Composition for stimulating the growth of agricultural crops (options)

 

(57) Abstract:

The invention relates to agriculture, in particular to chemical agents stimulating the growth and nutrition of plants. The application of the composition may for seed treatment, foliar application and the main application. The composition according to the first embodiment is a solution or suspension, where as growth substances take humates sodium and/or potassium and/or ammonium 8-10%, as a source of copper - copper sulphate or douglastown copper 5-11%, and as a source of boron - borax, boric acid or solid products containing more than 2% of boron obtained by recycling the mother solutions in the production of boric acid from natural raw materials 8-73% water and the rest to 100%. The composition according to the second variant is a powder, where as growth substances take humates sodium and/or potassium and/or ammonium 8-10%, as a source of copper - copper sulphate or douglastown copper 5-11%, and as a source of boron - solid products containing 1.6 to 2% of boron obtained by recycling the mother solutions in the production of boric acid from natural raw materials, the rest to 100%. This composition has a high efficiency and lower consumption of active component personnel.

Group the invention relates to agriculture, in particular to chemical agents stimulating the growth and nutrition of plants.

Effective impact on the growth and development of plants have growth substances and micronutrients. Known compositions comprising these substances, and their "delivery" is accomplished either through the introduction into the soil together with fertilizers, either through pre-sowing seed treatment, or by foliar feeding.

Known organic fertilizer / Patent RF 2054404, MKI C 05 G 3/00, publ. 20.02.96/, containing the basic elements of nutrition: nitrogen, phosphorus, potassium, trace elements like molybdenum, manganese, and Rostovon substance - modified lignin. Additionally fertilizer includes calcium, sulfur, chlorthalidone, dimethylsulfoxide and binder. The fertilizer is intended for native soil, is cause a slow, thereby reducing the loss of nutrients from leaching. However, the properties of the composition rule out the possibility of its application for foliar application and seed treatment, and therefore does not allow to use the full potential of such an effective growth substances, which is known to gum the RF 2092054, MCI A 01 N 59/00, publ. 10.10.97/ containing sources of micro-ingredients: zinc, boron, manganese, copper, and fine hydrophobic silica as a growth substance. The presence of boron and copper which have become scarce in most regions, is the positive side of the drug, however, the low stimulatory capacity of hydrophobic silica as germ substance causes a low efficiency of the product as a whole.

As a prototype of the selected composition for stimulating the growth of agricultural crops /Patent RF 2086126, MKI A 01 N 31/08, publ. 10.08.97/ containing monoethanolamine as growth substances - 12-20%, boric acid 2-5%, copper sulphate - 10-16% and water - the rest is up to 100%. Composition increases yields, can be used not only for pre-treatment of seeds, but also for foliar feeding. However, the relatively low efficiency of monoethanolamine as growth substances (as used substance in the second analogue) leads to the fact that the consumption of reagents per ton of processed seeds to obtain a significant increase in the crop yield significantly overestimated. In addition, since the known composition are presented in liquid form, is practically eliminated is giving the drug to stimulate crop growth highly effective humates, boron and copper components is associated with certain difficulties, because:

in preparation, giving an acid reaction, humates become trudnousvoyaemoe form, while the metals remain in the form of compounds available to plants,

in preparation, giving an alkaline reaction, on the contrary, humates, and the metals are transferred into unassimilated form.

The basis of the invention is the task of creating a composition for stimulating the growth of agricultural crops with enhanced efficiency, contributing to the reduction of the active components (boron, copper, and growth substances) per tonne of processed seeds.

In the first case the problem is solved in that the composition for stimulating growth of crops containing Rostove substance, the source of boron, a source of copper and water, in which, according to the invention, as growth substances take humates sodium and/or potassium and/or ammonium as a source of copper take copper sulphate or douglastown copper, and as a source of boron take borax, boric acid or solid products containing more than 2% of boron obtained by recycling the mother solutions in the production of boric acid from natural>Copper sulphate or Duhlata copper - 5-11

Borax, boric acid or solid products containing more than 2% of boron obtained by recycling the mother solutions in the production of boric acid from natural raw materials - 8-73

Water - the Rest is up to 100

The basis of the invention the second additional task of creating a composition for stimulating the growth of agricultural crops, is applicable not only for presowing seed treatment and foliar feeding, but also for the main application, including in combination with mineral fertilizers, i.e., the expansion of technological possibilities of use.

Both tasks solves the second version of the composition for stimulating growth of crops containing Rostove substance, the source of boron and a source of copper, which, according to the invention, as growth substances take humates sodium and/or potassium and/or ammonium as a source of copper take copper sulphate or douglastown copper, and as a source of boron to take solid foods containing 1.6 to 2% of boron obtained by recycling the mother solutions in the production of boric acid from natural raw materials, in the following ratio of components, wt.%:

Humates is operasie 1.6 to 2% boron, obtained by the utilization of mother solutions in the production of boric acid from natural raw materials - the Rest is up to 100

The drug in the first embodiment is a solution or suspension, according to the second variant powder. For seed treatment and foliar formulations both versions additionally dissolved in the water.

