Planting fruit trees is generally suitable for spring and autumn, and the best period for planting is to plant the fruit before and after the planting. At this time, the tree is in a relatively dormant state, the body stores more nutrients, the roots and branches of the wound (notched) easier to recover, nutrient consumption and water transpiration is minimal, the survival rate is high.
Autumn planting refers to the planting of the saplings before the land is frozen. Spring planting refers to planting soil in the spring after thawing until the fruit trees are germinated, generally in late March or early April (preferably before and after Ching Ming Festival). According to different tree species characteristics, planting time should also be different, peach, apricot, plum, etc. should be early, red dates, etc. should be late, generally planted immediately after soil thawing is appropriate. Spring planting can avoid the overwintering management link of autumn planting, centralized operation, convenient management, and relatively labor saving.

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.
