     TECHNICAL FIELD 
     The present disclosure relates to the technical field of agricultural bactericides, and in particular to a quinoline carboxylate compound and a preparation method and use thereof. 
     BACKGROUND 
     Bacterial diseases of crop plants are common diseases in agricultural production in China, and are even more harmful than viruses. Bacteria have been a major pathogen second only to fungi. Due to various transmission routes and lack of agents for control as well as long-term successive occurrence, there is increasing difficulty in controlling bacterial diseases. According to incomplete statistics, the current occurrence area of bacterial diseases in China is 120 million mu times, and the market for control of bacterial diseases has a capacity of over 2 billion yuan. 
     In the present agricultural production, agents for controlling bacterial diseases mainly include copper preparations (including organic or inorganic copper preparations) that are heavily used, and antibiotic products, wherein, the copper preparations have low efficacy for bacterial control, and many substances containing heavy metals are sprayed into the environment and thus pollute soil, water and food, causing safety concern over the environment and food; on the other hand, the heavy use of antibiotics may cause resistance of pathogenic bacteria in the human body to medical antibiotics. Only a few types of other agents can be used for treating agricultural bacteria, and can only be applied in a small area, limited by resistance and efficacy in practical production. Therefore, there is an urgent need for the development of a novel, safe and green chemical pesticide with low-toxicity and low-residue.

After cooling to room temperature, the above reaction system was added with water (20 mL) and extracted with ethyl acetate (10 mL×3). The organic phases were combined, washed with water (15 mL×2), washed with saturated brine (10 mL×1), and dried over anhydrous magnesium sulfate. The crude product was precipitated under reduced pressure, and purified by column chromatography (eluent: mixed solution of ethyl acetate, petroleum ether and formic acid (1:1:0.01)) to give the product (2.59 g, 81% yield).

     (3) Chlorophyll Content 
     The chlorophyll contents of leaves were measured by using a chlorophyll measuring instrument (model: SPAD-520 Plus). 
     The chlorophyll content increases were calculated according to formula (6) 
       Δ SP=SP 2− SP 1  (6),
 
     wherein:
         SP1-chlorophyll content before application;   SP2-chlorophyll content 14 days after application.

The compounds of the present disclosure have no adverse effect on the crops for tests, and are safe enough to meet the safety requirements of green pesticides. 
     Compared with the blank control, the compounds of the present disclosure have particular positive physiological effects on crops as follows: promoting the height growth of plants, stimulating the synthesis of chlorophyll and increasing the leaf area of the plants, so that the leaves of the crops are greener and thicker and thus improving the photosynthetic efficiency, which directly improves the immunity of the plants and the capability of resisting the adverse external environment, and makes the plants more robust. 
     4. Test for Controlling Soft Rot in Field 
     In October 2019, tests were carried out in fields of Chinese cabbage, wild cabbage and lettuce in Tai′an, Shandong. The doses of the compounds 152 and 282 of the present disclosure (both prepared as dispersible granules with a mass fraction of 10%) used were 16.87 ga.i./hm 2  and 33.75 ga.i./hm 2 , and the control agents used were 3% (by weight) wettable powder of zhongshengmycin and 33.5% (by weight) aqueous suspension of oxine-copper (both were commercially available). The dose of zhongshengmycin was 67.5 ga.i./hm 2 , and the dose of oxine-copper was 337.5 ga.i./hm 2 . Test and control agents were arranged in randomized blocks. Plot area was 15 m 2 . Treatment was repeated 3 times. The route of application was spraying on stem and leaves. The application was performed 2 times in total at an interval of 7 days, and the efficacy investigation was performed 7 days after the last application. During the investigation, sampling was carried out at 5 points in each plot. Disease conditions of soft rot in Chinese cabbages, soft rot in lettuces and soft rot in wild cabbages were recorded according to the relevant technical standard of  Pesticide Guidelines for the Field Efficacy Trials  GB/T17980.114-2004, and the incidence rate of plants was calculated to further evaluate the control effect.
