Autumn and winter to prevent greenhouse celery hollow
In the autumn and winter greenhouses, celery has more hollow and increased fiber, which is caused by the high temperature and low humidity greenhouse environment. High temperature can accelerate tissue differentiation, and low humidity can not meet the plant's demand for water, so that the plant's pith tissue is decomposed, resulting in hollow celery and increased fiber. In order to avoid this phenomenon, we must do a good job in temperature and humidity management.
In winter, celery is cultivated. People are afraid that watering will cause the soil temperature to drop and affect the growth of celery. In fact, as long as the watering is appropriate, it will not affect the growth of celery. Generally, watering once every 15 days, the amount of water should not be too large, and the small water can be slid. 15 days before the harvest, it should be poured twice. Celery is cool, and should be properly lowered during management, and kept at 15 °C ~ 18 °C.
