(?)麻为我国主要麻类作物之一,品种资源丰富,不同品种间在成熟期、株高、茎粗、出麻率及单株纤维重以及生理特征、特性上有显著差异。广泛搜集(?)麻品种材料进行利用研究,具有重要的学术意义。(?)麻品种观察,采用条播,行长15尺,行距2.5尺,每品种种2行或3行,对照品种为华北大青杆。(?)麻品种比较试验,行长、行距及对照种与品种观察同;1959年采用3行区,1960年采用4行区;重复次数1959年4次,1960年3次;每亩栽植密度约一万株。
(?) Hemp is one of the main hemp crops in our country. The varieties are rich in resources. There are significant differences in maturity, plant height, stem diameter, hemp yield, individual fiber weight and physiological characteristics and characteristics among different varieties. It is of academic significance to extensively collect (?) Hemp species for utilization research. (?) Hemp species observation, the use of broadcast, the governor 15 feet, line spacing 2.5 feet, each species 2 or 3 kinds of lines, the control species is the North China Daqing pole. (?) Hemp varieties of comparative trials, governors, row spacing and the control species and species observed the same; 1959 with 3 rows of districts, 1960 with 4 rows of districts; repetition number 1959 4 times, 1960 3 times; About ten thousand.
