Description
technical field:
The utility model belongs to agricultural biotechnologies process units field, relates to and identifies Rice Resistance megathermal device, the particularly megathermal system of a kind of evaluation Rice Resistance.
background technology:
Along with global warming, in rice growth China in season some areas, usually there will be abnormal high temperature weather.If be in the paddy rice of heading flowering stage, run into abnormal high temperature weather, heading flowering will be affected, cause Pollen Activity to decline, loose powder and pollen fertilization obstacle cause blooming, thereby ripening rate is declined to a great extent, cause paddy rice to drop in production over a large area, to peasant, bring heavy losses, national food safety and social stability are affected.
In production, between Different Rice Varieties there is notable difference to the susceptibility of abnormal high temperature in heading flowering period, and select and utilize the rice varieties that heading flowering period high temperature resistance is strong, be the most effective approach of guaranteeing Rice Production safety.Select and utilize the key of the rice varieties that heading flowering period high temperature resistance is strong to be rice ear sprouting period high temperature resistance authentication method and science and validity, especially, the difference of heading flowering period to the susceptibility of abnormal high temperature between Different Rice Varieties, requirement implements can effectively distinguish when rice ear sprouting period high temperature resistance is identified the sensitive degree of different cultivars.Realize the high temperature resistance of paddy rice is identified and needed to set up the megathermal identification apparatus of Rice Resistance or system.
At present, domestic to rice varieties Characters Identification, evaluation is only confined to output, resistance, the projects such as rice blast, bacterial leaf spot, meter Zhi, and rice ear sprouting period high temperature resistance characterization and evaluation is lacked to method and the device of systematic science.Retrieval situation shows, there is report to utilize artificial climate chamber device and interval sowing experimental rig to carry out the impact research of high temperature on ripening rate, China Paddy Rice Inst utilizes and can control the artificial climate chamber device of temperature and humidity and in conjunction with field experiment, carry out paddy rice Heat tolerance identification.These methods are roughly divided into " land for growing field crops interval sowing test for identification " and " evaluation of phytotron Processing Test " or both combinations." land for growing field crops interval sowing test for identification " and " evaluation of phytotron Processing Test " existing its advantage, but also exist significantly not enough." land for growing field crops interval sowing test for identification ", without facility, experimental enviroment is natural production condition, and kind sample is identified in enormous quantities, but tests required abnormal high temperature condition in particular year and be difficult to season be met, thereby is difficult to obtain qualification result; Phytotron is state-of-the-art weather conditions Artificial Control facility, can manually create hot conditions, but under complete natural conditions, air humidity during " evaluation of phytotron Processing Test " device in climatic chamber, variations in temperature, constituent of air, Air Flow etc. all have larger difference with paddy field environment, can disturb the fecundity of rice varieties, and construction, use cost are high, and experimental space is little, can not adapt to kind sample in enormous quantities and identify.Particularly, to with a collection of identification of species sample in same batch of evaluation, " land for growing field crops interval sowing test for identification " device, not only can not guarantee that in whole tassel blossom process, all accepting abnormal temperature processes, more can not make to obtain with a collection of identification of species sample the full adverse circumstance processing that abnormal temperature grows from weak to strong simultaneously; " evaluation of phytotron Processing Test " is although can arrange a plurality of abnormal temperature environment that grow from weak to strong, but prerequisite is to have a plurality of artificial climate chamber devices of counting equity with abnormal temperature environment set simultaneously, more can not realize the sensitive degree that the full adverse environmental factor of the indoor establishment of same artificial climate is distinguished different cultivars.Therefore, although the current domestic device that has some Rice Heading blooming stage heat-resisting quantities, but the deficiency of existing apparatus requires to create a kind of more effective practical rice ear sprouting period high temperature resistance identification apparatus, provide a kind of full adverse circumstance that approaches natural conditions to identify device or the system of rice ear sprouting period high temperature resistance.
