Celery, we call it American celery. It can be used for both cold salad and cooking. There are also a few people who grow celery in the countryside today, but because of the slow growth of celery, it will affect the income of planting. Let's talk about the germination and germination technology of celery. Let's learn together.
First, low temperature germination
Celery is a low-temperature crop, so we use low-temperature germination. If the temperature is higher than 25 ° C, the germination of celery will be very slow. Therefore, growers should pay attention to the temperature control.
1, pre-emergence treatment
Before germination, we need to expose and soak the celery seeds. The method is relatively simple, as long as the seeds are exposed to sunlight for 8h-10h, and then soaked in water for 12h-16h. After handling, remove the seeds and put them in a cool place.
2, germination
Low temperature germination is usually carried out in the refrigerator. The specific method is: wrapped in gauze and placed in a refrigerator at 10 ° C - 15 ° C for germination. The time is 3-4 days. After celery with low temperature germination, the germination rate will be greatly improved.
Second, sunscreen moisturizing
The seeds of celery are small and the ability to arch soil is weak, so the covering soil must not be thick, about 0.5cm. Pay attention to sunscreen moisturizing after covering the soil. You can cover it with straw and other things, then pay attention to the water supplement. When the seedlings break out of the ground, the cover can be removed.
Third, emergence management
After the emergence of celery, it is the focus of conservation management. The first is the seedling. When the seedlings of celery grow to 2-3 leaves, the seedling distance should be kept 5cm-7cm. And watering in time to maintain the soil's wetness.
After the celery grows for 1-2 weeks, we can fertilize it. The method of fertilizing is to apply a thin human urine manure, and then apply fertilizer once every 2 weeks.
