The appearance and development of protective culture (facilities horticulture) as an agricultural productive method served the royal and the nobility in ancient tine. In west since the sth emperor-Nero time of the Roman Empire, mica sheet and talcum sheet were used to cover the digged pit where the protective culture was carried on.In China the exact record was in B.C.33 Han Dynasty,burning firewood was used to warm the house, in which the vegetable production was conducted.Because of the affection of feudalistic and superstitions ideolgy-it was harmful to eat these vegetables,the production had not been developed for a long time.In Tang Dynasty(A.D700).it was recorded that not spring was used to cultiivate certain melon for the court. As to the history of cucumber production in greenhouses in Beijing (peking) it can be traced back to the middle period of Ming Dynasty(A.D.1600).We firmly believe that the appearance of these things should be earlier than these writing vecord.

保护地栽培(设施园艺)做为一种农业生产方式的出现和发展,在古代都是为宫廷和贵族服务。西欧是从古罗马帝国的第五代皇帝尼禄(Nero)时期(公元54—68年)掘坑后覆盖云母或滑石板片进行保护地栽培。中国确切的记载是在公元前33年汉朝时期,采取燃柴草加温的方法在室内进行蔬菜生产。由于封建迷信思想(认为食之有害)的影响长期以来没有得到发展。到唐朝(公元7世纪)又有利用温泉为宫廷种植瓜类的记载。至于北京温室的历史可以追溯到明朝中叶(公元16世纪)。许多栽培技术究竟从什么时候开始至今无法肯定,但一定比文字记载要早,这是完全可以肯定的。

Damaged roots were separately inoculated with culture suspensions of Azorhizobium caulinodans ORS571, Bradyrhizobium sp.(peanut) 147-3, Rhizobium sp.

Seedling roots of Graminae, cruciferae and cucurtibaceae families were pretreated by penctin-lytic bacteria, during which root hairs were first damaged and cleared away finally. Damaged roots were separately inoculated with culture suspensions of Azorhizobium caulinodans ORS571, Bradyrhizobium sp.(peanut) 147-3, Rhizobium sp. NGR234, Azotobacter vinelandii and Azospirillum brasilense 251-5 strains. Among 8 plant species treated two were nodulated by any of the strains used, i.e. para nodules forme on pakchoi and cucumber. Wheat was only nodulated by strain 147-3.Nodulation frequency on pakchoi reached as high as 95% induced by strain 147-3. Cucumber followes, being 50%. Light microscopy of para-nodule sections showed clearly that nitrogen-fixing organisms were observed in nodule cells, and distributed from outercortex to inner cortex near stele. Using acetylene reduction assay, nodules on pakchoi formed by strain ORS571 showed apparent nitrogenase activity.

Cucumber mosaic virus (CMV) was detected in single aphids Myzus persicae and Aphis gossy pii by dot immunobinding assay (DIBA). The DIBA procedure with the lowest detectable concentrationendpoint of 0.16ng/ml of purified CMV, or 0. 32pg per sample dot of 2μl antigens, satisfied the sensitivityrequired for the detection of CMV in single virus-carrying aphids. The aphid extracting method of dippingthe stylets dissected from aphid heads in the droplets of small volume (2-5μl) of suitable buffer not onlyensured the highly concentrated viruses fully released from the aphid stylets, but decreased the interference of non-virus materials from aphids to minimum as well, and thus overcame the two major difficulties in the detection of plant viruses in vectors. The virus-carrying rates tested by DIBA had good coincidence with the transmission rates by bioassay. Undoubtedly, such breakthroughs in the technique of detecting nonpersistent viruses in aphid vectors are of great epidemiological importance.

本文报道了用点免疫印迹法(DIBA)检测单头桃蚜(Myzus persicae)和棉蚜(Aphis gossypii)所带黄 瓜花叶病毒(CMV)的试验结果,作者摸索出的DIBA法操作程序用于检测提纯的CMV最低下限浓度为0.16ng/ml,即每2μl样品含0.32pg抗原.这样的灵敏度是可以检测出单头蚜虫所带CMV的。这种操作程序是将蚜虫口针截取下来,浸入适当的缓冲液(2—5μl)内。这不仅保证了CMV病毒粒子充分地从蚜虫口针上释放出来.形成较高的浓度,而且极大限度地减少了非病毒物质对检测的干扰,因此就克服了从单头介体昆虫上检测所带植物病毒时常遇到的病毒浓度太低和非病毒抗源干扰两大困难。试验还表明。用这种DIBA法检出的蚜虫带毒率同生物测定试验检出的蚜虫传毒率有很好的一致性。显然,在蚜传非持久性病毒检测技术上的这一突破,对于植物病毒病流行学研究具有重要意义。
