为探究樱桃萝卜的合理施肥技术,利用盆栽试验开展了樱桃萝卜营养特征的研究。结果表明:樱桃萝卜干物质积累量在出苗后40d达峰值,地上与地下部分干物质积累量分别为0.0211g/株、0.1375g/株。樱桃萝卜对氮素吸收呈现慢—快—慢的趋势,在出苗后20d氮素积累量进入快速增长阶段,樱桃萝卜对磷素和钾素的吸收态势基本一致,均表现为出苗后20~40d吸收速率逐步递增。对氮、磷、钾的积累量均表现为:地下部分﹥地上部分。在试验条件下,在生育期为35d时收获,每生产1kg樱桃萝卜块根鲜重,需要N 4.84g,P2O50.54g,K2O 8.07g,即N∶P2O5∶K2O=9∶1∶15。
In order to explore the reasonable fertilization technology of cherry radish, pot experiment was carried out to study the nutritional characteristics of cherry radish. The results showed that the dry matter accumulation of cherry radish peaked at 40 days after emergence, and the dry matter accumulation of aerial parts and underground parts were 0.0211 g / plant and 0.1375 g / plant, respectively. Cherry radish showed a slow-fast-slow-down trend in nitrogen uptake, and nitrogen accumulation reached a rapid growth stage 20 days after emergence. The absorption of phosphorus and potassium by cherry radish was basically the same, both of which showed 20 to 40 days after emergence Absorption rate gradually increased. The accumulation of nitrogen, phosphorus and potassium showed as follows: underground part> aerial part. Under the experimental conditions, harvesting at the 35th day of the growth period yields N 4.84g, P2O50.54g and K2O 8.07g, ie N: P2O5: K2O = 9: 1: 15 for each fresh weight of 1kg of cherry radish.
