土壤添加物、土壤微生物和番茄苗期生长相互关系的研究

Study on the interaction among soil additive,soil microorganism and tomato seedling stage

根据植物和微生物生长的特性,分阶段在土壤中加入苜蓿汁、木醋液、葱汁、草木灰4种和有机肥配制的有机添加物,设有机肥处理为对照。研究结果表明,向土壤加入添加物后,土壤微生物的数量明显增加,同时,番茄的株高和株重也有明显变化,处理B在各处理中土壤微生物数量变化最为明显,与对照相比在15d、30d、45d和60d时土壤细菌数量分别增加65.88%、96.14%、80.90%和82.0%;土壤放线菌数量分别增加16.01%、54.01%、49.0%和49.8%,相应地,处理B在番茄苗期最后试验测定时平均株高和平均株重变化也较为明显,比对照分别增加35.22%和34.97%。对各处理结果进行相关性分析发现,对于处理B,不同时间测定中,土壤中细菌数量和放线菌数量与番茄株高和株重均存在显著性正相关关系。

Based on the characteristics of growth of plant organism, add organic additive made of the juice of alfalfas, wooden vinegar liquid, spring onions and juice, 4 kinds of plant ash and organic manure into the soil according to the growth stage, setting organic manure treatment as control. The result of this study shows: after treatment with this organic additive, the quantity of the soil microorganism increases markedly, meanwhile, the height &weight of tomato also have obvious changes, of which the changes of treatment group B is most obvious. Compared with control, the bacterium's quantity in the soil increases by 65.88%, 96.14%, 80.90% and 82.0% in 15d, 30d, 45d and 60d respectively; The quantity of soil antinomies increases by 16.01%, 54.01 %, 49.0%, and 49.8% respectively in the same time points. Accordingly, the average of height&weight of treatment group B increases by 35.22% and 34.97% respectively during the last period of seedling stage of the tomato. ANOVA analysis shows strong positive correlation between bacterium&actinomyces quantity and the height&weight of tomato seedling in various times of measurement.
