Mobile phenotypic cabin for acquiring and analyzing phenotypes of field crops

Abstract

The invention discloses a mobile phenotypic cabin for acquiring and analyzing phenotypes of field crops. The mobile phenotypic cabin comprises a root system monitoring system, a phenotypic cabin framesystem, an environment control system and a data acquisition system. An operating mechanism is arranged on the phenotypic cabin frame system, so that the phenotypic cabin can move back and forth on afield to a proper position, and contrast experiments of different environmental factors are carried out on the field under the same external soil hydrological environment. In the experiment process,an internal environment of the phenotypic cabin frame system can be set to be closed and controllable through a water sealing device, so that the adjustment of environmental factors in the cabin is more accurate, the phenotypic characteristic observation of indoor and outdoor plants can be realized, and the phenotypic characteristic acquisition of overground and underground plants is realized. Dueto the fact that field crop samples are rich, high-throughput, high-precision, low-cost and comprehensive phenotypic acquisition and analysis of crops can be carried out.

Description

technical field [0001] The invention relates to the technical field of field crop phenotype acquisition, in particular to a mobile phenotype cabin for field crop phenotype acquisition and analysis. Background technique [0002] Crop phenotypes are some or all of the identifiable physical, physiological and biochemical characteristics and traits produced by the interaction between genes and the environment, including the structure, composition, and growth and development of crops, which not only reflect expression regulation at the molecular level, but also It reflects the complex traits of plants such as physiology and biochemistry, morphological anatomy, and stress resistance. [0003] At present, field crop phenotype research mainly focuses on four aspects: obtaining plant type information and physiological parameters, identifying plants and detecting weeds, monitoring pests and diseases, and predicting yield. [0004] The development of functional genomics and genetic te...

Problems solved by technology

[0005] The traditional artificial climate chamber is generally used to monitor and control the growth environment of crops. It has the function of setting environmental factors such as temperature, humidity, illuminance, CO2 concentration, and soil moisture content. It can be applied to experiments such as genetic improvement of crops and new species cultivation. , although avoiding many constraints in the natural environment, it mainly relies on manual observation and measurement to describe the external characteristics of crops, so as to obtain the relationship between genotypes, environmental factors and crop phenotypes, for example, to obtain plant plant type information, such as using a ruler to measure plant height, leaf width, leaf length, etc.; based on personal experience, by observing the characteristics of roots, stems, leaves, flowers and fruits of crops and weeds, from color, traits, Identify and classify crops and weeds in terms of taste and other aspects; usually detect diseases and insect pests by human eye observation; predict yield through manual sampling methods such as visual estimation, measurement prediction and cutting prediction, etc. The above research work often relies on Manually detect individual traits of small sample plants, so the amount of data is limited, the efficiency is low, and it is difficult to carry out comprehensive analysis of multiple traits of plants, and the introduction of human factors can easily lead to errors in measurement data, which can be analyzed on a small scale, high cost, and time-consuming Laborious, lack of standardization and low measurement accuracy have become the bottleneck restricting the development of plant genome function analysis and molecular breeding
