-N峰值出现时间,减少NO-3-N流失.因此,N4处理在促进作物生长和氮素保持增效利用方面效果最佳.

| Abstract: | Nano-carbon was composited into different host materials, such as zeolite and water-retaining agents, and a pot experiment and a soil leaching test were conducted to investigate their effects on crop growth and soil nitrogen holding. Results showed that for all treatments, the nano-carbon/zeolite/water-retaining agent composite (N4) could promote the growth of rape the most significantly. The biomass of rape increased by 21.12% in length and 16.51% in dry weight as compared with those in the control. The loss of total nitrogen in all treatments decreased by 25.00%~39.21%, within which NH4+-N and NO3--N contents accounted for 4.44%~6.73% and 49.33%~60.05% of total N. NH4+-N displayed no significant difference among different treatments while NO3--N as one main loss form of N showed significant differences. In addition, the treatment by nano-carbon/zeolite composite effectively delayed the peak of NO3--N and further decreased nitrate nitrogen loss. In conclusion, N4 provided a promising option for crops growth and nitrogen retention. |
