Hydroponic vegetables planting methods: pre-preparation, root treatment, hydroponic methods.

1, pre-preparation: vegetables in the process of hydroponics, water as a substrate, so we should choose a plastic box that can hold water as a hydroponics vessel, and to clean and disinfect it, so as not to residual hazardous substances, but also to the plastic box into a piece of pontoon, easy to fix the vegetables, so as not to soak the whole plant in the water and rot.

2, root treatment: hydroponics vegetables before the need for hydroponics to take out the vegetables, clean the root system with water, and then use sterilized scissors, the roots of the withered roots, rotten roots cut, and then use potassium permanganate diluted solution of disinfection by immersion for 30 minutes, and finally rinse the agent with water after hydroponics.

3, hydroponics method: the process of hydroponics, to fill the plastic box with water, and then insert the treated vegetables into the water surface of the floating board, to ensure that the root system in contact with water, so that the leaves are in the floating board above the position can be, pay attention to hydroponics during the period of the regular addition of nutrient solution to the box, and once a week to replace the water, to keep the water quality clean.

Advantages and disadvantages of hydroponic vegetables

High yield: hydroponic vegetables in the yield than the traditional soil cultivation or substrate cultivation of several times or even a dozen times higher. Good quality: Because the nutrient solution is used for cultivation, its nutritional supply is balanced, so the taste is better, better quality. Safe and tasty: those cultivated with nutrient solution can reach Grade A green vegetables, and those cultivated with organic fertilizer can reach Grade AA level.

Drawbacks: the general hydroponic vegetables are lighter in color, the stalks are longer and look uninspiring, hydroponics and light can not be carried out at the same time, strong light will make the water temperature increase, either you have to reduce the light, which makes the plant lack of photosynthesis.
