Banqiao white celery, also known as Qingqin, Fragrant celery, and mildew, is a local seed of Yuhuatai District. Its flavor, fragrance, good quality, high yield, strong disease resistance, can be cultivated in all seasons. Plants are semi-vertical, plant height 71.7 cm, stems green, 1 cm thick, stems prone to adventitious roots. Holding the stem, solid, 25-30 grams per plant. The growth period is 40-180 days and the mu yield can reach 3,000 kg. On the growth, green stems were used for asexual reproduction, and axillary buds were used to germinate into new plants. The new leaves are softened with earth white or light yellow, and are the main edible parts. Cultivation of white celery is actually a dry cultivation of cress. Green earthless celery can be used as green celery, fragrant celery, and mildew celery by the time of market; earth celery is white celery and tender stems are white. Its cultivation techniques are as follows: 1. Soil fertility selection The fertile deep night tide soil, Mushi human feces 2500 kg, organic-inorganic compound fertilizer 120-150 kg. Insulation is low, the ditch is high, and the height difference is 30-40 cm, which is convenient for earth-cultivation and water conservation. Second, rows of vines in late September - early October row of vines (mother strain), the first year of April the following year in mid-to late June listed as incense celery. In order to mention the city in the morning, the row of vines is earliest in early September. After arranging the vines, cover them with plastic sheds and cover the surface of the mulching film. In early June and late July, rows of vines are sold, and in early July and October, they are listed as green celery. When rowing vines, the oysters will be flattened first, and the ditch will be opened. The ditch will be 20 centimeters long, open one ditch, one ditch, one ditch, and finally watered. The sorghum noodles were covered with smashed straw. In the summer, high temperatures can be used to cover the temperature drop with a black shade net. The height of the arch shed is 1.2-1.5 meters. When the shoot length grows to 14-17 centimeters, the stalks are planted with a spacing of 1720 centimeters and 3-4 strains per hole. Third, the field management of live trees once poured Miao Fei, according to the soil dry and wet conditions, watering every other day. Irrigate at 10:00 am, because celery likes cool, watering at this time, can reduce the temperature and promote plant growth. During the growth period, the fertilizer was top dressing 2-3 times, and the fertilizer was mainly organic fertilizer. When the soil is dry, both water and fertilizer are present. Coverage film time is determined by the lower limit of the average temperature of 13 degrees in ten days. The shed covers the earliest at the end of October. Fourth, soil softening This method can improve the quality of celery and increase plant height. The winter cultivated green parsley is softened to white celery by soil. In November in Nanjing, when the seedling height was 23-25 ​​cm, the manure was poured once, then the ternary compound fertilizer was also applied to the ditches, poured 1-2 times of concentrated manure water, plough frozen hoe, and knocked the soil. Hey, spare. When cultivating soil, separate celery with two thin strips of wood (14-17 cm in width) and cultivate the soil between rows. Each time the soil is cultivated to 10-13 cm thick, a total of 3 soils are cultured. When the temperature is high, the interval can be shortened. 5. After the end of harvesting, the seedlings can be harvested and harvested 22 to 5 centimeters long. When harvesting, the soil is first opened with a rake, and then the white celery is picked up or harvested with a hoe, then rinsed in clean water and bound for listing. Harvest time is from the beginning of November to the fourth of April, with the best quality before and after the Spring Festival. Sixth, the mother vine management if found rotten, should be promptly removed, in the diseased plants with lime powder disinfection, or carbendazim WP 1:500 times sprayed plants.
