Detection principle
1. pH: The pH value in the range of 5-9 is measured by the pH indicator, and the pH value of the fresh urine of a normal person is between 5-7.
2. Nitrite: The reaction is based on the reduction of nitrate to nitrite by Gram-positive bacteria in the urine. The nitrite reacts with p-aminobenzenesulfonic acid to form diazonium compounds, which are then combined with N-(1-naphthalene) )-3 aminopropanesulfonate combined with a pink color.
3. Glucose: According to the reaction principle of glucose oxidase, glucose oxidase specifically oxidizes glucose to generate glucuronic acid and hydrogen peroxide. Under the action of hydrogen peroxide, hydrogen peroxide oxidizes the indicator and turns color. .
Classification
Urinalysis test strips are divided into visual series and machine series. The visual inspection series is divided into several models according to different inspection items; the machine inspection series is divided into several models according to different applicable instruments.
1. Classification by measurement method
1) Visual inspection series
When observing the result, compare the color with the standard color code within the time specified on the color code, judge and read the result.
2) Machine test series.
For instrument operation, refer to the instruction manual of the Urine Analyzer used.
2. According to the number of measurement items
There are single-item, 2-item, 4-item and multiple test strips. Currently, 10-item or 11-item multiple test strips are most commonly used in hospitals.
3. Classification by structure
Urinalysis test strips with single-layer membrane structure and multi-layer membrane structure.
Ginkgo fungus three-dimensional cultivation
In recent years, Ginkgo biloba cultivation has grown from traditional sporadic cultivation to large-scale production and intensive production. The area of ​​Ginkgo biloba and Fengchan Park has increased year by year. The ginkgo leaf collection garden fungus inside, fungus fruit body respiring release of carbon dioxide supplement Ginkgo photosynthesis needs, Ginkgo photosynthesis for the growth of edible fungus to provide adequate oxygen, fungus bacteria return to field, fertility, promote ginkgo growth, Ginkgo biloba growth Providing a cool climate, the two complement each other and produce a good harvest. 1. Ginkgo cultivar 1. Ginkgo biloba ginkgo cultivating leaf garden was built to achieve good quality and high yield leaves. When constructing a garden, it is necessary to choose leeward sunny land, fertile land, convenient land for irrigation and drainage, deep-turning and soil improvement, and sufficient use. Organic Fertilizer. 2. Seedling construction Ginkgo biloba seedlings in ginkgo leaf collection garden should be selected for low crown, multiple branches, short internodes of branches, dark leaves, thick and large leaves, large amount of leaf, ginkgo biflavonoids, bitter lactone, etc. Ginkgo cultivars with high levels of pharmacodynamic components are suitable for close planting. Ginkgo biloba has a high commodity value and can be used to increase production and income. 3. After planting leaves with Ginkgo biloba (leaf garden) site selection, cultivating and cultivating, planting in north-south direction will be conducive to lighting and ventilation. Ginkgo colonization method uses hole planting or furrow planting, spacing 50,100 cm or 40,120 cm. The survival rate of Ginkgo biloba colonization was the highest when the leaves buds were exposed before the “Changming Festivalâ€. After planting, the water was filled to ensure the survival of the seedlings. 4. Management Ginkgo leaf collection garden is mainly harvesting leaves. Strengthening underground management, controlling pests and diseases, timely fertilizer application, spraying foliar fertilizers, and applying effective nitrogen fertilizers are key measures to increase the yield of Ginkgo biloba. Second, fungus cultivation 1, strain preparation: fungus seed production technology and conventional edible fungi the same. 2. Fungal management: The culture medium for agaric fungus can be adapted to local conditions and locally sourced, using cottonseed husk or mixed wood chips as the medium. From April to May, according to the formulation of the medium, the materials were filled with low-pressure polyethylene bacteria bags. Each bag was loaded with about 150 grams, and was sterilized at room temperature for 10 hours. After cooling, the fungus was inoculated under sterile conditions to produce the species. After inoculation, Bacteria bag into a pot, put indoors in sterile ventilation conditions, 30-40 days can be full of bacteria. 3. Fungus entering the garden: In June, the ginkgo leaf collection garden has a good shade effect, which is suitable for the growth and development of the auricular fruit bodies. When the fungus fungus bags are all made to pass through the bacteria, they are arranged for earing. 1 fungus into the park: Ginkgo leaf picking row spacing 100 cm or 120 cm, two rows of fungus between each row. In combination with ginkgo garden watering, the planting ditch first fills the bottom water, and after the water penetrates, the fungus fungus pieces that pass through the bacteria are bagged, laid horizontally in the planting ditch, or the two bags are placed in parallel in the longitudinal direction, and the bacteria pieces enter the ditch. After covering 1-2 cm thick fine soil, the bacteria block tight, and then spray a large water, requiring spray thoroughly. 2 ears management: June-July, high temperature, high humidity, suitable ear fungus growth, this period requires the insistence of water spray, humidity, pest control, can not flood irrigation, fine spray, spray. Fungus blocks into the field, about 7-8 days to ear, 15-20 days after ear ear softens, you can harvest. Fungus should be promptly cleaned after harvest (scrape residue, debris), re-spray the water out of the second, a total of 3-4 ears. From September to October, the growth of fungus was stopped before the harvest of Ginkgo biloba, combined with the autumn cultivator, the bacillary dysentery was returned to the field and fertility was cultivated. Comprehensive Benefits Ginkgo biloba leaves in the garden as fungus, double harvest. According to test statistics, the income of Ginkgo biloba per acre is 8,600 yuan, the total income of fungus is 6,000 yuan, and the total annual income is 14,600 yuan. At the same time, through the return of fungus aphid to the soil, increase the content of soil organic matter and beneficial microorganisms, improve the physical and chemical properties of the soil, from the traditional single planting to the development of ecological agriculture, is another new attempt in the comprehensive management of ginkgo.
