Description
Technical field
The present invention relates to plant root growth field of measuring technique, more specifically relate to a kind of root system of plant visual monitoring analytic system and monitoring method thereof.
Background technology
For a long time, botanist divides the regulation and control of structure, function and the leaf photosystem of organ to carry out a large amount of research to plant shoot, has obtained significant progress.But due to the reason such as research method and condition of work, the research of below root system is lagged far behind to aerial part.Root system of plant is carried out to form structure, physiological property, the ecotype and interracial difference and environmental factor etc. that visual monitoring analysis is convenient to root system the impact of root system is carried out to deep research, research to root water uptake mechanism simultaneously, and theorize, half theory and semiempirical and empirical model describe root water uptake situation and be significant.According to the critical data of root growth situation, the method that can realize for working out plant maintenance optimum growh state provides experiment parameter and means.
At present, the method for the observation plant root growth situation generally adopting mainly comprises three kinds: douche, root case method, tank farming, but all there is corresponding defect in these three kinds of methods.
Douche is to dig out after the whole soil body that comprises root system of plant in field, and the soil body is packed in special wire netting elutriation apparatus, carefully root system is separated with grogs with jet tap water, until root mud separates completely, till obtaining entity root system.The Dittmerk of Iowa university of the U.S. adopts and studies in this way rye root system and obtained a large amount of valuable observation datas.The disadvantage of douche, the one, easily cause damage root, particularly the loss of the great-hearted young root of tool; The 2nd, be difficult to distinguish the root alive and dead root of plant, sometimes may also contain the root of weeds and other plant, and be difficult for obtaining complete root system and obtain reliable data.
Root case method is to contain native cultivated plant to replace Field observation with container, allows root system grow in the container more much smaller than field.In the time that needs are observed, opaque containers can be removed, again put again after to be observed.Because the trend moving direction main and moisture of root in container is consistent, thereby in basin with holes, root can be concentrated in basin edge and bottom outlet soil body place, and in the closely knit basin of atresia, root system is mainly concentrated in the soil body at basin edge.Its advantage is that basin is easy to move, and is suitable for adopting multiple great soil group simultaneously and different disposal is set, and under non-interfering condition, root growth is studied.The disadvantage that adopts this method is the restriction of the easy receptor of growth of root system, and in addition, the shortcoming of this method is to be difficult to carry out soil, root separation.
Soilless culture is that planting is included in the nutrient solution of the essential nutritional labeling of plant being provided with solid support device, or is planted in and infiltrates in the inert base that has the essential nutrient solution of plant.Adopt in this way and must carry out strict sterilization to all apparatus in advance, according to tree species collocation nutrient solution, and solve oxygen supply problem.The outstanding advantages of adopting is in this way can avoid loaded down with trivial details root, native lock out operation, but observe in this way the actual upgrowth situation difference of upgrowth situation and field of root system larger.
In a word, in root system of plant observation technology, there is easily injury root system of plant and spoiled soil structure in prior art, is difficult for realizing root soil and separates, and cannot observe the whole growth cycle of root system of plant real-time, dynamic, round-the-clockly and obtain data reliably.
