How to use greenhouses for winter celery cultivation?

How to use greenhouses for winter celery cultivation? The use of greenhouses for the production of celery and Chinese celery in the winter has a delicate texture, less fiber, and good quality. It is welcomed by the market. The supply period coincides with New Year's Day and the Spring Festival, and the output value is also high; at the same time, it is a greenhouse in early spring. A good mouthwash for fruits and vegetables such as cucumbers. (1) Choose good breeds. Shed celery should be selected from varieties that have strong cold resistance, good quality, high yield, and late bolting. Such as: Kaifeng glass crisp, solid celery, Jinnan real celery No. 1, Chunfeng and other fine varieties of Chinese celery. Western parsley can use Italian winter celery, Utah 52-70, Florida 683, Cornell 619 and other varieties. (2) Sow seedlings. The plantings were harvested in stages from late July to mid-September. The supply period was from November to March of the following year. 1 Preparation of nursery beds. The nursery period coincides with the summer heat season and therefore requires careful management. Seedbed land should be selected for both drainage and irrigation, loose and fertile soil, and well-ventilated plots. Before sowing, the bed soil should be deep tilled and sun-dried, and 3,000 kg/mu of fully-fertilized organic fertilizer should be used as a basal fertilizer in combination with site preparation. The land should be leveled and leveled to make a sorghum with a width of 1, 2 meters. 2 soak germination. Since celery is a cool and cool crop, sowing in low temperature and germination is required during the high temperature season. Soak the seeds with a temperature of 50-55 °C for 20 minutes, and continue to stir to kill the pathogens on the surface of the seeds. Then soak in the cold water for another 24 hours, then dip in the soaking process several times to facilitate water absorption. Then remove the seed and drain the net moisture and wrap it with gauze, place it in the lower part of the freezer of the refrigerator, or hang it in the well 20 to 30 centimeters away from the water surface. Rinse once daily. After about 5 to 7 days, the seeds will be 50% white. You can sow. 3 sowing. When the seedbed is soaked in the bottom water, it is appropriate to sow the planting, sowing the plant shall be uniform, and the cover soil shall be fine so as not to see the seed as the degree. Seeds of 0.5 to 1 kg were planted per acre seedbed. The ratio of seedbeds to planted fields was 1:8 to 10 (Chinese celery) or 1; 15 to 20 (western parsley). 4 Seedling management. The seedling stage of celery mainly focuses on the following aspects: First, shading: The seedbed adopts a rainproof shed (covered with a net and a membrane) to prevent heavy rain from scouring and the operation is also convenient. Before emergence, seedling beds should be covered with straw, grass, water lotus and other cool moisturizing anti-burst attached, and often sprinkle water to keep the bed moist, in order to facilitate the growth of young shoots. After the emergence of the seedlings, the ground cover was removed, and no rain-proof scaffolding beds were required to take a 1-1. The 2m high pergola is covered in shade and covered with bamboo curtains, reed curtains or shade nets. It is necessary to cover the sun without covering the shade, cover the sun without covering the night, and cover with heavy rain. Second, thinning: after emergence and seedling height 2. At 5 cm (about 1 to 2 true leaves) and time seedlings. When the height of the western celery seedlings is 10 cm (3 - 4 leaves), the seedlings can be transplanted and planted once. The seedling distance is 10 cm X 8 cm. Since the seedlings are not seeded, the seedlings should be separated and transplanted when the seedlings are transplanted to facilitate management. Plant beds also need shade to cool and moisturize. Later seeding may not require shading. Third, weeding: the slow growth of celery seedlings, timely removal of weeds, to prevent weeding, can be used after sowing with 50% prometryne wettable powder 100-150 g / acre, or 48% trifluralin EC 150 ~ 175 g/mu, or 48% Diflummet emulsifiable concentrate 200g watered 60 ~ 70 kg evenly on the soil surface, chemical weeding save time and labor, and the effect is better. Fourth, water and fertilizer management: During the entire nursery period, pay attention to watering and keep the soil moist. Watering should be done with little water and it should be done in the morning and evening. Watering in the noontime will cause temperature difference on the surface of the earthworm, resulting in dead seedlings. After the seedlings can be sprayed with 0.3% potassium dihydrogen phosphate and 0.2% urea mixture to promote seedling growth. About 7 days before planting, watering was controlled, and the seedlings were intensively rooted to facilitate the establishment of the seedlings after planting. (3) Site preparation and planting. The greenhouse celery has a long growth period and high yield. It is a fertilizer-consuming and water-consuming crop, and the cultivated plots should be ploughed deep. The Mushi cultivating heap will be 4000-5000 kg of fertilizer and 30 kg of superphosphate. 4 - 6m wide sheds make 2 squats. Chinese celery 4-6 leaves 40 to 60 days of seedling age, Western celery 7 to 8 leaves 60 to 80 days of seedling age, can be planted. Before the planting, the seedbed should be filled with water to make the roots close and easy to survive after transplanting. Select sunny afternoon or cloudy day colonization, planting should be carried out with soil mulching, so that seedlings to reduce damage, most Chinese celery 10 cm square plant spacing, and Western celery plant spacing should be relaxed, generally 20 to 25 cm 50 to 60 The centimeters were planted in rows and plants were planted in order to fully grow and express the inherent quality and flavor. The depth of planting seedlings is not suitable for burying the heart. When planting, it is necessary to use robust seedlings of the same size as possible. Small and thin seedlings should be removed or not planted separately. This is convenient for management. (4) Management after planting. 