Description

Wheat cold resistance indoor identification platform with adjustable temperature light and position effect elimination Technical Field The utility model relates to the field of indoor wheat identification, in particular to an indoor wheat cold resistance identification platform with adjustable temperature and light and capable of eliminating position effect. Background The indoor identification of the cold resistance of the wheat is a technical method for systematically evaluating the cold resistance of wheat varieties by simulating low-temperature stress under controllable environmental conditions. According to the method, parameters such as temperature, illumination, humidity, wind speed and the like are accurately regulated and controlled by using an artificial climate box or a customized culture device, multidimensional evaluation is performed through physiological indexes, biochemical indexes and morphological indexes, standardized and high-throughput identification of the cold-resistant phenotype is finally realized, the limitation that the traditional field identification is influenced by environmental fluctuation is overcome, and reliable data support is provided for cold-resistant variety breeding and mechanism research. Traditional wheat cold-resistant appraisal adopts nature low temperature environment to plant or simple and easy incubator mostly, receives the interference that temperature control is inaccurate, wind speed is uncontrollable and environmental parameter is unstable often to current equipment is difficult to eliminate the position effect, can not provide intelligent control of environment and dynamic monitoring demand, leads to the repeatability extremely poor, is difficult to satisfy the accurate appraisal demand of wheat cold resistance.
