Abstract
The used seed protectants of agricultural crops, and in particular cotton, with a shortage of nitrogen fertilizers, do not provide plants with additional nitrogen in the required volume. In this article, the task is set to create an active and on its basis a perparativeform of a composition of multifunctional action, which allows simultaneously reducing diseases of cotton plants, increasing the accumulation of easily hydrolyzable nitrogen in the soil and obtaining a high yield of raw cotton.The purpose. Study of chemical interaction in a three-component water-salt system monomethylolourea (MMM) -molybdenum phytocomposition (FSMo) -water by visual-polythermal and isothermal methods. Objects. MMM, FSMo, double compound MMM•FSMo-active substance Results.The binary systems MMM–water and FSMo–water, which are part of the system under study, were studied from the complete freezing of thesystem -3.4÷45.4oC (MMM) and -1.3÷43.2oC (FSMo). The triple MMM–FSMo–water system was investigated at temperatures from -11.0 ÷40.0 oC, by six internal sections; of these, I-IV were carried out from the MMM–water side to the top of the molybdenum phytocomposition, and V-VI from the FSMo –water side to the top of the MMMformed in the temperature range -6.9÷35.2oC at a content of 3.7-38.3% MMM and 5.1-6.5% FSMo. Conclusion.Thus, by visual-polythermal and isothermal methods of physico-chemical analysis, the region of crystallization of a new double compound –an active substance based on monomethylolourea and a phyto-compound of molybdenum at a molar ratio of 1:1 has been established.
