【摘要】:【目的】紫莖澤蘭(Ageratina adenophora)內(nèi)含對微生物、植物和動物有毒的化學物質(zhì),列為我國危害最嚴重的外侵植物,評價腐熟紫莖澤蘭對土壤微生物和作物的毒性,有益于無害化處理生產(chǎn)有機肥!痉椒ā坷梦⑸锞鷦└熳锨o澤蘭,田間設置不施肥(CK)、單施化肥(CF)、單施紫莖澤蘭有機肥(OF)、化肥配施紫莖澤蘭有機肥(50%化肥+50%紫莖澤蘭有機肥,CF+OF)等4種施肥處理,研究了紫莖澤蘭有機肥對土壤細菌、養(yǎng)分和辣椒產(chǎn)量品質(zhì)等的影響!窘Y果】在施用OF的土壤中,微生物碳氮高于CF、OF和CF+OF提高細菌群落的多樣性指數(shù),CF增加優(yōu)勢度指數(shù)。在4種施肥處理的土壤中,酸桿菌門和變形菌門均為優(yōu)勢門類,豐富度合計超過50%;在20種優(yōu)勢菌株中,有7株細菌普遍存在,6 8株細菌單獨存在于不同處理土壤中。此外,在辣椒初果期,CF土壤中的有效養(yǎng)分含量較高;但至末果期,CF+OF處理的有效磷鉀顯著高于CF,堿解氮CF+OF與CF相似。施用CF+OF使辣椒吸收了較多的氮、磷、鉀,辣椒產(chǎn)量比CF增加14.42%,并使果實游離氨基酸和維生素C含量提高,硝酸鹽含量降低!窘Y論】紫莖澤蘭有機肥兼具供肥改土作用,能提高土壤微生物生物量,豐富土壤細菌種群,增加辣椒產(chǎn)量,改善果實品質(zhì)。
[Abstract]:[objective] Ageratina adenophora (Ageratina adenophora), which contains toxic chemicals to microorganisms, plants and animals, is listed as the most serious invasive plant in China, and to evaluate the toxicity of Ageratina adenophora to soil microorganisms and crops. It is beneficial to the production of organic fertilizer by innocuous treatment. Four kinds of fertilization treatments were set up in the field, such as no fertilization, single application of chemical fertilizer CFN, single application of OFN, 50% chemical fertilizer of 50% organic fertilizer, 50% organic fertilizer of Eupatorium purpurea and 50% organic fertilizer of CF-OF. the effect of organic fertilizer on soil bacteria was studied. Effects of nutrients and yield and quality of Pepper. [results] in soil applying of ofs, microbial carbon and nitrogen increased the diversity index of bacterial community and increased the dominance index of bacterial community than CFOF and CFOF. The acidobacterium phylum and Proteus phylum were dominant in the soil of four fertilization treatments, and the total richness was more than 50. Among the 20 dominant strains, 6 or 8 strains of bacteria were found in the soil under different treatments. In addition, the content of available nutrients was higher in the soil of capsicum at the initial fruiting stage, but the available phosphorus and potassium were significantly higher than that in the CFOF treatment at the end of the fruit stage, and the alkali-hydrolyzed nitrogen CF of CF of the soil was similar to that of CF. The application of CF of can increase the yield of capsicum by 14.42% than CF, increase the content of free amino acid and vitamin C, and decrease the content of nitrate. [conclusion] the organic fertilizer has the function of fertilizer and soil improvement. It can increase soil microbial biomass, enrich soil bacterial population, increase pepper yield and improve fruit quality.
