摘要
High yield and effective cultivation technic of winter-spring planting flax in south of China has been resulted after four years cultivation trials. The cultivation technic include seeds selection, early planting with suitable season and quantity, proper fertilization, fertilizer superaddition depending on early period growing situation,non-furrow and cover planting, weeding chemically, spraying growth regulator to avoid falling and harvesting at proper period. The yield of raw stem can reach above 4500-5250kg/ha. We also introduce the effective technology of south flax industrialization--rapidly retting. Using this technic, flax retting can be finished within 20hrs and dry stem rate, long flax rate and fiber quality can be improved, pollution can be reduced and raw stem income can be increased over 300RMB/T.The main flax byproduct-flax residue multiple utilizations mode and technology also is introduced to increase the additional value of flax.
