No-tillage (UT) and tillage (TL) influence melon (Cucumis melo L.) production. However, the mechanism of improving the soil quality under UT in melon production is still unavailable. In this study, we attempted to explore the effects of UT and TL treatments on soil fertility and the microbial abundance and diversity in planting melon under greenhouse condition. Soil properties were determined and the bacterial v4-v5 16S rRNA and the fungal internal transcribed spacer gene were pyrosequenced by extracting greenhouse soil DNA. Results showed that the two treatments had different effects on nutrient uptake in melon plants under facility conditions. Additional nitrogen (N) was absorbed in the leaves and fruit in UT treatment. However, the N content in the UT treatment was kept as similar to that of the TL treatment. The phosphorus (P) contents in melon plant leaves and fruits in the UT treatment were higher than those in the TL treatment. High potassium (K) contents were observed in fruits and melon stem under the UT and TL treatments, respectively. Soil pH, organic matter and the available N influenced the bacterial and fungal distributions. The total N, total P and total K in melon plants were correlated with the bacterial and fungal groups in facility soils. The UT treatment had a substantial effect on the microbial diversity in soils planted with melon. Our study provided insights into the response of soil fertility and microbial structures to UT and TL treatments under greenhouse soils, which may aid in managing greenhouse soil quality.

免耕和耕作制度对温室土壤甜瓜（Cucumis melo L.）产量，养分吸收和微生物群落结构的影响

免耕（UT）和耕作（TL）影响瓜（Cucumis meloL.）生产。但是，在瓜生产中，在UT条件下改善土壤质量的机制仍然不可用。在这项研究中，我们试图探索UT和TL处理对温室条件下种植甜瓜的土壤肥力以及微生物丰度和多样性的影响。确定土壤性质，并通过提取温室土壤DNA对细菌v4-v5 16S rRNA和真菌内部转录的间隔基因进行焦磷酸测序。结果表明，两种处理对设施条件下甜瓜植物养分吸收的影响不同。在UT处理中，叶子和果实中吸收了更多的氮（N）。然而，UT处理中的N含量保持与TL处理中的相似。UT处理的瓜类植物叶片和果实中的磷（P）含量高于TL处理。在UT和TL处理下，分别在水果和甜瓜茎中观察到高钾（K）含量。土壤的pH，有机质和有效氮影响细菌和真菌的分布。瓜类植物中的总氮，总磷和总钾与设施土壤中的细菌和真菌类别相关。UT处理对甜瓜种植土壤中的微生物多样性具有重大影响。我们的研究为温室土壤下土壤肥力和微生物结构对UT和TL处理的响应提供了见解，这可能有助于管理温室土壤质量。在UT和TL处理下，分别在水果和甜瓜茎中观察到高钾（K）含量。土壤的pH，有机质和有效氮影响细菌和真菌的分布。瓜类植物中的总氮，总磷和总钾与设施土壤中的细菌和真菌类别相关。UT处理对甜瓜种植土壤中的微生物多样性具有重大影响。我们的研究为温室土壤下土壤肥力和微生物结构对UT和TL处理的响应提供了见解，这可能有助于管理温室土壤质量。在UT和TL处理下，分别在水果和甜瓜茎中观察到高钾（K）含量。土壤的pH，有机质和有效氮影响细菌和真菌的分布。瓜类植物中的总氮，总磷和总钾与设施土壤中的细菌和真菌类别相关。UT处理对甜瓜种植土壤中的微生物多样性具有重大影响。我们的研究为温室土壤下土壤肥力和微生物结构对UT和TL处理的响应提供了见解，这可能有助于管理温室土壤质量。UT处理对甜瓜种植土壤中的微生物多样性具有重大影响。我们的研究为温室土壤下土壤肥力和微生物结构对UT和TL处理的响应提供了见解，这可能有助于管理温室土壤质量。UT处理对甜瓜种植土壤中的微生物多样性具有重大影响。我们的研究为温室土壤下土壤肥力和微生物结构对UT和TL处理的响应提供了见解，这可能有助于管理温室土壤质量。
