摘要
为减少化肥的过量施用,提高肥料利用率,研究生物有机肥对三华李生长的影响和中等土壤肥力水平下商品有机肥施用对三华李生长的效果及替代化肥比例,探索适宜三华李的商品有机肥替代化肥技术模式,构建有机肥科学施用体系,在贺州市八步区进行了生物有机肥替代化肥在三华李上的应用试验,结果显示,施用生物有机肥后,减少部分化肥用量对三华李的产量和品质均有提高;且施用生物有机肥后土壤有机质含量有所增加,有助于耕地的可持续利用.文章详细介绍了试验过程及结果,为三华李的优质高产提供借鉴.
Abstract
In order to reduce the excessive application of chemical fertilizer and improve the utilization rate of fertilizer,the effects of bio-organic fertilizer on the growth of Sanhua Prunus salicina,the effects of commercial organic fertilizer application on the growth of Sanhua Prunus salicina and the proportion of substitute chemical fertilizer under medium soil fertility level were studied,the technical model of replacing chemical fertilizer with commercial organic fertilizer suitable for Sanhua Prunus salicina was ex-plored,and the scientific application system of organic fertilizer was constructed.The application test of bio-organic fertilizer instead of chemical fertilizer in Sanhua Prunus salicina plant was carried out in Babu District of Hezhou City.The results showed that the yield and quality of Sanhua Prunus salicina were improved by reducing the amount of bio-organic fertilizer.At the same time,the ap-plication of bio-organic fertilizer increased the content of soil organic matter,which could improve the quality of cultivated land and contribute to the sustainable utilization of cultivated land.
