Sugarcane root system growth dynamic monitoring method

Abstract

The invention relates to a sugarcane root system growth dynamic monitoring method, and belongs to the sugarcane root system study technical field; the method comprises the following steps: trenching in a test field at least 6 months before the sugarcane is planted, placing Minirhizotron into the soil at a certain angle, evenly refilling the dug soil layer, and planting the sugarcane on the test field when the tube and the soil are in good contact; using a root system scan system to regularly watch the root system growth conditions and dynamic changes. The sugarcane root system growth dynamic monitoring method mainly comprises a Minirhizotron install method, the install number, the sugarcane plantation, and a sugarcane root system in situ observation method, thus studying the sugarcane rootsystem growth dynamic status, realizing harmless, fast and accurate monitoring and study of the sugarcane root system growth dynamic and form parameters, and providing a harmless, in situ monitoring,efficient and reliable study means for the sugarcane root system study.

Description

technical field [0001] The invention belongs to the technical field of sugarcane root system research, and in particular relates to a method for monitoring the growth dynamics of sugarcane root system. Background technique [0002] The root system has an important influence on the growth and development of plants. Scientific understanding, research and mastery of the growth dynamics and morphological distribution of the sugarcane root system have important scientific guiding significance for the development of sugarcane production and variety selection. [0003] At present, the research on the root system of field crops in my country mainly adopts the excavation method. Micro-root canal is a non-destructive field test method to observe root growth dynamics. In recent years, many units in China have introduced micro-root canal technology from abroad, but there are still many difficulties in how to accurately apply this technology, especially on sugarcane , especially the ins...

Micro-root canal is a non-destructive field test method to observe root growth dynamics. In recent years, many units in China have introduced micro-root canal technology from abroad, but there are still many difficulties in how to accurately apply this technology, especially on sugarcane , especially the installation method, installation quantity and monitoring cycle of the micro-root canal have a great influence on the monitoring of the sugarcane root system. 1-2mm), and reach a certain depth, and then insert the micro-root canal into the hole. It is difficult to select a suitable drilling tool for this method, and there are gaps in the contact between the tube wall and the soil, and the micro-root canal is easy to loosen, affecting Root growth, the root system is easy to grow in the gap or along the pipe wall, on the other hand, the drilling hole is greatly affected by the soil texture, if the soil texture is hard and contains stones, dry clay soil or loose and unstructured soil There are many problems with root canals, drilling holes in wet clay soil, when the wet clay dries, cracks are formed, light can enter the soil or micro root canals, in soil with stones, the canal walls are easily scratched or scratched On the other hand, the installation angle and position of microroot canals, monitoring time intervals and sugarcane planting methods also affect the quality of root growth monitoring and the accuracy of data.
