Агротехника томатов в условиях управляемой системы ведения сельского хозяйства

Abstract

The aim of the work is to assess the impact of resource-saving irrigation technologies on water consumption, excavation depth, degree of salinity, duration of the light period, crop density and temperature changes when growing tomato in a managed farming system. The subject of the study is the factors affecting of the Lamia F1 variety tomato yield and water consumption (irrigation rate, soil salinity, excavation depth, duration of the light period, seedling density, temperature changes). Research objectives: to study the influence of managed farming system indicators (light period duration, greenhouse depth, seedling stem thickness, difference between day and night temperatures, salinity degree, irrigation rate) on tomato yield and seasonal irrigation rate; conducting experiments with fractional factorization of tomato yields and seasonal irrigation rates in accordance with managed farming system; development of an irrigation regime for the Lamia F1 variety of tomato culture according to the FAO method for managed farming system conditions; mathematical modeling of the dynamics of soil moisture, the consumption of nutrients when growing tomato crops under managed farming system conditions. The effect of the seasonal irrigation norm, the degree of soil salinity, the depth of the greenhouse, the length of the light period, the thickness of the stem of tomato seedlings, the difference between the maximum and minimum temperatures on the tomato yield of is substantiated; an irrigation regime for tomato crops has been developed based on the FAO method, taking into account managed farming system indicators; mathematical models of thermal regime processes, soil moisture dynamics, nutrient consumption in tomato cultivation under managed farming system conditions have been developed.
