Early harvest of celery to prevent seizures is the key


First, the scientific selection of species: the use of strong winter, through the vernalization stage requires strict conditions of the species, but also can choose to grow vigorously nutritious varieties.

Second, the use of new species: new, full-grown seeds than the aged seeds grow into a strong plant, the phenomenon of early convulsions lighter. The use of celery seeds harvested in spring and summer harvest is weak, and the phenomenon of early convulsions is severe. However, using autumn plants and seed collected in the following year, the winter is strong and the convulsions in advance are lighter. When collecting seeds, they should strictly abide by the technical requirements of agronomic practices and prevent the use of pre-existing bolting plants to keep seeding, otherwise it will greatly reduce the winter nature of the varieties, resulting in degradation of quality and aggravating the occurrence of pre-convulsions.

Third, to prevent low temperature: winter and spring seedling period, appropriate sowing, pay attention to insulation, avoid seedlings at a low temperature below 8 °C to 10 °C, night temperature should be above 8 °C to 12 °C, daytime temperature 15 °C to 20 °C, Prevent seedlings from passing vernalization.

Fourth, to strengthen management: after planting to strengthen fertilizer management, timely control of pests and diseases, ensure its normal growth and development, prevent drought, less fertilizer, seedlings, promote vegetative growth, inhibit reproductive growth.

V. Gibberellin: Under the premise of strengthening management, gibberellic acid is sprayed once every 7 to 10 days for a period of 7 to 10 days (9,200). Spraying 2 to 3 times can promote Nutrient growth, slowing premature convulsions.

6. Timely harvesting: harvesting before the buds have not yet grown, or using the eucalyptus leaf harvesting method, can reduce the hazards of early bolting, and must not be harvested when the bolting strain is old.
