Description

The invention relates to the field of agriculture and can be used to improve the sowing qualities of seeds, as well as increase crop yields.

A known method of presowing treatment of nightshade crops, where as a physiologically active substance for seed treatment is used an aqueous solution of dihydrate trioxoborate ethanolamine [1].

A known method of stimulating the germination of seeds of grain crops, including presowing treatment of seeds with an aqueous solution of bisethane-1,2-dicarbonate ethylene diammonium [2].

A known method of stimulating seed germination, including presowing treatment of seeds with an aqueous solution of tris (2,2-dichlorocyclopropylmethyl) borate [3].

Known methods can increase the energy and speed of seed germination and productivity, but are difficult to prepare and involve the use of more expensive drugs.

The invention is aimed at creating a method of presowing treatment of seeds and increase crop yields.

The technical problem solved by the invention is to expand the range of methods for presowing seed treatment and increase the productivity of bluegrass, cabbage and nightshade crops.

The technical result is to increase the energy of germination and germination of seeds of bluegrass, cabbage and nightshade crops, accelerating the onset of ripening, increasing yields, as well as expanding the arsenal of funds for this purpose.

This is achieved by using a tetrabornothiourea compound of the formula (NH ₄ ) ₂ B ₄ O ₇ · N ₂ H ₄ CS · H ₂ O as a means of increasing germination energy, seed germination and increasing the productivity of bluegrass, cabbage and nightshade crops.

Example 1. The seeds of bluegrass, cabbage and nightshade crops were soaked in aqueous solutions of tetrabornothiourea compounds of various concentrations until swelling, then germinated to determine the germination energy and laboratory germination according to GOST 12038-84 "Seeds of agricultural crops. Germination determination methods. "

Data on the effect of presowing soaking in solutions of tetrabornothiourea compounds on the germination energy and seed germination are given in Table 1.

Table 1 A drug The concentration of the solution,% Germination energy,% Germination,% Spring wheat Moscow 35 White cabbage Number one mushroom 147 Tomato White filling 241 Spring wheat Moscow 35 White cabbage Number one mushroom 147 Tomato White filling 241 The control Water 78 64 67 97 85 95 Tetrabornothiourea compound 0.001 83 73 79 96 85 95 0.003 89 82 89 98 92 98 0.005 87 76 81 97 89 96 0.010 82 68 71 97 85 95 0,030 71 52 64 96 83 93 0,050 54 41 51 83 78 82

From the data of Table 1 it follows that the optimal for pre-sowing treatment by soaking is a 0.003% aqueous solution of the tetrabornothiourea compound, during which the germination energy of Moscow 35 spring wheat seeds, white cabbage Number one mushroom 147 and White filling 241 increases respectively by: 14.1; 28.1 and 32.8%, and laboratory germination is increased by: 1.0; 8.2 and 3.2%.

Thus, the use of the claimed method of pre-sowing seed treatment of bluegrass, cabbage and nightshade crops, involving seed treatment with a 0.003% aqueous solution of tetrabornothiourea compounds, can significantly increase the germination energy and germination of seeds of bluegrass, cabbage and nightshade cultures, which accelerates the onset of ripening and leads to increase productivity.

Example 2. Stimulation of the growth of plants of cabbage, Number one mushroom 147 was carried out by pre-sowing seed treatment in a 0.003% aqueous solution of tetrabornothiourea compound.

Data on the effect of tetrabornothiourea compounds on the yield of early cabbage are given in table 2.

Example 3. Stimulation of tomato plants White filling 241 was carried out by pre-sowing seed treatment in a 0.003% aqueous solution of tetrabornothiourea compound. The results of the experiments are given in table.3.

Example 4. Stimulation of plant growth of Bordeaux 237 table beet was carried out by pre-sowing seed soaking in a 0.003% aqueous solution of tetrabornothiourea compound.

The results of the experiments are given in table.4.

From the data in Tables 2–4 it follows that when pre-sowing seed treatment for white cabbage No. 1 mushroom No. 147, White filling tomato 241 and Bordeaux beetroot 237, the yield increases, respectively: by 61.6; 40.9 and 62.4%.

Thus, the use of the claimed method of pre-sowing seed treatment of agricultural crops, involving seed treatment with a 0.003% aqueous solution of tetrabornothiourea compound, can significantly increase the yield of crops.
