Gidroponics is a plant method in which plants grow with the help of nutrient solutions of minerals dissolved in water, without the soil in which it is replaced inert substrate. It can consist of expanded loy, perlite, vermiculite, coconut fiber, stone cotton, zeolite and others.
the nursery is moved to the inert supports at a distance of about 60 cm from the ground, fixed to the top of the greenhouse and it is watered with a nutrient solution consisting of water and compounds necessary to restore all the necessary elements to normal mineral food.
In greenhouses, tomatoes, zucchini, peppers, eggplants and long strings of salad are supported, which are located at a distance of about one meter.
It is a place where plants are needed for care and harvesting. Carbon dioxide fertilizer that accelerates and multiplies photosynthesis in combination with oxygen and nitrogen in the air, it is amazing and continuous plants throughout the year.
Two cuttings from each seedling, one to the left, the other to the support line. Double cutting
it is produced for twisting with a thread attached to the top of the greenhouse, at a height of 4,5 meters, to hold them.
The upper part of the thread is wrapped in a thread, and with the growth of the plant, the lower part is defoliated, and the fruits appear and they ripen slowly. And as the plant grows, the duck spreads and moves along the hanging thread about 50 cm. And so on, the maximum height they will never exceed the height to which they are connected, and part of the maturation is always the same height, the easiest collection.
Those who into the vein remove the sinus thallium, additional leaves and carry out the calibration of the candles, after removal, fast installation, super-frame products. With this type of cultivation, the amount of water is used for the same production, this is about one tenth in comparison with the cultivation in the soil. The environmental side should not be taken into account, as the use of fertilizers purposefully and in the soil there are no dispersions, there is no use of herbicides.
They do not use insecticides. However, other insects, such as bees and Bumblebees, are found in boxes scattered among the rows that are struggling with them harmful insects. And where they do not come up with other insects, they use bait and traps with the pelvis in the picture.
Otherwise, the intervention of the target brush is carried out with the help of clay-based preparations.
The main control parameters are five:
First, of course, pH. its balance is important to maintain the state of solubility of the elements and to optimize metabolism processes between the roots and the nutrient solution. PH, which differs from the Optimal range, worsens the nutritional status of plants because of the chemical or physiological immobilization of one or more mineral elements.
The concentration of the nutrient solution is controlled by regulating electrical conductivity. Associated with low permeability excessive dilution of the solution, so that the plants are in conditions of low mineral nutrition. Consumption, time and dosing cycles: the control of mineral nutrition is carried out by accurately controlling the flow rate and feeding time a nourishing solution that regulates the exchange of solutions in contact with the roots. With the chemical composition of the solution, the nutritional balance of the plants in relation to different nutrients, the ratio of antagonism.
