播种迟早对黄麻产量有显著影响。据1952年湖南省农业厅的試驗,在4月20日前播种的发生幼苗分枝开花現象(占总株数0.5％左右),中后期播种的生長的也不如5月上旬播种的良好,到5月下旬播种的,株高比适时播种的矮5尺以上。又广东农林厅1953年的調查,东莞第一区有些农民,在五月间冬播黄豆,收后播种黄麻,初期生長很好,但生育日数不足,到了收穫时,麻莖較矮細,最显著的是纖維細胞发育不足,麻皮薄,剝皮时亦不能剝到麻尾,因而影响产量甚大。1951年江西南昌上饒等地谷雨节播种的莢头麻迟不发芽,且出苗不齐,立夏以后播种的則出苗很正常。1954年浙江农科所的試驗,
Sowing sooner or later have a significant impact on the yield of jute. According to the experiment of Hunan Provincial Department of Agriculture in 1952, seedling flowering occurred in the sowing before April 20 (accounting for about 0.5% of the total number of trees), and the sowing in mid and late stage was not as good as the sowing in early May to May Late sowing, plant height than the timely sowing more than 5 feet short. In a survey conducted by the Guangdong Agriculture and Forestry Bureau in 1953, some peasants in the first district of Dongguan sowed soybean in the winter in winter in winter and harvested jute plants after harvest. The initial growth was good but the number of birth days was insufficient. At the time of harvest, the stems were shorter and thinner, Significantly lack of development of fibroblasts, hemp thin, peeling can not be stripped to Ma tail, thus affecting the yield is very large. 1951 Shangrao, Nanchang, Jiangxi and other places rainy season sowed nuggets Ma Ma sprout late, and the emergence of missing Qi, after the summer planting seeding is normal. 1954 Zhejiang Agricultural Experiment,
