Description
Technical Field
The invention belongs to the field of root system technical research, and relates to a full root system collection method for straight and deep root system plants.
Background
The root system is an important nutritive organ for plants to absorb water and nutrients and is also a main organ for the plants to exchange substances and energy with the soil environment, and the morphological structure and the physiological characteristics of the root system can reflect the ecological adaptation of the root system to the environment. The morphological structure and physiological characteristics of the root system are closely related to the absorption of nutrients and water, and the morphological structure and configuration of the root system are important indexes of the utilization efficiency of the water and the nutrients of the plant. The fine roots are important components of plant root systems and have important physiological and ecological characteristics. The thin roots are most actively metabolized physiologically and are most responsive to the environment. The fine roots have extremely large surface area and are the main organs for plants to absorb nutrients and water. Therefore, the research on the morphological structure and physiological characteristics of the plant root system has become an important content of the research on the utilization efficiency of resources such as plant nutrition efficiency, water efficiency and the like, and is also a hot spot of the research on plant physiological ecology. The growth and development of the root system can be quantitatively described by knowing the morphological and structural characteristics of the root system. However, the plant roots grow underground and cannot be visually seen by eyes, and the common excavation method is not easy to excavate all the roots of one plant, so that the structure of the plant is difficult to understand and study. The method can overcome the difficulties and easily obtain all root systems of the straight root plants.
So far, chinese patent (CN 106197286 a) discloses a method for measuring the shape of a fibrous root system, and particularly relates to a method for measuring the shape of a fibrous root system. There is no teaching on how to obtain a complete root system at the early stage and how to obtain the root system. The method belongs to plants with longer root systems, the length of the root system of a seedling is more than one meter, and for the root system, how to obtain a complete root system is a difficult problem in researching the root system. Chinese patent (CN 206459848U) discloses a root system collecting device for a fibrous root system plant, which is composed of a nail plate, a sample removing plate and a sample cutting device, and is a good method for a relatively shallow fibrous root system, but the problem that a straight-root deep root system can not obtain a complete root system is solved. Therefore, aiming at the characteristics of deep roots, the invention provides a full root system collection method of straight deep root system plants, which is favorable for completing the measurement of morphological indexes such as grading and parting structure morphological indexes of roots of the root system, the length of the root system, the diameter and the like and the recognition of the whole root system.
