Zaoyuan winter ploughing, especially the soil within the projection area under the canopy must be deep ploughed. The closer to the trunk, the shallower the ploughing, and the further away from the trunk, the deeper the ploughing, generally 15-30 cm is appropriate. In this way, the overwintering maggots and eggs in the soil can be turned out and frozen to death. This management measure can reduce the harm of various pests, such as jujube ruler, jujube spine moth, jujube mosquito, elephant beetle, red spider, scarab and peach heartworm.

Rapid test kits are designed for use where a preliminary screening test result is required and are especially useful in resource-limited settings.
• High quality
• Quick (10 minutes to 2 hours) and easy to perform .
• Tests based on agglutination, immuno-chromatographic, immuno-dot, and/or immuno-filtration techniques.
• Are suitable for individual or a limited number of samples, and require little or no additional equipment, which make them more economical than ELISAs in fully equipped laboratories.
• Possibility to store at room temperature for an extended period of time.
• Same-day results provide timely treatment possibility.
[Test Principle]
Urobilinogen:Urobilinogen with diazonium salt produce red violet dyes in strong acid medium.
Bilirubin:The direct bilirubin with dichlorobenzene diazonium produce azo dyes in acid medium.
Ketone:The acetoacetic acid and sodium nitroprusside cause reaction in alkaline medium,which produces red violet compound.
Blood:Hemoglobin acts as peroxidase. It can cause peroxidase release neo-ecotypes oxide (O).(O) oxidizes the indicator and make the color change subsequently.
Protein:It is based on a specific pH indicator attracted by cation on protein molecule,the indicator further ionized and make the color change.This phenomenon is called protein-error-of -indicator principle.
Nitrite:Nitrite and aromatic amine are diazotized to form a diazonium compound.The diazonium compound reacts with tetrahydrobenzo(h)quinolin 3-phenol produce the red azo dye.
Leukocyte:Pyrrole amino acid ester produce free phenol under the hydrolysis of esterase in neutrophile granulocyte,the free phenol couple with phenyl diazonium salt produce purple azo dyes.
Glucose:The glucose oxidized by glucose oxidase catalyzes the formation of glucuronic acid and peroxide hydrogen.Peroxide hydrogen releases neo-ecotypes oxide(O)under the function of peroxidase.(O)oxidizes tetramethyl benzidine, which make the color change.
Specific Gravity:Methyl vinyl ether and maleic acid copolymer is weak acid (-COOH) exchanger,the M+ cation (the major is Na+) in urine reacts with the exchanger and release hydrogen ion,hydrogen ion reacts with indicator produce color change.
pH:The method of pH indicator is applied.
Ascorbic Acid:Ascorbic acid deoxidizes the 2.6-dichlorphenolindophenol dye into colorless in alkaline medium.
Microalbumin:Sulfone phthalein dye has high sensitivity to microalbumin by the method of protein error.
Creatinine:Creatinine with 3,5-Dinitrobenoic acid produce violet compound in alkaline medium.
Calcium:Calcium ion reacts with methyl bromothymol blue produce color change in alkaline medium.
