Effects of fermentation broth of five strains from bacterial manure on the growth of cucumber and tomato seedlings were studied.The result indicated that all the strains had significant effect on the growth of seedlings.The plant height and stem diameter of cucumber seedlings which were treated with fermentation broth could reach 10.95cm and 0.41cm respectively,which were respectively improved 25.7% and 36.1% compared with the control.The plant height and stem diameter of tomato seedlings which treated with fermentation broth could reach 19.9cm and 0.325cm respectively,which were respectively improved 114% and 30% compared with the control.The result showed that the growth of vegetable seedlings treated with mixed fermentation broth was better than single fermentation broth.

The optimal mediums and subculture time of two tomatoes species(yinghong,J07)for tissue culture were stndied in this article.The result indicated that the explants of yinghong leaf blade were induced to buds directly stronger in modified MS medium adding 1.0mg/L 6-BA and 0.1mg/L IAA than other mediums and browning was lighter taking 12d as subculture time;the optimal medium for explants differentiation of J07 leaf blade was modified MS medium adding 1.0mg/L 6-BA and 0.2mg/L IAA and optimal subculture time was 20d.

The contents of amino acids and crude polysaccharides in Pleurotus ferulae Lanzi fruitbody were determined.The result showed that the total amino acid contents of Pleurotus ferulae Lanzi in pileus and stipe were respectively 13.67%,7.43%.E/T made up 36.87%,37.42%,respectively.F/T were 31.60%,29.48%,respectively and S/T were 20.19%,21.40%,respectively.The contents of amino acids were abundant and proportioned in reason.The contents of crude polysaccharides in pileus and stipe were 45.5mg/g,46mg/g,respectively.

珊瑚菜,又名北沙参,因山东省莱阳市高格庄胡城村所产品质最好,故又名莱胡参.药用部分为伞形科植物珊瑚菜(Glehnia littoralia F.Schmidt ex Miq.)的干燥根,味甘、微苦、性凉,具有养阴清肺、祛痰止咳之功能,主要用于治疗肺热干咳、虚痨久咳、热病伤津、咽干口渴等症.珊瑚菜已成为人们日常生活常用的保健食品之一,在日本、美国及东南亚地区备受青睐,是一种创汇农产品,亩收益可达4 000～5 000元.通过多年的研究,我们整理出了一整套珊瑚菜无公害高产高效栽培技术,现介绍如下.

<正>1产地环境条件芦笋耐寒、耐旱、喜光,选择无污染、排涝方便,土层深厚疏松、通气性好的壤土,微酸性到微碱性为宜。2整地播种2．1施肥整地芦笋是多年生植物,选择高产、优质、抗病的优良

1999～2002年,我们针对出口创汇蔬菜的种类及各自栽培特点,结合当地的气候条件进行了高产、高效间作试验示范及配套栽培技术研究,筛选出三种最佳模式,平均每亩(1亩=1/15公顷)收益4000余元.

芋头属南星科,芋属,它即可作蔬菜,又可主食,具有较高的药用价值.近几年来,芋头的出口量逐年增加,远销日本、新加坡、马来西亚及欧美国家.由于传统的栽培技术过于落后,难以实现高产优质高效.对此,我们进行了3年芋头高效栽培技术的研究,平均每667m2产量3500～4000kg,其中0.1hm2平均667m2产量5385.5kg,经专家验收,创北方地区最高纪录,667m2收益4000元以上.其主要栽培技术要点如下:

1材料和方法 1.1参试品种杏鲍菇品种分别为福建1号、2号,河南3号、7号,北京4号,日本5号,台湾6号,山东8号.试验品种采用随机排列.

利用电子生物技术磁化作物,以改善作物的新陈代谢功能,使其稳健生长,已在多种作物上得到应用.本试验着重探讨经高频电子磁化处理后,对花生种子生物学性状、荚果质量及产量的影响.

The activity of cellulose, laccase, acid protease and polyphenol oxidase on seven strains of Agaricus blazei Murrill was studied. The result showed that the cellulose and laccase coming from the strain Ab6 were higher than the others. Protase's activity is lower than the strain Ab7 and Polyphenol oxidase activity is lower than Abl?Ab2?Ab3 ?Ab4?Ab5.The analysis indicats the strain Ab6 is the best one in the seven.

弧丽钩土蜂是蛴螬的主要寄生天敌之一.早在30年代曾被引到美国防治日本丽金龟取得成功.1995年～2001年,作者对其生物学特性及防治花生蛴螬的运用进行了系统研究,基本摸清了其生活史与习性,并采取插种红麻等蜜源植物,诱集蜂源及采茧助迁,正确运用化防技术建立土蜂安全环境等措施,有效控制了大黑金龟幼虫对花生的危害,取得了显著的社会经济效益和生态效益.

The biology bacteria manure that comes from American contains many strains. It is proved through the experiment that there are three main strains in it: azotobacteria; potassium bacteria; phosphorus bacteria, proportion is 32∶3∶1
