Abstract
1. Способ контроля воздушного режима в корнеобитаемой среде, заключающийся в контроле воздухоемкости и воздухопроницаемости среды, отличающийся тем, что основу для контроля и воздухоемкости, и воздухопроницаемости составляет физический процесс установления газового равновесия в отношении индикаторного газа (метана) между воздухом в свободном поровом пространстве корнеобитаемой среды и наружным воздухом в итоге диффузионного перераспределения дозированного импульсным образом в наружный воздух количества молекул этого газа из наружной воздушной среды в свободное поровое пространство при сохранении постоянным общего количества молекул индикаторного газа в общем герметично изолированном воздушном пространстве двух контактирующих воздушных сред с определением воздухоемкости исходя из условия, что доза метана распределяется между этими средами по завершении процесса выравнивания пропорционально их воздушным объемам, а воздухопроницаемость определяется по времени выравнивания. ! 2. Устройство контроля воздушного режима в корнеобитаемой среде, состоящее из: герметичной камеры с размещаемым внутри испытуемым образцом, импульсного дозатора метана и ИК-газоанализатора метана, соединенных с камерой в общий герметичный замкнутый воздушный контур, по которому с помощью вентилятора циркулирует воздух, поступающий в камеру и забираемый из нее через воздухораспределительные устройства. ! 3. Устройство по п.2, отличающееся тем, что в состав устройства дополнительно включаются без нарушения герметичности замкнутого воздушного контура приспособления, регулирующие состояние воздушной среды в герметично 1. A method of controlling the air regime in a root-inhabited medium, which consists in controlling the air volume and air permeability of the medium, characterized in that the basis for controlling both air volume and air permeability is the physical process of establishing gas equilibrium with respect to the indicator gas (methane) between air in the free pore space of the root environment and outside air as a result of diffusion redistribution of the quantity of molecules of this gas dosed in a pulsed manner into outside air from outside air into the free pore space while keeping the total number of indicator gas molecules in the total hermetically isolated air space of two contacting air media constant with the determination of air capacity based on the condition that the dose of methane is distributed between these media at the end of the leveling process in proportion to their air volumes and air permeability determined by the alignment time. ! 2. A device for monitoring the air regime in the root habitat, consisting of: a sealed chamber with a test sample placed inside, a pulsed methane dosing device and an IR methane gas analyzer connected to the chamber into a common sealed closed air circuit, through which air enters chamber and taken out of it through air distribution devices. ! 3. The device according to claim 2, characterized in that the device is additionally included without compromising the tightness of the closed air circuit devices that regulate the state of the air in a sealed
