指出了近年来我国雾霾天气频发,河北省尤其严重,雾霾对农业生产以及对农产品质量的影响也日趋严重.针对雾霾天气对作物产量、质量和病虫害的影响进行了分析,探讨了解雾霾对农产品质量的危害,提出了应加强对治理雾霾的认识.

档案的收集与整理是档案管理的基础性工作,一个档案管理机构的管理水平如何,最主要的是看其库存档案保管质量和库存档案利用价值的高低.提高档案的管理水平,就必须首先做到高水准的收集与整理工作. 1 档案材料的收集 1.1档案管理的重要性.档案工作的特点是“做起来不起眼,整起来很麻烦,用起来离不开,时间长了用起来更重要”.档案工作的性质决定了干这一行的人要具有踏实肯干、无私奉献的精神.

根据河北省农林科学院遗传生理研究所库存农业科技档案的特点,分析了对农业科技档案进行分类的各种方法的优缺点,为更合理地进行农业科技档案管理,提高农业科技档案的利用效率提出了参考意见。

从南非引入24份玉米种质资源进行初步试种,结果表明:南非22号比对照农大108增产44.4％,子粒赖氨酸含量比对照略高；南非9号比对照增产37.5％,但子粒赖氨酸含量比对照低5.6％；南非3号增产11.2％.南非2号与5号的子粒赖氨酸含量分别比对照高10.3％与8.6％,达极显著水平,其他12个品种子粒赖氨酸含量也均超过了对照.通过南、北方4个生长季节的试种、产比与选育,已获得各类优株穗选资源共计300个穗,丰富了当地种质资源.

<正>在长期的农业科研活动和科技资料的积累中,形成了大量对农业生产有指导意义从而产生巨大经济效益的实用科技档案。这些档案资料有很大一部分被存放在档案室中,未发挥出它应有的作用,造成农业科技资源的巨大浪费。由于各种各样的原

The relationship between agricultural science and technology archives and agricultural research is analyzed.The roles of agricultural science and technology describes archives in servicing agricultural research are introduced.

通过对农业科技档案和农业科研的辩证关系的分析,表明农业科研活动是农业科技档案的源泉,农业科技档案的充分利用,对农业科研工作具有促进作用,二者相互依存、互相促进。

The current situation of archives management team in agricultural scientific research units is analyzed,the key problems limiting the archives management team construction are found,and the improvement suggestions are put forward.

The research characteristics of biomass energy,the status of utilization of agricultural resources and the research progress development of biomass energy at home and abroad are describes.The preparation of hydrogen using crops straw via anaerobic fermentation and the research techniques of synthetic oil from biomass by Hebei Plant Transgene Center are introduced.The biomass energy can ease the pressure from energy.The significance of biomass energy research is explained,and the biomass energy research in the future is discussed and prospected.

Apoptosis in protoplasts and leaves from Homokaryon maize B37 treated by HMC toxin were studied.The apoptotic features such as apoptotic bodies,chromatin margination or ring chromatin were found after the treatment stained by Hoechst33258.When treated by the same concentration of HMC toxin,the apoptosis rate of B37-C maize protoplasts were significantly higher than B37-N.In addition,the apoptosis rate was increased when the treatment time and concentration increasing.For the leaves of maize B37-C,the obvious DNA ladder was appeared with treatment concentration:200 μg/mL;treatment time:6 h.For the leaves of maize B37-N,the obvious DNA ladder was appeared with treatment concentration:200 μg/mL;treatment time:9 h which was longer than leaves of maize B37-C.Apoptosis in protoplasts from Homokaryon maize B37 were same to the leaves.B37-C was more sensitive than B37-N.

<正>1过分依赖化学农药忽视病虫综合防治中的其他措施,导致病虫害普遍发生时的被动化学防治,这是当前农业种植业生产中较为突出的问题。2施药方法单一仅仅采用喷雾法,忽视选用一些新型农药的施药方法。

工作着是美丽的,美丽的人生因工作而散发出奕奕光芒.全国三八红旗手、省十大女杰、我院研究员周人纲同志就是这样一位受人尊敬的科技工作者.

农业科研单位的改革势在必行,不改革就没有出路,不改革研究所就不可能蓬勃发展,职工的积极性就不可能充分发挥出来,要改革就必须破旧立新,从人的思想观念上、组织机构的管理上和人才流动上做大的变革.所有这些都需要领导者有魄力、有能力,能够调动广大科研人员的积极性,在紧紧围绕建立公司制为中心的前提下加快改革步伐,建立起产权明晰、权责明确、政企分开、管理科学的现代企业.