1 Timely shed insulation. The speed of growth of celery in the range of 1 to 20 °C increases with increasing temperature. It grows poorly above 20 °C, stops growing at 0 °C and freezes at a temperature of 6 °C. The winter celery of greenhouse first colonizes the open space in the greenhouse frame, and it is necessary to timely tarpaulin in late October to early November (coverage time is determined by the minimum average temperature of 13 °C in ten days). The temperature at the initial stage of the shed is still high, and it is not ventilated at sunny noon. The greenhouse temperature can reach 35 °C. Therefore, attention should be paid to ventilation to reduce temperature and humidity. Generally, ventilation should be started when the temperature reaches 20 °C. The maximum temperature should not exceed 25 °C. Otherwise, the plants are susceptible to aging, and the petiole is long and stiff, with many fibers. Affecting the output and quality, the previous management focuses on temperature control, maintaining the shelf temperature at 15 - 25 °C during the day, and not less than 10 °C during the night. After the outside temperature drops to around 6 °C in late November, the shed can be restrained and only slightly ventilated at noon. When there is a cold current, small awnings or non-woven fabrics should be covered at night to prevent cold. After entering December, the temperature dropped drastically, and in the greenhouse, the best multi-layer coverage at night prevented freezing damage, so as to facilitate the growth. 2 Strengthen fertilizer and water management. The temperature at the initial stage of colonization is slightly higher, and the soil evaporates quickly. Generally, the water is poured once every 3 to 4 days to keep the soil moist. After the water is poured twice, the soil is cultivated and cultivated. One month after planting, new roots and new leaves have already occurred in large quantities. At this time, 15-20 kg of nitrogen, phosphorus, and potassium fertilizers can be applied per acre, combined with fertilization and irrigation, to ensure that the roots normally suck in fertilizers to absorb water, and promote the strong growth of the shoots; 20 to 30 days after the follow-up of a quick-acting nitrogen fertilizer, can be applied per acre with water flushing urea 7 . 5 to 10 kg. Within two months after planting, it is the strong growth of celery that must not be deficient in fertilizer or water, otherwise it will delay growth and result in serious reduction of production. In the cold season, the moisture in the shed is not easy to dissipate, and the number of watering and watering should be reduced. To prevent the occurrence of diseases due to excessive humidity. 3 Cultivating and weeding: Within one month after planting, cultivating 2 to 3 times, and combining with cultivator for weeding, stop the cultivator when the underground root group expands in the middle and late period and the above-ground plants have grown up. (4) Spraying hormones: One month before the harvest of celery, spraying gibberellic acid (90% O 2 ) at a concentration of 20 to 30 mg/L for 7 to 10 days for a total of 3 injections, which can significantly promote plant growth and increase yield. Improve quality. (5) Prevent and treat pests in time. The main pests and diseases are: celery root knot nematodes, leaf spot disease, and gray mold. Control methods: 1 root knot nematode: Refer to the “Plant Pest Control in Greenhouse” section of this book. 2 Leaf spot disease: mainly prevention, such as crop rotation, seed soaking in warm water, paying attention to ventilation and dehumidification in the greenhouse, etc. In the early stage of disease, “one smoked” smoke control or 70% mancozeb 600 times liquid, 75% chlorothalonil can be used. Clear 600 times liquid spray. 3 gray mold: refer to the book "Plant Vegetable Pest Control" section. (6) Harvest. When Chinese celery grows to 60 to 70 centimeters, it can start harvesting. According to market needs and mouthwash arrangement, a harvest or multiple harvesting of loquat leaves can be implemented. Generally, the leaves collected from the leaves of the medlar leaves usually contain 1 to 3 leaves per leaf, and it is advisable to leave 1 leaf and 3 leaves in the middle of the leaf, which can be harvested from mid-November and harvested in 25 days or so. The petioles that have been harvested are bundled according to their length and length. In addition, due to the large humidity in the greenhouse, weak light, and easy-to-infect diseases, the thiophanate-methyl or Epimedium 800 times liquid can be used for protection after each loquat leaf. After the first temporal leaf, clear yellow leaves, rotten leaves, and old leaves. Collect water once a day before harvesting. Do not water immediately after each harvest. Since the wound does not heal, watering can easily cause rot. About one week after the harvest, when the wounds healed and when the heart began to grow, it was necessary to strengthen the management of fertilizer and water. Each acre could be topped with 10 kg of urea or 15 kg of nitrogen, phosphorus, and potassium compound fertilizers, and be used with watering to keep it moist. In general, the output of greenhouse celery is 3500 to 5,000 kg/mu in one harvest, and 10,000 kg/mu in many harvests. Western celery is usually erected upright 75 to 100 days after planting, and the heart should be harvested in a timely manner. Otherwise, it is easy to crack and reduce the value of goods. When harvesting, the ground shall be harvested to connect the base of the petiole without dispersal, then the yellow leaves will be removed, the soil will be washed, and the average yield per mu is 5000 to 6,000 kg. If each plant can be packed in a plastic bag, not only can the goods be improved, but also Can play a role in preservation, increase economic efficiency.
