According to long-term studies of the influence of rice cultivation show that meadow-black soil, meadow, alluvial, meadow-swamp (heavy black soils) soils of the reclamation and water management complex of the Lower Kuban, with the beginning of their use for rice cultivation, lose their favorable physical properties and become degraded, merged, viscous and gleyed formations, which leads to a decrease in the yield and quality of the resulting grain, loss of soil fertility, as a rule, with the subsequent withdrawal of lands from the irrigation fund. In order to prevent these negative consequences, it is necessary to use the accumulated world experience of rice cultivation in a timely manner. For a number of reasons, many scientific achievements in the field of selective breeding and rice production technologies remain unpopular. Today, the level of information technology allows studying the advanced experience of rice cultivation in a short time. The world leader in rice production is the PRC, where for more than 10 years they have been practicing the cultivation of rice using drip watering under mulching film, considering this method to be one of the most effective and resource-saving. However, the rice-growing regions of the PRC are located in subtropical and tropical climates with the sum of active temperatures and solar activity during the growing season significantly exceeding the average values of these values for the rice-growing regions of the reclamation and water management complex of the Lower Kuban. Consequently, to implement this technology on the rice irrigation systems of the Krasnodar Territory, it is necessary to adapt them to the natural and climatic conditions of the region. Therefore, the paper proposes the technology of underground drip watering of rice, the introduction of which has proven its effectiveness and feasibility. |
