Description

 Regularities of water exchange, water consumption and formation of productivity of agricultural crops in the conditions of irrigation are established. Prepared: the monograph "Water exchange and water consumption of crops under irrigation" and the scientific publication "Improved methods for calculating the total water consumption of plants under irrigation." Regularities of transpiration of tomato plants by phases of growth and development on soils of different particle size distribution depending on meteorological indicators are obtained. The dynamics and intensity of transpiration of plants during the day were determined. Transpiration coefficients, its intensity and productivity are calculated. It is statistically proven that the transpiration of tomatoes depends mostly on the deficit of humidity and solar radiation. A method for diagnosing watering periods using a phytomonitoring station has been developed. According to the main indicators of phytomonitoring of apricot and sweet cherry, the time of occurrence of water deficiency in the plant is established. The regularities of xylem flow index changes in tree trunks are revealed. A close correlation between the intensity of apricot and cherry leaf transpiration intensity and the daily value of the xylem flux index was statistically proven. On the basis of the established regularities of a functional condition of an apricot and a sweet cherry the method of management of parameters of a physiological condition of trees of fruit stone cultures and system of microirrigation is developed. According to the results of researches the regularity of change of transpiration of plants of valerian medicinal from meteorological elements is received. The transpiration coefficient and transpiration productivity of valerian plants were determined. The dependence of the intensity of transpiration of valerian plants on the average daily air temperature, relative humidity and water vapor pressure deficit was revealed.
