摘　　要：以水萝卜为实验材料,用纸上发芽法进行实验,设置全光(L1)、半遮光(L2)、黑暗(L3)三种不同的光照处理,各光照处理下设置5个氮肥处理组(质量浓度分别为0、25、50、75、100 mg/L),研究对水萝卜种子萌发及幼苗生长的影响。结果表明,在黑暗条件下,施加适合质量浓度的氮肥会增加幼苗重量,从而提高幼苗质量,也证明了环境中生态因子的综合作用与补偿性作用。The seeds of raphanus sativus were taken as test material,and hydroponic experiments were carried out in perti dishes.Three different light treatments were set up:full light(L1),semi-shade(L2),and darkness(L3).Five types of nitrogen fertilizers were set under each light treatment.The effects of concentrations(0,25,50,75,100 mg/L)on R.sativus seed germination and seedling growth were studied.The results showed that under dark conditions,applying nitrogen fertilizer at a suitable depth will increase the weight of seedlings,thus improving the quality of seedlings.It also proves the comprehensive and compensatory effects of ecological factors in the environment.
