摘  要:
通过对人工种植黄花草木樨样地的监测,根据土壤养分含量的变化研究了改良退化土壤的效果。在种植黄花草木樨后,除了土壤全钾和速效磷含量下降以外,土壤有机质、水解性氮、全氮、全磷、速效钾养分含量皆明显增加。磷、钾下降的原因与黄花草木樨生长发育过程的需肥特性有关。在黄花草木樨生长发育过程中,应该注意追施磷、钾肥,可达到“以磷增氮”,“以钾促氮”的目的。实践表明,种植黄花草木樨这一技术具有改良土壤,培肥地力的作用,它是干旱、半干旱地区改良退化土壤的一种优良牧草。

摘  要:
The effect of Melilotus officinalia on improving degraded soil is studied according to the change in nutrient content of soil after planting. The results show that planting Melilotus officinalia can increase soil organic matter, total N,hydrolytic N, total P, and available K significantly, but decrease available P and total K. The reason for the latter decreases is that Melilotus officinalia needs phosphate fertilizer and potassium fertilizer to satisfy its growth. Therefore, during the growth of Melilotus officinalia, phosphate fertilizer and potassium fertilizer should be applied reasonably in order to boost nitrogen levels in the soil. This biotechnology technique functions to improve saline alkaline soil and increase the fertility of soil. The experiment indicates that Melilotus officinalia is an excellent kind of pasturage for improving the degraded soil in arid and semiarid regions.
