摘要:

为了探明甘薯种植对盐碱地的改良效果,采用平板菌落计数方法研究了不同品种及农作方式对盐碱地甘薯根际土壤微生物的影响。结果表明,甘薯根际微生物数量的变化因品种不同而异,覆膜、适宜的种植密度(每亩约4 167株)、施加有机基肥均在不同程度上提高了土壤的微生物量。钾肥追肥试验结果表明,页面喷洒追肥比沟施对微生物数量的影响更显著,而钾肥以何种载体(K2HPO4或 KNO3)施加对其影响不大。

Abstract:

We employ plate counting to investigate the impacts of different varieties and farming methods on the rhizosphere soil microorganisms of sweet potato in order to reveal the improvement effect of sweet potato planting on saline and alkaline land. Results show that film, suitable density (4 167 plants/666.67 square meter) and organic fertilizer can improve the quantity of soil microbe to different extent. Results of potassium topdressing demonstrate that foliage spraying phosphoric fertilizer more significantly improve the quantity of rhizosphere soil microorganism than fertilizing potassium. However, potassium fertilized by K2HPO4 or KNO3 does not have significant impacts.

Key words: sweet potato, rhizosphere soil microorganism, saline and alkaline land, variety, farming method
