Description

The invention relates to the field of agriculture and can be applied in crop production when growing various crops.

Known use as a means to increase crop yields of plant growth regulators: agate 25 K, immunocypitis, mival, albite, etc., belonging to different classes of chemical compounds and biological products [1].

Plant growth regulators increase the height of the stems, the mass of the aerial parts and roots, productivity, and also increase the resistance of plants to adverse environmental factors and diseases.

The task of the invention is to increase the efficiency of regulation of plant growth, productivity and resistance to bacterial, fungal and other diseases.

It is proposed to use drugs as plant growth regulators: urea peroxyhydrate (PHM) and M agro peroxide (PHMA) - nitrogen-oxygen fertilizers with plant protection properties against pathogens [2, 3, 4].

The method of obtaining the above drugs and their use are known [2, 3, 4, 5].

The preparations PGM and PHMA are complex chemical compounds of urea (urea) with hydrogen peroxide. PGM consists of the following components: 64.3% urea, 35% hydrogen peroxide and 0.15-0.25% citric or oxalic acids. An additional 0.5-5.0% sodium tripolyphosphate was added to the PHMA preparation.

In PHMA in production conditions it is advisable to introduce 0.5-12% of stabilizers (potassium, sodium, magnesium salts of phosphoric or silicic acids), 0.5-0.25% of any surfactant (OP-7, OP-10, twins or organosilicon) and / or directly when applied to the aqueous solution of the drug add trace elements (boron, molybdenum, magnesium, copper, zinc, cobalt, etc.).

PGM and PGMA as growth regulators can be used in the technological processes of cultivating potatoes, vegetables (cabbage, cucumber, tomatoes, radishes, etc.), cereals, legumes (barley, wheat, corn, rape, lupine, clover, flax, soybeans, beans, etc.), fruit and berry crops, as well as ornamental and indoor plants in horticulture, floriculture, forestry and home gardens, including the processing of seeds, tubers, seedlings, cuttings, seedlings of the above plants during preparation planting material, as well as for Neva and / or foliar feeding of plants.

The drugs are used in the form of 0.15-3.0% aqueous solutions for treating seeds, tubers, seedlings, etc. before sowing, planting and / or for spraying plants with foliar and / or watering the soil during root treatment.

Plants are sprayed with a solution with manual, tractor-mounted sprayers, and seeds, tubers manually or with special machines.

Below are the test data of plant growth regulators PGM and PGMA.

Example 1. The effect of PGM in comparison with urea (urea) and control on the growth and development of various varieties of potatoes was carried out on the 30th day of growing under vegetative conditions when they were introduced into the soil at doses of 50; one hundred; 200 g / m ² - are presented in table 1.

The best indicators of the height of the stems were obtained in the experiment with the use of PGM in the norm of 50 g / m ² . High doses of urea - 200 g / m ² - lead to a decrease in the weight of the aerial parts of potato plants in comparison with the control, and in variants using doses of 50 and 100 g / m ^{2 of} urea, the accumulation of vegetative mass was insignificant.

PGM, unlike carbamide, did not show a phytotoxic effect on potato plants.

The data obtained indicate the possibility of using urea peroxyhydrate and preparations obtained on its basis in small doses as plant growth regulators.

Example 2. The effect of the preparation of PHMA on seed germination, root system and flower growth was studied in a greenhouse at a temperature of 20-22 ° C and a humidity of 90%. Flower seeds were sown in boxes of 50 × 70 × 20 cm in soil (a mixture of 50% peat and 50% perlite). After sowing, the soil was treated with 0.15% aqueous solution of the drug in the norm of 1.0 l per box. Control - watering the soil with water. The results are presented in table.2.

In the stage of the first real leaf, the plants were peaked into cassettes with cells with a diameter of 30 mm, a height of 50 mm and processed twice with an interval of 10 days with a 0.15% aqueous solution of PHMA in the norm of 1.0 l per cassette. Control - water treatment. The effect on plant growth and the number of buds is presented in table 3.

Example 3. Thuja seeds (100 pcs.) Were planted in boxes of 70 × 50 × 20 cm in size, filled with soil (a mixture of 50% peat and 50% perlite), and were treated with 0.3% aqueous solution of PGMA in the norm of 1.0 l on the cassette. Control - watering the soil with water.

Lawn grass seeds were planted on the ground and watered with a 0.3% PGMA aqueous solution. The effect of the drug on germination, root system and plant height are presented in table 4.

Example 4. A field experiment to study the growth-regulating properties of PGMA on potatoes was carried out in the experimental field of the State Unitary Enterprise OPH Korenevo (Kraskovo, Lyubertsy, Moscow Region). We studied the effect on tuber germination, the development and productivity of Sante potatoes, plant damage, and tuber crop disease. The area of the experimental plots is 25 m ² , the repetition is fourfold, the placement is randomized. A PHMA preparation was sprayed with potato seeds before planting with a flow rate of 280 g / t in 10 l of an aqueous solution / t. Standard was ethine, a flow rate of 20 ml / t with spraying of plants in the phase of “onset of budding” (80 ml / ha). Potato planting was carried out on May 10, 2006; harvesting was carried out on August 28, 2006.

The results of determining the biometric parameters of plants in the “full bloom” phenophase are presented in Table 5, and the productivity of potato plants in Table 6.

The treatment of the tubers with the preparation had a stimulating effect on the height of the plants, the mass of the tops, the area of the leaf surface and the intensity of the formation of young tubers in comparison with the standard ethine and control.

The peroxide M agro preparation in the field had a positive effect on the growth, development and productivity of potato plants.
