通州宋梁路银红槭土壤现状及改良关键技术研究

Study on Soil Status and Key Improvement Technology of Acer rubium in Songliang Road,Tongzhou

针对通州宋梁路土壤偏碱性,可能导致银红槭秋季树叶未红先焦叶,甚至提前落叶的问题,采用化学改良、复合改良及缓释改良等方式对碱性土壤进行改良。结果表明:缓释改良短期内使银红槭的各项指标都达到最适生长范围,其中有机质提高75%,土壤总养分等均有提高,pH值降低6%达到6.96为银红槭生长最理想的pH值土壤。说明缓释改良对浅耕层(0~20 cm土壤)效果明显,并可保持相对稳定。

Aiming at the problem that the soil of Songliang Road in Tongzhou is alkaline,which may cause the leaves of Acer rubium to scorch before red in autumn,and even to lose their leaves in advance,the alkaline soil was improved by chemical improvement,compound improvement and slow release improvement.The results showed that in the short term,the organic matter was increased by 75%;the total soil nutrients were increased,and the pH was reduced by 6% to 6.96,which was the ideal pH soil for the growth of Acer rubium.This indicated that the slow release improvement had obvious effect on shallow tillage layer(0~20 cm soil) and kept relatively stable.
