How to prevent celery from bolting early

Celery is very popular in China, but many people can't stand the taste. Like parsley, it is a polarized vegetable. The planting area of celery is very wide in our country, but the phenomenon of early bolting of celery will appear in the process of planting. Early bolting of celery will seriously reduce the yield and affect the planting benefit. And there is no therapeutic value, only prevention, so how can we prevent early bolting of celery? Let's have a look with the editor.

1. Sowing seeds at the right time

The sowing time of celery is very important, and when planting celery in autumn in the protected area, the best sowing time is from early August to early September. The best time for spring sowing is around February. Sowing too early and too late will affect the growth of celery, resulting in poor growth of celery, difficult to develop into a complete celery, leading to the phenomenon of early bolting and damage to planting efficiency. If the seedlings are raised in the greenhouse, then it is necessary to cover the bed with plastic film in advance and sow seeds only when the soil temperature reaches about 10 degrees.

2. Temperature control

Temperature is also one of the main reasons for early bolting of celery. If seedlings are raised in winter, attention should be paid to the heat preservation of seedlings. The temperature should not be lower than 8 degrees, the temperature should be kept at 13 degrees at night, and the temperature should be increased by 2-7 degrees during the day. Plastic film can be covered on the seedbed or arched sheds can be built to improve soil temperature and soil insulation. Then use light to increase the temperature before raising seedlings, and pay attention to heat preservation when the temperature is low at night. If the temperature is uncomfortable, it can easily lead to early bolting of celery and affect the growth of celery.

3. Fertilizer and water management

The growth of any crop is inseparable from fertilizer and water, and celery is no exception. During the growth period of celery, it is necessary to do a good job in fertilizer and water management to prevent discomfort from affecting the growth of celery, leading to early bolting of celery. And the squatting seedling work can not be carried out in the process of celery growth, and the watering frequency can be increased, which can be irrigated with appropriate flood to ensure that the soil is moist. When topdressing, increase the proportion of nitrogen in fertilizer to meet the nutritional needs of celery growth. Adequate water and fertilizer can ensure the healthy growth of celery, promote the absorption of celery nutrition, prevent reproductive growth, and reduce the phenomenon of early bolting.

4. Timely harvest

Timely harvest is the most direct and effective way to prevent early bolting of celery. We can start harvesting before the celery bolting grows. Or harvest leaves, can effectively reduce early bolting, harvest must not be carried out after bolting maturity. The taste of bolted celery will be seriously decreased, affecting the commodity value. Among them, the harvest of overwintering celery is more important, after the temperature gradually rises in spring, overwintering celery and flower bud differentiation begin to bolting around April. Therefore, overwintering celery must be harvested in April to prevent bolting from affecting planting efficiency.

The above is a brief introduction to the prevention methods of early bolting of celery. Early bolting of celery will consume too much nutrients, resulting in too little accumulation of nutrients in the trunk of celery and a decline in quality. The value of the commodity drops, it cannot be listed, and even if it is sold on the market, its reputation will get worse. Therefore, we must do a good job in the prevention of early bolting of celery. That's all for today's introduction. This article is for reference only. Thank you for your reading and support.
