The influence of the main types of chemistry and the degree of salinity of soils and man-made soils on the germination of phytomeliorant seeds

Abstract. The purpose and objectives of the study is to establish levels influence chemistry degree salinity on onset half (LD50) full (LD99) death seeds alfalfa blue hybrid yellow clover. To identify participation each factor in legume using correlation coefficient determination. conduct a comparative assessment salt resistance sweet clover alfalfa. Methods. main natural types salinization characteristic forest-steppe zone Western Siberia are selected as objects study. germination energy were determined according GOST 12038-84. Model variants solutions for created taking into account proportions formation salinization. represented by sulfate-soda, sulfate-chloride (neutral), gypsum chloride-sulfate salt. Scientific novelty. Drilling slurries stored barns during extraction hydrocarbon raw materials correspond similar conditions. Artificial water-salt with given concentration made it possible complete at appropriate level Comparison neutral sulfate-soda showed that presence soda solution determines its toxicity 86–87 %. negative effect appears greater extent due an increase osmotic pressure. nutrient saline reduced phytomeliorant crops 1.9–2.5 times. Results. It has been established under conditions salinization, plants experience acute deficiency calcium. introduction chemical reclamation pans drilling eliminates this deficiency. establishment indicators allows you adjust seeding rate phytomeliorants. indicator indicates expediency applying slurries.
