How to realize factory cultivation of celery? growing vegetables does not depend on heaven and earth.

The cultivation area of celery is getting larger and larger. NFT cultivation of celery not only solves the obstacles of continuous cropping, soil salinization, destruction of physical and chemical properties, but also greatly increases the yield and quality of celery, shortens the growth period, improves land utilization, and realizes factory and weekly production. The NFT technology of celery is introduced as follows.

1 Construction of facilities

The NFT cultivation of celery should be carried out in protective facilities, and pipes should be laid. First, piling should be made, and the height of the frame should be operated by people standing up, and the pile frame should be neat. The pipe should not be too long, otherwise there will be uneven supply of nutrient solution. Generally speaking, each planting tube is 77 and a half meters long, with a maximum length of no more than 15 meters. The plumbing material is a non-toxic tap pipe, otherwise it will affect the quality of vegetables. In the way of high inlet end and low drainage end, the slope of 8 / 1 000 is more suitable, and the pipeline requires neat and uniform line spacing, which is beneficial to operation and management. The cultivated hole distance is 20 cm, and the electric punch is used to punch the hole.

2 cultivation and management

The concentration and pH of nutrient solution are detected every day, and the concentration is low and mother liquor is added. High concentration, add water. The principle of nutrient solution: small seedling concentration, high seedling concentration, low temperature, high concentration and low temperature. The adjustment is carried out in the evening, and the concentration is relatively high at night and low during the day.

(3) Disease and pest control

Few diseases occurred in celery NFT cultivation, mainly aphids and whitefly, and yellow armyworm board was hung on the 20cm above celery.

4 harvesting and postharvest management

The celery grown in NFT is clean and easy to harvest, as long as the old leaves of celery are removed, live celery is put on the market, and the fresh-keeping period is prolonged. Clean the leaves on the ground after harvest and sterilize the ground with lime every month. After that, bleach is added to the nutrient pool and recycled for one day to disinfect and sterilize the pipes. Then the pipe is dried for a day or two to prepare for the next batch.

The root environment of celery has been greatly improved by using NFT cultivation technology, which makes the crop growth from difficult to control to easy to control, easy to mechanize and automatic operation. The superior environment makes the photosynthetic rate high and the respiratory intensity low, so celery has the advantages of fast growth, high yield, good quality and greatly increased output, which is a good cultivation model for urban agriculture.
