Abstract

FIELD: agriculture.

SUBSTANCE: hybrid potato seeds are affected by phenolic compounds of coniferous trees. For this purpose, crushed cones of coniferous species are used, that are held in the thermal mineral water "Karmadon" at the ratio of 1:10 for 4-5 hours. Thereinafter the hybrid potato seeds are soaked with 40-60 minutes of exposure, followed by planting in the ground.

EFFECT: invention will allow to improve the efficiency, germination and productivity of potato seeds while reducing costs due to the recycling of wood waste.

Description

The invention relates to the field of agriculture, in particular to crop production, and may find application in the propagation of breeding samples of hybrid potato seeds.

There is a method in which pre-sowing seed treatment is carried out with biologically active substances extracted from aspen wood (patent No. 2476052 from 02.27.2013, IPC A01C 1/06, A01C 1/08).

However, the known method is somewhat complicated by water extraction from wood, which is limited by the duration of the growing season, when you can use this stimulating substance only in the spring for spring crops of wheat and barley.

There is also known a method in which, to increase the yield of wheat and potatoes, a preparation is prepared, one of the gradients of which is fir greens (patent No. 2437285, published December 27, 2011, IPC A01N 65/00, A01N 39/00, A01P 3/00, A01P 21 / 00).

Known technical solution includes a number of ingredients, which complicates the method. In addition, a chemical substance - 2.4 dichlorophenoxyacetic acid and lichens is added to fir greens, which complicates the method.

There is also known a method where the seeds of legumes before sowing are treated with wood aspen (patent No. 2523294 from 07.20.2014).

This technical solution only increases the energy of germination and germination, excluding disease indicators and grass survival in joint crops.

There is also a method of stimulating the acceleration of seed germination, which is treated with an extract of needles (patent No. 2569017 from 11/20/2015, IPC А01С 1/06).

The specified technical solution is also complicated by the fact that other ingredients are added to the coniferous extract: ordinary pine and juniper.

The closest technical solution is a method where phenolic compounds of woody greens are used as a stimulant (patent No. 2571936 dated 12/27/2015, IPC A01N 65/00, A01P 21/00).

In the prototype method, chopped spruce green wood is poured with a 3-5% aqueous sodium hydroxide solution, mechanized mixing at a temperature of 45-50 ° C, followed by filtration, separating the solid fraction. All these methods of technical solution complicate the method and increase costs.

The technical solution is to reduce costs, increase the efficiency of the method by utilizing wood waste.

The technical solution of the claimed object lies in the fact that, in contrast to the prototype method, crushed cones of coniferous species are used, which are kept in Karmadon thermal mineral water in a ratio of 1:10 for 4-5 hours, after which hybrid potato seeds are soaked during exposure 40-60 minutes, followed by sowing in the ground.

The method is as follows.

Cones of spruce and pine, which fall from the trees during spring and summer, are collected, crushed together with the seeds present in them, and soaked in mineral water.

Mineral water (local origin) “Karmadon” contains boron more than 100 mg / l (as boric acid), lithium 26 mg / l, strontium 7 mg / l, fluorine 7.5 mg / l, iodine 0.9 mg / l , bromine 9.5 mg / l, iron 29 mg / l, silicic acid 105 mg / l. All Karmadon sources studied are thermal, the temperature of which reaches 40-60 ° C. These thermal springs are used as healing baths. Containing a complex of macro- and microelements in a mixture with crushed cones, they not only stimulate seed germination, but also prevent the disease of young seedlings.

Spruce and pine cones used in the experiment contain lipids, tannins, multi-terpene carbohydrates, bioflavonoids, oleic acid, resins, carotenes, essential oils, tannins. Essential oils contain a-pinene and b-pinene more than 10%, many macro- and microelements, compounds of the terpene series, biological active substances (iron, chromium, copper, phytoncides). These elements in combination have an antimicrobial effect, providing reliable protection of plants from diseases. The justification of the selected parameters of the method for preparing the solution for 4-5 hours, the exposure in the solution within 40-60 minutes is explained by the chemical composition of both components of the cones, acting as a stimulant.

Example 1

The experiments were carried out with hybrid seeds obtained from crossing a hybrid 733-65 (maternal form) and varieties Aurora (paternal form). Cones of spruce and pine in the amount of 100 g were soaked in 1 liter of Karmadon water for 4 hours. In a filtered solution, the seeds were soaked for 60 minutes and after drying, they were sown in the soil.

Example 2

In one liter of mineral water, 100 g of crushed cones of spruce and pine were soaked for 5 hours. The thermal water of the mineral spring had a temperature of 40 degrees. After filling with mineral water valuable substances contained in cones of conifers, biological potato seeds were soaked for 40 minutes, after which they were planted in the ground.

The results of the experiments are summarized in table:

From the above data in the data table shows that in the proposed embodiment, there was no damage to plants by viral and fungal diseases, not only from the aerial mass, but also from potato tubers. The germination and productivity of the proposed option had an advantage over control when using wood waste - shredded cones as a stimulator.

Claims (1)

A method of stimulating the growth and development of hybrid potato seeds, including exposure to phenolic compounds of conifers, characterized in that they use crushed cones of coniferous species, which are kept in the Karmadon thermal mineral water in a ratio of 1:10 for 4-5 hours, after which hybrid potato seeds are soaked at an exposure of 40-60 minutes, followed by sowing in the ground.
