【摘要】：為研究短期內(nèi)不同施肥處理對高速公路工程建設(shè)損毀土地的土壤肥力修復(fù)作用,以類蘆為研究對象進行溫室盆栽試驗。結(jié)果表明:蚓糞和牛糞處理較化肥和對照處理土壤容重顯著降低,土壤pH值、土壤孔隙度、田間持水量、有機質(zhì)和全氮含量顯著增大(P0.001);施蚓糞和牛糞處理,類蘆干質(zhì)量、株高、分蘗數(shù)、根系總根長、根表面積、根體積和根均直徑以及植株氮、磷、鉀養(yǎng)分累積量都顯著高于施化肥和對照處理(P0.05);單施化肥抑制了類蘆生長,類蘆生長特征和植株氮、磷、鉀養(yǎng)分累積量都較對照差;施牛糞和施經(jīng)蚯蚓處理牛糞產(chǎn)生的蚓糞對土壤理化綜合質(zhì)量的影響差異不大,但蚓糞比牛糞能有效促進類蘆植株分蘗和根系發(fā)育。短期內(nèi),施蚓糞和牛糞比施化肥能顯著改善高速公路工程建設(shè)損毀土地的土壤物理性狀,提升土壤理化綜合質(zhì)量并促進作物生長,施有機肥,特別是施蚓糞是快速修復(fù)高速公路工程建設(shè)損毀土地的土壤肥力的有效方式。
[Abstract]:In order to study the effect of different fertilization treatments on soil fertility restoration of damaged land in highway construction in a short period of time, greenhouse pot experiment was carried out in this paper.The results showed that the soil bulk density of earthworm manure and cattle manure treatment was significantly lower than that of chemical fertilizer and control treatment, the soil pH value, soil porosity, field water capacity, organic matter and total nitrogen content were significantly increased (P 0.001), and the dry weight and plant height of vermiconium and cattle manure treatments were significantly increased.Tillering number, root total root length, root surface area, root volume and root average diameter, plant nitrogen, phosphorus and potassium accumulation were significantly higher than those of chemical fertilizer and control treatments P0.05.The growth characteristics and plant nitrogen and phosphorus were inhibited by chemical fertilizer alone.The accumulation of potassium nutrients was worse than that of the control, and the effects of cattle manure application and earthworm treatment on soil physical and chemical quality were not significant, but earthworm manure could effectively promote tiller and root system development.In the short term, the application of fertiliser with earthworm manure and cow dung can significantly improve the soil physical properties of damaged land in highway construction, improve the comprehensive physical and chemical quality of soil, promote crop growth, and apply organic fertilizer.Especially earthworm manure is an effective way to quickly restore soil fertility of damaged land in expressway construction.
