In use of the protein composite crystal culture box, taking out the crystals is avoided, and the crystal culture box can be directly and laterally erected on an X-ray diffraction instrument.

The present invention is a herbicide composition containing atrazine, which includes an active ingredient; the active ingredient includes an active ingredient A and an active ingredient B, the active ingredient A is atrazine (Atrazine); the active ingredient B It is a compound with the structure of formula I and a pharmaceutically acceptable salt thereof; wherein, the mass ratio of active ingredient A to active ingredient B is 10:1-80. The herbicidal effect experiment proves that when atrazine and the compound of formula 1 are combined as the active components of the herbicide for weed control, the two herbicide active components produce a synergistic gain effect. The herbicide composition can be used to control weeds such as barnyardgrass, crabgrass, quinoa, and amaranth in sorghum fields, but it is very safe to sorghum; it can reduce the amount of atrazine, reduce the residue in the soil, and at the same time inhibit the production of atrazine The resistant crabgrass also has excellent control effect.

The invention provides a method for preparing homogenesis composite film by spiral fiber in coconut fiber and its application. The method for preparing homogenesis composite film by spiral fiber in coconut fiber is characterized by comprising the following steps: completely immerse the coconut fiber in 0.2-5 g / LNaOH solution at 60-98 DEG C for 10-60 minutes according to the bath ratio of 1: 30-1: 50; after stirring and synchronous ultrasound vibration for 0.2-2 hours, filter and obtain a unicellular fiber wet screen; perform extrusion, fluid exhaustion and multi-grade traction process on the obtained unicellular fiber wet screen through 2-4 grade traction zones consisting of 3-5 pairs of rollers; clean the obtained submicron spiral fiber pulp circularly and perform the natural disordering wet formation for 1-3 times; and then directly soak clean pulp or dried clean pulp to cellulose original liquid with weight concentration of 2%-50%; separate out and solidify submicron spiral fiber pulp and cellulose by buffer liquid; obtain the homogenesis composite film. The homogenesis composite film can be used as the biomedical flexible cellulose composite material, or ecological, functional and comfortable elastic film material.
