大豆是世界上最重要的油料作物,为研究生物炭与丛枝菌根真菌联合施用对大豆幼苗生长的影响,设计室内盆栽试验,种植大豆幼苗,试验设计接种或不接种根内根孢囊霉(Rhi.ophagus i.traradi.es,Ri.并施加0%、2%、5%(w/w)的生物炭,共6个处理。结果表明,接种Ri.施加生物炭,可显著提高大豆幼苗的菌根侵染率、株高、茎粗和生物量,并显著改善了大豆幼苗的光合气体交换活性和叶绿素荧光特性,促进了大豆幼苗的生长发育,其中以接种Ri.施加2%生物炭组合处理促进效应最大,菌根侵染率最高达到76.67%,大豆幼苗的株高、茎粗和总生物量与CK相比分别提高了86.10%、35.69%和80.00%。联合施加Ri.2%生物炭的大豆幼苗的光合气体交换参数及叶绿素荧光参数显著优于CK组(Pi.2%生物炭联合施用能有效增强大豆幼苗的光合能力。因此,Ri.2%生物炭配施具有更好的菌根效应,能有效促进大豆幼苗的生长,这对大豆幼苗的生长及可持续农业发展具有重要意义。

本文报道由于碘离子对不稳定的Ni.Ⅱ)-S(芳基硫醇盐)键的亲核作用,使得Fe(CO)4i.和Ni.SR)2(dppe(SR=芳基硫醇盐)之间的反应生成Ni.2(dppe)。含碘和二芳基硫醇盐离子桥联的Ni.Ni.核配合物[(dppe)Ni.μ-i.(μ-pdt)Ni.dppe)]i.[(dppe)Ni.μ-i.(μ-edt)Ni.dppe)]i.方便地由[Ni.2(dppe)]和[Ni.pdt)(dppe)]或[Ni.edt)(dppe)]在二氯甲烷的溶液中的反应制得;该类反应可认为是由于硫醇盐离子基团中S-供体上的孤对电子对Ni.i.的进攻所致。另一方面,我们观察到[FeCp(CO)2i.和[Ni.pdt)(dppe)]或[Ni.edt)(dppe)]在二氯甲烷中的反应极其缓慢;但当向上述反应体系中加入NH4PF6进行复分解置换后,源于碘离子和Ni.Ⅱ)-S键的作用同样可得到含碘与二芳基硫醇盐离子桥联的Ni.Ni.核配合物[(dppe)Ni.μ-i.(μ-pdt)Ni.dppe)]PF6和[(dppe)Ni.μ-i.(μ-edt)Ni.dppe)]PF6。实验结果说明在本文所讨认的镍(Ⅱ)-硫醇盐离子-膦配合物中,Ni.Ⅱ)-S键的反应活性随桥联的第二金属离子和不同的碘离子基元而改变。

哈尔滨文化中心坐落在松花江北岸的河滨湿地之中,整个项目占地面积1.8km2,建筑面积79 000m2,是这座北国之都著名的自然栖息地——太阳岛北面正在拓展的一部分。2010年2月,MAD通过竞赛赢得了该文化中心项目的设计权。整个建筑群预计将在2014年建成,并在同年7月迎来这座城市著名的音乐盛事——哈尔滨之夏音乐会。

The fi.st search for the doubly heavy Ωbc0baryon and a search for the Ξbc0baryon are performed usi.g pp colli.i.n data collected vi. the LHCb experi.ent from 2016 to 2018 at a centre-of-mass energy of 13 TeV,correspondi.g to an i.tegrated lumi.osi.y of 5.2 *** baryons are reconstructed vi. thei. decays to ∧c+π-andΞc+π-.No si.ni.i.ant excess i. found for i.vari.nt masses between 6700 and 7300 MeV/c2,i. a rapi.i.y range from2.0 to 4.5 and a transverse momentum range from 2 to 20 MeV/*** li.i.s are set on the rati. of the Ωbc0andΞbc0producti.n cross-secti.n ti.es the branchi.g fracti.n to ∧c+π-（Ξc+π-） relati.e to that of the ∧b0（Ξb0） baryon,for di.ferent li.eti.e hypotheses,at 95% confi.ence *** upper li.i.s range from 0.5×10-4to 2.5×10-4for theΩbc0→∧c+π-(Ξbc0→∧c+π-) decay,and from 1.4×10-3to 6.9×10-3for the Ωbc0→Ξc+π-(Ξbc0→Ξc+π-) decay,dependi.g on the consi.ered mass and li.eti.e of the Ωbc0(Ξbc0) baryon.
