Corn roots space-time structure measuring device

Abstract

The invention belongs to the measuring technical field of plant root system structure and relates to a detecting device for corn root system structure, which includes two parts like a round barrel and a root system supporter. The round barrel is composed of a round barrel body and a barrel bottom. The root system supporter is composed of a round layer mesh and a layer mesh supporter. The root system supporter is arranged in the inner part of the round barrel and a clearance is reserved between the root system supporter and the round barrel. The body of the round barrel is fixed with the barrel bottom. The barrel bottom is a cylinder and provided with a permeable hole. The layer mesh and the layer mesh supporter of the root system supporter are fixed together. The layer mesh supporter leads the arrangement of the layer mesh to be fixed and maintain an invariable shape. In order to keep the natural situation for the growing of corn root system, the structure of the layer mesh is in gridding shape. The invention can not only accurately detect the quantized indexes changed with the time process of the corn root system, such as the fresh weight, dry weight, length and size of the root system, etc., but also can accurately and conveniently detect the space structure of the whole corn root system. The whole device has the advantages of simple structure, convenient operation as well as accurate and reliable result.

Description

technical field

[0001] The invention belongs to the technical field of plant root structure measurement, and relates to a device for measuring the structure and time distribution of plant roots, in particular to a corn root structure measurement device. Through this device, a whole picture of the temporal and spatial structure of the corn root system can be presented as a whole. Background technique

[0002] Most of the corn root system grows in the soil. To scientifically understand corn production, it is necessary to fully understand the growth of the corn root system and the distribution of root groups, effectively control the relationship between the root system and the aboveground part and the root system’s water and nutrient utilization efficiency, and achieve corn production. The purpose of high yield, high quality and high efficiency. At present, researchers generally use indoor sand culture, hydroponics or dig cylindrical regular soil pits in the field, put linoleu...
