Description

The invention relates to the field of agriculture and is intended to increase the energy of germination, seed germination and yield of crops.

It is known to use the growth preparation Mival and bischofite solution for presowing treatment of seeds of grain crops [1].

It is known to use aqueous solutions of saturated dicarboxylic acid for treating seeds of grain crops and spraying plants during the growing season [2].

It is known to use aqueous solutions of hydrogen peroxide, copper ions and oxalic acid for treating seeds of grain crops and spraying plants during the growing season [3].

Known drugs can increase productivity, but require several operations during processing.

The invention is directed to the use of copper (II) bismalonamide nitrate of the formula (I) Cu (NO ₃ ) ₂ · 2CH ₂ (CONH ₂ ) ₂ as a grain growth promoter. The possibility of using low concentrations while ensuring high stimulating efficiency compares favorably with copper (II) bismalondiamide nitrate from the currently used growth stimulators.

The technical problem solved by the invention is the expansion of the range of plant growth stimulants.

The technical problem is solved in that it is proposed to use copper (II) Cu (NO ₃ ) ₂ -2CH ₂ (CONH ₂ ) ₂ bismalondiamide nitrate as a growth promoter.

The technical result is to accelerate the start of ripening of crops, increasing the content of chlorophyll in the leaves and yield of grain crops.

Copper (II) bismalonamide nitrate Cu (NO ₃ ) ₂ -2CH ₂ (CONH ₂ ) _{2 of} formula (I) is a blue crystalline powder, readily soluble in water.

It is proposed to use copper (II) bismalondiamide nitrate as a growth promoter in the pre-sowing treatment of grain seeds and to treat vegetative plants with a 0.001% aqueous solution of copper (II) bismalondiamide nitrate.

The proposed solution of the claimed stimulant is prepared according to known methods as follows.

Initially, 1 g of copper (II) bismalondiamide nitrate is weighed on an analytical balance and dissolved in 1000 ml of distilled water. Then, an aliquot of 10 ml was taken from this solution and adjusted in a volumetric flask to 1000 ml to obtain a 0.001% aqueous solution.

The invention is illustrated by the following examples.

Example 1. Laboratory experiments.

Study of the effect of a 0.001% aqueous solution of copper (II) bismalondiamide nitrate on the germination of wheat seeds.

Assessment of biological activity as a growth promoter of copper (II) bismalonamide nitrate was carried out on seeds of spring wheat of the Moskovskaya-35 variety. The determination of germination energy and laboratory germination was carried out according to GOST 12038-84. Seed germination energy - percentage of germinated seeds in 3 days, laboratory germination - percentage of germinated seeds in 7 days.

In each Petri dish on two layers of moistened filter paper, 100 pieces of spring wheat seeds of the Moskovskaya-35 variety were evenly distributed. After that, the seeds were poured with 10 ml of nutrient solution and placed in a thermostat. Seeds were germinated at a temperature of 27.5 ± 2 ° C for 7 days.

As a working solution, a 0.001% aqueous solution of copper (II) bismalondiamide nitrate was prepared. Germination energy and laboratory germination of seeds soaked in the test solution were compared with germination energy and laboratory germination of seeds soaked in distilled water. The experiment was laid in four repetitions.

The arithmetic average of the results of determining the germination energy and laboratory germination of the analyzed samples was taken as the result of the analysis.

Wheat seeds of the Moskovskaya-35 variety are soaked in distilled water (control) and in a solution of 0.001% copper (II) bismalondiamide nitrate for 2 hours at the rate of 1 liter of solution per 1 kg of seeds. After soaking, the seeds are dried to the sowing condition, stored in paper bags and sown. Comparative data on the energy of germination and germination of seeds are given in table 1.

From the analyzes of Table 1, it can be seen that copper (II) bismalondiamide nitrate has a significant stimulating effect.

Example 2. Field experiments.

Study of the effect of a 0.001% aqueous solution of copper (II) bismalondiamide nitrate on the chlorophyll content in leaves and wheat yield.

Assessment of biological activity as a growth promoter of copper (II) bismalonamide nitrate was carried out on seeds of spring wheat of the Moskovskaya-35 variety.

On leached chernozemic soils with a humus content of 6.8%; mobile phosphorus - 127.7 mg / kg; exchange potassium - 143.3 mg / kg; a crop was grown - spring wheat of the Moskovskaya-35 variety. The method was carried out with four repetitions. The total area of the experimental plot was 10 ha.

In field experiments, spring wheat plants of the Moskovskaya-35 variety were stimulated by soaking the seeds with a 0.001% aqueous solution of copper (II) bismalondiamide nitrate. In control plots, the seeds were soaked with water.

Comparative data on the content of chlorophyll in the leaves are given in table 2, for productivity - in table 3.

From the table it follows that when treated with a stimulant solution, the germination energy increases by 18.1%, and germination - by 16.3%; productivity - by 14.2% (2005) and 12.6% (2006).

Thus, the use of copper (II) bismalondiamide nitrate can significantly increase the energy of germination and germination of seeds, as well as the yield of wheat variety Moskovskaya-35 and allows you to expand the range of plant growth stimulants used. The possibility of using low concentrations while ensuring high stimulating efficiency, taking into account its comparative availability and low cost, compares favorably with copper (II) bismalonamide nitrate from the currently used growth stimulators.
