Iced ice, also known as ice grass, is a saline-alkali plant that grows on the coast. Because the liquid in the cells contains salt, the plants themselves are slightly salty. Because the surface of the iced dish is covered with liquid-filled vesicular cells that look like ice crystals, it is called iced. The iced leaves are thicker, which can lock the moisture tightly. The taste is fresh and crisp, and it can also be planted in pots. Let's take a look. 1. Prepare potting soil and seeds The basin is better prepared, the iced food is very skinny, we can use paper cups, washbasins, foam boxes when breeding, and you can buy special balcony vegetable planting containers if you have the conditions. Soil is relatively troublesome, we need to prepare some very breathable soft soil, because the ice seed is relatively weak, too thick soil can not grow out. Then sprinkle the prepared ice seed seeds evenly on it and gently coat a thin layer of soil, about 3 mm - 5 mm thick. 2, sprouting and sunning Iceberg seeds sprout very quickly, placed in a cool, ventilated place, generally can be seen within 72 hours of germination. Although the germination is simple, we must also ensure that the soil is slightly wet, and we can spray the surface of the soil from a distance every night. And iced vegetables are not the same as other vegetables. It will be long after seeing the sun after germination, so we must let it see the weak sunlight in time so that we can grow better. 3, seedlings and transplanting When the ice seedlings are longer and denser, we need to give them a seedling in time. Otherwise, if the seedlings are too dense, it will be prone to poor growth. When the ice seedlings grow to about 5 cm, they can be transplanted into large containers. It's also a very solid ice dish. The bigger pots and foam boxes are all right. It's about a distance of 10 cm to 15 cm. Remember that the transplanting steps should be done at night, but also soft, otherwise iced. The water droplets on the leaves are easily pinched. 4, fertilization The growth of iced vegetables requires fertile soil. When transplanting, we can put some fertilizer directly into the soil, and we need to operate it later in the province. You can use the diluted manure from your own home, or you can use microbial agents. After all, it is eaten by humans. Microbial agents are biological fertilizers that contain a lot of beneficial bacteria, which can improve the soil environment and grow for ice. Provide a lot of nutrients, and because it is purely biological, accidentally put more and will not burn root, very suitable for novices. The above is the planting steps and precautions of potted iced vegetables. It is tender and slag-free, crisp and refreshing. The price of iced vegetables on the market is not cheap. Friends who want to plant can refer to the above planting steps. For the wonderful pictures and hot comments about potted iced vegetables, you may be interested in the following recommended contents of Hui Nong. Welcome to read. 1. urine analysis strip is dry chemical reaction principle, the human body in the urine of white blood cells, proteins, ph, urine specific gravity, ketone body, bilirubin, occult blood, nitrite, uric bravery, glucose, creatinine, vitamin C, calcium within ten three indexes such as qualitative and semi-quantitative detection.
Rational use of urine analysis strip has played a very good role in our timely detection of disease and timely treatment
[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.

2. For the use of this product, we must pay attention to several points. For example, at the beginning, we should immerse all the reagent part on the urine analysis strip into the sample, and then take it out immediately.
3. Additionally, the edge of the urine analysis strip should be gently brushed along the mouth wall of the sample container to remove excess urine. Then place the reagent block on the urinalysis strip horizontally up and compare with the color map to record the results.
