摘　　要：试验以桃园人工种植的黄花苜蓿和自然禾本科杂草为材料,研究了一年中果园生草栽培下草种的鲜重、干重、大量元素和微量元素的含量。结果表明,果园冬季人工播种黄花苜蓿,来年4月份人工种植的黄花苜蓿每平方米比自然杂草收获的干物质多,同时有效锁定水分;6月、9月次之,12月最少。6月、9月自然禾本科杂草N含量比4月、12月人工种植的黄花苜蓿N含量高,铁含量则相反;全年镁含量逐渐增加。The planted Medicago falcata L. in winter and gramineae grassy weeds in peach orchard were used as test materials, and grass aboveground fresh weight, dry weight, macroelement and microelement contents were studied. The results showed that biomass of planted Medicago falcata L. which was cutted before anthesis in April next year, was more than that of weeds, and the water was so. Secondly, which was in June and September, the last was in December. N contents in weeds were higher, compared with planted Medicago falcata L., in June and September, hut Fe contents were opposite; Mg contents increased gradually in a year.
