玉米是高产作物,发展玉米产业对保障国家粮食安全、促进经济社会协调发展具有举足轻重的作用。因地制宜增大玉米种植密度是进一步提高玉米产量的必然选择。但密度增大逆境胁迫会加重,因而耐荫湿研究尤为重要。该文概述了开展玉米耐荫湿研究的现状,提出了研究思路。 Corn is a high-yield crop and the development of the corn industry plays an important role in ensuring the national food security and promoting the coordinated development of economy and society. According to local conditions to increase corn planting density is to further increase corn production inevitable choice. However, increasing the density will increase the stress of stress, so shade-resistant research is particularly important. This paper summarizes the current status of research on shade-resistant maize and puts forward research ideas.
