摘　　要：试验于2017—2019年持续3年在盐碱土壤中施入不同用量(666.7m^(2)分别施用1、2、4、6、8、10 t)的中草药专用有机肥,以间作模式种植薄荷和皂角,于2019年对薄荷的农艺性状和产量进行调查分析。结果表明:与不施肥对照相比,持续3年施用有机肥后头刀和二刀薄荷的株高、茎围、叶面积、鲜重、干重和产量显著提升,而同期只施氮磷钾复合肥80 kg(666.7m^(2)用量)处理仅提升头刀薄荷的农艺性状和产量。化肥处理头刀薄荷茎围、鲜重和干重优势显著;专用有机肥6 t处理叶面积最大,10 t处理株高最高。有机肥处理的二刀薄荷各项指标显著优于化肥处理及对照,其中6 t和8 t处理的各指标优势较显著。6 t处理头刀鲜薄荷产量最高,666.7m^(2)达3572.4 kg,干重为608.4 kg。以上结果表明盐碱地持续施用中草药专用有机肥可以显著提升薄荷农艺性状和产量,666.7m^(2)推荐用量为6 t。From 2017 to 2019,three-consecutive-year application of different gradients of special organic fertilizer for Chinese herbal medicine were conducted for mint(Mentha haplocalyx Briq.)in saline-alkali soil.The application rates were set as 1,2,4,6,8 and 10 t per 666.7 m^(2),and the agronomic characters and yield of mint were investigated in 2019.The results showed that compared with the control,the application of special organic fertilizer could significantly increase plant height,stem circumference,leaf area,fresh weight,dry weight and yield of the first-knife and second-knife mint,and the application of only chemical fertilizer at 80 kg per 666.7 m^(2)increased the agronomic characters and yield of the first-knife mint.Under chemical fertilizer,the stem circumference,fresh weight and dry weight of the first-knife mint were significantly higher;under special organic fertilizer,the 6-t treatment gained the largest leaf area and the 10-t treatment got the highest plant height.The traits of the second-knife mint under special organic fertilizer were significantly better than those under chemical fertilizer and control,especially the 6-t and 8-t treatments.The yield of the first-knife mint under the 6-t special organic fertilizer treatment was the highest as 3572.4 kg per 666.7 m^(2)with the dry weight as 608.4 kg per 666.7 m^(2).In conclusion,the continuous application of special organic fertilizer for Chinese herbal medicine in saline-alkali soil could significantly improve the agronomic traits and yield of mint,and the recommended application amount was 6 t per 666.7 m^(2).
