Water regimes of rice fields

Abstract

The article is a review work, periodic moistening - a layer of water is absent throughout the entire growing season of rice, optimum soil moisture is created through periodic irrigation. Mostly applied permanent and shortened flooding. The most promising is the water regime with shortened flooding. Depending on the method of sowing, debris from the rice field by grasslands and soil salinization, there are various options for this mode. Rice plant, like any other, imposes different requirements for water in different phases of the growing season. The best medium for rice in the period of germination and in the phase of emergence is a moist soil. To obtain seedlings on highly saline soils with a close level of saline groundwater, the most favorable is a small layer of water, which is periodically replaced.
