Description
Technical field
The present invention relates to a kind of air-breather, be specifically related to a kind of root system of plant air-breather of breathing freely for root system of plant in soil and utilize this device to carry out the method for root system of plant ventilation.
Background technology
Plant is in process of growth, the growth of root system plays an important role for the growth of plant itself, root growth is except the nutrient needing soil to provide sufficient, oxygen needed for the breathing of its root cell is also provided by the air be dissolved in soil, therefore, the aeration status of soil usually plays a part key for the growth of plant.In order to allow root system of plant be grown preferably, namely existing promotion root system of plant Growth of Cells divides except using the modulator effects such as plant establishment agent, can also adopt the mode punched in the soil place near root system of plant.Above-mentioned soil place punching near root system of plant, what not only can make that air can be more is dissolved in soil, so that the respiration of root cell; In addition, the heat that root system of plant cell can also produce because of respiration by the hole near root system on soil and carbonic acid gas enter in air, reduce the temperature of root system surrounding soil.Therefore, near root system of plant, the punching of soil place can provide good permeation functions to the growth of plant.But the mode of above-mentioned traditional soil place near root system of plant punching wastes time and energy; No matter soil place is artificial or the hole got of machinery all can seal because of soil cause loosely itself over time near root system, so just needs again to punch, thus cause repeating of work, compare and waste time and energy.Another mode is first with machine or Manual punching, then is inserted in soil by the pipeline of hollow, utilizes the through hole of pipeline side to provide good permeation functions for root system of plant; The method is simple to operate, only need ventilative pipeline to insert the soil after punching, but the pipeline of above-mentioned hollow can be covered by dead leaf, deadwood gradually, or be blocked by sandy soil and other foreign material, or by rainwater embedding, cause the root system of plant still can not carry out good ventilation.A kind of mode is also had to be add ventilating cover at the pipeline of above-mentioned hollow, although ventilating cover can alleviate the phenomenon of sandy soil blocking pipe, but dead leaf, deadwood and other foreign material still can cover ventilating cover, or tiny sandy soil or rainwater still can enter pipeline and then blocking pipe by the aperture of ventilating cover, the hollow pipeline adding ventilating cover still can not make root system ventilate well.
Summary of the invention
For the problems referred to above, the technical problem that the present invention mainly solves is to provide a kind of root system of plant air-breather and vent method, described root system of plant air-breather not only can avoid breather line by dead leaf, deadwood, sandy soil, rainwater and the blocking of other foreign material, and can make to form cross-ventilation around root system of plant soil, both for root system of plant cell respiration provides sufficient oxygen, immediately heat and the carbonic acid gas of root system of plant cell respiration generation can be discharged again, promote the growth of root system of plant, and then promote the growth of plant, this root system of plant air-breather and vent method are particularly useful for the transplanting of trees, greatly can improve the survival rate of transplanting trees, also can be used for the cultivation of wetland plant.
