Abstract

This invention relates to agriculture. The purpose of the invention is to increase the yield. The proposed composition for regulating the growth of grapes contains gibberellin, the triethanolamine salt of crosoxyacetic acid (krezacin) and water in the following ratio of components, wt.%: Gibberellin 0.0006-0.005, krezacin 0.0005-0.002, water else. The effectiveness of the proposed composition is established on seedless Kishmish grapes (black and white). The use of the proposed composition allows to increase the yield of winter-resistance of grapes in comparison with the known composition and control. 3 tab.

Description

The invention relates to agriculture and can be used to control the fruiting capacity of a wine dairy.

The aim of the invention is to increase the yield.

The composition for regulating the growth of grapes contains gibberellin (GK), the cresoxyacetic acid triethanolamine salt (krezacin) and water in the following ratio of components, May .:

Gibberellin0,0006-0,005

Krezacin0,0005-0,002

Water Rest

Processing of grapes with known growth regulators, HA and kreeacin (KR) is used as analogs of comparison.

In laboratory experiments studied the activity of a mixture of HA and krezacin in various

ratios: GK 0.02–0,0001% and KP0.01– 0.0001%. The most effective compositions GK 0.0006-0.01% and CD 0.0001-0.002, which are included in the scheme of field experiments.

Example. Prepare solutions of individual components of different concentrations. HA is preliminarily dissolved in ethyl alcohol at the rate of 1 g 10 ml and the concentration of the aqueous solution is adjusted to 100 mg / l (production dose) and 25 mg / l, respectively. CU at a concentration of 10 mg / l. 0 Of the components in the indicated concentrations, formulations are prepared, the working volumes of which are brought to 10 liters. In parallel, working solutions of individual components are prepared and the volume of each of them is brought up to 10 liters. Working solutions of the composition and individual components are poured into backpack sprayers (ORP-1) and treated with vines at a rate of 1 l per bush.

The treatment is carried out at the end of mass flowering (after 95% of the caps are deposited) once until complete wetting. The control are the bushes, sprinkled with water. At the end of the growing season, the number of years in a bunch, the mass of years and clusters, the density

clusters, sugar content year and yield of plants. The object under study is the seedless grape Kishmish (black and white oval),

Table 1 shows the effect of growth regulators on the yield of Kishmish black grapes.

The most effective formulations for treatment are the compositions of HA 6 + CU 20 mg / l; GK 12,5+ CU 10 mg / l; GK 25 + KP 10 mg / l and GK 50 + KP 5 mg / l.

Table 2 shows the effect of growth regulators on the development of the year and the bunch of grapes, in 1987.

Table 3 presents data on the winter resistance of Kishmish black grapes when treating plants with growth regulators, observed in 1987.

The results of the experiment (Tables 1–3) show that the compositions at the recommended concentrations allow an increase in yield and winter hardiness with a slight decrease in sugar content per year.

In the composition with a concentration of HA of 0.0025% + CU 0.001% the amount of HA is four times less than in the production dose, and 2-3 times less than in the known one.

Claims (1)

The use of the proposed composition on grapes stimulates the formation of inflorescences, enhances the development of the year and clusters (the yield of plants increases and the product quality improves); it increases the winter hardiness of plants, reduces the dose of a scarce and expensive GC preparation widely used in viticulture (150 g / ha), reduces the laboriousness of treating plants using mechanized spraying and reducing its multiplicity, reduces the risk of environmental pollution with high doses of biologically highly active GK. The invention The composition for regulating the growth of grapes, containing gibberellin and water, is characterized in that, in order to increase the yield, it additionally contains the tri-ethanolamine salt of croxioxyacetic acid in the following ratio, wt.%: Gibberellin Triethanolamine salt of crosoxyacetic acids Water 0,0006-0.005 0,0005-0,002 Else thirty Table 1 table 2 Table 3
