A method for monitoring sugarcane root growth dynamics

Abstract

The invention relates to a method for monitoring the growth dynamics of sugarcane root systems, belonging to the technical field of sugarcane root system research. The method is at least 6 months before sugarcane planting, ditches the microroot tubes into the soil at a certain angle, and backfills them evenly with the excavated soil layer, and plant sugarcane on the test site after the tubes are in good contact with the soil , and then use the root scanning system to regularly observe the root growth status and dynamic changes. The method for monitoring the growth dynamics of sugarcane roots provided by the present invention mainly includes the installation method of microroot canals, the number of installations, the planting of sugarcane and the in-situ observation method of sugarcane roots, so as to study the dynamic conditions of sugarcane root growth and realize the monitoring of sugarcane root growth. The non-invasive, rapid and accurate monitoring and research of dynamic and morphological parameters provides a non-invasive, in-situ monitoring, efficient and reliable research method for sugarcane root research.

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...
