Post-emergence management techniques of celery have a crucial impact on its growth and yield. Here are some key management technology takeaways:
1.Maintain the right temperature and humidity: During the emergence of celery, the right temperature and humidity should be maintained to promote its normal growth. In general, the temperature should be kept between 15 -20 during the day and 10 -15 at night. At the same time, the soil should be kept moist to facilitate the growth of seedlings.
2.Timely weeding and soil loosening: After celery emerges, weeding and loosening the soil should be done in time to promote its root growth and retain soil moisture. Weeding can be removed by hand or with tools such as hoes. Loosening can be done with tools such as iron hooks, but care should be taken not to damage the seedlings.
3.Control of water and fertilizer: During the emergence of celery, the application of water and fertilizer should be controlled to avoid the phenomenon of seedling growth or seedling burning. Generally speaking, fertilization can be started about 10 days after the emergence of seedlings, and the amount of fertilizer applied each time should not be too much to avoid burning seedlings. At the same time, the soil should be kept moist to facilitate the seedlings to absorb water and nutrients.
4.Control of pests and diseases: During the emergence of celery, attention should be paid to the prevention and control of pests and diseases, so as not to affect its growth and yield. Common celery pests and diseases include cataplexy, blight, sclerotinia and so on. Different control measures can be taken for different pests and diseases, such as spraying pesticides, biological control, etc.
5.Strengthen field management: During the emergence of celery, field management should be strengthened, problems should be found in time and corresponding measures should be taken. For example, if it is found that the seedlings grow slowly or grow slowly, they can be remedied, such as increasing or decreasing the application of water and fertilizer.
In conclusion, celery post-emergence management techniques have a crucial impact on its growth and yield. The growth and yield of celery can be effectively promoted by maintaining suitable temperature and humidity, timely weeding and loosening of soil, control of water and fertilizer, control of pests and diseases, and strengthening field management.
