胡萝卜吸氮量与播后天数呈直线相关，吸磷钾量与播后天数呈Ｌｏｇｉｓｔｉｃ生长曲线。苗期吸磷钾量相对高于吸氛量。施用氮肥的利用率为２４．９％，磷肥利用率为１５．７％，钾肥的利用率为１６．６％。每生产１０００ｋｇ胡萝卜需吸收氮素３．５３ｋｇ，五氧化二磷１．５２ｋｇ，氧化钾６．９４ｋｇ。获得高产量亩施氮素１０ｋｇ，五氧化二磷５ｋｇ，氧化钾１５ｋｇ，亩密度２．７～２．８万株。亩产４２００ｋｇ以上的综合农艺措施为亩施氮素８．１～８．２ｋｇ，五氧化二磷４．５～５．４ｋｇ，氧化钾１４．３～１６．５ｋｇ，亩密度２．７～２．８万株。影响胡萝卜产量的因素主次顺序为：密度＞钾用量＞磷用量＞氮用量。
The nitrogen uptake of carrot was linearly correlated with the days after sowing, and the logarithm of P uptake and days after sowing showed Logistic growth curve. Potassium phosphorus intake at seedling stage is relatively higher than the amount of suction. The utilization rate of nitrogen fertilizer was 24.9%, the utilization rate of phosphate fertilizer was 15.7% and the utilization rate of potassium fertilizer was 16.6%. Each production of 1000kg carrots need to absorb nitrogen 3.53kg, phosphorus pentoxide 1.52kg, potassium oxide 6.94kg. Access to high-yielding acres of nitrogen fertilizer 10kg, phosphorus pentoxide 5kg, potassium 15kg, mu density of 2.7 to 28,000. The comprehensive agronomic measures of more than 4200 kg per acre are 8.1 ~ 8.2kg of mu nitrogen, 4.5 ~ 5.4kg of phosphorus pentoxide, 14.3 ~ 16.5kg of potassium oxide, and the density of mu is 2.7 ~ 2 Eighty thousand. The main factors affecting the yield of carrot were as follows: density> potassium content> phosphorus content> nitrogen content.
