大多数粒用高粱的生产地区经常发生不同持续时间和强度的干旱,并且常常伴随着异常高温。近年来人们已把新的研究目标集中到利用有限水源保持高产方面。本文考察粒用高粱对低土壤水分利用率和高温的反应,并且讨论改善这些逆境不利影响的方法。 Most grain sorghum production areas often experience droughts of different durations and intensities, often accompanied by unusually high temperatures. In recent years, people have focused their new research efforts on the use of limited water sources to maintain high yields. This article examines the response of grain sorghum to low soil water use efficiency and high temperatures and discusses ways to improve the adverse effects of these stresses.
