The main cultivation techniques of celery cultivation

First, sowing nursery. Celery can be planted and transplanted, but also live, the former mostly. Our region is dominated by autumn sowing. The sowing date is from June to August. Seedlings use shade nets to cover shade and cool down. Winter sowing (October) and spring sowing (February-February) are also feasible. Seed sowing in the high-temperature period from June to August should be soaked with germination. 40-50 days after sowing can be planted.

Second, rational dense planting. Celery multi-line hole planting. Such as local celery suitable for dense planting. Generally, the distance between the points is 16 centimeters square, 3 to 4 plants per hole, and the height of the western celery plant is generally 2 lines of 60 cm wide (including the ditch). Plant spacing 25-30 cm. Mu planting 4000-5000 strains.

Third, fertilizer and water management. The celery needs a large amount of fertilizer. In addition to applying base fertilizer, it is also necessary to apply fertilizer topdressing. General planting survival after every 4 to 5 days top dressing 1, first applied thin human fecal urine, the dilution concentration of about 10%, to the middle and late growth period gradually increased to 30% to 40%, and appropriate increase in phosphorus, potassium fertilizer. The celery needs a large amount of water and its roots are shallow. Autumn sowing of celery seedlings and the early growth period is at a high temperature season, the need to do a good job of water supply in vegetable fields. Ditch irrigation should be conducted during high temperature and drought to reduce the occurrence of leaf spot disease. The water supply during the seedling stage can be combined with fertilization, irrigating the manure and keeping the soil moist.

Fourth, weeding and weeding. In the seedling stage, early stage and middle stage of celery growth, there are large gaps between rows, and we often need to work in rows and weeds. The roots of the transplanted celery were distributed in the top soil layer. The cultivator should be shallow and not deep enough to achieve the purpose of weeding.

Fifth, pest control. To aphid and spot blight, disease and other hazards. In the prevention and control of agricultural measures and drug control methods should be comprehensively adopted. Disease control can use 65% zein zinc wettable powder 500 times or 75% chlorothalonil 500 to 800 times liquid. Prevention of aphids should be used once again net, big hero and other pollution-free pesticides.
