摘　　要：龙胆草施用不同肥料和覆盖遮阳网的试验表明 :施入磷肥(磷酸二铵 +过磷酸钙)>(0.0225+0.0225)kg·m-2 时 ,龙胆草增产幅度为12.5%;施入农家肥6～7.5kg·m-2,龙胆草增产幅度为11.11%～13.95%。龙胆草覆盖遮阳网 ,斑枯病发病时间较裸地栽培晚15d,发病率为23.4%;比裸地栽培增产39.97 %。The results from plot experiments showed that the yield of roungh gentian was increased by 12.5% under the application of diammonium phosphate and calcium superphosyhate(>0.0225+0.0225kg·m-2),and 11.11%～13.95% in the manure application treatments(6～7.7kg·m-2).Under the treatments with sun-shading net,the occurrence time of septoria leaf spot was delayed 15 days,with the rate of 23.4%.The yield was raised 39.97% compared with the uncovered treatment.
