【摘要】：為紫莖澤蘭是我國危害最嚴(yán)重的外來入侵植物,具有生物毒性,無害化處理與資源化利用可經(jīng)濟(jì)、有效地防除紫莖澤蘭。試驗(yàn)檢測了紫莖澤蘭生物堆肥的質(zhì)量,并將紫莖澤蘭生物堆肥(M)、化肥(CF)和生物堆肥+化肥(CFM)分別施入土壤,利用培養(yǎng)試驗(yàn)比較了它們對土壤有機(jī)質(zhì)、養(yǎng)分和微生物的影響,為客觀評價(jià)紫莖澤蘭生物堆肥質(zhì)量、微生物毒性和肥效提供有益信息。結(jié)果表明,紫莖澤蘭生物堆肥質(zhì)量符合NY525-2011國家標(biāo)準(zhǔn)(水分除外),且優(yōu)于自然堆肥。在120 d的培養(yǎng)期間,CF處理降低土壤真菌和放線菌數(shù)量,對細(xì)菌數(shù)量無顯著影響;CFM和M處理可提高土壤有機(jī)質(zhì)和微生物量碳、氮,增加土壤細(xì)菌、真菌和放線菌數(shù)量。在添加化肥的土壤中,培養(yǎng)前期的堿解氮、脲酶和蔗糖酶活性高于CK(不施肥),后期與CK無顯著差異。在CFM和M處理的土壤中,堿解氮變化平緩,但持續(xù)高于CK,蔗糖酶、脲酶、酸性磷酸酶和過氧化氫酶活性顯著高于CF和CK。因此,紫莖澤蘭生物堆肥對土壤有機(jī)質(zhì)、氮、微生物生物量及土壤酶活性的影響類似于普通有機(jī)肥。
[Abstract]:It is the most serious invasive alien plant in China. It has biological toxicity, harmless treatment and resource utilization can be economical, and effectively prevent and control Eupatorium purpurea.The quality of biological compost of Eupatorium purpurea was tested, and the effects of organic matter, nutrient and microorganism on soil organic matter, nutrient and microorganism were compared by applying CFM, CFM and CFM, respectively.It provides useful information for the objective evaluation of compost quality, microbial toxicity and fertilizer efficiency of Eupatorium purpurea.The results showed that the compost quality of Eupatorium purpurea was in accordance with the NY525-2011 national standard (except water content) and was superior to that of natural compost.During 120 days of culture, CF treatment decreased the number of soil fungi and actinomycetes, but had no significant effect on the number of bacteria. CFM and M treatments could increase soil organic matter and microbial biomass carbon, nitrogen, and increase the number of soil bacteria, fungi and actinomycetes.The activities of urease and sucrase in the soil with chemical fertilizer addition were higher than those in CK at the early stage of culture (no fertilizer application, but there was no significant difference between the latter stage and CK).In soil treated with CFM and M, the activity of alkaline hydrolyzed nitrogen changed slightly, but continuously higher than that of CK, sucrase, urease, acid phosphatase and catalase, which was significantly higher than that of CF and CK.Therefore, the effects of biological compost on soil organic matter, nitrogen, microbial biomass and soil enzyme activity were similar to those of common organic fertilizer.
