Effects of Substitution of Commercial Bio-organic Fertilizer for Chemical Fertilizer on Yield Quality and Soil Nutrients of Sanhua Prunus salicina
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.
