Planting vegetables by hydroponic method

Hydroponics is a method of growing clean vegetables without using soil very suitable for people in the city. Families can grow their own crops directly into the nutrient solution to ensure food safety for the family.

Vegetables are grown according to hydroponic techniques

The process of growing hydroponic vegetables is quite simple

The application of hydroponic technology for the production of safe vegetables is a system of growing plants in a solution that is researched and completed by the Asian Bean Bean Development Center by Dr. Hideo Imai and David Midmore. Planting vegetables by hydroponic method does not have to adjust the pH due to the stabilization of acid buffer, no aeration and continuous flow of water.

By this technique, vegetable plants are provided with necessary nutrients, isolated from pests, fresh feces, polluted water, avoiding toxins. The model of growing hydroponic vegetables is favored by many consumers, because vegetables are completely clean and safe . Leafy vegetables are suitable for hydroponic environments: lettuce, vegetables, basil, spinach.

Conditions for growing hydroponic vegetables

• Take advantage of the terrace, balcony or front yard. Light for photosynthetic plants at least 5-6 hours in a day.
• It is necessary to avoid rain water so that nutrient solution is not diluted, can make white plastic roof.
• It is necessary to spray water 2-3 times at a sunny afternoon for leafy vegetables.
• Plants should not be blocked from choking: Never let the roots completely submerge the roots, leaving half of the roots on the solution.

The technique of planting hydroponic plants and vegetables is quite simple

Planting tools

We prepare materials to choose a foam box with a length of 40cm - 50cm, 15cm high, black nylon lined box, plastic Gabion with a diameter of 5cm, a bottom of 2.9cm, a height of 7.3cm, a substrate (rice husk) and other nutrients can be sold on the market.

In addition, it is possible to take advantage of available household tools such as pots, pots, plastic pots, baskets, rectangular plastic trays, clay pots, earthenware, with diameter from 20cm, height of 15cm or more and have Airtight lid. There should be more water sprayers to provide moisture for the body, leafy vegetables when grown.

Tools in cultivation techniques of hydroponic plants and vegetables are not too complicated and sophisticated

The steps of hydroponic vegetables

Put the hydroponic bin directly on the cement floor, balcony, yard . where the sun is shining, make a net to protect insects, the foam box must be lined with black nylon to the bottom of the box, black cans work Using the solution and creating a favorable environment for root growth, drill holes into boxes of the same diameter as the mouth in the plastic, the distance of the holes to the density of the plant.

For example: Broccoli, lettuce, amaranth, white mustard drill 12 holes; water spinach, basil, sweet vegetables drilled 20 holes. Put plastic mesh on the bottom of the basket to prevent rice husk from falling into the nutrient solution, stuff rice husk into the gabion, and put the rice husk into the foam box, arrange it to avoid pouring the rice husk out (attention should not be compressed) hand).

Mix the hydroponic solution

There are many recipes for mixing hydroponic solutions, so that a reliable hydroponic formula is blended, we can contact the Phu Tho Plant Breeding Center. Each nutrient bag is used for 12 foam boxes. To share all of us with the mother solution: Put the nutritional powder bag into 6 liters of plain water, then dissolve it all, then put into each foam box 0.5 liter of mother solution and up to the water level for 12 liters of water / box Styrofoam and stirring are a solution of growing vegetables. Before sowing, it is necessary to moisten the substrate to ensure the maintenance of moisture for the seeds. After sowing 7-12 days depending on the crop, when the plant has 2 cotyledons, then transplant it into the basket, it is already packed with the rice husk, then put it into a foam box, the water level in the foam box is flooded with 1/3 plastic basket for 3-4 days. Place on a perforated tray for each type of vegetable.

Attention should be paid to water and light in hydroponic plant and vegetable techniques

Drills

Depending on the type of vegetable that can be spotted. After sowing, place the lid on it, avoiding the grain being disturbed, spraying an additional amount of water on the seed.

Take care of

In the care of vegetables, we must regularly check boxes of vegetables to avoid leaking nutrient solution; need to add clean water until harvest for once-harvested vegetables such as choysum, broccoli . if it is water spinach or aromatic vegetables . it is a vegetable that is harvested many times on the tree to supplement nutrition with 30% of the mother's nutrient solution initially after each harvest; daily monitoring if there are worms, captured by mechanical methods; supplementing and replacing bad and poor trees, dead trees, changing locations for light and nutritious vegetables; cut off the original leaves, yellow leaves, pruned branches, clean the box after each harvest for the crop (water spinach, basil); Summer should be covered with black mesh from 10 to 16 hours.
