Currently, in the agricultural sector of the South of Russia, unfavorable natural, climatic and technogenic conditions are developing for the production of agricultural products, especially resource-intensive crops, one of which is rice. The shortage of fresh water observed in recent years poses a difficult task for the workers of the agro-industrial complex to develop and implement resource-saving technologies in the conditions of extreme deterioration of the facilities of the water management complex of the Lower Kuban and more frequent climatic anomalies. One of the solutions to this situation is the development of nature-like technologies. The goal of nature-like technologies is to minimize the anthropogenic impact on agricultural land, reduce resource intensity and increase the environmental friendliness of agricultural production. The article presents the results of the development of rice maps of a new generation on resource-saving rice production technology based on nature-like technologies. The introduction of nature-like technologies in rice irrigation systems will increase the productivity of rice crops by 20-25% relative to traditional methods of rice cultivation, with a reduction in irrigation rates by 45-60%. Based on the theoretical studies obtained, a computational experiment and a study in laboratory and experimental field conditions of quantitative relationships between parameters and factors affecting the rice production process in the South of Russia, it is proposed to develop a new methodology for increasing the productivity of rice cultivation, expanding the understanding of the integrated use of rice irrigation systems, based on which requires the use of mathematical models (a mathematical model of the functioning of rice agricultural landscapes, a mathematical model of the process of pollution of drainage and waste water in rice irrigation systems) and resource-saving technologies for rice cultivation.
