Slope plant root system architecture regulation system and method

Abstract

The invention discloses a slope plant root system architecture regulation system and method. The system comprises a nutrient dispenser, a reservoir, a drip irrigation controller, a water delivery pipeand water guide devices. The water guide devices are arranged in parallel and connected with the water delivery pipe, an inlet of the water delivery pipe communicates with the drip irrigation controller, an input end of the drip irrigation controller is connected with the reservoir, and the reservoir is externally connected with the nutrient dispenser. Each water guide device comprises a water guide pipe and a water blocking device, wherein a drainage channel is arranged in the water guide pipe; a moisture and nutrient induction layer is arranged on the water guide pipe to divide the pipe wall of the water guide pipe into a plurality of water seepage units, and each water seepage unit is provided with a plurality of water seepage holes; and a water blocking head of the water blocking device can move in the axial direction of the water guide pipe, and the drainage channel is controlled to realize communication with different water seepage units so as to realize drip irrigation of soilat different depths. The regulation system calculates the number and growth angle of root systems required for slope reinforcement according to a theory, locally changes the moisture content and nutrient content of soil near the root systems, induces the root systems to grow in a desired direction, and improves the soil fixation capacity of the root systems.

Description

technical field [0001] The invention belongs to the technical field of ecological slope protection, and in particular relates to a system and a method for regulating the root system configuration of slope land plants. Background technique [0002] Plant slope protection technology, as a new type of ecological technology, has been widely used and recognized all over the world. However, the growth of plant roots is gravitational. For example, the commonly used slope protection plant vetiver has extremely developed root system, which can generally grow to 2-3m, and the deepest can reach 5-6m. However, its root system grows vertically downward concentratedly in the slope soil, while the root system perpendicular to the inward slope is short and few. This root system configuration cannot maximize the soil-fixing ability of the root system. Contents of the invention [0003] The purpose of the present invention is to provide a control system and method that is beneficial to imp...
