Variety selection. It is best to use fast-growing varieties such as purple skin garlic or white-skin garlic, such as purple garlic, bamboo garlic, Baigong garlic, etc. The garlic produced by this kind of garlic grows robustly, is neat and cold-resistant, and has strong disease resistance. The output is high. Choose the vegetable plots, open spaces or indoor free rooms in front of the house, and use bricks to form high (deep) 60 cm. The length and width are determined according to the cultivated land and the number of cultivation.

Use a garlic with a large flap and a uniform size and a positive color. Peel off the coat, remove the rotten petals, garlic cloves, garlic cloves, soak for 18-24 hours with water. Place the garlic cloves in the pool (or on the clams), the top should be flush, and then cover the moist fine sand or sandy loam with a thickness of about 2-4 cm. The garlic is about 15-20 kg per square meter.

Generally, it can be continuously produced from cold dew (early October) until the second spring equinox (late March). When most of the garlic sprouts grow out, cover the grass on the pool (the closed window door for indoor cultivation). When the seedling height is about 10 cm, spray water once every 1-2 days. Direct cultivation of alfalfa, 1-3 days after planting, garlic buds, when you want to cover the grass cover shading, soften the garlic leaves, promote their yellow growth.

Before unearthing, the temperature during the day is controlled at 25 ° C, 18-20 ° C during the night; after the garlic is unearthed, the daytime temperature is at least 18-22 ° C, and not less than 16 ° C at night. When the seedling height is more than 24 cm, the temperature is maintained at 14-18 ° C, and it can be reduced to about 12 ° C 4-5 days before harvest.

Spray water once immediately after planting, and spray water every 4-5 days during the growth of the seedlings. In the early stage of growth, the amount of water is small, the late growth temperature is high, the seedlings are large or the sandy loam drains quickly. It should be drenched with water, and the water should be stopped 3-4 days before harvest to make the garlic yellow thick. Spraying once every other week with 0.1% potassium dihydrogen phosphate or 0.2%-0.3% aqueous urea solution is beneficial to increase the yield.

Softening cultivation of garlic and garlic generally does not reveal the straw curtain. If the garlic is snowy white, you can choose to open the pool or the arch shed at noon on the sunny day to improve the color and quality. If there is high temperature and high humidity, it should be ventilated to prevent rotten seedlings. It can be harvested 20-25 days after cultivation and 36-43 cm high in garlic. After another 20 days or so, the second one can be harvested. After the general cultivation of garlic and yellow sorghum, the garlic should be taken out, and after taking out the sand and the whole hoe (or pool), grasp the second seeding.

Single Use Sampler

Single-use samplers are used for sample collection, transportation and storage, etc. Sampling swabs are composed of Swab rods or swab heads, and are divided into cotton swabs or flocking swabs. The swab head is made of chemical fiber (polyester, rayon, etc.), nylon and other non-cotton, non-calcium alginate materials; the swab rod is made of PP, PS, ABS and other non-bamboo/wood materials. The breaking point is located about 3cm and/or 8cm (or any position) from the tip of the swab, which is easy to break.
