Description

The invention relates to agriculture, and in particular to methods of presowing treatment of beet seeds.

A known method of treating sugar beet seeds (RU, patent 2161392, 2001), according to which the seeds are soaked for 12-18 hours in an aqueous solution of potassium hydroxide with a concentration of 0.01-1.0% and a working solution consumption of 3 l per 1 kg of seeds .

The closest analogue of the claimed method can be recognized as a method of processing vegetable seeds, according to which tomato seeds were soaked for 24 hours in a solution of sodium humate, yvin, hydrogen peroxide with a ratio of seed weight to solution 1: 2 (G. Kunavin. Use of growth regulators when tomato growing // Siberian Bulletin of Agricultural Science. - 1993. - No. 4. - S.3-7).

The disadvantages of the known methods are low efficiency in accelerating seed germination and reducing the content of nitrites.

The technical problem solved by the present invention is to develop a method of pre-sowing treatment of beet seeds, which provides increased germination of seeds, accelerated germination, increased yield and reduced nitrate content.

The technical result obtained by the implementation of the claimed method consists in increasing the efficiency of pre-sowing treatment of seeds by soaking them in a solution of a growth stimulator.

To achieve the specified technical result, it is proposed to use a method of pre-sowing seed treatment, including soaking the seeds for 12-18 hours in a solution of a growth stimulator, and a 0.15-0.20% aqueous solution of zoohumin is used as a stimulator. Zoogumin is made by soaking 250 g of zoogumus (TU 9292-001-00493391-94) in 1 liter of a 5% hydrogen peroxide solution for 48 hours at a temperature of 18-20 ° C, followed by filtration. 75 g of urea are added per liter.

The method of processing beet seeds is as follows: beet seeds are soaked in a 0.05-0.25% zoogumin solution for 12-18 hours, dried and sown in the soil.

Tables 1-3 show the results of experiments on seed treatment with various solution concentrations, with different exposures, and yield data.

Thus, when using the proposed method of presowing treatment of beet seeds, the germination energy increases and amounts to 82-83%, laboratory germination - 93-94%, field germination - 78-79%, the period from sowing to seedlings is reduced and is 9 days. Productivity increases to 35.3 t / ha, the mass of root crops reaches 315 g, the nitrate content decreases to 116 mg / kg of wet weight.
