芝麻是一种需肥较多的经济作物，据测算，每生产100公斤麻籽，需从土壤中吸收纯氮8．3公斤、五氧化二磷2．1公斤、氧化解4．4公斤，氮、磷、钾比例约为1：0.3：0.5。芝麻各生育期的需肥规律是：幼苗期生长缓慢，根系吸收力弱，吸收养分的比例较小，需肥量约占全生育期需肥总量 Sesame is a need more fertilizer economic crops, it is estimated that each production of 100 kg of hemp seeds, need to absorb 8.3 kg of pure nitrogen from soil, phosphorus pentoxide 2.1 kg, 4.4 kg of oxidative decomposition, Nitrogen, phosphorus and potassium ratio of about 1: 0.3: 0.5. Sesame growth pattern of the need to fertilizer is: seedling growth is slow, the root absorption is weak, the proportion of nutrient absorption is small, accounting for the total amount of fertilizer required during the whole growth period
