According to the reality of long growth cycle, germination and slow growth of winter celery, combined with years of planting experience, we planted both vegetable and celery seeds at the same time, and harvested vegetables and celery in batches through later management. This can not only make full use of land resources, but also achieve double planting benefits, so today Xiaobian talks about celery and vegetable cultivation techniques.
First, the variety selection
Celery uses stable, high-yield, high-yield and high-quality varieties in the field, such as SG yellow celery, American white celery, etc., the amount of land per acre is 400g; the vegetable selection is stable in the field, disease-resistant and cold-resistant, fast growth, high yield High-quality varieties, such as Yuehua, Dongfang 18, etc., use 350g per mu.
Second, soil preparation and fertilization
Winter celery grows longer, and with the vegetables, so the growth requires a large amount of fertilizer, per mu of fully fermented organic fertilizer 2000 ~ 2500kg, ternary compound fertilizer (NPK ≥ 45%) 50kg 1kg of boron fertilizer is used as base fertilizer. After the planting area is ploughed and smoothed, the width of the hoe is 140-160cm (as far as possible is not more than 160cm), which is beneficial to the field farming operations such as harvesting and artificial weeding.
Third, sowing
1. Sowing in the middle and late November, after pouring the water to the bottom of the bowl, spread the vegetables evenly, and then spread the celery.
2. Before planting, the water is sprayed through the sprinkler irrigation facility.
Fourth, field management
1. The vegetables will emerge 4-5 days after sowing, and the celery will take 10-13 days.
2. After emergence of celery and vegetables, spray 75% of carbendazim 3000-5000 times solution and 16000 IU/mg of Bacillus thuringiensis 500-750 times solution every 15 days to prevent seedling pests and diseases.
3, emergence of 45 days, the vegetable grows to five leaves and one heart to six leaves and one heart, celery one leaf and one heart period, according to market conditions, harvest vegetables.
4. When harvesting, adopt the “carpet type†method to harvest the vegetables. No matter the size of the vegetables, all the harvested vegetables are sold according to the size.
5. After the harvest of the vegetables, the celery is artificially weeded and interplanted, the seedling distance is kept 2~3cm, and then 10~15kg of urea is applied per mu. When the celery grows to 3 to 4 true leaves, the second weeding is carried out. After weeding, 10 to 15 kg of urea is applied per mu, and the broad-spectrum fungicide is sprayed once every other day, and then according to the field growth and the temperature change according to the routine. management.
V. Pest Control
There are few pests and diseases of winter celery, and the leaf miner should be prevented at the seedling stage. In the early stage of the disease, 75% of the anti-wet powder can be sprayed with 25% to 3000 times.
Use 70% mancozeb WP 600 times solution, 50% carbendazim WP 600-800 times solution, 687.5g/L silver phlegm suspension, 25% amishida to prevent spot blotch, soft Rot.
Before the onset or early onset of celery soft rot, 72% agricultural streptomycin WP, 95% CT bactericide water (copper acetate) 500 times solution, 14% lycopene copper solution 350 times solution were used for prevention and treatment.
Sixth, timely harvest
Winter celery is generally harvested at 10 in the morning, washed with well water 2-3 hours before the sale and then loaded.
