摘要
利用解淀粉芽孢杆菌和粉状毕赤酵母菌接种到褐煤腐植酸中,经好气性发酵生产出生物菌肥,应用于保护地次生盐渍化土壤改良。结果表明,保护地土壤理化性状显著改善,土壤微生物数量明显增多,生物量碳、土壤的呼吸作用和酶活性也有一定增加;土壤中南方根结线虫数量明显减少,有益的小杆线虫数量增多;黄瓜666.7 m2产量9918.4 kg,比CK增产22.61%;黄瓜根系中根结比率降低;黄瓜长势良好,未出现盐渍化危害症状。
The bacteria fertilizer produced by aerobic fermentation with Bacillus amyloliquefaciens and Pichia farinosa that inoculated in lignite humic acid were used to improve secondary salination soil in greenhouse. The result showed that the quantity of soil microorganisms, Caenorhabditis elegans, microbial biomass carbon, soil respiration and soil enzyme activities were increased. On the contrary, the quantity of Moidogyne incognita decreased significantly, indicating that the bacteria fertilizer could improve the physicochemical properties of soil significantly. Comparing with CK, The yield of cucumber increased 22.61%, while root tubercle rate decreased respectively. Moreover, there is no symptom of salination found after using the bacteria fertilizers.
