The invention discloses a diazepam lipocalin mimetic antibody, and the DNA sequence expressing the antibody is the sequence shown in SEQ ID NO.1 in the sequence list. The diazepam lipocalin mimetic antibody of the invention lays the foundation for realizing the rapid detection of diazepam. In lipocalin, the embedding rate of the recognition site that can interact with the target molecule is as high as 95% in the protein, while the embedding rate of the binding site in the antibody molecule is only 66%. This is due to the large mutual contact surface within the lipocalin molecule that can bind to the target molecule (Ingo, 2003). Lipocalin has a simple structure, small molecular weight, a large recognition site that can bind to target molecules, and a stable skeleton, which has unique advantages compared with antibodies.

The invention belongs to the technical field of agriculture, and in particular relates to a method for shaping and pruning sweet cherry columns suitable for labor-saving operations. The pruning method is as follows: (1) Erection of supports; (2) If the 2-year-old seedlings are used for colonization, the buds are carved to promote the directional branching, so that the small fruiting branches are distributed in a spiral shape; the new shoots are continuously topped; heavy pruning in winter (3) pruning of trees in the 2nd-3rd year of planting and full fruit stage (5) supporting technical measures; the present invention provides a sweet cherry cylindrical shaping and pruning technology for labor-saving operation according to the characteristics of gisela dwarfing rootstocks The pruned sweet cherry cylindrical shape of the present invention has a stable tree body skeleton and strong light transmission, which can make the branches see the light without excessive nutrient consumption; fast forming, early high yield, high-quality fruit rate; simple pruning method It is easy to walk, easy to pick, labor-saving; wide between rows for mechanized operation and high-density cultivation of facilities and other advantages.

The invention relates to a simple pruning method of a medlar tree. The method is based on a control method of 'single bud and branch + segmentation + fixed height', pruning is performed upward from the ground in units of segments, pruning is performed mainly with the control method of single bud and branch except for the first segment, and the height of the medlar tree is finally maintained at 150-180 cm. The pruning method not only can improve the yield and quality of medlar fruits, but also has the advantages that the rules for the pruning method are simple, a pruning worker learns and masters the method conveniently and does not make mistakes in the pruning process easily, the requirements for the pruning worker are reduced, and the labor efficiency of the pruning worker is improved; after the medlar tree is shaped, a mechanical means assists in pruning conveniently, for example, after one year of manual pruning, mechanical pruning can be performed for one year, thereby saving halfof the work, greatly improving the labor efficiency of medlar pruning and reducing the cost.

The invention relates to a 2,3'5,5'-diphenyl tetracarboxylic acid cadmium complex and a preparation method thereof and relates to the field of cadmium complex fluorescent materials. A chemical formula of the 2,3'5,5'-diphenyl tetracarboxylic acid cadmium complex is {[Cd2(bptc)(bih)(H2O)2].H2O}n, wherein bptc is 2,3',5,5'-diphenyl tetra formic acid anion ligand, and bih is 1,6-di(imidazole-1-) hexane. The preparation method of the 2,3'5,5'-diphenyl tetracarboxylic acid cadmium complex comprises the following steps: under hydrothermal condition, dissolving 2,3',5,5'-diphenyl tetra formic acid, an inorganic base, 1,6-di(imidazole-1-) hexane and a cadmium salt in water, adding the obtained mixed solution into a closed reaction still, heating to 120-160 DEG C at a speed of 10 DEG C per hour, performing heat preservation for 3 days, then cooling to room temperature under natural conditions, so that colourless massive crystals are generated, and then washing and drying, so that the target product, namely the 2,3'5,5'-diphenyl tetracarboxylic acid cadmium complex, is obtained finally. The 2,3'5,5'-diphenyl tetracarboxylic acid cadmium complex has stable fluorescence property and high yield, and the preparation method is simple, and has good repeatability.
