本文研究了黄土丘陵区草地与农田中营养元素的含量及其迁移情况,结果表明,草地中有机质、全氮、水解氮的含量比农田的高,而有效磷、可交换钾和不可交换钾及微量元素要比农田的低。表明营养物质的迁移主要是从草地到农田。解决这一问题的措施是引种和选育优良牧草品种,增施氮、磷肥,调整氮、磷肥的比例。 The results showed that the content of organic matter, total nitrogen and hydrolyzed nitrogen in the grassland were higher than that in the farmland, and the contents of available phosphorus, exchangeable potassium and non-exchangeable potassium, Trace elements than farmland low. Indicated that the migration of nutrients mainly from grass to farmland. The solution to this problem is to introduce and select fine forage varieties, increase nitrogen and phosphate fertilizer, and adjust the proportion of nitrogen and phosphate fertilizer.
