摘要
2004年台安县洪家农牧场引进加拿大优质苜蓿草进行种植实验。通过清种、林地间作和不种苜蓿草对比实验,对土壤速效氮、速效磷、速效钾、有机质、PH值、含水量进行分析,得出种植苜蓿草所产生的生态环境效益和经济效益。此项实验结论说明,紫色苜蓿是牧草之王,可促进养殖业的发展,对改善生态环境,防止土壤沙化和水土流失,改善农业结构,实现生态良性循环起到积极的促进作用,对改善生态环境起到了良好的示范作用。
In 2004, high - quality alfalfa was introduced from Canada and growing experiment was carried out on Hongjia Livestock Farm in Taian County. Based on the comparison experiments of clean planting, intercropping, and non - planting alfalfa, quick -acting nitrogen, phosphorus, potassium, organic matter, Ph value and water content in soil were analyzed and results of eco -environmental effect and economic benefit from growing alfalfa were obtained. The experimental conclusion showed that alfalfa, ＂the king of herbage＂, could promote development of livestock breeding industry and played a positive stimulating part as well as an exemplary role in improving ecological environment, preventing desertification of soil and water loss and soil erosion, adjusting agricultural structure and realizing virtuous ecological circle.
