White radish is a common rhizome vegetable in the countryside. It can be eaten with broken nails. It is sweet and crunchy. If you eat it regularly, you can digest it, nourish the stomach, remove diseases, nourish lungs, detoxify the body, and diuretic. Rural cultivation, and pay attention to the amazing yield of planting techniques, then what are the high-yielding techniques for white radish? Let ’s check it out together! White radish growing method I. Variety selection: The radish sown in April to May should be selected for cultivars with strong winter characteristics and short growth period; the ones sown in June to July should be selected for cultivars with high heat resistance and short growth period. II. Cultivated land selection: The environment of cultivated land directly affects the yield of white radish. Generally, sandy loam soils with no pollution, fertility, looseness, water and fertilizer retention, and soil pH values ​​from slightly acidic to neutral should be selected. Continuous cropping with cruciferous vegetables should be avoided as much as possible, and the soil should be plowed and deepened as soon as possible to fully break the rake to make the soil loose, so as to facilitate the normal sitting length of radish meat roots. White radish high yield cultivation tips 3. Soil preparation: plow the layer deeper than 35 cm, and remove the rubble and rubble in the soil to reduce the occurrence of radish branch roots and branch roots. After deep plowing, flatten it thoroughly and apply 3,000 yuan per acre of cooked farmhouse fertilizer. 5000 kg, 30 ~ 40 kg of compound fertilizer, 100 kg of plant ash, 25 ~ 30 kg of superphosphate, and 200 g of high content boron fertilizer or 1 kg of high-quality boron fertilizer can be added to the base fertilizer to prevent boron deficiency caused by radish. Black skin and black heart can also increase the use of quicklime to adjust acid and calcium, reducing disease occurrence. After the application, prepare the hoe for hoeing. The hoe is 25-30 cm high, the ridge is 1.2 to 1.5 meters wide, and the ditch is 35 cm wide. 4. Sowing: It is generally recommended that planters should cover with plastic film before sowing in mid-May to increase ground temperature and prevent early pumping. Sowing from late May to August may not require mulching. In spring, the surface can be covered with a film for thermal insulation, and in the summer and autumn, a sunshade net can be used to cover the floating surface in order to keep moisture and prevent rain erosion. White radish growing tips V. Field Management ①Seedling management: seedlings grow fast, the seedlings need to be checked once after 4 to 5 days of seeding, and if there is a lack of bacteria, they should be replanted in time to maintain the seedlings. If mulching is used for seeding, it is necessary to break the film and release the seedlings after emergence. ② Topdressing: Seedlings with 2 leaves and 1 heart are topdressed with 3 kg of urea per acre, and 5 leaves and 1 heart are topped with 5 kg of urea and 5 kg of potassium sulfate per acre. Fertilize the water according to the growth situation, and apply or spray compound fertilizer with the water. ③ Watering: If the dry soil is dry after planting, it must be watered immediately, and most of it will be watered again when it emerges. Watering during high temperature and drought at seedling stage, and pay attention to drainage and waterlogging prevention. ④ Harvest: Harvest in time after sowing. Choose to harvest on a sunny evening or cloudy day, pull out the radishes, remove the cherry blossoms, clean, classify, package, pre-cool and transport them to the consumer market.

This standard specifies the terms and definitions, classification, technical requirements, test methods, identification, labels and instructions for use, packaging, transportation and storage of nucleic acid extraction kits (magnetic beads method) (hereinafter referred to as "kits"). This standard It is suitable for extracting and purifying human genomic nucleic acid and its fragments from various clinical samples such as serum, plasma, whole blood, cerebrospinal fluid, milk, saliva, urine, sputum, swab, tissue or paraffin-embedded tissue by magnetic bead method , Pathogen nucleic acid kit. Pathogen nucleic acid includes deoxyribonucleic acid (DNA), ribonucleic acid (RNA), etc. This standard does not apply to nucleic acid extraction reagents contained in closed systems that cannot extract nucleic acid extraction products for detection.
This kit uses magnetic beads with unique separation function and a unique buffer system to separate and purify high-quality virus from serum, plasma, lymph, cell-free body fluid, cell culture supernatant, urine or various virus preservation solutions DNA/RNA. The uniquely embedded magnetic beads have a strong affinity for nucleic acids under certain conditions, and when the conditions change, the magnetic beads release the adsorbed nucleic acids, which can achieve the purpose of rapid separation and purification of nucleic acids. The whole process is safe and convenient, and the extracted viral DNA/RNA has high yield, high purity, stable and reliable quality, and is especially suitable for automated extraction of high-throughput workstations. The nucleic acid purified by this kit can be applied to various routine operations, including RT-PCR, fluorescence quantitative PCR and other downstream experiments.
