为考察普通有机肥、灭菌生物有机肥、加菌生物有机肥对作物生长及设施土壤理化性状的影响,以番茄为试验对象,开展了盆栽试验。结果表明:与不施肥处理(CK)相比,施用有机肥处理(T1~T3)均提高了番茄的产量和含糖量,T3处理的番茄产量较T2处理的提高了22.60%,且差异显著;与CK处理相比,T2、T3处理均改变了番茄根际土壤微生物数量,其中T3处理的番茄根际土壤细菌数量显著提高,真菌和放线菌数量显著降低;与CK处理相比,T1~T3处理均降低了盆栽土壤的容重,降低幅度为5.5%~9.5%;T1~T3处理均提高了土壤中碱解氮、有效磷、速效钾的含量,T3处理的土壤中碱解氮、有效磷、速效钾含量较T1处理的分别提高了10.9%、26.0%、15.1%。
In order to investigate the effect of ordinary organic fertilizer, sterilized bio-organic fertilizer, and microbial bio-organic fertilizer on crop growth and physical and chemical properties of facility soil, a pot experiment is conducted on tomato. The results show that compared with the non-fertilization treatment (CK), the application of organic fertilizer treatment (T1-T3) increase the yield and sugar content of tomatoes. The yield of tomatoes treated with T3 is 22.60% higher than that treated with T2, and the difference is significant. Compared with CK, T2 and T3 treatments both change the number of microorganisms in tomato rhizosphere soil. Among T2 and T3, T3 treatment significantly increased the number of bacteria in tomato rhizosphere soil, while fungi and actinomycetes significantly decreased. Compared with CK, T1 to T3 treatments reduce the bulk density of potted soil by 5.5% to 9.5%. The T1 to T3 treatments all increased the content of alkali hydrolyzed nitrogen, available phosphorus, and available potassium in the soil. The content of alkali hydrolyzed nitrogen, available phosphorus, and available potassium in the T3 treated soil increased by 10.9%, 26.0% and 15.1%, respectively, compared to the T1 treated soil.
