Description

The invention relates to agriculture, and in particular to preparations for accelerating plant growth.

Known root stimulant containing an aqueous solution of IMC in a concentration of 0.5 mg / l to accelerate the growth of currant roots (RU 2039427, A 01 H 4/00, 1995).

A root formation stimulator is also known, containing a sterile aqueous solution of IMA at a concentration of 3 mg / L for soaking cuttings of fruit crops for 5 days (RU 2060646, A 01 H 4/00, 1996).

A disadvantage of the known stimulants is the need for long-term processing of the material for a day or more to obtain the necessary duration of exposure to the IMC on the plant. For each plant, it is necessary to select their own soaking modes (duration of exposure to IMC), which greatly complicates the process of growing plants from cuttings. In addition, plants treated with known stimulants have insufficient survival rate and growth rate.

The objective of the patented invention is the creation of a root formation stimulator of prolonged action, which allows to increase root formation and significantly reduce the time for soaking (preliminary exposure of IMC to the cuttings) before planting them in the ground, as well as increasing the survival and growth of cuttings and expanding the variety of plants on which the stimulator acts effectively.

This problem is achieved in that the root formation stimulator containing indolyl-butyric acid additionally contains charcoal in the following ratio of components, wt.%:

indolyl butyric acid 0.4-0.8 charcoal 99.2-99.6

The most effective ratio is: IMC - 0.52 wt.%, Charcoal - 99.48 wt.%.

IMC used 96% concentration.

The method of application of the stimulator is as follows.

The processing of cuttings, for example, pears, red currants, honeysuckle, plums, gooseberries, sea buckthorn, Indian chrysanthemums, Izumbar violets, cloves, roses, is carried out by immersing the basal part of the cuttings moistened with water in the root root stimulant powder by about 1 cm, at this stimulator consumption of 10-20 mg per stalk. The treated cuttings are planted in moist soil - sand, sand with peat or in another substrate.

Processing before planting seedlings of fruit, berry and ornamental crops, for example blackcurrant, rosehip, lilac, is carried out by soaking the root system of the seedling in a suspension of root formation stimulant "Root" concentration of 1 g / l for 6 hours.

A stimulant suspension is prepared by dissolving the required amount in 100 ml (1/2 cup) of hot water with further bringing to the desired volume to create the necessary concentration.

The treatment of seedlings, for example, apple trees, is carried out by soaking the root system of the seedling in a suspension of a stimulant concentration of 1 g / l for 6 hours.

The flow rate of the working solution (suspension of the stimulator) 5 l / 5 plants.

When transplanting shrubs and trees 10 days after planting in the ground, a suspension of the root stimulant “Root” is irrigated under the root, with a flow rate of 5-10 liters per tree, depending on its size.

When treating cuttings and seedlings with a patented stimulator, most of it is localized near the application site due to the fact that the charcoal, which is part of the stimulator, adheres well to the cuttings, allowing a rather long time to keep the stimulator near the application site, which makes it possible to extend the stimulator cuttings and contributes to an increase in the formation of the root system and, thereby, helps to increase the survival rate of cuttings and improve their growth.

In addition, the presence of charcoal prevents the decay of cuttings, and the presence of potassium and trace elements in it helps rooting.

Patented stimulant is well compatible with other drugs (growth regulators, with other auxins, as well as gibberellin, etrel), fungicides (benlat, galangal, benomyl, ditan, foundationazole).

When treating cuttings or seedlings, the stimulator does not exhibit phytotoxicity, resistance does not occur, the use of the stimulator does not affect the variation of crops in crop rotation.

To confirm the effectiveness of the patented stimulant for a number of years, tests were carried out that showed the following.

The control was taken from cuttings or seedlings treated with IMC solutions of a concentration of 50 mg / l for 1 day.
