Industrialized cultivation technology for celery: growing vegetables without depending on weather or soil
The celery cultivation area is getting larger and larger. NFT cultivation of celery not only solves continuous cropping obstacles, soil salinization and the destruction of physical and chemical properties, but also greatly increases celery yield and quality, shortens the growing period, improves land utilization, and achieves industrialized, year-round production. The NFT technology for celery is introduced below.
1 Facility construction
NFT cultivation of celery must be carried out in protected facilities and requires pipe laying. First, drive piles to build frames; the frame height should be suitable for people to stand and work, and the pile frames should be level and neat. Pipes should not be too long, otherwise the nutrient solution supply will be uneven. Generally, each growing pipe is best at 7.5 meters, and no more than 15 meters at most. The pipe material is non-toxic tap water pipe, otherwise the vegetable quality will be affected. The pipes should be higher at the inlet end and lower at the drainage end, generally with a slope of 8/1,000 being more suitable. The pipes are required to be neat with uniform row spacing, which is beneficial to operation and management. The planting hole spacing is 20 cm, and an electric hole puncher is used to make the holes.
2 Cultivation management
The nutrient solution concentration and pH are tested every day. If the concentration is low, add mother liquor. If the concentration is high, add water. The principles of the nutrient solution: small seedlings, low concentration; large seedlings, high concentration; low temperature, high concentration; high temperature, low concentration. Adjust in the evening; the concentration is relatively high at night and lower during the day.
3 Pest and disease control
Diseases rarely occur in NFT cultivation of celery. The main pests are aphids and whiteflies. Hang yellow sticky insect traps 20 cm above the celery to trap and kill them.
4 Harvesting and post-harvest management
Celery grown by NFT is clean and easy to harvest. Just remove the old leaves of the celery, and the live celery can be marketed with an extended fresh-keeping period. After harvesting, clean up the leaves on the ground and disinfect and sterilize the ground with lime every month. After that, add bleach to the nutrient solution tank and circulate for one day to disinfect and sterilize the pipes. Then let the pipes dry and sun for one or two days to prepare for the next batch.
Using NFT cultivation technology greatly improves the root environment of celery, enabling crop growth to move from difficult-to-control to easy-to-control and easy-to-mechanize and automate. The superior environment results in a high photosynthetic rate and low respiration intensity, so celery grows fast, has high yield, good quality, and greatly increased output. It is a very good cultivation model for urban agriculture.
