In recent years, the cold shed tomato-tomato-celery three-cultivation continuous cropping cultivation technology promoted in Angezhuang Town of Yinan County has achieved great economic benefits after several years of cultivation practices. In 2008, each greenhouse (net area 0.6 ~ 0.7 mu) The average economic benefit is over 12,000 yuan, up to 16,000 yuan. The main technical points of this planting mode are described as follows: One, winter and spring tomato 1. Suitable for variety. The United States, No. 4 and New Secret. 2. Nursery time. From late November to early December, seedlings are planted and planted in mid-February. 3. Fertilization and soil preparation. Mushi organic fertilizer 5000 ~ 8000 kg, the United States 30 kg of diammonium, potassium sulfate 20 kg, 2 kg of trace fertilizer, deep-turning the land after fertilization 30 cm, after making a level 10 cm high stilts, width 100 cm wide, covering Plastic film, two rows per plant, spacing 23 cm. 4. Planting time. Planting in mid-February should be carried out in sunny weather with an acre density of around 5000. 5. Field management. After the planting, the temperature should be kept high, and the grass cover should be covered early. The greenhouse temperature should be between 30°C and 32°C during the day and 18°C~20°C during the night. After 7 days of planting, the plants were watered once, and after the heart began to grow, the temperature was appropriately lowered to increase the temperature difference between day and night. The grass cover had to be released early and the seedlings were grown vigorously to avoid seedlings. When more than 50% of the plants bloom, timely preservation, promote fruit. When the diameter of the first ear fruit reached 2 cm, the fertilizer was timely watered, and 10 kg of urea was topdressed. The second time after the fruit was set, the top dressing was watered, and 15 mu of urea was topdressed. At the same time, attention was paid to the prevention and control of pests and diseases. 6. Harvest timely. The harvest began in mid-April of the second year and was pulled in mid-May. Second, the summer tomato 1. Suitable for variety. 1857, warm beauty. 2. Nursery time. Sowing in early May, planting in late June, seedling age about 55 days. 3. Fertilization and soil preparation. Mushi organic fertilizer 3000 ~ 5000 kg, the United States 25 kg of ammonium diammonium, potassium sulfate 15 kg, 2 kg of trace fertilizer, deep-turning the land after fertilization 30 cm, made after the leveling 10 cm high stilts, width 100 cm wide, covering Plastic film, two rows per plant, spacing 25 cm. 4. Planting time. Planting in late June, about 4500 acres per mu. 5. Management technology. After the planting, it is in high temperature weather. Open the upper and lower vents on sunny days. Use shade nets for shade at room temperature of 30°C, and lay 10 cm thick straw on the furrows to reduce the ground temperature. Close the vent on rainy days to prevent rain from entering the room. The daytime temperature is maintained at 25°C to 30°C, nighttime at 16°C to 20°C, and the humidity is controlled at 50% to 65%. Spray with 30-40 mg/kg Tomato Spirit Water solution to keep the stigma moist and increase the fruit setting rate. In order to increase the fruit rate, the first panicle leaves 3 to 4 fruit, and the second and third panicles leave 4 to 5 fruits. The excess, especially the first and the peripheral florets and local dense florets are removed. 6. Harvest timely. Harvesting began in late August and was pulled in early September. Three, autumn and winter wolfberry celery 1. Suitable for variety. Ventura celery. 2. Sowing time. In mid-July, planting seedlings, planting in mid-September, to adopt flat-cultivation cultivation. 3. Fertilization and soil preparation. Spread 5000 to 8,000 kilograms of organic fertilizer, 20 grams of diammonium phosphate or 100 grams of superphosphate, and 20 grams of urea per acre. After the deep plowing, the plutonium was made of 1 meter wide and the length was close to the span of the greenhouse. 1 to 2 days before planting, seedlings were sprayed. 4. Planting time. Planted in mid-September, when the seedlings were planted, dig up the celery seedlings with a spatula root, shake off the soil, do not cut the roots, do not cut the leaves, eliminate diseased and harmful seedlings and weak seedlings, and separate the size seedlings for separate planting. 1 meter wide planting 6 rows, single plant, 8 cm spacing, 50,000 seedlings. The roots of the stretch are planted in the ditch. The depth of planting is based on the length of the roots of the seedlings. Do not bury it in the heart and leaves, and if it is too deep or shallow, it is not good. 5. Management technology. Due to the high temperature, adequate light, and large soil evaporation during this period, on the basis of pouring enough water for planting, two consecutive days after planting, two more waters were continuously fed to promote the occurrence of new roots and to ensure soil protection. After the rain and after irrigation, loosen soil promptly to promote root development and prevent leggy growth. 6. Harvest timely. Celery harvesting is usually from mid-November to the end of January next year. It is listed on the market in batches. The celery must be harvested in a timely manner. If the pods are harvested too early, the maximum yield cannot be achieved. The nutrients in the petiole will be harvested later and transferred to the roots, which will loosen the texture of the petiole and lead to hollows, thus reducing the quality and yield.
