Growth stimulants

Stimulators of plant growth

Plant balance management is something that can be done agronomically: if we lower the nutrient solution concentration, there is vegetative development, and raise - generative development. This is something that an agronomist can do without stimulants. However, if it is not possible to set the desired temperature in the greenhouse due to external factors, it is the growth stimulators (regulators) that can direct the plant towards vegetation or generative development.

Exudates of the root system and growth promoters are substances of the same nature. Growth stimulators for growing plants on hydroponics are best used in the form of non-root crops, because when their concentration in the root zone is exceeded, it can have a reverse effect, that is, depressant. It should be borne in mind that leafy feedings in the greenhouse are minimized. At some plants, when cultivating tomatoes, try not to do any treatments on the sheet at all. The Dutch do not aspire to handle everything, they minimize the amount of sheet treatments, because they have a very high cost of labor. They have about 19 euros worth of work. And if a person makes a treatment in a greenhouse, then there is generally a price overstated. Therefore, entomophages are used to protect plants, which themselves run out and work. Also, processing is done by third-party workers from other organizations with whom they have entered into an agreement on plant protection.

Any stimulant with an increase in its concentration after reaching the saturation point has herbicidal effect on plants. The root of any plant allocates exudates - root isolates. If you take the exudates, put them in a Petri dish and soak seeds in them, then in small concentrations they will be stimulants of germination, and in very large ones - the seeds will cease to germinate. Allelopathy works on this way - there are plants that do not allow other plants to grow around themselves.

The task of an expert does not reach the point of saturation with stimulants and micro elements, but as close as possible to it. Only calculations and observations of plants allow you to select the necessary concentrations of nutrients. To date, there are no devices that would keep this maximum permissible concentration. You can also reduce the proportion of exudates, making it very easy, doing a small amount of washing. Exudates are water-soluble and go into drainage, where they break down when it is cleaned. Your task is to keep the exudates and the organic matter of the root zone in such a ratio so that it always stimulates the crop.

A lot of scientific dissertations were written on the topic of humic acids. For example, they write: "By applying humates in the Tambov and Tver regions, we will receive an increase in grain yield by 10% and 40% respectively." The effectiveness of the use of humates depends on the composition of the soil on which they are used. In the Tambov region, chernozemic soils, that are, soils with high content of water-soluble organic substances. In a small dose, they are stimulants for the development of the root system, and in an even greater dose, they are inhibitors. Exudates are measured in milligrams of an organic substance of water-soluble form per liter of nutrient solution. If you reoxidise the organic matter from drainage, you can continually stimulate the plants. The use of hydrogen peroxide in order to stimulate plants is based on this principle. Hydrogen peroxide disintegrates into an active form of oxygen and water. Free oxygen well oxidizes everything, including root extracts, which leads to a decrease in their concentration, which contributes to the growth of plants. Hydrogen peroxide is not a direct stimulant, but at the expense of reducing the amount of organic matter from the maximum level, by only a few percent, accelerates the growth of the root system. There is a simple oxidation of the root isolates of a water-soluble form. This does not include the oxidation of water-insoluble compounds.

Any organic stimulants and amino acids should be used either at the beginning or after washing. It must be taken into account that after the introduction of stimulants you must stop drainage in order to maximally hold the stimulator in the root zone, then the plants will absorb as much as possible. Then you need to do the next rinse to wash out excess and leave only the effect of the stimulant. If you follow this pattern of application, then any stimulant will give maximum effect with its root application.
