研究在某一地区小麦主要品种的各个生育时期,与当地农业生产关系密切。一是可以根据品种的主要发育时期,制订生产计划和相应的栽培技术措施;二是从不同品种生育时期的分段鉴定,可以看到类型和品种差别的实质,并可以根据不同生育时期长短互补,进行亲本选配,有计划、高效率的育种。武功县在陕西关中平原中部(北纬34°20′东经108°,海拔500公尺左右),属华北平原中熟冬麦区,实践证明,在武功育成的良种(如碧蚂1号、丰产3号、小偃4号等)对陕西关中、河南、山西、河北以及山东、安徽的部分地区均有一定的适应性,所以研究武功小麦的生育期,对外地引种也有一定意义。试验于1975年至1976年设在本所官村试验场(头道源,旱肥地)正常秋播了50个有代表性的品种或新品系,并对各个主要发育
Study in a certain region of the main varieties of wheat at various growth stages, and the local agricultural production are closely related. First, according to the main developmental stages of the species, formulate production plans and corresponding cultivation techniques and measures; Second, from different stages of the reproductive stage identification, you can see the essence of the type and variety differences, and can be complementary to the length of the different reproductive period , The parent matching, a planned and efficient breeding. Wugong County is located in the central part of the Guanzhong plain in Shaanxi Province (latitude 34o 20 ’north longitude 108 ° and elevation 500 m), which belongs to the middle-maturing winter wheat area of North China Plain. Practice has proved that the cultivars (such as Bi Ma 1, No. 4 and Xiaoyan No. 4, etc.) have some adaptability to parts of Shaanxi, Guanzhong, Henan, Shanxi, Hebei, Shandong and Anhui. Therefore, it is of great significance to study the growth period of Wugong wheat and introduce it to other places. During 1975-1976, 50 representative varieties or new lines were normally sowed in autumn at Gucun Village Experimental Station (Headway, Dry Land)
