利用抗旱棚盆栽、小区、大田对春玉米常规品种的抗旱性鉴定指标进行比较研究。结果表明:在玉米抗旱性鉴定中胚根数、植株高度、ASI、保绿度、耐旱系数、RI(抗旱指数)和RI(修)可作为春玉米抗旱性的鉴定指标。
Drought-tolerant shed potted plants, plots and fields were used to compare drought resistance identification of conventional varieties of spring maize. The results showed that in the identification of drought resistance of maize, the number of radicles, plant height, ASI, greenness, drought tolerance index, RI (drought resistance index) and RI (repair) could be used as the identification indicators of drought resistance in maize.
