RU2201079C2 - Modifier-stimulator for treating plants and method of using the same - Google Patents

Abstract

FIELD: agriculture. SUBSTANCE: method involves wetting seeds; sprinkling and watering plants, with all mentioned processes using oxalic acid of 0.001-0.03% concentration; settling for 0.5-1 hour in case of treating plant part other than roots; sprinkling or watering plants during the whole growing period. Method allows plant to be grown in open or protected ground, stability of plants to unfavorable environment factors to be enhanced, form of plant to be changed, its ornamental properties to be increased and plant aging process to be inhibited. Oxalic acid used as chemical agent added to water or sprinkling liquid suppresses development of harmful and unwanted organisms in soil and on surface of plant, reduces separation of flower and ovary from vegetable plants. EFFECT: increased efficiency and simplified method. 3 cl, 4 tbl

Description

 The invention relates to agriculture, namely to the use of chemicals for growing plants in open and closed ground.

 Known plant growth stimulant (A.S. USSR 1119646, M. Cl. (6) A 01 N 37/04). According to this invention, oxalic ammonium is used as a plant growth promoter.

 The proposed technical solution allows by pre-sowing treatment of seeds with an aqueous solution of oxalic ammonium concentration of 0.00047 mol / l to increase plant growth, leaf surface area, grain yield.

 The composition of the stimulator allows it to be used for pre-treatment of grain crops. For the same purposes, it is recommended in the book. "Agricultural biotechnology". / Ed. Acad. RAAS V.S.Shevelukhi. M.: High School, 1998

 Closest to the claimed technical solution is the treatment of seeds in order to increase the energy of germination, germination and yield with a solution of succinic acid (source - the above book. S.408).

 The composition of the stimulator limits its use by pre-sowing seed treatment. Moreover, the effect on the phenotype of the plant is limited. In addition, succinic acid, as well as oxalic ammonium, are less commercially available products than offered.

 The invention is aimed at expanding the functionality of a plant growth stimulator.

 The solution is achieved by using oxalic acid and / or its calcium and / or magnesium salts formed as a result of dissolution of oxalic acid in water as a modifier of plant development.

 Compared with the known technical solution, the proposed solution allows not only to pre-sow seed treatment, but also to modify the development of plants by affecting the root system and the aerial part of the plant.

 Oxalic acid is introduced into the water in dry form or may be previously dissolved in water for volume dosing.

 With non-root treatment of plants, sediment of calcium and magnesium oxalates is sedimented. With root treatment, sedimentation of oxalates is not performed.

 Modification of plant development proceeds in several directions at the same time: increasing resistance to adverse environmental factors, changing the shape of plants, increasing their decorative properties, slowing down the aging process of plants, suppressing the development of harmful and undesirable organisms in the soil and plant, eliminating the decay of flowers and ovaries of vegetable plants.

 Strengthening resistance to adverse environmental factors was observed on the example of an aloe plant. When grown in room culture, this plant rarely blooms even at the age of 10 years. Aloe plants watered with the addition of oxalic acid bloom starting from the age of 4 and at the same time (December) as aloe trees growing in open ground, for example, in Algeria.

 Changing the shape of the plant and increasing its decorative properties is to reduce the inter-nodal distance.

 Slowing down of the aging process was observed on a plant of cucumber cultivar "Parisian Gherkin". When growing this annual plant in a greenhouse culture, it vegetated for 18 months and fruiting for 16 months (modification was made by soaking the seeds, spraying and watering the plants with 0.0011 wt.% Oxalic acid solution). Moreover, the extension of plant life was observed without the use of such techniques as plant rejuvenation by pruning, rooting of young shoots, etc.

 In the soil irrigated with water with the addition of oxalic acid, there are no pests such as nematodes, wireworms, and unwanted animals like earthworms.

 Despite the useful function of earthworms in the soil, their presence near the root system of cultivated plants is undesirable. Earthworms can transmit disease. In addition, the products of the metabolism of worms can be absorbed by the roots of plants and enter plants and fruits. In this case, the organoleptic properties of root and tubers and aboveground fruits are reduced. The presence of earthworms is undesirable when growing ornamental plants in greenhouses and indoors.

 When watering vegetable plants, 0.0011 wt.% Oxalic acid solution is eliminated or minimized the loss of flowers and ovaries.

 The information given is given in Tables 1-4.

The soil mixture in which aloe, pepper, cucumber and potato were grown was prepared as follows. Garden soil is taken, where there is always material from at least one of the harmful or undesirable animals: wireworms, nematodes, earthworms. Earth sifted. Humus and ash are taken, which are also sifted. In addition, carbamide and superphosphate are taken. The components are mixed in the following ratio, g:
Garden Land - 500
Humus - 494
Ash - 2.5
Urea - 1.5
Ground superphosphate - 2
The soil, which has been irrigated for a long time with a solution of oxalic acid, becomes structured, finely lumpy, loose, suitable for cultivating plants.

 In general, the beneficial effect of soil treatment with a solution of oxalic acid on the entire soil – plant complex was noted.

 When watering plants with oxalic acid solution, the calcium and magnesium carbonates and bicarbonates contained in the soil are gradually replaced by calcium and magnesium oxalates, which serve as a source of these elements in the soil, while at the same time they do not have harmful effects on plant roots like carbonates and bicarbonates. Calcium and magnesium in the form of oxalates are not susceptible to leaching from the soil, as is the case with carbonates.
