Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a rice root growth configuration observation device. Background technique [0002] The root system of crops is the main organ for nutrient absorption and material exchange between crops and the soil. It is an important organ for crops to absorb nutrients, water and synthesize some endogenous hormones. It is the basis for the survival of crops aboveground. The morphological construction of aboveground organs is closely related to the yield of crops. The morphological and physiological characteristics of roots include root architecture, spatial level distribution, root length, root diameter, root volume, root activity, root absorption area, etc. Due to the natural growth of crops The root system has been deep underground for a long time, and there are many limiting factors for the in-depth study of the shape, configuration and physiological characteristics of the root system,...

[0002] The root system of crops is the main organ for nutrient absorption and material exchange between crops and the soil. It is an important organ for crops to absorb nutrients, water and synthesize some endogenous hormones. It is the basis for the survival of crops aboveground. The morphological construction of aboveground organs is closely related to the yield of crops. The morphological and physiological characteristics of roots include root architecture, spatial level distribution, root length, root diameter, root volume, root activity, root absorption area, etc. Due to the natural growth of crops The root system has been deep underground for a long time, and there are many limiting factors for the in-depth study of the shape, configuration and physiological characteristics of the root system, which makes it more difficult to accurately observe and study the root system. The main reason is that the sampling of the underground part of crops is limited. The workload is large, and it is difficult to ensure the integrity of the root system, which greatly increases the error of artificial sampling;

[0003] At present, the sampling methods in the study of rice root system include direct field sampling method, root bag method, rinsing method of potted plants, and direct sampling method under hydroponic conditions. These methods all have damage to the integrity of the root system and cannot perform well. It is difficult to obtain the real growth state of the root system under the field rice population, and it is difficult to observe the root structure. In order to obtain a complete root ecology of the rice field population, it is necessary to provide a method that can simulate the field population environment, which is convenient for root extraction and observation of root architecture. The device ensures the integrity of the sampling, thus ensuring the accuracy of the indicators related to the root morphology and physiological characteristics during the investigation
