The fastest planting method of celery planting technique of celery

Celery has been planted in China for a long time, and there have been some records about it since ancient times. Up to now, celery is still a very popular vegetable among consumers. Celery is grown in many parts of our country, it looks very simple, but if you want to grow well, you still need to pay attention to some methods.

The fastest way to grow celery

The main results are as follows: 1. Sowing at the right time. It is generally carried out in the greenhouse from late January to early February, in the sunny bed or plastic arch shed in late March, and raising seedlings in the open field in mid-April. All localities can sow seeds at the right time according to the specific local conditions.

2. Planting. Combine ploughing, ploughing, soil preparation and fertilization. Select strong seedlings, large seedlings, planted from all around, planting depth to bury the rhizome is appropriate. The general row spacing is 20-30 cm. The planting density can be determined flexibly according to the market demand. 5) Fertilizer and water management. When planting, the first water must be watered thoroughly, and the soil should be kept moist after 15 days. After 15 days, the soil should be dry and wet, and the soil should be ploughed, loosened and weeded. In the vigorous growth period about 30 days after planting, the management of big water and large fertilizer should be carried out, such as irrigation once in 5-7 days, topdressing once in 10-15 days, topdressing urea 20 kg in 667m2, or diammonium phosphate 15 kg each time. When entering the high temperature season in June and July, pay attention to maintaining the field capacity to create a wet and cool growth environment for celery. Stop irrigation 7-10 days before harvest.

Celery planting technology

The main results are as follows: 1. After the previous crop harvest, about 5.000kg/667 square meters of mature organic fertilizer was applied, turned 25-30cm deep, and then ploughed and leveled to form a flat bed with a width of 1-1.5m, which was planted in cloudy or cloudy days. The root length of 4-6cm should be left when the seedlings are raised, and the big and small seedlings should be graded and planted. If the planting depth is too deep or too shallow, celery is prone to slow seedling, low survival rate, slow growth after survival and so on. The dry soil should be watered once after planting, but the current should be slow to prevent the seedlings from being washed.

2. The wet planting method which has been tried and popularized in recent years is more simple and convenient. After finishing the bed, the wet planting method is to pour water first, line the border with a rake made according to the width of the row, and plant the celery seedlings in the wet mud across the line according to the plant spacing. Wet planting has the advantages of fast planting, slow seedling and good root, which is better than traditional dry soil planting. Determine the plant spacing and row spacing, depending on the variety, general celery 12cm × 15cm, planting 28000-33000 plants per 667m2, properly close planting; celery large seedlings 20cm × 30cm, medium seedlings 20cm × 25cm, small seedlings 20cm × 20cm, 10-15000 plants per 667m2 to ensure sparse planting, in order to achieve the purpose of high quality and high efficiency.

Field management after celery planting

We should do a good job in field management. In winter, spray new high-fat film, heat preservation and anti-freezing, isolate bacteria, and at the same time press the greenhouse film to avoid air leakage. At noon on a sunny day, uncover the greenhouse film, ventilate and reduce humidity. Before the ridge sealing, the plant was poured with clear water and dung for 3 times, and after the ridge was sealed, the urea solution was drenched once. One month after planting and one week before harvest, Zhuangtuanling was sprayed respectively to make the plant stalks stout, leaves thick, leaves fresh and tender, plants luxuriant and natural taste strong. At the same time, it can improve the ability to resist disasters, reduce the amount of pesticides and fertilizers, and reduce residual toxicity.

Insect pests of celery and its prevention and treatment

1. Soft rot. Prevention and control methods: crop rotation for more than 3 years. Avoid root damage when transplanting, loosening the soil or weeding. Drain water in time after rain; dig out diseased plants in time and disinfect them with lime. Watering is reduced or suspended during the onset of the disease. The following chemicals were sprayed in time: 72% agricultural streptomycin sulfate 3000-4000 times solution, 50% copper succinate wettable powder solution, once every 7-10 days, continuous prevention and treatment for 2-3 times.

2. Virus. Control methods: take measures to control and avoid aphids. Strengthen fertilizer and water management, promote plant growth and improve plant disease resistance. Foliar fertilizer spraying can also improve disease tolerance. At the initial stage of the disease, 1.5% Zhiyanling emulsion was sprayed 1000 times, or 20% virus A wettable powder was sprayed.

The planting of celery must first do a good job of site selection, and then the drainage system needs to be done well. if there is serious water in the planting area, it may affect the growth of celery. Because celery is also vulnerable to insect pests, it is necessary to do a good job in pest prevention and control in the later stage. Only after doing this well, the celery will grow well and the yield will be high.
