How to carry out blanching cultivation of celery to increase yield and income?
Using the blanching method to cultivate celery can reduce the cellulose content, cause the chlorophyll in the leaf stalks to break down and form lutein, and reduce the secretion of oil glands, thereby improving its edible value and promoting increased yield and income.
The leaf stalks of blanched celery are tender and crisp in texture. At the same time, earthing up also has a cold-protection effect, allowing the harvest period to be appropriately delayed and increasing celery yield. Seedling raising, planting, and field management are roughly the same as for autumn celery. The only difference is that trench planting should be used at planting time, with wider row spacing, which both promotes the growth of individual plants and helps tap the group's yield potential. After planting, spray with New High Lipid Film to improve celery immunity and protect the healthy and robust growth of celery.
The key to blanching cultivation of celery is that the timing of earthing up must be appropriate. Generally, when the monthly average temperature drops to about 10°C and the plant height is about 25 cm, earthing up begins. Because no watering is done after earthing up, before earthing up you should water heavily 3 times in succession to meet the plant's water needs for vigorous growth after earthing up. To avoid plant rot caused by dew on the leaf surface, choose a sunny afternoon when there is no water on the leaf surface to carry out earthing up. The soil used should be fine and crumbly, without clods or impurities, and manure fertilizer must not be mixed in, so as to avoid causing rot. Earth up once every 2-3 days, generally 4-5 times in total. The thickness of each earthing up should be such that it does not cover the heart leaves. The final total thickness of the earthing up is 17-20 cm.
