为探讨在设施栽培条件下,不同比例有机无机肥配施对番茄生长及土壤性状的影响,试验设计了5个施肥处理,测定土壤速效养分、pH值、EC值、紧实度及番茄生物量的变化。结果表明:微生物有机肥具有显著提高土壤有效磷、速效钾含量、降低土壤紧实度,并促进植株生长,达到平衡养分,改善土壤理化性质等效果;化肥减量30%对植株生长无显著影响;通过试验可见,微生物有机肥具有改良土壤环境,促进植株生长等作用。
In order to explore the effects of organic and inorganic fertilizers with different proportions on the growth and soil properties of tomato under the cultivation conditions, five fertilization treatments were designed and tested. The soil available nutrients, pH value, EC value, compaction and tomato biomass The change. The results showed that microbial organic fertilizer could significantly increase soil available phosphorus and available potassium, reduce soil compaction, promote plant growth, achieve balanced nutrition and improve soil physical and chemical properties. No significant effect of microbial fertilizer on plant growth was observed It can be seen from the experiment that the microbial organic fertilizer has the functions of improving soil environment and promoting plant growth.
