Each starch reagent has its own mode of action on mineral surface, such as primary starch mainly by hydrogen bond, cationic starch by the co-action of hydrogen bond and electrostatic force (for minerals with negative charge on its surface), while carboxymethyl starch, hydroxamic acid starch and dialdehyde starch principally by chemical force accompanied with hydrogen bond and electrostatic force in part. Such chemical forces ensure the close adsorption of reagent on diaspore surface and enforces the hydrophilic of mineral surface. Also the branched chain enable the starch to cover the collector adsorbed on mineral surface, so as to depress diaspore furthermore.

不同淀粉药剂在矿物表面表现不同作用，原淀粉主要是氢键的作用，阳离子淀粉是氢键和静电力的共同作用，羧甲基淀粉、羟肟酸淀粉和双醛淀粉离子性药剂与矿物间的作用除了氢键、静电力外，更重要的是与矿物表面金属离子间产生的化学作用，使药剂能牢固地吸附在一水硬铝石矿物表面，增加矿物表面的亲水性，同时，淀粉支链结构的存在，使它能够掩盖吸附的捕收剂，达到抑制一水硬铝石的目的。

The inhibiting effect of 13 fungicides on the pathogen of wheat sharp eyespot was tested in vitro. The results indicated that Diniconazole, Jinggangfmycin.

The flotation mechanism of MG reverse-floating dolomite was studied by measuring the Zeta-potential of collophanite and dolomite, Infrared Absorptions Spectra analysing the adsorption of MG onto the minerals surface, ultraviolet- visible light absorbing spectrum calculating the amount of MG which was adsorbed onto the minerals surface. These researches showed that MG was more easyly adsorded onto the surface of dolomite in feeble acidic solution because of pure dolomite charges positive as well as pure collophanite charges negative. Therefore, a lot of MG negative ions was adsorded onto dolomite, and that MG negative ions contained hydrophobic group, the hydrophobicity of dolomite was modified, the grains of dolomite were adhered to air bubble and float with them.

对白云石和胶磷矿的Zeta-电位测定、红外光谱分析MG药剂在矿物上面的吸附情况、紫外-可见吸收光谱测定矿物上MG的吸附量等，研究了MG药剂反浮选白云石的浮选作用机理，表明在弱酸性条件下，由于白云石表面荷正电而胶磷矿表面荷负电，带有羧基和羟基官能团的MG药剂更容易吸附在白云石上，使其周围吸附有大量的MG负离子，而MG负离子的另一端为烃基，这就改变了白云石的疏水性，使其矿粒容易附着于气泡上浮。

Reduced the effect of Elixir of Mongoose and Elixir of Major Agility.

Also investigated were pharmacology of the two fungicides in wheat and their mechanisms inhibiting Rhizoctonia cerealis in vitro.

与典型的内吸性药剂克百威和非内吸性药剂福美双对比试验分析，首次证实绿帝在小麦植株上具有内吸性。

The EC50 values of procymidone and Junduqing were more than 10g/mL. At the concentration of EC50, all the tested fungicides did not affect the number of sclerotium. But the weight of sclerotium fell more than 70% after treated with triazole fungicides. All the triazole fungicides had no effect on the germination of sclerotium below the concentration of 10μg/mL.

在EC50值浓度下，所有供试药剂对菌核形成及其数量均没有影响，但三唑类杀菌剂对菌核单重影响较大，各处理所形成的菌核单重降低率均在70%以上；而当药剂浓度在10μg/mL以下时，己唑醇等三唑类杀菌剂对菌核萌发均没有影响。

The 9 common used insecticides of cypermethrin 4.5%EC, omethoate 40%EC, chlorpyrifos 40%EC, acetamiprid 3%EC, imidacloprid 10%EC provided excellent control for wheat aphids in fields. The control effects were over 90% at 7 days after spraying. The 9 insecticides had bad effects on aphidius and coccinellidae in three days after spraying and the number of two natural enemies decreased rapidly. But on the 7th day, the number of the two natural enemies increased and there were difference between those treated with imidacloprid, acetamiprid and abamectin and CK. BT had no evident difference compared to the control.

为了明确杀蚜药剂对麦蚜的防治效果、适宜的防治时期、对生态环境安全性和粮食作物食品安全性的影响，对4.5%氯氰菊酯、40%氧化乐果、40%毒死蜱、3%啶虫脒、10%吡虫啉等9种防治麦蚜的药剂进行了筛选，发现各药剂对麦蚜的防效较好，喷药后7d防效均在90%以上。9种农药在喷施后的3d内，对麦蚜的主要天敌蚜茧蜂和瓢虫影响较大，两种天敌数量锐减，但到7d时各处理蚜茧蜂数量均有回升，其中不同剂型的吡虫啉、啶虫脒和鲁植顺克处理的蚜茧蜂数量同对照相差不大。

Four substances including 2-methyl ethyl acetoacetate and barley straw extract distilled from bulrush as well as cetyl trimethyl ammonium bromide and isothiazo lintone were used for the comparison experiment in inhibiting the growth of Microcystis aeruginosa in various phases. Result showed that inputting chemicals in the lag phase has better effect than in the log phase, and adding in lag phase can effectively inhibit the algae growth. Although feeding allelopathic substance at log phase can lead to certain restraining effect, it cannot result in the effective inhibition of algae growth, which can be well achieved by feeding CTAB and isothiazo lintone below 10mgl/L during log phase.

研究用从芦苇中提取的2-甲基乙酰乙酸乙酯和大麦秸浸出液两种化感物质以及十六烷基溴化钱和异噻唑啉酮等四种药剂对不同生长期的铜绿微囊藻进行了对比抑制试验，结果显示在铜绿微囊藻生长的迟缓期投加试验药剂效果比在对数期投加效果都好，在迟缓期投加四种药剂，都有很好的抑藻效果；在铜绿微囊藻生长的对数期投加化感物质，虽然有一定的抑藻率，但效果较差，而在藻对数期投加10mg/L以下的CTAB和异噻唑啉酮能达到很好的水华抑制效果。
