| 摘 要： | 试验采用盆钵栽培方法,通过施入不同量的中药渣,同时配合施用适量无机肥后,种植春、秋两季玉米。观测玉米长势情况、根系活力情况、养分吸收情况、含糖量、产量以及收获后土壤理化性状的变化情况,研究中药渣的改土效果,为后期的田间试验确定合理的中药渣施用量提供理论依据。试验结果表明,中药渣对土壤理化性质有明显改善作用,其与土壤按照1∶1、1∶2、1∶3的比例添加可使土壤有机质含量增加186.0%～275.8%,且使土壤更疏松;增施中药渣促进玉米根系生长,使春、秋玉米产量分别提高81.2%、28.9%。

| Abstract: | Corn seeds were grown in spring and autumn with pots,and soil was amended by different amount of Chinese medicine residues and proper chemical fertilizers.According to growth,root activities,nutrients uptake,sugar contents,yield of corn,and changes of soil physico-chemical characteristics after harvest,the effects of Chinese medicine residues on soil amelioration were investigated,so as to provide evidence on field experimental study on reasonable applications of Chinese medicine residues in soil.Results sh... |
