- 摘要:
- 为了解有机质材料对浑河河滩土壤的理化性质作用的改良作用，在河滩土壤中添加不同比例的有机质材料，测定不同土样的土壤菌类构成及数量、土壤营养情况和植物根系生长情况。结果表明：在浑河河滩中添加有机质材料可以提高土壤中微生物的种群数量，可以不同程度地提高土壤速效氮、磷、钾的含量。单一有机质材料、河滩土对根系的生长效果较差。之后随着有机质材料添加的越多，根系生长效果越佳。在基土比5∶5时，效果最佳，之后随着有机质材料的添加，根系生长渐弱。
- Abstract:
- In order to understand the effect of organic materials on improving the physical and chemical properties of Hunhe floodplain soil,adding different amounts of organic materials into the floodplain soil,and determined the composition and quantity of soil microorganism,soil nutrition and plant root growth.The results showed that adding organic materials into Hunhe floodplain soil could increase the number of microorganisms in soil population and increase the content of quick-impact N,P,K.The effect of single organic materials and floodplain soil on plant root growth was poor.With the addition of organic materials ,the root growth was better.Under the combination ratio of 5∶5,the effect was best,then with the addition of mulch,the root growth decreased.
