方案详情:
雅致栓孔菌菌种具有两大功能:
( 1 )公司产品仅用于科研通过灌根可有效防治植物细菌性和真菌性土传病害,同时可使植物叶部的细菌和真菌病害明显减少;
( 2 )对植物具有明显的促生长、增产作用。 多粘类芽孢杆菌对细菌性土传病害 ―― 植物青枯病具有很好的防治效果,在收获后期,对番茄、茄子、辣椒、烟草、马铃薯、罗汉果和生姜青枯病(姜瘟病)的田间防效可达 70 ~ -- %,增产率达 493 %,甚至当对照发病率高达 -- %时防效也是如此。 多粘类 芽孢杆菌 对芋头软腐病、大白菜软腐病、辣椒 根腐病 、花卉根腐病、玉竹根腐病、沙参根腐病、番茄猝倒病、番茄立枯病以及辣椒疫病等土传 病害 也具有较好的防治作用。 此外,多粘类芽孢杆菌对 植物 具有明显的促生长作用,可使田间植株高度比空白对照区增加 10-30cm ;甚至在植物不发青枯病时,也可使植物的产量增加 27.5% ,且增产主要表现为收获前期。

文献名: Structural, morphological and optical properties of Bi NPs obtained by laser ablation and their selective detection of L-cysteine 作者: Ramon Gabriel Teixeira Rosaa, Celso de Araujo Duartea , Wido Herwig Schreinera, Ney Pereira Mattoso Filhoa, Arandi Ginane Bezerra Jr.b, Andersson Barisonc, Fernanda Maria Marins Ocamposc a Departamento de Física, Universidade Federal do Paraná Centro Politécnico, CP 19044, 81531-990 Curitiba (PR), Brazil b Departamento Acadêmico de Física, Universidade Tecnológica Federal do Paraná, 80230-901 Curitiba (PR), Brazil c Departamento de Química, Universidade Federal do Paraná Centro Politécnico, CP 19081, 81531-990 Curitiba (PR), Brazil 摘要:In the present work we show the results of the investigation of the properties of bismuth nanoparticles (NPs) obtained by the laser ablation in water. The samples were characterized by various techniques: UV/vis spectroscopy, dynamic light scattering, transmission electron microscopy, X-ray photoelectron spectroscopy, X-ray diffraction, nuclear magnetic resonance and zeta potential. The NPs were metallic and surface oxidated, exhibiting absorption peak at 257 nm due to the surface plasmon resonance. The interaction between the NPs and various amino acids was studied and revealed a selective sensibility to cysteine on a range of concentration from 80 to 720 μM, which we attribute to a dimerization of cysteine to cystine probably complexed to the nanoparticle surface by electrostatic interactions, leading to the modification of the NP absorption spectrum. 关键词:Bismuth; Nanoparticles; Laser ablation; Cysteine

城市污水中TOC与COD的关系
TOC与COD的测定方法不同。测定COD是采用强氧化剂和加热回流的方法,只能将水中的有机物部分氧化(氧化率较低),并且测定时间较长,即使目前一些快速的

4D-脂质组学高通量工作流程
Lipid profiling from complex lipid extracts can be a challenging and time consuming task. The high complexity of samples and co-elution of isobaric or isomeric compounds complicate the confident annotation of lipids. The presented 4D-Lipidomics workflow simplifies and streamlines the annotation and validation process using mobility-enhanced MS data.
