RU2385558C2 - Method for pre-planting treatment of potato tubers - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: prior to planting potato tubers are couched. As sprouts appear, they are treated with snow and then thawed snow water with nutritional substances dissolved in it. In process of treatment with thawed water it is complemented with leskenit in amount of 1-2% of weight amount of tubers and 0.01-0.02% p-amino-benzoic acid dissolved in ethyl alcohol.

EFFECT: method makes it possible to reduce costs for potato growth.

Description

The invention relates to the field of agriculture and can be used in the preparation of seed material for planting.

There is a method in which, before planting, the tubers are treated with snow 4-5 times every 5-8 days with the addition of nutrients (AS 1727604, IPC A01C 1/00, 1992).

In the known method, the planting of tubers is carried out manually, and introduced microelements together with snow significantly increase the cost of implementing the method. When mechanized planting sprouts break, which reduces the effectiveness of the method.

The closest technical solution is the method in which the sprouted tubers are treated with snow mixed with natural zeolites, and the last treatment is additionally treated with melt water with the addition of molasses and corn paste (patent No. 2120716, IPC А01С 1/00, published on 10.27.1998 g.).

However, in the prototype method, not always available substances are proposed for use, which complicates the method and increases costs.

The technical result is a reduction in costs, expanding the range of natural agro-ore, increasing the efficiency of the method.

The claimed method differs from the known one in that clay marl leskenite is added to melt water in an amount of 1-2 kg per 100 kg of potato and para-aminobenzoic acid (PABA) is introduced in a concentration of 0.01-0.02%, previously dissolved in alcohol.

Unlike the zeolite-bearing rocks used in the prototype, leskenite (clay marl, birthplace of the Republic of North Ossetia-Alania) has an alkaline reaction of the environment (pH 8.40) with a higher content of calcium, macro- and microelements, and most importantly, a sufficient amount of iodine .

Margel is a rock transitional between carbonate and clayey, containing up to 25-35% calcium (CaCO ₃ ).

Leskenite contains in 1 kg of gross forms of calcium - 245 g, phosphorus - 2.5 g, potassium - 166 g, sodium - 6.4 g, magnesium - 21.1 g, manganese - 1.43 g, iron - 22 g, copper - 40.5 mg, zinc - 126.2 mg, lead - 27.8 mg, cobalt - 27.8 mg, iodine - 2.2 mg at pH 8.46.

The macromicroelement-rich composition of leskenite, dissolved in snowy water together with PABA, provides stimulation and nutrition of sprouts, their safety at low temperatures, and resistance to disease, since the calcium content reduces the incidence.

The method is as follows.

During the germination period, seed tubers are treated several times with snow (as an analog) and, in contrast to the last treatment, leskenite is dissolved in melt snow water at the rate of 1-2 kg per 10 liters. PABA was added to this mixture at a concentration of 0.01-0.02%, previously dissolved in alcohol.

This amount provides the processing of potatoes. Clay particles contained in leskenite help strengthen the sprouts during mechanized planting, and PABA is a stimulator of plant growth and development.

The advantage of marl-like clay is that a high calcium content is a protective layer for the penetration of diseases.

Example. In mid-January, seed tubers were laid for vernalization in the amount of 100 kg. When the shoots appeared, a 2 cm layer of snow was applied. With an interval of 7-10 days, 3-4 treatments were performed. During the last treatment, 1-2 kg of leskenite was dissolved in melt snow water (10 l).

100 g para-aminobenzoic acid was dissolved in 50 g of ethanol and added to the dissolved mixture of leskenite.

The results of the experiments are summarized in table.

The data in the table indicate the advantage of the proposed method for yield (282 kg / ha) and a decrease in incidence from 23 in the prototype to 12% in the claimed object.