The authors experimentally found that the addition of copper sulphate used in the prototype as a source of copper, can be used Duhlata copper. With the introduction of duhalista copper its number is closer to the lower value of the specified interval, with the introduction of copper sulphate to the upper value.

The authors also experimentally found that the addition of boric acid used in the prototype as a source of boron, in the proposed structure can be used for solid products obtained by recycling the mother solutions in the production of boric acid from natural raw materials, and borax (the latter only in the first embodiment). With the introduction of boric acid (or borax) her number is closer to the lower value of the specified interval, with the introduction of solid boron-containing product obtained by the utilization of mother solutions ness, be used birmanie fertilizer grades a, B, C, G or borodalopatoy fertilizer with boron from 1.79 to 3.5%. This second task (the second variant of the invention) is solved with the introduction into the composition of the solid products obtained by the utilization of mother solutions in the production of boric acid from natural raw materials with boron in the range of 1.6% to 2%.

Below are examples of specific implementation that uses the following components:

- boric acid - GOST 18704-78,

- borax - GOST 8429-77

- birmanie fertilizer grades a, B, C, G - TU 113-12-151-84

- borodalopatoy fertilizer - GOST 10347-63

- copper sulphate - GOST 19347-84

- Duhlata copper - GOST 4167-74

- HUMATE sodium (grade a) - THE OP 2431530-006-27402873-98

The results are given in table. 1.

3 g of the indicated composition was dissolved in 0.5 liters of water and the resulting composition was used to treat 10 kg of seeds of cucumber variety "Libelle". Crop yields in greenhouses in relation to the control (without treatment) was 1.1 kg/m2that represented an increase of 39%.

Example 4.

Mixed 60 wt. including bormaganiga fertilizer grade (with a boron content of 2.4%, 6 wt.h. duhalista copper, 10 wt.h. of sodium HUMATE and 24 wt.h. water.

300 g of the indicated composition was dissolved in 30 liters of water and the resulting composition was used to treat 1 ton of seed oats. The yield in the field experiment relative to the control (without treatment) was 3.9 t/ha, corresponding to the ora of 1.92%), 8.3 wt.h. copper sulphate and 8.3 wt.h. of sodium HUMATE.

300 g of the specified dry composition was dissolved in 30 liters of water and the resulting composition was used to treat 1 ton of barley varieties "Belogorsk". The yield in the field experiment relative to the control (without treatment) was 7.7 kg/ha, which corresponds to an increase of 22%.

Example 6.

Mixed by 83.4 wt.h. bormaganiga fertilizer brand G (boron content of 1.92%), 8.3 wt.h. copper sulphate and 8.3 wt.h. of sodium HUMATE (composition used in example 5).

The specified dry composition used for the main application in combination with mineral fertilizer at the rate of 0.1 kg of the composition per 100 kg of mineral fertilizers in physical weight. A production experiment was conducted for potato varieties "Detskoselsky". Yield increase in comparison with the background of fertilizers without the proposed drug was 4.1 t/ha, which represented an increase of 26%. Thus, unlike the prototype of the proposed structure provides a significant increase in crop yields not only when it is used for seed treatment, but also in the basic application cultivation or plowing.

Example 7.

Mixed 84 wt. including bormaganiga unuu dry composition used for the main application in combination with mineral fertilizer at the rate of 0.1 kg of the composition per 100 kg of mineral fertilizers in physical weight. A production experiment was conducted for cabbage varieties "Kharkov late". Yield increase in comparison with the background of fertilizers without the proposed drug 10.5 t/ha, which corresponds to an increase of 35%.

In the declared us the composition ratio of HUMATE, sources of boron and copper are selected such that they not only suppress due to its acid-base reaction activity of each other, but are mutually reinforcing. Is a synergistic effect, which is manifested in the active stimulation of crop growth, which has helped reduce the consumption growth substances boron and copper to the processing of 1 ton of seeds and receive higher yields.

To confirm the achievement of a new technical result data of field experiments with potatoes varieties "Table - 19", received in State Agrarian University, St. Petersburg) (table.2).

The comparison with the results of experiments on potatoes that are cited in the article (Dokl. RAAS, 1997, N 13, C. 19-20) corresponding to the yield increase 20 and 42.6% compared with the control without fertilizer, shows a significant excess of the effectiveness of the claimed composition on known. In addition, according to the authors of this staterna 200-300 g of seeds, per 1 ton of seeds will be expended approximately 6.7-10 kg of the composition, whereas consumption, we stated composition is 200-300 g per 1 ton of seeds.

Vegetation experiments showed that the replacement of sodium humates humates potassium or ammonium provide similar effects on the yield of agricultural crops.

Under production conditions it is shown that the claimed product can effectively be used for foliar feeding.

The inventive composition was used under the trade name "Humein". It enhances the germination energy, improves the development of root systems, prevents the dropping of flower ovaries and fruits, enhances ripening grain, potatoes, accelerates ripening. "Humein increases the protein content of the grain, the starch in potatoes, ascorbic acid in all investigated cultures. In addition, in the production of nitrates reduction, and plants in General less affected by fungal diseases.
