一、品种来源及其主要特点多穗高梁本名恆佳利,原产于南菲洲,几年前在辽宁、河北等省有另星栽培,因其适应性强,产量高,因而种植范围和面积迅速扩大。为了测定本品种在陕北地区的适应性,我们于1958年曾向中国农业科学院征得少量种子在绥德试种,表现非常良好,群众要求扩种。但该年引进的种子已很混杂,植株分离现象比较严重,为了确保品种的纯度59年又从河北秦皇岛调入良种数十斤继续试种。本品种在绥德地区5月下旬播种,9月中旬成熟,生育期110天左右。植株矮小,高度1.2—1.5米,茎粗1.2—1.4厘米,幼苗略带紫色;杆硬不易例伏,分蘖力强,在密植的情况下每株可分蘖2—3个;如水肥充足,留苗稍稀,分蘖可达5—6个,穗为密穗形,顶端稍 First, the source of varieties and their main characteristics Multi-spike sorghum, whose real name is Heng Jia Li, native to South Philippines, a few years ago in Liaoning, Hebei and other provinces there is another star cultivation, because of its adaptability, high yield, and thus planting range and The area is rapidly expanding. In order to determine the adaptability of the cultivars in northern Shaanxi, we obtained a small amount of seeds from the Chinese Academy of Agricultural Sciences in Sui Te for planting in 1958. The performance was very good and the masses demanded expansion. However, the introduction of the seed that year has been very mixed, the phenomenon of plant segregation is more serious, in order to ensure the purity of varieties 59 years from Qinhuangdao, Hebei transferred hundreds of pounds to continue breeding. This species is sown in late May in Suide, mature in mid-September, and the growth period is about 110 days. Plant short, height 1.2-1.5 meters, stem diameter 1.2-1.4 cm, purple seedlings; hard hard case, strong tillering capacity, in the case of close planting each tiller 2-3; such as adequate water and fertilizer, leaving Slightly thin seedlings, tillers up to 5-6, the ear is a dense spike, the top slightly
