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...

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.
