黄麻发生早花以后,植株矮小,分杈多,麻皮薄,产量品质都低。根据試驗資料,如果每株少长一尺,每亩二、三万株左右,少收生麻皮50—60斤;早花的黄麻一般植株高度仅三、四尺,比一般正常生长的麻株矮四、五尺,由此推算,每亩减产200—300斤。这个損失是很可观的。近几年来南方黄麻产区,都发生不同程度的早花現象。因此,黄麻早花是生产上亟待解决的一个重要問
Jute occurred after early flowering, plant dwarf, bifurcation, hemp thin, yield and quality are low. According to the experimental data, if each plant less one foot long, about two or three million per acre, less income hemp 50-60 kg; early flowering jute plants generally only three or four feet higher than the normal growth of hemp Four plants short, five feet, which projections, cut 200-300 pounds per mu. This loss is very substantial. In recent years, southern jute producing areas, have occurred at different levels of early flower phenomenon. Therefore, the early jute flower production is an important question to be solved
