研究了胡萝卜肉质根产量７３１４９．７ｋｇ／ｈｍ２条件下其鲜重、干重变化及Ｎ，Ｐ２Ｏ５，Ｋ２Ｏ，Ｓ的吸收规律。结果表明：植株鲜重、干重增长高峰期在苗龄４６～６０ｄ（其中肉质根在４６～１０５ｄ，叶在３１～６０ｄ）；每生产１０００ｋｇ肉质根植株需吸收Ｎ１．３８ｋｇ，Ｐ２Ｏ５１．３７ｋｇ，Ｋ２Ｏ２．２３ｋｇ，Ｓ０．１７ｋｇ，其比例为１．００∶０．９９∶１．６２∶０．１２；植株吸收的Ｎ，Ｐ２Ｏ５，Ｋ２Ｏ主要贮存在肉质根内，Ｓ主要贮存在叶内；植株对４种养分吸收强度最大的时期均在苗龄４６～６０ｄ。 The changes of fresh weight and dry weight and the absorption of N, P2O5, K2O and S under the condition of 73149.7kg / hm2 root yield of carrot were studied. The results showed that fresh weight and dry weight growth peaked at the seedling age of 46-60 days (the fleshy roots were 46-105 days and the leaves were at 31-60 days); N1.38kg and P2O51.37kg were needed for producing 1000kg fleshy roots, K2O2.23kg, S0.17kg, the ratio of 1.00: 0.99: 1.62: 0.12; plant absorbed N, P2O5, K2O are mainly stored in the fleshy root, S is mainly stored in the leaves; plants The four kinds of nutrient absorption intensity of the maximum period of 46 to 60 days of age.
