Description
Technical Field
The utility model belongs to the technical field of the crop physiology, concretely relates to root exudates collects and allelopathy viewing device.
Background
Allelopathy refers to the chemo-ecological phenomenon in which a plant influences the growth and development of neighboring plants (including microorganisms) by releasing chemicals into the surrounding environment. Allelopathy is divided into the concept of allelopathy which is continuously expanded along with the continuous and deep research, and the allelopathy of plants is proposed to be the result of the interaction of plants and microorganisms, and comprises allelopathy (amensalom), autotoxicity (autotoxicity), autoimmunity (stimulation) and reciprocity (tolerance). In the agricultural ecosystem, the positive effect (positive effect) of allelochemicals is fully utilized, and the negative effect (negative effect) is avoided, so that the method plays an important role in establishing a sustainable agricultural system and Europe, and is considered as an important ecological agricultural technology. The main transmission routes of allelochemicals: (1) leaching, namely leaching the plant from the leaf surface of the plant, and washing the plant into soil by rainwater to play a role, wherein the leaching comprises sprinkling irrigation, rainwater, dew, mist and dense mist leaching; (2) volatilizing, namely volatilizing the plant body surface (stems, leaves and flowers) into the environment to play a role, wherein the plant body surface is mainly terpenoids; (3) root secretion; (4) decomposition (degradation) of litters (or rotting plant residues).
Root secretion is an important way for allelochemicals to play a role, and a large number of research reports related to plant rhizosphere in recent years reveal that many plants can release allelochemicals into soil through root secretion to inhibit the normal growth and development of adjacent homologous or heterologous plants. The inhibition effect on the same plants is the continuous cropping obstacle. Continuous cropping obstacles of many crops and decline of artificial forests are closely related to the presence of allelochemicals in root exudates. The continuous cropping obstacle is especially obvious in the planting of traditional Chinese medicinal plants using rhizomes as medicines, such as ginseng, salvia miltiorrhiza, rehmannia glutinosa, angelica, fritillaria, and the like. However, the absorption and utilization of the root exudates by the microorganisms in the soil, and the characteristics of complex components, low content, different types and quantities of the root exudates according to plant types and rhizosphere environments and the like of the root exudates make the root exudates difficult to effectively extract. In the current research, the means of collecting, separating, purifying and identifying the root exudates are various, and an authoritative, unified and effective method is lacked, so that the method is an international problem in the research of the root exudates and restricts the deep development of the related research field.
