为探索葡萄延迟栽培技术,以半地下式日光温室内2年生摩尔多瓦葡萄为试材,系统地研究推迟萌芽＋延迟采收＋挂树贮藏综合措施的延迟栽培效果。结果表明：在河北省阳原地区,摩尔多瓦葡萄可推迟至5月上旬萌芽,8月20日果粒开始着色,10月21日成熟,成熟后可挂树贮藏至元旦。浆果采收期比露地延迟50-120d,上市期为10月下旬至元旦。延迟采收前40d内,果粒体积和果粒重逐渐增大,可溶性固形物含量继续升高,酸含量、硬度降低,果皮变薄,颜色由蓝黑色变为黑色,口感多汁、浓甜和酸味消失;40d后,可溶性固形物含量继续升高,粒重开始下降,可滴定酸含量变化不大。利用春季夜间低温推迟葡萄萌芽期、秋冬季保温延迟采收和落叶后挂树贮藏3项关键技术措施,可使北方日光温室摩尔多瓦葡萄比露地栽培推迟50-120d上市,为11月至元旦市场和冬季观光采摘市场提供优质新鲜葡萄。

Constraints on holographic QCD phase transitions from PTA observations

Science China(Physics,Mechanics & Astronomy) 2025年第1期Mechanics & Astronomy) .卷 71-78页

作者： Song He li li Sai Wang Shao-Jiang Wang Center for Theoretical Physics and College of Physics Jilin University School of Physical Science and Technology Ningbo University Max Planck Institute for Gravitational Physics (Albert Einstein Institute) CAS Key Laboratory of Theoretical Physics Institute of Theoretical Physics Chinese Academy of Sciences School of Fundamental Physics and Mathematical Sciences Hangzhou Institute for Advanced StudyUniversity of Chinese Academy of Sciences (UCAS) School of Physical Sciences University of Chinese Academy of Sciences (UCAS) Theoretical Physics Division Institute of High Energy Physics Chinese Academy of Sciences

The underlying physics of QCD phase transition in the early Universe remains largely unknown due to its strong-coupling nature during the quark-gluon plasma/hadron gas transition, yet a holographic model has been proposed to quantitatively fit the lattice QCD data while with its duration of the first-order phase transition(FoPT) left undetermined. At specific baryon chemical potential, the first-order QCD phase transition agrees with the observational constraint of baryon asymmetry. It, therefore, provides a scenario for phase transition gravitational waves(GWs) within the standard model of particle physics. If these background GWs could contribute dominantly to the recently claimed common-spectrum red noise from pulsar timing array(PTA) observations, the duration of this FoPT can be well constrained, and the associated primordial black holes are still allowed by current observations.
