Study on the rapid Propagation Technique of Lycoris. Herb and get follow results: In the period found of axenic clone 0.1%HgCl2 is the best disinfector to deal with the Lycoris" bulb ,as to neat part, such as root, leave, and bulbil, is fit to use 0.1%HgCl2 antisepsis 7min. And found the best effect is the bulb scale with base. Root, leaf and bulb scale without base all were not inducement adventitious buds. Different position of bulb had different culture effect. 3-15 of middle part of bulb can be induced most adventitious buds but inner and outer of least it. Incised the bulb with three types (pieces of eight, pieces of six, piece of four), and found the type of pieces of six is best to Lycoris mass production. L.sprengeri is fit MS+BA5mg/l+NAA0.1mg/l and L.squamigera is fit MS+BA5mg/l+NAA0.5mg/l, but the medium fit to culture L.longituba haven"t be found.In the period of Subculture-Found of mass production, the most multiplication of adventitious buds in MS+BA5mg/l+NAA0.5mg/l during subculture of L.sprengeri, L.squamigera.

石蒜属植物快速繁殖技术研究中，在无菌无性系建立阶段：鳞茎以0.1％HgCl_2消毒10-12分钟效果最好，而叶、根尖、鳞芽等较干净部位选用0.1％HgCl_2消毒7分钟；用三种石蒜属植物的叶片、根尖、鳞芽及带基盘与不带基盘鳞片进行培养，以带基盘鳞片诱导分化效果最理想，鳞芽易培养出芽，但数量有限，而叶片、根尖与不带基盘鳞片均未诱导分化；带基盘鳞片为石蒜属植物快速繁殖最佳外植体，以鳞茎中部3-15层芽诱导率高，较外层稍次之，内部鳞片诱导率最低；选用八等分法、六等分法、四等分法切割鳞茎，六等分法综合效果最好；每外植体带三鳞片培养最为适宜；三种石蒜属植物各自适合的培养基成分不同，换锦花在MS+BA5mg／l+NAA0.1mg／l中培养效果最好，夏水仙为MS+BA5mg／l+NAA0.5mg／l，而白花长筒石蒜在各培养基组合中培养效果均不理想，其适合的培养条件有待于进一步研究。

And Aphelenchoides besseyi with distinct effects; the fermentation liquid of the bacterial strain has higher poisonous activity to second instar larva of Heterodera glycines, and can remarkably restrain cyst hatching; the treatment of fermentation liquid with different diluted concentration is significantly different from the treatment of sterile water; the insecticidal effects of stock fermentation solution can reach above 90%, and the effects of greenhouse experiment are obvious; at the same time, the bacterial strain can remarkably poison the Meloidogyne spp.

该菌株的发酵液对大豆胞囊线虫二龄幼虫具有较高的毒杀活性并显著抑制胞囊孵化，不同稀释浓度发酵液的处理和无菌水处理有显著差异，发酵原液的杀线虫效果可达到90％以上，温室防效试验效果明显。同时该菌株对根结线虫Meloidogyne spp。

It was then introduced by gene pulser into acrystalliferous strain CryB and a recombinant strain CryB (pBMBZGC10) was obtained. Different fermentative solutions of recombinant strain were used for multi-spray on leaves of Brassica pekinesis, Ipomoea aquatica and Lycopersicon esculentum. Results by using fluorescent detection and PCR amplification revealed that cry1Ac10 gene could not been detected in roots, stems and leaves of plants tested. The cry1Ac10 gene was also not transferred into indigenous bacteria, actinomyces and fungi in soil.

苏云金芽胞杆菌标记重组菌株与杀虫基因水平转移的研究将重组菌株CryB（pBMBZGC10）的发酵液按浓度梯度分次进行喷洒小白菜、蕹菜和番茄作为供试植株，利用标记基因研究的结果表明：cry1Ac10基因没有向供试土壤细菌、真菌和放线菌转移，也未在植物的供试植物根、茎和叶中检测到该基因。

Ganoderma species belong to the kingdom of Fungi, the division of Basidiomycota, the class of Homobasidiomycetes, the order of Aphyllophorales, the family of Polyporaceae and the genus of Ganoderma.

The results show that garlic, ginger, onion extract on the tested bacteria were inhibited, extract three kinds of mixtures can enhance the inhibitory effect, that is a synergistic to garlic: 2:1 onion and ginger : onions: garlic for 2:1:1 complex inhibitory effect of matching the most obvious;In addition to Ginger: onions: garlic for Rhizopus outside of 1:2:1, ginger + onion + garlic compound of the MIC are 0.21mg/mL, obvious synergy, there are broad prospects for development and utilization.

结果表明，大蒜、生姜、洋葱提取液对供试菌均有一定的抑制作用，3种提取液复配后，可以增强抑菌效果，即具有协同效应，以大蒜：洋葱为2：1及生姜：洋葱：大蒜为2：1：1复配对抑菌效果最为明显；除生姜：洋葱：大蒜为1：2：1对根霉外，生姜+洋葱+大蒜复配的MIC都是0.21mg/mL，协同效应明显，具有广阔的开发利用前景。

By the way, osmanthus is susceptible to oak root fungus and I have had at least six big ones died for the same cause. The problem with oak root fungus is you do not know when the osmanthus roots may touch and contract the fungus. Once it gets it, we have to cut off the infected area and move it to a container. My two pot-grown ones are the survivors of the fungus.

顺便一提，桂花易於感染oak root菌，我至少有六大盆死於此因，对於此菌的麻烦，就是你不会知道桂花的根何时接触这个菌种，一旦染上，就必须切除受感染地方，移到另一个容器，我两盆种的就是染菌后的幸存者。
