Abstract

FIELD: agriculture, plant growing. SUBSTANCE: seeds before sowing and plants at vegetation period were treated with an aqueous solution containing microquantity of hydrogen peroxide, copper ions and oxalic acid. EFFECT: enhanced effectiveness of method, accelerated maturation.

Description

 The invention relates to crop production and can be used both for pre-sowing seed treatment and for growing plants in open and closed ground.

 Known methods of stimulating plant growth both in pre-sowing seed treatment, and when growing plants in open and closed soils USSR N 704576, class A 01 N 59/20, 1979.

 Closest to the technical nature of the proposed method is a method of stimulating plant growth ed. USSR N 1544334, class A 01 N 59/20, A 01 C 1/00, 1990.

The method consists in the fact that the pre-sowing treatment of seeds and watering of plants during the growing season is carried out with aqueous solutions containing trace amounts of hydrogen peroxide 10 ^-6 10 ^-4 mol / l and copper ions 10 ^-6 10 ^-5 g-ion / l.

 However, this method is not effective enough.

 The aim of the invention is to increase efficiency and shorten the growing season.

This goal is achieved by treating the seeds before sowing and watering the plants during the growing season with aqueous solutions containing trace amounts of hydrogen peroxide 10 ^-6 10 ^-4 mol / l, copper ions 10 ^-6 -10 ^-5 g-ion / l, oxalic acid in an amount of 0 , 1 0.2 mg / l.

 A distinctive feature of the proposal is the introduction of oxalic acid in the composition for processing plants in an amount of 0.1 0.2 mg / l, which ensures the achievement of a positive effect.

 Comparison of the claimed technical solution with the prototype made it possible to establish its compliance with the criterion of "novelty."

 Upon receipt of other known methods in this field, the features that distinguish the claimed invention from the prototype were not found and therefore it provides the claimed technical solution according to the criterion of "significant differences".

Example 1. The seeds of tomato on the eve of sowing are treated with an aqueous solution of the composition H ₂ O ₂ 10 ^-4 mol / l, C ⁺² 10 ^-6 g-ion / l, oxalic acid 0.1 mg / l at the rate of 3 l of solution per 1 kg of seeds . Processing is carried out for 25 minutes with stirring, after which the water is drained, and the seeds are dried in air. The seeds are germinated in the greenhouse and watered once every 3 to 5 days with a solution of the same composition. After 2 months, the plants are planted in the field. Before harvesting, they are watered with a solution containing hydrogen peroxide and copper ions in the same quantities as at the beginning, three to four times as the soil dries. Similar operations with the same number of seeds are carried out according to standard agricultural techniques. In control, watering is carried out with the same water and at the same time, but without additives. In the field, watering plants in the experiment is carried out through an intermediate tank, in which immediately before watering a solution of hydrogen peroxide, copper sulfate and oxalic acid is prepared.

 Accelerated plant growth is observed both in the greenhouse seedlings grow 7-8 days faster and in the field.

The first crop from the experimental plot was harvested 11 13 days earlier than from the control. Productivity compared to control is 140%
Example 2. Onion seeds without pre-treatment are planted in a greenhouse in closed ground and watered once a week with an aqueous solution containing hydrogen peroxide at a concentration of 10 ^-5 mol / l, copper ions at a concentration of 10 ^-6 g-ion / l and oxalic acid 0.1 mg / l. Copper ions are added to irrigation water twice: immediately after the emergence of plants and during the ripening period. In control, water without additives.

 The yield increase in the experiment 56% Biomass was collected 12 to 14 days earlier than in the control.

Example 3. Geranium sprouts are watered with an aqueous solution of the composition: H ₂ O ₂ 10 ^-5 mol / L, C ⁺² 10 ^-6 g-ion / L, oxalic acid 0.2 mg / L. Sprouts are watered every three days, but with an aqueous solution of only hydrogen peroxide of the same concentration. After the appearance of flowers, stop watering.

In control irrigation water without additives. The gain in the experiment of 30 32% biomass increases compared with the control by 30%
Example 4. The same as in example 3, but they take rose sprouts. Watered with an aqueous solution of the composition: H ₂ O ₂ 10 ^-4 mol / L, C ⁺² 10 ^-6 g-ion / L, oxalic acid 0.1 mg / L. In control irrigation water without additives. Every three days, sprouts are watered only with a solution of hydrogen peroxide at a concentration of 10 ^-5 mol / L. The gain in experience 25 30%
Example 5. The same as in examples 3 and 4, but take sprouts of cloves. Watered with an aqueous solution of the composition: H ₂ O ₂ 10 ^-5 mol / L, C ⁺² 10 ^-6 ion / L, oxalic acid 0.2 mg / L. Every 4 days, sprouts are watered with water of the same composition. In control irrigation water without additives. The gain in experience -25 30%
The examples show that the proposed method for treating seeds and watering plants with a solution of the specified composition is non-specific and has a pronounced positive effect on various crops. Compared with known methods of stimulating plant growth, the proposed method is economically advantageous and environmentally friendly.
