摘要:
利用温室盆栽类芦试验,选取21个土壤物理、化学、微生物学和酶活性指标,采用因子分析等方法,对短期内不同肥料及“蚯蚓-有机物料”协同对被高速公路建设损毁的赤红壤的培肥效应进行综合评价。结果表明:养分释放控制因子、养分供应容量因子和养分供应强度因子是影响土壤综合质量的3个主因子,反映了21个土壤指标所提供的9004%信息量。同等施肥水平,施蚓粪、牛粪比施化肥能显著改善土壤养分释放控制因子,提高土壤养分供应容量,提升土壤综合质量,促进类芦生长,增加类芦生物量;单施化肥仅能显著提高土壤养分供应强度,但由于肥效释放过快抑制了类芦生长,类芦生物量甚至低于对照(P<005);用因子分析法得到不同处理土壤综合质量的排序为50% 牛粪>50% 蚓粪>50% “牛粪+蚯蚓”>25% 蚓粪>25% 牛粪>25% “牛粪+蚯蚓”>50% 化肥>蚯蚓>25% 化肥>对照,与系统聚类分析结果和类芦生物量的排序基本吻合。短期内,对于被高速公路建设损毁的土壤,施有机肥是最优的培肥改良方式。利用因子分析对不同土壤培肥改良方式下土壤综合质量进行评价是可行的。
Abstract:
A pot experiment on Neyraudia reynaudian was carried out to evaluate the effects of different fertilizers (chemical fertilizer, vermicompost, and cattle manure) and earthworm inoculation on the feritility of lateritic soil degraded by highway construction. Factor analysis was applied on 21 selected soil physicochemical and microbiological indices to evaluate the comprehensive the short-term fertilization effect. The results showed that the comprehensive soil quality was controlled by three principal factors, i.e. the controlling of nutrient release, the capacity of nutrient supply, and the intensity of nutrient supply. The cumulative contribution of the three factors was up to 90.04%. Chemical fertilizer significantly increased the intensity of nutrient supply in soil, however, the rapid release of nutrients inhibited the growth of N. reynaudian. Compared with chemical fertilizer treatment, the application of vermicompost or cattle manure at the same level not only improved the controlling factor of nutrient release and the capacity of nutrient supply in soil, but also promoted the growth of N. reynaudian, there by increasing the biomass. The effects on the comprehensive soil quality followed the order of 5.0% cattle manure>5.0% vermicompost>5.0% cattle manure +earthworm> 2.5% vermicompost>25% cattle manure>25% cattle manure +earthworm>50% chemical fertilizer> earthworm>2.5% chemical fertilizer>control, in agreement with the results of hierarchical clustering analysis and the biomass ranking of N. reynaudian. To conclude, for the soil degraded by highway construction, the application of organic fertilizer was the optimal approach for the improvement of soil fertility, and factor analysis was feasible for the evaluation of the effect of fertilization modes on the comprehensive soil quality.
