摘　　要：大麻收获时期是保证大麻雨露沤制成功的关键,为了黑龙江省大麻主产区大麻的适时收获、安全生产,研究了不同收获期对大麻全麻率的影响。结果表明:大麻全麻率与收获时期的关系呈"M"型曲线,第一峰值出现在出苗后67d,第二峰值出现在出苗后91d。不同收获时间对大麻全麻率有较大影响,黑龙江省第一至四积温带大麻收获时期为出苗后90～95d,第五积温带大麻收获为出苗后85～90d。The harvest time is the key to make the dew-retting successfully,for producing hemp timely harvest, safety in production in Heilongjiang province,the influence of different harvests time for total fiber content of hemp were studied. Taking three typical experiment points in Heilongjiang province as materials,the relation- ship between hemp linen rate and harvest time was described as M-curve; and the two peaks were on the 67th and 91tu day after seedling emergence respectively; different harvest time had a great influence on total fiber content total fiber content;the harvest time in 1-4 and 5 accumulated temperature zone of Heilongjiang prov- ince were on 90-95th day and 85-90th day after seedling emergence respectively.
