Celery cultivation techniques
Soil cultivation: Celery celery grows for a long period of time. It is 5-7 days before planting and cultivating and drying in the sun. Mushi fertilizer is 3000-4000 kg of superphosphate 30-35 kg and ammonium sulfate is 15-20 kg as base fertilizer. After turning to the ground, the width of the plant is 1.3 meters wide (even the ditch), and the depth of the ditch is 15 centimeters. Each line is planted with 4 rows, 25-30 centimeters of plant spacing, and 6800-8200 plantlets. Choose windless cloudy or noon colonization. Before seedlings, 1-2 small seedbeds should be soaked with water to make them easy to survive. The depth of planting is not suitable for burying growth points. Immediately after planting, water was irrigated and boiled water once or twice a day to promote the growth of seedlings. After 2 weeks, bubbling once every 5-6 days. If there is dark and no rain on the planting time, it should be filled with water and then turned to the ground, or it should be planted after irrigating. Sowing seedlings: Celery celery is cool and the growth temperature is 15-25°C. The quality is lower than 27°C, and the organization is coarse and old. It is less than 10°C for 7-10 days, which is easy to twitch and blossom. To select shady, easy irrigation and drainage, fertile soil plots as seedbeds, parallel scaffolding, shading with straw or nylon shading nets, cool down against rainstorms, and promote seedling growth. Before sowing, the seeds are first soaked in cold water for 25-35 hours, so that after absorbing water, they are placed in the refrigerator to maintain the germination at the temperature of 8-10°C and washed twice daily with fresh water until more than 80% of the seeds are exposed. Sow in the seedbed, sowing fine soil after sowing, in order to cover no seeds for the degree, and then covered with straw, full of water. About 5-7 days after the emergence of rice seedlings, remove the rice straw, and then boil water every day to keep the soil moist. Implantation: Celery celery is grown on a single plant, and it grows slowly for about 60 days at seedling stage. In order to make full use of the land and to facilitate centralized management, it is necessary to pass a false planting (unlike local celery) and cultivate strong seedlings. When the seedlings were 2-3 true leaves, they were planted, and the seedlings were batched and planted according to the size of the seedlings. The growth was uniform, the density was 5-6 cm square, and the seedlings grew to 8 leaves, and then the field was planted. Fertilizer management: Celery celery needs a large amount of fertilizer, and it takes about 120 days for growth after planting. It grows slowly in the first half (2/3) and grows faster in the later period (1/3). Therefore, management should be strengthened according to its growth habits. Summer sowing, often due to high temperature and drought after planting, easily inhibit the seedlings turn green, and will lead to childbirth, affecting growth. Therefore, after planting for half a month, apply a thin fertilizer and water every 5-7 days, and keep the soil moist. After 7-9 weeks, the plants grow fastest. At this time, the maximum amount of fertilizer is needed, and they are re-used every other week. Once urea fertilizer 10-15 kg, a total of 2-3 times. The growth of plants in the middle and early stages of growth is slow, and the combination of cultivating and weeding should be used in time to remove lateral buds and reduce nutrient consumption.
