Improving the elements of organic farming in rice cultivation

Abstract

The guarantee of food security of any state is to obtain guaranteed yields of high-quality agricultural products. The implementation of such a task is feasible only if all the technological and environmental conditions of its cultivation are met. In the current situation, when, along with the growing anthropogenic load on the land of the agricultural Fund and the reduction of available irrigation water, as well as non-compliance with agricultural production technologies, organic farming is the solution to the urgent problem of obtaining high yields of high-quality products without compromising the agricultural resource potential of soils. The transfer of production to organic farming should be carried out in stages, due to the high cost of its implementation and the use of a large number of additional resources (agro-reclamation, economic, energy, labor, technical and technological, environmental). In our research, we suggest using an organic method for cleaning drainage runoff with halophytes planted in phyto-sections located in the discharge channels of the rice irrigation system. It was found that the use of phyto-sections of various lengths, depending on the chemical composition of drainage and discharge waters, allows one to clean the drainage runoff from mechanical impurities, organic and biogenic elements. This makes it possible to reduce suffusion and removal of nutrients from rice checks, reduce the irrigation rate by 10%, increase the reclamation state of soils, and reduce the cost of rice production by 7%.
