| 摘 要： | 对心里美萝卜生长动态及氮、磷、钾、硫吸收规律的研究结果表明：植株鲜重、干重以出苗后６１～７５天增长最快；肉质根产量在６５５８９ｋｇ／ｈｍ２时，平均每生产１０００ｋｇ肉质根，植株需吸收Ｎ２．１１９ｋｇ、Ｐ２Ｏ５１．３０６ｋｇ、Ｋ２Ｏ２．４５１ｋｇ、Ｓ０．５８９ｋｇ，比例为１．００∶０．６２∶１．１６∶０．２８；出苗后３１～７５天是植株吸收养分的主要时期；收获时植株吸收的各种养分主要贮存在肉质根内。

| Abstract: | The growth dynamics of fresh weight and dry weight and nutrient absorption of N,P,K and S were studied radish cultivac Xinlimei. The reasults showed that the growth rate of the plant fresh weight and dry weight reached its peak in 61 75 days after emergence. On the average 1000 kg to proot required 2.119 kg N,1.306 kg P2O5,2.451 kg K2O and 0.589 kg S. The absorption peak occured in 31 75 days after emergence. |
