我省大陆性气候早熟玉米区,是一个新玉米区。随着农业生产的发展,在河西走廊的沿山地区以及某些特定的地区,将可能形成一个早熟玉米带。为此,研究这一地区的玉米生长发育规律是非常必要的。试验于1976—1977年进行。供试品种为植株较矮小的玉单34(本地区推广良种)和植株中等的78—42×78—100,每亩6000株。一、株高、茎粗、叶片数的增长
Our province has a continental climate precocious corn area, is a new corn area. With the development of agricultural production, it will be possible to form a precocious corn belt along the mountainous areas of Hexi Corridor and some specific areas. Therefore, it is necessary to study the law of corn growth and development in this area. The test was conducted in 1976-1977. Test varieties for the shorter plant Yudan 34 (the promotion of elite in the region) and medium-sized plants 78-42 × 78-100, 6000 per acre. First, the plant height, stem diameter, the growth of the number of leaves
