After the fall, greenhouse vegetables are generally pulled in the middle and late November. After the end of cultivation, they are cleared. In January, fennel continues to be planted in greenhouses and wintering cultivation is completed. It will end in March next year. It will be used as a greenhouse for spring cucumbers, spring tomatoes and other fruit and vegetables. Alas, this kind of efficient planting model has been promoted in Qing County for many years. The average economic benefit per mu is 4000-5000 yuan, and the higher one is 6,000 yuan. Its cultivation techniques are as follows: First, sowing time It is generally planted from early January until late. Second, species selection Choose fast-growing, cold-resistant, disease-resistant and high-yield varieties, such as aniseed in Inner Mongolia and local varietal cumin. Third, seed processing 1. Seeds. The fennel seeds are double-hanging fruit and contain two seeds. The seeds should be split before sowing. 2. Soak germination. Generally, fennel does not need to germinate. Seeding is faster at the time of sowing and germination can be performed. First, soak seeds in fresh water at 18°C-20°C for 24 hours, and then germinate the seeds in a cloth moistened with 20°C-22°C. Rinse the seeds once a day with fresh water and turn them once every 4-6 hours. When 80% of the seeds are "showy white" they can be sown. If it cannot be sown in time, store it at 10°C. IV. Preparation before planting 1. Before you go. Non-Umbelliferous vegetables. 2. Soil preparation. Deep plowing and ploughing, combined with site preparation, applied 3,000 kg of high-quality organic fertilizer, 6 kg of phosphate fertilizer (50 kg of calcium phosphate), and 5 kg of potassium fertilizer (10 kg of potassium sulfate). 3. Make a mistake. Make a width of 1.2 meters and break up the earthen material to make it even. Fifth, sowing Fill the bottom water. After the water has penetrated, cover with a layer of fine soil (or soil) and spread the seeds. In order to achieve uniform sowing, two sowings can be conducted. After the sowing, the cover soil is 1 cm thick and covers the small arch shed. Six, field management 1. Hang the sky. After sowing, hang a layer of plastic film 30-40 cm away from the outer film in the shed. The film thickness is 0.01-0.012 mm, which can increase the temperature in the shed by 2°C-4°C. 2. Temperature management. Before sowing until emergence, closed greenhouse insulation and cold. After emergence of fennel, when the seedlings height 7-8 centimeters, they begin to release winds, usually when the morning exceeds 22 degrees Celsius, the air is released, and in the afternoon, the air outlets are less than 20 degrees Celsius; in the mid growth period, the air is released at 8-9 hours; until the temperature reaches 20 degrees Celsius, the air outlets are closed; When the outside minimum temperature exceeds 3°C, it should be ventilated day and night. During the day, the tuyere should be large and the tuyere should be small at night. The maximum temperature during the day should not exceed 24°C, otherwise the fennel can easily dry. 3. Water and fertilizer management. About 20 cm high when the seedlings, water once, moderate water, combined with water, topdressing urea 10-15 kg per acre. VII. Pest Control In the early spring, fennel in greenhouses generally does not suffer from insect pests, and the disease is mainly anisocyanosis. At the beginning of the disease, spraying with 50% of Lekum Kang WP 800 times or 40% of Shijiale Suspension 1000 times spray. Eight, harvest When the seedling height is about 30 cm, it is harvested once.
(1) Hydraulic Patient Lifting Transfer Chair is Home Care Equipment (Household Medical Equipment), it can reduce the pain of bedridden patients, maintain the patient's self-esteem, reduce the work intensity of nursing staff, and reduce psychological barriers, so that Nursing staff can then spend more time and energy caring for patients.
