基于野外试验的玉米干旱脆弱性研究
Research on the Maize Drought Vulnerability Based onField Experiment
摘要
Abstract
Based on an artificial controlling field experiment, taking Huanghua city of Hebei Province base as the experimental site, the effect of different drought degree on maize growth of vegetative organs and biomass were analyzed, the physical maize drought vulnerability curves of the five stages were constructed.The results show that, the most impact growth period of maize plant height was the jointing stage.Root system was not sensitive to small degree of water shortage.The effect of drought stress at different stages of corn on the ground organs fresh weight is greater than that of root system.Under the low drought hazard-inducing degree, emergence-jointing stage has the highest biomass loss risk.Under the high drought hazard-inducing degree, jointing to tasseling stage has the highest biomass loss risk.关键词
