Essentials of cultivation techniques of spring coriander

1. From April 5th to 10th, soak the seeds in clean water for one day and night, and then remove the controlled clean water. It is more suitable to be semi-humid and dry. When germinating, the seeds should be put into plastic pots, and the pots should not be covered, so as to facilitate full ventilation. Put it in the indoor shade (room temperature 20 ° C) during germination at least twice a day, otherwise it will be easy to dry. In this way, after 7-10 days, the buds will be released.

Drought resistance, thermal insulation and frost protection, soil layer compaction, suffocation and isolation of disease and insect sources, increase the emergence rate.

3. Agricultural film management When the temperature exceeds 15 ° C and the light intensity is high, it will be opened at about 8 am, and then the agricultural film will be put on at 3 pm. Prevent roasted seeds roasted seedlings.

4. Fertilizer and water management. The temperature in the season of watering coriander production is low. If the watering is too heavy, it will also reduce the temperature and affect the plant growth. In principle, do not drown and do not water.
