Garlic yellow pollution-free cultivation techniques in winter and spring
Garlic is a pollution-free vegetable that is welcomed by consumers in the winter and spring season. The production of garlic yellow does not require fertilization. It is based on the growth of nutrients stored in the garlic, as long as it maintains a certain temperature and timely shading or semi-shading can be successful. First, the choice of species. It is best to use the varieties that grow quickly in purple skin garlic or white skin garlic, such as purple skin garlic, bamboo garlic, white garlic, etc. The garlic yellow produced by such garlic grows robustly, is resistant to cold, and has strong disease resistance. High yield. Second, build the pool insulation. Choose the vegetable plot behind the house, open space or indoor leisure room, etc., use bricks to make a height (depth) of about 60 centimeters, and the length and width will be determined according to the cultivated land and cultivated quantity. Third, timely planting garlic. Choose a large and uniform garlic head with a large size. Remove the coat, remove the rotten flaps, garlic tray, garlic sprouts, and soak for 18-24 hours with fresh water. Place the garlic cloves in the pool (or bowl surface), the top should be flush, and then cover with moist fine sand or sandy loam about 2-4 cm thick, with garlic about 15-20 kg per square meter. It is generally produced continuously from cold dew (early October) until the second year of the spring (late March). When most of the garlic sprouts come out, they should be covered with grass shade (closed window doors for indoor cultivation). When the seedling height is about 10 cm, spray water once every 1-2 days. Direct cultivation of wolfberry, 1-3 days after planting buds exposed buds, then look for shelves to cover straw shade, soften garlic leaves, promote its yellow growth, to ensure product quality. Fourth, temperature management. Before excavation, the temperature was controlled at 25°C during the day and 18-20°C at night. After unearthed garlic bulbs, the daytime temperature was kept at 18-22°C at least, and it was not less than 16°C at night. When the height of seedlings is more than 24 cm, the temperature is maintained at 14-18°C and can be reduced to about 12°C in 4-5 days before harvest. Fifth, water management. Immediately after the plant was sprayed with water, the seedlings were sprayed with water every 4-5 days. Less water in the early stage of growth, high growth temperature in the later period, rapid drainage of seedlings or sandy loam, should be more watery, stop watering for 3-4 days before harvest, and make Garlic Yellow grow thick. Every other week or so, spraying with 0.1% potassium dihydrogen phosphate or 0.2%-0.3% urea solution once, will help increase production. VI, ventilation see light. Softening cultivation garlic yellow does not generally reveal the straw curtain. If the garlic yellow is snowy, you can choose a sunny day at noon to open the pool or shed to improve the color and quality. If there is high temperature and high humidity, ventilation is needed to prevent rotten seedlings. Seven, timely harvest. 20-25 days after cultivation (30-40 days for direct cultivation), Garlic Yellow can be harvested when the height is 36-43 cm. After about 20 days (about 30 days of direct cultivation), the second crop can be harvested. After the general cultivated garlic yellow has been harvested for two crops, the garlic should be taken out, and the sand and the whole crop (or pond) should be removed and the second crop should be planted.
