| 摘 要： | 对心里美萝卜生长动态及氮磷钾养分吸收规律的研究表明:播种后37～46 d（肉质根膨大初期）整株鲜、干重增长最快,吸收氮磷钾养分量最多。不同时期吸收量及比例不同。肉质根产量在75 812 kg/hm2时,平均每生产1 000 kg肉质根植株需吸收N 3.49 kg,P 0.39 kg,,K 3.46 kg,比例为1∶0.11∶0.99. 收获时植株吸收的各种养分主要贮存在肉质根中。

| Abstract: | The results of the studies on the growth trend and nutrient absorption characteristics of N,P,K in radish cv.Xinlimei showed that the fresh weight and dry weight of a whole plant increased rapidly in the initial period of product formation (37～46 d after sowing ) which was also the peak nutrient absorption stage of N,P and K. The amount and proportion of absorption were different in various growth stages. The amount of N,P and K absorbed by radish plants for producing every 1 000 kg of product was about 3.49 kg,0.39 kg and 3.46 kg respectively when the economic yield was 75 812 kg/hm2. The proportion of N,P,K absorbed was 1∶0.11∶0.99. The nutrients absorbed by a plant were stored mainly in the fleshy root at harvest. |
