NFT vertical farming

2021-05-17

The NFT cultivation of lettuce requires that it be carried out under the protective facilities, that pipes be set up, and that in the process of carrying out the laying of factory-based pipes, horizontal piling frames should be carried out at both ends and in the middle of the pipe, and that the height should be raised to make it easier for people to stand and operate, requiring the piles to be neatly leveled. Pipes should not be too long, otherwise there will be uneven supply of nutrient fluids leading to poor end vegetable growth and untidy phenomenon, generally 7.5 m long per pipe, the longest should not exceed 15 m, the choice of pipe material should also be non-toxic materials made of water pipes, otherwise it will affect the quality of vegetables due to chemical pollution residues.

Laying pipe system to the water intake slightly higher, drainage end slightly lower landslide mode as good, generally to slope 8/1 000 more appropriate, laid pipe requirements neat and consistent, uniform leading, conducive to the management of production operations, cultivated hole distance according to 20 cm distance for punching, punching can choose the caliber of 5 cm electric puncher for efficient production. When arranging the pipes, make it neat, in order to facilitate the ventilation of vegetables, and the horizontal height of the feed tube slightly higher than conducive to the return circulation of nutrient fluid. The size of the nutrition tank according to the cultivation area, the general circulation of nutrient liquid does not exceed 50% of the total amount is appropriate, the use of pump power to make nutrition to make it cycle.
