    • The dispenser draws a concentrate fluid from a liquid container into an input fluid. There is an elongated channel having an input for the input fluid and dispensing nozzle at an exit end for dispensing the concentrate fluid in a diluted form. A transverse intersecting channel is intermediate the input end and the exit end. An insert is moveable in the transverse intersecting channel, apertures of the moveable insert being alignable with apertures in the transverse intersecting channel and the liquid container. The channels from the liquid container will have a plurality of various sized apertures to provide for the flow of differing amounts of concentrate fluid into the input fluid. By adjusting the moveable insert in the transverse intersecting channel and/or the input fluid flow rate the concentration of concentrate fluid in the input fluid is changed.
    • 分配器将浓缩液从液体容器吸入输入流体。 具有细长通道,其具有用于在出口端处的输入流体和分配喷嘴的输入,用于以稀释形式分配浓缩液。 横向相交通道位于输入端和出口端之间。 插入件可在横向交叉通道中移动,可移动插入件的孔与横向相交通道和液体容器中的孔对准。 来自液体容器的通道将具有多个各种尺寸的孔,以提供不同量的浓缩液流入输入流体的流量。 通过调整横向交叉通道中的可移动插入件和/或输入流体流速,改变输入流体中的浓缩液的浓度。

    • The invention belongs to the technical field of genetic engineering of agricultural microorganisms. Specifically, the invention relates to producing and using gene cluster for thuringiensin synthesis from Bacillus thuringiensis. The gene cluster includes 11 genes of thuA, thuB, thuC, thuD, thuE, thuF, thuG, thu1, thu2, thu3 and thu4. These genes have the nucleotide sequence as shown in SEQ ID NO: 1. And the thuringiensin biosynthetase encoded by these genes have the amino acid sequences as shown in SEQ ID NO: 2-12. The genes according to the invention and the proteins encoded by those genes can be used as new nucleosides lead compound of pesticide library and provide new target for developing insecticides. In practical use, a series of new, efficient and low toxic insecticide can be obtained by structure modification.
    • 本发明属于农业微生物遗传工程技术领域。 具体地说,本发明涉及生产和使用苏云金芽孢杆菌的苏氨酸素合成基因簇。 基因簇包含thuA,thuB,thuC,thuD,thuE,thuF,thuG,thu1,thu2,thu3和thu4等11个基因。 这些基因具有如SEQ ID NO:1所示的核苷酸序列。由这些基因编码的苏云金素生物合成酶具有如SEQ ID NO:2-12所示的氨基酸序列。 根据本发明的基因和由这些基因编码的蛋白质可以用作农药图谱的新核苷酸铅化合物,并提供开发杀虫剂的新靶标。 在实际应用中,通过结构修饰可以获得一系列新型,高效,低毒的杀虫剂。
