以山核桃林地栽植的3种常见豆科牧草白三叶(T ri f olium repens Linn .)、紫云英(As‐tragalus sinicus L)和紫花苜蓿(Medicago sativ a L .)为对象,利用Li‐6400便携式光合仪对其植物叶片的气体交换参数进行了测定.结果表明,白三叶的光补偿点和光饱和点均最大,分别为24.16μmol/m2?s、758.00μmol/m2?s ,明显高于其它2个种;3种牧草的最大净光合速率同样存在显著性差异,其中白三叶为23.58μmol CO2/m2?s ,显著高于其它2个种(分别为10.55μmol CO2/m2?s、10.70μmol CO2/m2?s),说明了白三叶具有较强的光合能力.
以山覈桃林地栽植的3種常見豆科牧草白三葉(T ri f olium repens Linn .)、紫雲英(As‐tragalus sinicus L)和紫花苜蓿(Medicago sativ a L .)為對象,利用Li‐6400便攜式光閤儀對其植物葉片的氣體交換參數進行瞭測定.結果錶明,白三葉的光補償點和光飽和點均最大,分彆為24.16μmol/m2?s、758.00μmol/m2?s ,明顯高于其它2箇種;3種牧草的最大淨光閤速率同樣存在顯著性差異,其中白三葉為23.58μmol CO2/m2?s ,顯著高于其它2箇種(分彆為10.55μmol CO2/m2?s、10.70μmol CO2/m2?s),說明瞭白三葉具有較彊的光閤能力.

The gas exchange in leaves of three common Leguminous forages species in Carya cathayensis orchard including Tri f olium repens Linn .,Astragalus sinicus L .,Medicago sativa L ..were measured by using Li‐6400 portable photosynthesis system .The results showed that the light compensation point and light saturation point were 24 .16μmol/m 2 ?s ,758 .00μmol/m 2 ?s respectively in Tri folium repens Linn , great higher than other two species .In addition ,there was a significant difference on maximum net pho‐tosynthetic rate among these leguminous forage species .23 .58μmol CO2/m 2 ? s Tri f olium repens Linn was higher significantly than other two species (10 .55μmol CO2/m 2 ?s and 10 .70μmol CO2/m 2 ? s re‐spectively ) .In conclusion ,there was a stronger photosynthetic capacity in Tri f olium repens Linn among three leguminous forage species .
