以中熟品种＂９７１＂和中熟偏早品种＂８４５２＂为材料，进行不同生育期收获与产量、品质关系的研究。研究结果表明：黄麻要到盛花至工艺成熟期品种的种性（纤维产量和品质）才能得到充分发挥。因此在选育高产、优质的品种时，必须根据不同地区的耕作制度，注意选育生育期适当的品种，使在收获时生育期能达到盛花至工艺成熟期。 The medium maturity cultivar “971” and the moderate maturing early cultivar “8452” were used to study the relationship between yield and quality at different growth stages. The results showed that the species (fiber yield and quality) of jute varieties should reach their full maturity until full maturity. Therefore, breeding high-yielding, high-quality varieties, according to different regions of the farming system, pay attention to breeding the appropriate varieties of growth period, so that the harvest can reach full bloom during the growth stage to maturity.
