4 I.1. The invention is related to agriculture and can be used in seed production and breeding for the cultivation of seeds. .. There is a known method of preparing seeds for planting by applying a coating of lowland peat and mineral fertilizers to the Scientific Research Institute of Water Resources. A non-phosphatom of the known method is a low final moisture content of the peat-mineral shell. For planting potatoes it is not. It is permissible, since in the storage of the finished planting material, the peat-shaped shell absorbs moisture from the nutrients of the tuber itself — potatoes — dissolved in it, which ultimately leads to the death of embryos or the appearance of frail sparse shoots and a significant decrease in yield. Besides, the method obtained by a known method of peat-mineral1} and the shell contains an insufficient amount of nutrients. A method of preparing seed potatoes for planting is known, which includes the covering of the seed with peat-mineralized nutrient mixture containing organic matter and mineral components of the following composition May.%. peat (5-20% decomposition degree 60-80, peat (30-55% decomposition degree; 18-36, urea 0.5-1 superphosphate 0.6-1.3, and potassium chloride 0.7 -1.5 .2 J. The disadvantage of this method is “not enough assimilating The purpose of the invention is to increase the nutrient absorption of seed shells. This goal is achieved in that according to the method of preparing seed potatoes for planting, which includes enveloping the seed with a rhomineral mixture containing an organic binder and The mineral components, the peat-mineral nutrient mixture, before coating the seeds, are treated with j-radiation at an irradiation dose of 1-2 Mrad. Irradiation by a stream of / 3 particles leads, obviously, to the destruction of organic matter. peat substances, as this increases the amount of water1. pacTBOpHMbtx, easily hydrolysable humic ireductifying substances, which are valuable nutrients and are easily absorbed by plants. In addition, during the treatment of β-radiation, the radiolysis of potassium chloride with atomic chlorine is possible. As a result of the interaction of active atomic chlorine with peat, chloromates are formed, which are biologically active substances and, when introduced into the soil, accelerate the growth and development of plants. P PI and me R 1. Potato tubers are cut into A parts, after which a peat-feed mixture is prepared, consisting of the following components (on a dry substance of the shell) wt.%: Peat (15% decomposition degree) 70, peat (40% decomposition degree) 26.9, carbamide 0.9, superphosphate 1.0,. potassium chloride 1,2.-The prepared mass is processed accelerated. electrons on an experimental electron accelerator of the type ILU-6 with a dosage of radiation from 0.7 to 0.5 Mrad, moistened by adding 70% water to dry weight, applied to potato tuber particles to obtain a spherical planting material and dried up to a humidity of 30-40% at a material temperature of 40-42 ° C V for 20-24 hours. Planting material is ready for use. As a control, particles of potato tubers covered were used. peat mineral mixture of the above composition, not treated with radiation. In addition, unskilled potato particles were used in field experiments for comparison. When these particles were planted, the organic-mineral components included in the envelope were locally introduced. The results of testing the treatment of seed potatoes, as well as the group composition of the processed and untreated radiation, the peat-shell of potato particles and the yield of potatoes (variety Mid-Ripe Spark) in preparing seed potatoes for planting by the proposed and known methods are shown in the table.

As can be seen from the table, the irradiation of the peat-mineral mixture before applying it to potato particles contributes to an increase in the content of nutrients {easily digestible organic crops. As a result of the introduction. yo, sadog y, material .with pre-irradiation, oh The peat-mineral peat box gives a statistically reliable

yield increase potatoes. The optimal dose should be considered: 1-2 Mrad. At lower doses of irradiation, the yield increase is significant and does not exceed the magnitude of the smallest significant difference (HCP). Higher (more than 2 Mrad) Doses of irradiation are not unprofitable due to the insignificant expenditure of energy with an insignificant increase in yield.
