First, the selection of varieties of bulbous fennel anniversary cultivation to choose cold, heat, fiber, crisp varieties. Second, the mouth arranging (a) Sunlight greenhouse winter and spring planting, from early November to early December planting, transplanting in early December to early January, harvest from the beginning of February to early March. (b) Plastic greenhouses "Double-membrane and oysters" in early spring. Sowing in early January, transplanting in mid-February, and harvesting in early April. (C) Plastic Liu Liuqiu delay. Seeding in early August, transplanting in early September, and harvesting in early November. (d) The temperature of the sun is higher than the winter temperature. Sowing in early September, transplanting in early October, and harvesting from late December to early January. Third, scientific seedling cultivation 1 mu bulbs fennel, seedlings need seed 100 grams. The seeds were first soaked in warm water at 20°C for 20 hours, and then they were germinated at a temperature of 22°C to 24°C and rinsed once a day. Seeds could be sown in 5 to 6 days. The seedbed is 12 meters long and 1.5 meters wide. The seedbed is fully screened with 30 kg of human and animal excrement, 5 kg of plant ash, 0.5 kg of NPK fertilizer, 5 kg of seedling fertilizer, and 3 g of soil fire fungus with green hen. Spraying seedbeds, the soil exterminator Shiyi Ning Shen Dan 100 grams. After the seedbed is leveled, it is irrigated with water. After the water seeps, the seeds are sowed with fine soil. After sowing, the street covered with 0.8 cm of fine soil was screened and sprayed on the seedbed with 2 grams of green hen. In the winter and spring season, seedlings are planted in greenhouses and need to be covered with plastic film and covered with small sheds (the plastic film is removed when 50% of seedlings emerge). After the seedlings were flushed, attention was paid to small winds. The noon temperature was maintained at about 24°C and the night temperature was maintained at about 13°C. Fourth, the fertilization of the earth stems and fennel should be deep in the soil, loose, fertile, sunny, irrigation and irrigation conditions in a good sandy loam soil cultivation. Each mu of high-quality fully cooked farmyard fertilizer 5,000 kg, 50 kg of organic-inorganic compound fertilizer, 25 kg of potassium sulfate, 1 kg of zinc fertilizer, 1 kg of boron fertilizer, 50% of the soil sterilization per mu application of Fujimi 1 kg, 80% One kilogram of carbendazim, soil exterminator 1.5 kg per mu Shiyi Nong Shendan. After fertilization, the land is made into a 1-meter-wide rake. V. Reasonable planting The winter and spring plants should be planted on sunny mornings. Summer and autumn plants should be planted on sunny days after 4 pm or on cloudy days. 1 meter wide pods, 3 rows, plant spacing 30 cm 25 cm, 7500 colonies per acre. When planting, small drops of water should be poured during the spring and spring seasons, and appropriate watering should be performed in summer and autumn. When planting, it will vigorously spread 2 kg of fine soil and 10 kg of fine soil and spread it to the planting hole. The height of the fennel seedlings above 26 cm began to top-dressing, 15 kg of potassium sulfate and 15 kg of diammonium phosphate were dissolved in advance, and water was applied. After 15 days, drip irrigation allowed 700 kg of decomposed human excrement (pay attention to ventilation to prevent ammonia from being smoked). Sixth, spraying fertilizer in the growth period of bulbs and fennel, every 10 days with Jianzhibao biological fertilizer 500 times spraying one time, even spray three times; with plant power 2003 spray 1 or 2 times; with 50 ml rice vinegar Add 25 grams of potassium dihydrogen phosphate to water 15 kilograms sprayed 3 to 4 times, significantly increased production.
