摘要
采用正交试验法研究NPK复合肥不同施肥方案对红豆树叶绿素含量的影响。结果表明:施肥处理2(N500P200K250)能明显提高红豆树的叶绿素a、b及叶绿素a+b水平,而使叶绿素a/b明显下降;从光合速率和植物抗旱性的提高来说,处理2是本次试验的最佳施肥方案。
Effects of different designs of NPK compound fertilizer on chlorophyll contents in Ormosia hosiei Hemsl.et Wils were studied by using orthogonal experiment.The results showed that under treatment 2（N500P200K250） the contents of chl a,b and a＋b were significantly increased,whereas the chl a/b ratio was significantly decreased.In terms of the photosynthetic rate and plant drought resistance,the optimized fertilization design is the treatment 2.
