French Lilies, also known as artichokes, Jerusalem artichokes, etc., are currently grown in Europe and America. The edible parts are the total buds and receptacles of the buds, and they have the health function of promoting amino acid metabolism and lowering cholesterol. First, sowing nursery. Seed sowing in the middle and late March, with 600-800 seeds per acre, the seeds should be soaked in water at 55°C for 30 minutes, do not disable the wooden stick to stir the seeds, soak the seeds for 12-16 hours when the water temperature drops to room temperature, and then fish. Rinse with clean water and then wrap it in wet cotton cloth, put it under 20°C temperature, germinate until the seeds are white and sow. Use a 72-well plastic tray or a 6 cm 6 cm nutrient bowl to raise the seedlings with peat and vermiculite as the substrate. Seedling temperature 18-20 °C, watering as little as possible, appropriate fertilizer and foliar spray fertilizer. 40-45 days of seedling age, when the seedlings have 5-7 true leaves can be planted. Second, site preparation. Choose lands that are well-drained and excreted to be cultivated, each cultivating crushed and crushed organic fertilizer more than 3,000 kilograms, cultivating depth more than 25 centimeters, and after forming a small sorghum that is 50 centimeters wide and 20 centimeters high, with an interval of 1-1.5 meters per paving. Film insulation. In spring, the ground temperature is stable and can be planted above 12°C. Each row is planted with 1 row, 80-100 cm of plant spacing, 500-800 plants per acre, and planting depth of 20-25 cm. Third, field management. Plants with more than one year in the mid-March and May of each season had a single application of fertilizer. Each acre had a special vegetable fertilizer of 30 kg or 150 kg of active organic fertilizer and 10 kg of potash. The planting plants planted the first fertilizer 15 days after the seedlings were planted, and then applied a special vegetable fertilizer of 20 kg per acre for about 30 days. In the spring, from the beginning of pumping stems to harvesting buds, it is necessary to water in a timely manner, usually about 10 days, and timely drainage after rain. In the spring, there is a danger of small ground tigers and aphids. It can be used to control roots and spray imidacloprid in 500 times of the mixture of Ipoh. Fourth, harvest. More than one year old plants began to harvest buds from the beginning of May until the end of June. It is advisable to harvest 1-2 days before the opening of seed pods. The premature yield is low, and the commodity value is too late. After harvesting, loosen the soil around the plant, cut off the stems at a distance of 10 cm from the ground, and then cover the soil so that the number of tillers increases and grows.
