Leek is the most common vegetable in rural areas. If you just grow and eat and pick at your own home, it is actually quite easy to manage. If you want to grow leek in a large area for sale, then the correct fertilization method can make it grow well and fast. Let's take a look at the planting time and method of leeks.
Time and method of fertilizing leeks
1. Nursery period
When leeks are planted, 8000-10000 kilograms of fermented stable manure and 40-60 kilograms of superphosphate are applied per acre of seedbed. The fertilizer is evenly spread on the surface of the soil and then plowed and flattened for border sowing. After the leek seeds emerge, combine with watering, apply thin human feces 2 to 3 times, and then transplant them in time. Fertilize leeks during the nursery period. Remember to apply water and fertilizer at the same time to avoid fertilizer damage.

2. Transplanting period
When transplanting leeks, the base fertilizer is generally 8000~10000 kg of fermented and mature manure per acre, 400~1000 kg of fermented and rotten cake powder fertilizer, 80-100 kg of superphosphate, 40-60 kg of potassium sulfate, and then plow the land. Rake flat, do border planting and planting. After planting, water the planting water immediately to avoid uneven use of base fertilizer, which may cause fertilizer damage and burn roots.
3. Growth period
Fertilization in the first year after planting: Water the leeks immediately after planting to ensure the survival of the seedlings. After the new leaves of leeks appear, 1,000 to 2,000 kilograms of human excrement or 15 to 20 kilograms of urea per acre is watered. Autumn is the most suitable season for leeks to grow. You should use 20 to 26 kilograms of ammonium sulfate per acre at intervals of 10 to 15 days, or use 2,000 to 4,000 kilograms of human urine and feces that are thoroughly fermented and decomposed.

4. Fertilize after the next year
In the spring of the second year, the leeks will turn green. After the new seedlings are unearthed, water 1000-2000 kg/mu of thin human excrement, or topdressing with 6-10 kg/mu of ammonium sulfate for fertilizer. When the leek seedlings grow 12 to 15 cm tall, 2,000 to 3,000 catties of human excrement are flushed with water per acre. When the leek seedlings are 15 to 18 cm high, water them once. Since then, every time leek is harvested, after the harvested wound has healed, new leaves must be fertilized and watered once. Remember not to topdress the wound immediately after harvest to avoid fertilizer damage. When top dressing leeks, you can use organic fertilizer and chemical fertilizer alternately. Use organic fertilizer and water to wash 2,000-3,000 kilograms of human excrement per acre, or use 18-20 kilograms of urea, or use 30-40 kilograms of ammonium sulfate.

China has become the world's largest producer of Antipyretic And Analgesic drugs. The output of aspirin, paracetamol, analgin and other varieties has exceeded 10,000 tons, and the output of phenacetin, aminopyrine, antipyrine and other varieties has exceeded 1,000. Ton. At present, the output of Antipyretic analgesics in my country is growing rapidly, and it is expected to grow at a rate of about 8% in the future. The production of intermediates for antipyretic and analgesic drugs is large, and there are many manufacturers. With the growth of antipyretic and analgesic drugs, their intermediates have also developed by leaps and bounds.
In 2003, the domestic consumption of paracetamol increased rapidly, and the export also showed a rapid growth momentum. The export volume was 28,163 tons, and the annual export volume increased by about double. In the first half of 2004, although its export growth slowed down, it still increased. From January to May 2004, the export volume of paracetamol was 12,501 tons, slightly higher than the same period last year. Para-aminophenol is an important intermediate in the synthesis of paracetamol, which is growing rapidly. The annual output of p-aminophenol in my country is 32,000 tons. It is estimated that by 2005, the domestic production of paracetamol will reach more than 50,000 tons, and the pharmaceutical industry will consume 45,000 tons of p-aminophenol. The total demand for phenol is about 50,000 tons, the market gap is large, and the development and utilization prospects are broad.
