СОВРЕМЕННЫЕ БИОПРЕПАРАТЫ ДЛЯ ТВЕРДОСЕМЯННЫХ КУЛЬТУР

Abstract

One of the significant factors of increasing the yield of agricultural crops is the use of fertilizers and pesticides. However, the use of chemicals causes environmental pollution and is accompanied by significant investments of material and energy resources. In addition, there is a decrease in humus in the soil. Therefore, agrotechnical techniques aimed at maintaining the natural fertility of the soil and stimulating the development of soil microflora are very relevant. Currently, natural growth regulators and bacterial preparations designed to activate the metabolic processes of plants and increase their productivity are increasingly used in crop production. Biological products can affect plants at different stages of growth and development. But their influence is most effectively manifested in the process of seed treatment before sowing. Such seeds have a high plasticity to changes in environmental conditions. And the use of drugs has a multifunctional effect. The article presents research materials on the effectiveness of the use of a new-generation biological product and micro-fertilizer, as well as zeolite-containing clays as a pre-sowing treatment of clover seeds. We used "Albit "(a complex biological product), "Polydon Bio Bean" (micro-fertilizer) and a mixture of rhizotorphin with "Alanite" (zeolite-containing clay). The results of the conducted studies revealed differences in the germination energy and germination of seeds of different types of clover. The influence of meteorological conditions and ecological and geographical origin on hard - seeding is determined. The seeds were treated with rhizotorphin and thiamine. Various doses of Alanite were tested in a mixture with risotorphin. The best option is a mixture of 1:5, which increased germination (37%), seed productivity (84%) and nitrogen-fixing ability. Both drugs had a stimulating effect on the germination energy and seed germination (15 – 28%). The acceleration of the development phases, an increase in the number of generative stems, the number of inflorescences, and foliage were noted. The yield of green mass for 2 mowing increased by 130 c/ha. The qualitative composition of the feed mass has also improved.
