2. Pay attention to prevent freezing damage during the planting process. Don't plant too late in autumn. On the one hand, it is not conducive to the healing of root wounds. On the other hand, it is easy to suffer from early frost during the planting process and cause dead seedlings. 3. Walnut trees planted in autumn must be buried in soil for winter. Buried soil can prevent low-temperature freezing damage in winter, but also prevent the spring. 4. Walnut trees planted in autumn must also be watered thoroughly after planting. After the soil is removed and straightened in the second year, water should be refilled in time and managed according to the management methods for tree planting in spring.

5.Specific Gravity range more suited to animals
[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.

Precautions for planting walnuts in autumn
1. It is advisable to plant walnut trees sooner rather than later in autumn. The earlier the planting, the higher the ground temperature, the better the healing of walnut root wounds and the growth of new roots, and the growth of walnut seedlings in the second year.
