Description

The invention relates to the field of agriculture, in particular to a method for growing flax, and can be used in farms cultivating flax for seeds and fiber.

A known method of growing flax flax, which consists in treating flax flax seeds with a biological product Binoram, consisting of a mixture of suspensions of strains of Pseudomonas specias 7G, 7G2K and 17-2, taken in a ratio of 1: 2: 1 with a concentration of (2-2.5) × 10 10 cells / ml, while seed treatment before planting is carried out at the rate of 50-100 ml of suspension per ton of seeds at a rate of working solution consumption of 10 l / t of flax cultivation with seed treatment with Binoram / 1 / biological product.

A known method of cultivating flax flax / 2 /. The method involves the use as a fertilizer of a fine powder of silicon dioxide, which is mixed with seeds before planting.

The disadvantage of the described methods is their one-sided effect on the plant. In the case of the use of the drug Binoram with seeds, fertilizer is not applied, and when using fine powder of silicon dioxide, a weak stimulating effect is manifested. It should also be noted that in certain years or under certain conditions (drought, cold snap), the strains of the microorganisms that make up the Binoram biological product may be inactive or die. Silicon as a fertilizer may not be effective if the soil contains enough of this element.

A known method of growing flax flax / 3 /, taken as a prototype, including pre-sowing seed treatment with a solution of boric acid, prepared at the rate of 5-12 l of water, into which dry boric acid is added in an amount of 1.25-1.50 kg per 1 ton seed. Get a solution of boric acid with a concentration of 10-30%.

The disadvantage of the prototype is that the described method does not have the necessary complex effects on the growth and development of flax.

The invention is aimed at eliminating these disadvantages and consists in the fact that the method includes pre-sowing treatment of flax seeds with a tool containing 10-13% boric acid and 0.005-0.0005% humic plant growth stimulator obtained by alkaline hydrolysis of lowland peat with an aqueous solution of ammonia in the presence of hydrogen peroxide. Moreover, the dose of the seed treatment is 5-12 liters per 1 ton of flax seeds.

The claimed invention differs from the prototype in that the pre-sowing treatment of flaxseed seeds is carried out by means containing not only boric acid, as in the prototype, but also a humic plant growth stimulator obtained by alkaline hydrolysis of lowland peat with aqueous ammonia in the presence of hydrogen peroxide at a concentration of 0.005- 0,0005%. Seed treatment with this product provides a higher yield of seeds and straws of flax.

New in the claimed invention is the combined use of boric acid and a humic plant growth stimulator from peat for the treatment of flax seeds. The combined use of these components in the tool used in the inventive method, increases their field germination, accelerates the growth and development of flax, significantly increases the seed productivity and yield of flax straw.

Separate use of boric acid and a humic stimulator of plant growth from peat provides a slight increase in the yield of seeds and straws of flax. The combined use of boric acid and a humic plant growth stimulator from peat in the composition of the agent used in the present method allows to obtain an effect higher than their separate action.

The following is an example of obtaining a concentrated stock solution of humic plant growth stimulator from lowland peat.

Example 1: 1000 g of sedge peat with a humidity of 60% are loaded into an autoclave, 3200 ml of water, 100 ml of a 25% solution of ammonia and 100 ml of a 30% solution of hydrogen peroxide are added. The mixture is stirred. The autoclave is closed and turned on. Further processing is carried out at 120 ° C for four hours with constant stirring. The resulting suspension is separated by centrifugation.

The liquid phase after centrifugation is a concentrated mother liquor containing 4.5% humic acids. The resulting mother liquor is diluted with distilled or drinking water 4.5 times and get a solution containing 1% humic acid, which is used to obtain the funds used in the inventive method for growing flax.

Example 2: To treat 1 ton of flaxseed seeds, 60 ml of a 1% solution of the humic plant growth stimulator obtained in Example 1 are mixed with 1.2 kg of boric acid and 12 liters of water. The mixture is thoroughly mixed. The resulting product contains 0.005% of humic acids and 10% of boric acid.

Other examples of obtaining funds used in the claimed method of growing flax flax are presented in table 1.

The effectiveness of the proposed method for growing flax flax is confirmed by the results of field experiments, presented in table 2. The repetition of each option is fourfold.

The invention allowed to increase, compared with the control, up to 15% seed yield and up to 22% straw flax. Compared with the prototype, straw yields increased by 26-28%, flax seeds by 1-2.5%. Given the high cost of straws, the proposed method of growing flax flax will provide a significant economic effect.

The use of a method containing boric acid and a humic stimulator of plant growth from peat / 4 / in a method for growing flax flax for seed treatment makes it possible to add the required dose of boron microelement with seeds, significantly stimulate plant growth and development, which ensures an increase in seed and flax yield straws.

The invention improves the yield of seeds and straws of flax flax, provides environmental safety and high economic efficiency of production, plant resistance to adverse conditions.
