摘要:
沙打旺(Astragalus adsurgens)人工草地通常生长数年后即自然衰退。由于沙打旺具有强烈的土壤干燥化作用,在衰退草地上播种深根性豆科牧草生长不良;而播种的浅根禾本科牧草则生长正常,这就为衰退后草地的特续发展提供了人工更新草种,并为在不宜农作的土地上建立永久人工草地打下了基础。
Abstract:
Artifical Astragalus adsurgens grassland usually declines naturally after some yearsof the gowth.In the declind grassland,long root legumes grasses don’t grow well,but shortroot cereals grasses grow best,because Astragalus adsurgens has a strong soil-dryed action.These results can supply artifical alternating grass varieties for the sustainable development ofdeclined grassland,and form a basis for building permanent artifical grassland on unsuitablefarmland.
